Severe Storms Possible Tonight/Tomorrow

QUIET AFTERNOON: As expected, the weather is quiet across Alabama this afternoon with little showing up on radar. Temperatures are near 90 degrees, and the sky is partly sunny. We note the air is becoming very unstable; surface based CAPE values are now at 6,000 j/kg just northwest of Muscle Shoals. This is “priming the pump” for the severe weather potential tonight.

SEVERE WEATHER THREAT TONIGHT: SPC maintains an enhanced risk (level 3/5) of severe storms for parts of Northwest Alabama, with the standard “slight risk” (level 2/5) down to Demopolis, Prattville, and Roanoke. There is a marginal risk of severe storms as far south as Evergreen and Troy.

Here are the key points for tonight…

*The primary threat will come from damaging straight line winds, but an isolated tornado is possible.

*There is a chance this could bring widespread wind damage, similar to the June 28 derecho event.

*Highest chance of wind damage will be along and west of I-65, but no doubt we could see severe storms over East Alabama as well.

*Not everyone will see a thunderstorm tonight.

*Be sure you can hear warnings, and pay attention to severe thunderstorm warnings.

TOMORROW: We should be in a relative lull tomorrow morning and early tomorrow afternoon, but additional storms will form late tomorrow afternoon and tomorrow night. Those could be strong to severe as well, and SPC has expanded the “slight risk” (level 2/5) to include much of Alabama for this potential.

The main threat with the storms late tomorrow and tomorrow night will come from strong straight line winds, but an isolated tornado is possible. These storms will rather scattered in nature, and some will see no rain at all. Main threat of heavier storms will come from 5:00 p.m. until 12:00 midnight. Otherwise, tomorrow will be partly sunny with a high in the low 90s.

SUNDAY: There is a marginal risk (level 1/5) for Southeast Alabama… including places like Dothan and Geneva. Elsewhere, we are forecasting a mix of sun and clouds with a few scattered, mostly afternoon and evening showers and thunderstorms. Sunday’s high will be in the upper 80s.

NEXT WEEK: There will be sufficient moisture and instability for scattered, mostly afternoon and evening showers and storms each day Monday through Friday, otherwise partly sunny days with high mostly in the upper 80s, below average for late July. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: All remains quiet across the Atlantic basin and tropical storm formation is not expected through early next week.
