A severe thunderstorm threat that will span multiple days has begun in some areas of the South and Midwest, and will spread to the East on Friday.
Dangerous storms are a certainty, but this current severe weather threat is a little different than the deadly outbreak of last weekend.
Thursday’s thunderstorms are tracking eastward
Damaging winds, hail and tornadoes tracked eastward throughout areas of the South and Ohio Valley on Thursday. Strong to severe storms might also continue into Friday morning as they head towards the East Coast.
Parts of Alabama and Mississippi were under a tornado watch throughout most of Thursday.
Flash flooding is a major threat
A widespread region of one to three inches of rainfall stretches from eastern Texas into the Southeast, Ohio Valley, mid-Atlantic and Northeast. Local, heavy rainfall came down in some areas.
Parts of eastern Texas, northern Louisiana and southern Arkansas were hit with flash flooding last weekend, and the rainfall late this week threatens to cause additional flash flooding in these areas.
The National Weather Service has issued a flash flood watch for northeastern Texas and eastward into Mississippi, as well as southern Illinois and central Indiana.
Temperatures in flux
As is often the case with Spring weather, there is a battle between warm and cold temperatures that continues for the rest of this week.
Ahead of the low-pressure system, warm temperatures will spike. High and low temps will be roughly 10 to 25 degrees above the average for mid-April. Highs will be in the 70s for parts of the Midwest and Northeast, and in the 80s in the South.
Behind the cold front, temperatures are expected to drop back to the average, or possibly below average. The coolest temperatures as compared to the average will happen in parts of the South and Ohio Valley.
In the Midwest, highs will peak in the 40s and 50s. There will be morning lows in the 40s that will reach all the way to the Florida Panhandle over the weekend.
