Green Bay Turns Down the Heat; Still Too Hot in Arizona

Wisconsin is already prepping for football weather, and the Southwest feels like the Southeast. WOVM-FM (Green Bay) OM Shaun Shouldeen is from Georgia, and doesn’t mind the cold & dry. “High 60’s plus no humidity equals perfection to this Georgia boy!” KKYZ-FM (Sierra Vista, AZ) OM Jeff Davenport says, “We are hot and humid with highs in the 90’s here, but everyday we are getting monsoon storms. We like the rain, but our radio towers don’t like the lightning!”

Strong Cold Front Igniting Severe Storms in Mid-Atlantic and Northeast

A severe weather outbreak is currently underway across portions of the Mid-Atlantic region into the Northeast where a strong cold front associated with a potent trough is causing a line of storms to explode rapidly.

An unstable environment is currently in place across a large spatial region from North Carolina into Northeastern PA and Southwestern New York where a strong cold front is generating a massive line of thunderstorms. The line will be capable of producing widespread destructive gusts and isolated large hail. Isolated weak / brief tornadoes and[or] embedded circulations within the line are also possible. A Severe Thunderstorm Watch (WW #423) has been issued by the Storm Prediction Center including the regions of Southwest Connecticut, District of Columbia, Delaware, Central and Eastern Maryland, Northern North Carolina, New Jersey, Southeast New York, Southeastern PA, Central and Eastern Virginia, as well as the Eastern West Virginia Panhandle and the Coastal Waters until 9:00pm EDT. Another Severe Watch is likely to be issued for southern New England concerning the threat for damaging winds and large hail. Monitor your local news and radio stations for real-time information regarding the threat this afternoon.

Morning sounding observations across the region have indicated a very warm and moist boundary, where southwesterly unidirectional winds strengthen abruptly in the low-levels of the atmosphere. Given that the winds remain unidirectional into the upper levels, the main storm mode this afternoon will be widespread damaging winds. Although as aforementioned, isolated large hail events are likely within the most intense storm clusters within the line as it propagates eastward toward the New York City – Philadelphia – Washington D.C. megapolis corridor. Soundings indicate CAPE (measure of instability) around 2,500 – 3,500j/kg, which will amalgamate storms into a larger scale as the afternoon progresses. Storm motion across the region appears to be relatively out of the west and will be advancing eastward at about 40-50mph. Updraft heights will be conducive for storms to also produce continuous and deadly cloud-to-ground lightning. Be sure to move indoors when severe storms occur. The severe threat will begin to diminish in the evening as daytime surface heating is lost and the boundary layer begins to cool.

Remember to have your NOAA Weather Radios turned on and to tune into your local news and radio stations as they can provide real-time information when severe weather impedes your area.

 

 

 

 

 

 

 

 

 

 

 

 

 

HURRICANE ARTHUR EYES NORTH CAROLINA, EXPECTED TO STRENGTHEN

HURRICANE ARTHUR CONTINUES TO MOVE NORTH-NORTHEAST TOWARD THE COAST OF NORTH CAROLINA AND IS EXPECTED TO STRENGTHEN AFTER LANDFALL TONIGHT.

As of the 8pm EDT advisory from the National Hurricane Center, Hurricane Arthur had maximum sustained winds of 90MPH with a minimum pressure of 977mb. Arthur continues to move north-northeastward and is starting to accelerate, now moving at 15mph. Recent visible satellite and infrared imagery has shown a well defined eye with explosive convective cumulus towering around the eye-wall, with overshooting tops on the eastern and northern quadrants of the eye-wall. These intense bands and clusters within the eye-wall are locations of the strongest surface winds, and hurricane force winds will be imminent along the Outer Banks and Barrier Islands of North Carolina. Further intensification of Arthur is expected to Category-2 status near or after landfall on the North Carolina coastline. Landfall is expected in the next few hours as the eye is currently passing southeast of Wilmington, North Carolina (as of 8:01pm EDT). That said, storm surge and inland flooding are now of major concern. Storm surge forecasts as per the NHC experimental Storm Surge maps are indicating 6+ feet of storm surge throughout the Barrier Islands into the North Carolina mainland. Additionally, major inland flooding will be imminent. Training bands of very heavy rain where increased convergence is occurring will be likely as Hurricane Arthur makes landfall. Current indications of 4-6 inches of rain are likely, with 8+ inches locally expected. As per the Weather Prediction Center, some rain bands have unloaded over an inch of rain in 40 minutes in some areas. A Tornado Watch related to Hurricane Arthur is also effective for Coastal North Carolina until 2am EDT where some tornadoes and waterspouts may occur, a few of which may be intense due to an increase in low-level wind shear.

