This is the most significant severe weather threat we've had in a long time. The Storm Prediction Center has shifted the moderate risk farther eastward and now includes the Shoals.
Models are still indicating the primary risk will be damaging winds in excess of 60mph. There is also a lower risk for tornadoes, but this could change depending on how much instability is realized ahead of the front. Right now, the atmosphere is capped and that will prevent supercells from forming ahead of the main line. Still - we will have enough forcing to result in a few tornadoes within the mainline. I fully anticipate a tornado watch overnight through tomorrow morning.
We should brace for severe storms as early as 3am in West Alabama and hitting the I-65 corridor as early as 7am. Storms should weaken just a bit as they move into our East Alabama Counties due to lower instability. I anticipate the severe threat to be over by noon.
What to Expect: We will likely have power outages with this system due to the high winds. It's possible a few tornadoes could develop. However, the winds from the thunderstorms may be stronger than what you see with smaller tornadoes.
Call to Action: Have your weather radio turned on and ready tonight. If you don't have a NOAA weather radio, make sure you have a reliable way to receive warnings. Sirens are not good enough! Make sure you have a portable radio and a flashlight.
I would also suggest you secure any loose items around your home. You don't want that patio umbrella ending up across the street.
We will keep you updated on-air and online during this severe weather event.
