Where Are The Tornadoes?

imagesLast month was one of the quietest months for tornadoes in 44 years.   So far this year, there are half the tornadoes that there were at this time in 2012.  Why is this the case?

Livescience.com reports that the main reason is that spring has been colder than average for much of the nation’s mid-section.  Warm air over Greenland and the North Atlantic has blocked the normal flow of air from west to east and south to north.

With winds from the north, the eastern two-thirds of the United States have been socked in with Arctic air.  Tornadoes are fueled by warm and muggy air.

The pattern appears to be changing with a chance of strong storms in the southern Plains states early next week.
