FIRST ALERT: Severe threat possible, especially west of I-65 Tuesday night
BIRMINGHAM, Ala. (WBRC) - All is cool & quiet across Alabama tonight with a clear sky on First Alert AccuTrack. Skies will stay mostly clear overnight with temperatures falling into the 40s again for Tuesday morning. Tomorrow will start off dry with even some sunshine around, but clouds will increase in coverage later in the day ahead of our Next Big Thing, a potent storm system moving across the Deep South.
Widely scattered showers and storms will begin to fire up across central Alabama late tomorrow afternoon by 4-5 p.m. . Areas along and west of I-65 in Alabama are under a Level 2 out of 5 risk with areas east of I-65 under a Level 1 out of 5 risk through early Wednesday morning. Likely the more potent storms in our area will be west of I-65 and closer to the I-20 corridor in west Alabama. The greater risk for severe weather should remain over Mississippi, where ingredients are more favorable to produce damaging severe weather. Our severe risk is lower in comparison, but we still can’t rule out at least a few storms tomorrow night into early Wednesday morning that could bring strong wind gusts, large hail, and isolated tornadoes, especially areas south and west of Birmingham. This system will also bring a good 1-2″ inches of rain with locally higher amounts possible. Remember, even if you don’t see a severe storm pop-up where you live, heavy rain and lightning will make for some booming thunderstorms overnight. Storms will weaken as they move east overnight, eventually clearing our southeast counties by 8 a.m. Wednesday.
A cold front associated with this storm system will bring another shot of cold, dry air briefly back into Alabama. The warmest part of the day on Wednesday will likely be early in the morning with temperatures in the 60s and falling into the 50s by the afternoon as the cold front passes through. Winds will also shift to out of the north and stay breezy with gusts up to 25 MPH possible during the afternoon. So, prepare to dress warmly on Wednesday! Sun will break through during the afternoon, and skies will turn clear by Wednesday night. We have a First Alert for freezing temperatures again by Thursday morning and highs will only rebound into the mid 50s by the afternoon. Thursday is also the first day of December and the start of meteorological winter! So, kicking-off the season and new month with #WinterVibes. The cooldown will be short-lived though!
The remainder of the week looks to feature a more unsettled and eventually warmer weather pattern as a ridge of high pressure builds over the Gulf. A series of disturbances moving through north of the ridge though will allow at least a few showers across north Alabama beginning Friday and into next week. For now, we just have stray showers possible on Friday, but a 20-30% chance of rain over the weekend and into early next week. Saturday looks to have the most favorable rain coverage, but no day will be a washout. So, if you need to get some decorating or shopping done this weekend, keep up to date with any chance of rain around on the WBRC First Alert Weather App. Temperatures will still be chilly on Friday morning in the upper 30s and low 40s, but lows will rebound into the 50s by the weekend. Highs will climb from the low 60s on Friday to upper 60s and low 70s in the coming days.