Further north, influences of Hurricane Arthur are already under way in the Mid-Atlantic and Northeastern states. Moisture transport ahead of Hurricane Arthur is causing a major influx of moisture throughout a corridor along Appalachia. Storm mergers and training bands of very heavy rain are ongoing and will be possible the rest of the evening as Hurricane Arthur continues to trek north-northeastward. Ongoing thunderstorms and storms that fire in the evening as well will have the potential to produce extremely heavy rain fall rates, some in excess of 1-2 IN/HR. Widespread Flash Flooding is highly likely throughout the Mid-Atlantic into the Northeastern states.

Additionally, latest Ocean Prediction Center analyses are showing significant wave heights just off the North Carolina shorelines. Waves in some areas are in excess of 20-feet, with some reaching near 30-feet. RIP CURRENT DANGER WILL BE EXTREMELY HIGH, POSSIBLY LIFE-THREATENING, EVEN AFTER THE HURRICANE HAS PASSED. DO NOT ENTER THE OCEAN UNTIL THE BEACH PATROL AND/OR LIFEGUARDS HAVE DEEMED IT SAFE TO DO SO. High Surf Advisories have also been issued further north along the Virginia / Maryland / Delaware coastlines where waves may be approaching the 6-8ft mark. Beach erosion can be expected along the North Carolina coast and further northward even though Arthur is expected to veer out to sea.

MAJOR Severe Weather Outbreak Underway for the Mid-West

A major severe weather outbreak is underway for the Middle and Upper Mississippi River Valley today into the evening. The potential exists for widespread damaging winds, extremely large / destructive hail and tornadoes, some of which may be intense.

swo_sm_201406301429

Severe Weather Outlook risk zone for Monday, June 30th. Image courtesy of: NOAA / NWS SPC

 

Morning surface analysis and observed soundings across the Mid-West have indicated a volatile environment conducive for widespread severe thunderstorm development that is already underway, and will persist into the afternoon and the night. The 12z (7am CDT) observed sounding from Quad Cities, Iowa, sampled backed southeasterly surface winds before an abrupt shift to southwesterly in the lowest levels of the atmosphere. That said, CAPE indices are expected to rise to 4,000-5,000j/kg, delineating an extremely unstable boundary layer. Gradually with height, winds become more unidirectional from the west. The clockwise wind curvature from the surface to low-levels and strong winds aloft yields to the possibility of numerous tornadoes, some of which may be intense throughout the Mid-West this afternoon within the discrete supercells. Aside the tornado threat, the extreme moisture content throughout the region, coupled with strong wind parameters will also be supportive of damaging to hurricane force winds within stronger supercells. The wind threat will grow more upscale into the afternoon and evening, congealing into a squall line and[or] derecho event. Storm mergers and consolidation are likely this afternoon and regardless of whether or not storms are discrete or linear, supercells will have the potential to produce GIANT hail given the extreme instability and wind fields, which will allow for updrafts to sustain themselves for long periods… Long-lived supercells are possible.

Current visible satellite imagery is already showing widespread and explosive convective growth across eastern Nebraska into Iowa. With strong surface heating in areas to the east that are not currently exposed to complete cloud cover, robust atmospheric destabilization is already underway. Despite the ongoing activity, the longevity of the events today will continue to persist and will evolve into a more widespread and hazardous event into the night. Aside the the main storm modes, flash flooding is also of concern given very high values of moisture present in the current state of the atmosphere. This evening after storms conglomerate, widespread flash flooding appears to be very high threat. If you see a roadway that is flooded, turn around and do not drown.

If you have not already done so, now is the time to prepare and have an action plan ready. Be sure to have your NOAA Weather Radios turned on and tune into your local news media and radio stations to receive real-time hazardous weather information when it impedes your area.

SIGNIFICANT Severe Weather outbreak Likely Today in central Plains

A significant severe weather outbreak is likely today across the middle to upper Mississippi River Valley into the central Great Plains. The potential exists for very large / damaging hail,  damaging winds and a few tornadoes.

swo_sm_201406291329

Severe Weather Outlook zone for Sunday, June 29th, 2014. Image courtesy of: NOAA / NWS SPC

 

Observed sounding observations from Omaha, Nebraska this morning indicate a very unstable boundary, where measured CAPE (atmospheric instability) is around 2,300-2,400j/kg. Coincident with that, low-level southwesterly winds continue to surge moisture into the area before shifting clockwise into a more impressive unidirectional westerly wind at the mid-levels of the atmosphere. A temperature inversion also exists in the morning sounding but has eroded due to surface heating, but is indicative of a strong cap in place. Very cold air aloft will be supportive of supercells capable of producing very large, intense / destructive hail (e.g. baseballs). Additionally, the strong mid-level winds aloft will also increase the potential for widespread damaging wind events, and the 50-60mph effective-shear environment coupled with strong CAPE will be conducive for the development of a few tornadic supercells as indicated per morning sounding observations across the central Plains. Temperatures may to rise into the mid-upper 80s, coupled with dew points in the upper 60s / lower 70s and may favor widespread storm development in the afternoon. However, with the ongoing morning thunderstorm activity across the region, there could be a delay and[or] suppression of the thunderstorm vigor.

