Some Stronger Storms Friday?
Late-evening model guidance from the NAM (North American Mesoscale model) suggests that Isaac’s remnant circulation over Arkansas on Friday could lend a little strength to some of the pop-up storms on Friday.
Tropical rain bands can create spin-up tornadoes over 300 miles away from the storm’s central circulation. A few tornado warnings were issued on rotating thunderstorms between Marianna, Florida and Ozark, Alabama this evening over 340 miles from the center of Isaac, but no damage was reported.
Here’s video of a tornado that hit Gulfport, Mississippi earlier this evening (WARNING: THERE IS FOUL LANGUAGE IN THIS VIDEO. TURN DOWN YOUR SPEAKERS!)
What All This Means To You:
- Any storms that develop on Friday, especially west of I-65, will need to be monitored carefully.
- This is a very small risk of severe weather. It’s only worth mentioning because we don’t want you to be caught completely off guard if a severe storm or two does develop.
- The main timeframe here for the small risk of a strong or severe storm will come from about 9 AM to 6 PM.
- We do not expect this to impact any high school football games on Friday night at this time.
- Go about your business-as-usual on Friday. Have a way to keep in touch just in case that small chance of severe weather materializes. We offer a number of mobile applications at WHNT.com to keep you informed (including Live Alert 19 and Baron Saf-T-Net).
We will keep you updated on this! Don’t sweat it just yet; this is just a heads-up! Often, tornadoes that develop in tropical rain bands are small and short-lived, so again, we do not expect this to be a widespread problem. It’s only a small chance.
