Wednesday has the potential to be a very destructive weather day in the Southeast and in parts of Alabama. We have the key ingredients coming together for a significant severe weather day. The instability is incredibly high as well as the wind shear. A common question I receive is what about my town? That is a difficult question to answer because we can't really pinpoint where a tornado will form. It is safe to say areawide tomorrow the severe weather threat is high. The tornado parameters are a big higher east of I-65 which is usually not the case.
What can we expect? There will be several rounds of severe weather. The first potential round will come during the morning hours and mainly impact areas south of I-20. This round has a lower threat for tornadoes, but still worth watching. These storms could arrive as early as 4am. Round #2 will arrive between 11am and 1pm. These storms will have a greater coverage east of I-65. Supercell thunderstorms are possible.
What type(s) of severe weather? Long-track tornadoes are possible producing EF3+ damage, damaging winds over 60-70mph, and large hail.
Call to Action: Make sure you have several ways to receive severe weather information including our First Alert weather app and NOAA weather radio, let family and friends know severe weather is likely Wednesday, make sure your mobile devices are charged, and have a helmet for you and your children.
Remember this is a changing and evolving forecast and the threat areas may change. We could see this situation improve or worsen. Meteorologically, this is one of the more impressive severe weather setups I've seen here in years. You should not take it lightly.
We'll keep you updated!