As per latest visible satellite imagery, widespread storm develop is already ongoing throughout the central Plains. Now whether or not these storms can dissipate and vaporize early enough, allowing for more volatile surface heating in the afternoon, will be a contributing factor on localized instability as well as surface temperatures. Regardless, the potential for widespread severe weather will exist throughout the central Plains / mid-upper Mississippi River Valley today. Within any severe storm, they will also have the potential to produce very heavy rains. Flash flooding could be very possible as well, on top of the other storm modes. I highly suggest that you have an action plan ready, in case your area is impacted by hazardous weather.

Remember to have your NOAA Weather Radios turned on today, as they relay instant hazardous weather information when it impacts your area. 

 

Multi-Day Severe Weather Outbreak Likely across central Plains

Another multi-day severe weather outbreak is expected across the north-central Great Plains Friday into Saturday. Hazards include intense supercells capable of producing extremely large hail, damaging gusts and isolated tornadoes.

day2probotlk_1730_any

Friday’s thunderstorm outlook zone via the NWS SPC.

 

Across the north-central Plains Friday, widespread development of supercells are likely across the region. Forecast parameters are indicative of storms firing along the dry line (dew point gradient anyone?). Initially, storms will be capable of producing very large hail where cold air aloft will support rapid coalescence within the stronger updrafts. Mid-level winds are modest, but not impressive, so the evolution of quasi-linear storms / storm mergers are likely before evolving into a Mesoscale Convective System (MCS). Low to mid-level relative humidity will support torrential downpours as well, so flash flooding is definitely something to watch out for further into Friday night as storm consolidations get underway. Clock-wise turning winds with height, isolated tornadoes are also possible… Although at this time, the tornado threat does not appear to be significant, but still keep an eye out for those tornado warnings (especially when the storms are isolated in the early afternoon).

As nightfall occurs, the spatial coverage will increase rapidly as the storms merge into an MCS. The severe threat will become more widespread in the evening and a transition to more widespread damaging winds and flooding will be of concern across the central Plains.

Saturday does not seem at this time to be as impressive as Friday’s set up, given probable ongoing widespread cloud debris hampering any strong surface heating. That said, however, if storms can develop and remain isolated, then the potential will indeed exists for high-based supercells at first capable of producing very large hail and damaging winds. If re-development can occur despite cloud cover, there could be once again storm mergers / quasi-linear formation in the later afternoon into the evening hours across the central / north-central Plains. The tornado threat also remains isolated, though cannot be ruled out.

Be sure to have your NOAA Weather Radios turned on Friday and Saturday, as well as listen to your local news / radio stations for weather information when severe weather impedes your area.

Severe Weather outbreak Likely across central Plains Saturday

Yet another major and widespread severe weather outbreak is likely across the central Plains tomorrow afternoon on June 14th.

day2

Severe Weather risk zone outlook for Saturday. Image courtesy of: College of DuPage

 

Conditions across the central Great Plains Saturday are expected to increase in volatility and become very moist. The strengthening of the low-level jet tonight, to 60-70 knots, will transport widespread moisture across the region. This will raise dew points across the area come Saturday morning into the afternoon. Forecast soundings are indicating that there will be a cap in place, so storm initiation at first will be held back until the cap can be broken… Which is very likely as the capping inversion erodes in the afternoon due to extreme instability. Current CAPE (atmospheric instability) is expected to be around 3,000-4,000j/kg Saturday afternoon across the central Plains, particularly along the Kansas / Nebraska border, which will be highly supportive of intense thunderstorm growth. Severe supercells are likely, of which they will be capable of producing extremely large hail, damaging winds and isolated tornadoes. Very cold air aloft is supportive of severe / destructive hail as well as the veering winds. Also, the strong wind fields from the low-levels shifting clockwise to the mid-levels will allow some perhaps widespread tornadic supercell potential at first, before becoming more of a widespread damaging wind event into the evening and night. Mid-level winds will allow updrafts to sustain themselves for long periods of time, so long-lived supercells are may occur.

With the high moisture content that will be present across the region, a few high-precipitation (HP) supercells could be possible which will result in a potential for flash flooding. With the potential for HP supercells, intense downdrafts or a wet-microburst or two cannot be ruled out in the heavier cores of rain. The relative unidirectional wind flow will also allot for storm mergers to occur after discrete cells initiate. That said, as storms congeal into a larger cluster, a few bow echoes or a squall line could be possible antecedent to the cold front that will be propagating east-northeastward relative to the mid-level winds.

