Severe weather season should be in high gear this time of the year with a significant increase in the number of tornadoes reported in the United States starting in April. Not only has it been a slow month for tornadoes, it's been an extremely slow year. In fact, Greg Carbin, Warning Coordination Meteorologist at the Storm Prediction Center in Oklahoma City, says that 2014 has the lowest number of tornadoes on record through April 21st with only 20 reports.
On average, the U.S. will experience more than 100 tornadoes from January through mid-April. Another bright note on the quiet severe season, so far there have been no tornado-related deaths reported in the country. A cooler spring in the eastern U.S. and the jet stream pattern have suppressed storm development in the plains where most of the tornadoes hit this time of the year.
In the D.C. region, we have seen one twister so far in 2014. A rare February tornado tracked from Compton, Md. to Cove Point, Md. on the 21st. It was an EF0 tornado on the Enhance Fujita Scale with maximum winds of 80mph, and it did cause some structural damage. Typically, our area peaks with tornado activity and severe storms in June and July.
Atmospheric conditions will be changing this weekend as a potent storm moves out of the Rockies and into the Plains and that could rock our quiet spring.
A significant outbreak of severe weather will be possible Saturday through Monday.
As of this writing, while we do expect to get some rain from that system next week, severe storms are not anticipated in the Mid-Atlantic.
