FIRST ALERT: First Alert Weather Day in effect for Tuesday--your updated forecast on WAFF 48 News Today

(WAFF) - First Alert Weather Day

A dense fog advisory is in effect this morning, and visibility could be reduced to less than a quarter-mile in spots.  By noon, a wind advisory goes into effect ahead of the line of storms. ?

Our severe threat materializes later this afternoon. The first round will be in the form of individual or discrete thunderstorms developing after 2-3 p.m. These storms would be isolated in nature, but would become more intense than the squall line expected later this evening if they do form.

The second round of strong-to-severe storms shifts in this evening in the form of a squall line. The squall line should shift into northwestern AL around 6-8 p.m. and track east with time. The line shifts into the Huntsville Metro area by 9 p.m.-12 a.m. and should move through northeastern AL after 10 p.m. This line would be capable of producing wind gusts up to 60-65 mph as well as a brief, spin-up tornado. Flash flooding also becomes a concern due to prolonged heavy rain. Some areas will pick up 3-4" of rain overnight. The storm threat should be over area-wide by 3 a.m. with the threat ending sooner than that farther west. Rain showers taper off Wednesday morning, and clouds should diminish into the afternoon.