With the extreme instability that will be in place along with the capping, clear skies may be present across the area. Please do NOT be fooled by clear skies. Whence the cap is broken, storms will grow explosively and become severe very quickly. It will feel very hot and moist outside, and the likelihood of widespread severe weather is very high. All storm modes are likely as aforementioned and again, as the day progresses into the evening a more widespread damaging wind threat will occur.

Above, I have two forecast soundings near the central Nebraska / Kansas border Saturday afternoon. As per the 1pm CDT sounding, there is a large capping inversion. Storm initiation likely will not start until later in the afternoon, around the 3-4pm CDT time frame perhaps as per the 4pm CDT sounding on Saturday suggests the capping erodes.

Now is the time to prepare and have an action plan ready. Be sure to stay tuned to your local media news or radio stations tomorrow, and to make sure your NOAA Weather Radio is charged and ready to go to receive hazardous warnings when severe weather strikes.

 

Significant Hail Threat across central Texas this afternoon.

The potential exists for widespread severe thunderstorms to develop this afternoon across central Texas with the threat of damaging winds, isolated tornadoes and extremely large hail.

Visible satellite image valid 3pm CDT. Image courtesy of: NOAA / NWS SPC

 

As per latest visible satellite imagery over the southern Plains, the leftover Mesoscale Convective System (MCS) continues to weaken over the ARK-LA-TEX region. Clear skies over central and western Texas has resulted in a rather robust rise in surface temperatures, where upper 80°F to lower 90°F surface temperatures coupled with dew points in the upper 60s and lower 70s. That said, the thermodynamic parameters across central Texas are becoming quite volatile and will support explosive growth of storms in the afternoon. Morning sounding observations from Dallas – Fort Worth indicated very unstable conditions, with CAPE (measure of atmospheric instability) near 3,500j/kg. Across central Texas, current CAPE delineates around 2,500-3,500j/kg which will support explosive storm development as aforementioned. Isolated tornadoes and damaging winds are possible, and supercells will also have the potential to produce giant hail given the extreme instability and thermodynamic parameters. Main storm mode and concern will be severe / damaging hail over a widespread region, including Dallas – Fort Worth, Austin and San Antonio. Storms may later consolidate and merge back into a Mesoscale Convective System, posing a widespread hazard for damaging winds later in the evening.

Given the forecast of relatively high cloud base heights, the environment is becoming highly supportive of supercells mainly producing significant hail. However as aforementioned, storm consolidations are likely and the significant hail risk will eventually subside later into the night. Again, the severe wind hazard will also increase into the evening.

Be sure that you tune into your local media / radio stations and have your NOAA Weather Radio turned on to receive hazardous weather information for your area. Don’t be scared, be prepared.

 

 

 

 

Severe Weather threat Today in central Appalachia, Great Plains.

Severe Weather continues through the U.S. today, with widespread hazards across central Appalachia and out west into the Great Plains.

2-km visible satellite valid 2:30pm EDT. Image credit: College of DuPage

 

Widespread severe weather is likely across the North Carolina Piedmont into the central Appalachians this afternoon. Morning sounding observations across the region have indicated a very moist boundary layer, with warming of surface temperatures due to clearing of skies evident on the visible satellite. With the clear skies, instability is expected to increase across the region which will be perpetrator in the evolution of widespread severe thunderstorms. That said, upon storm initiation cells may be discrete therefore may have the potential to become supercells, posing a risk for isolated tornadoes along with severe hail / wind. Modest wind shear across the region around 30-40 knots, with an observed sounding from Washington D.C. showing a clockwise shift in winds with height and forecasted CAPE values around 1,000-2,000j/kg this afternoon, rotating thunderstorms cannot be ruled out. Given the onset of an extremely moist boundary layer, as indicated on observed soundings, severe storms will also have the potential to produce torrential downpours. Flash flooding is very possible.

…Further west into the Great Plains…

Potential exists this afternoon for widespread severe thunderstorms, of which storms will be capable of producing very large hail and damaging winds. Supercell initiation may likely be discrete along the dry line in western Kansas down into western Texas, but as more storms fire across the Plains overall spatial coverage is expected to widen. With that, storm mergers are likely as the afternoon progresses. Toward evening and night time, it appears that the evolution of a Mesoscale Convective System (MCS) is likely to form. Observed sounding analysis show a relatively modest wind field from the low to mid-levels. This will support widespread thunderstorm growth and eventual MCS evolution as mid-level winds will be able to ventilate stronger thunderstorm updrafts. As storm mergers occur, the severe / damaging wind threat will increase exponentially over the central Plains, particularly around the Kansas and Oklahoma borders.

Latest water vapor imagery overlays shows strong flow across the central Plains. As storms fire this afternoon and consolidate into a Mesoscale Convective System, it will likely produce severe wind and heavy rain across a large area. Widespread wind damage could be associated with this system.
