A slow-moving and powerful storm system has brought day after day of severe weather across the Mississippi Valley and Deep South this week with numerous tornadoes reported that have caused widespread damage and several casualties.
Over the past two days, the Storm Prediction Center has received over 100 preliminary tornado reports across Iowa, Missouri, Arkansas, Louisiana, Mississippi, Tennessee, Alabama, and Georgia. Some of the tornadoes have been extremely large and long-track twisters. Heavy damage has been reported in many communities across these states and National Weather Service officials will now go through the tedious process of evaluating the damage and providing estimates of the strength of these tornadoes.
The forecast was in place well in advance of this storm system, calling for several days of severe weather with strong tornadoes possible. Unfortunately, it was very well done and advanced notice was there.
Powerful jet stream winds combined with a warm, moist, and extremely unstable air mass has created a prime atmosphere for producing discrete supercells capable of producing very large hail, damaging winds, and tornadoes. In addition to the severe weather, the slow-moving nature of the storms has caused widespread flash flooding with many areas reporting several inches of rainfall.
