RADAR CHECK: Most of Alabama is rain-free this afternoon…. with a mix of sun and clouds temperatures are around the 80 degree mark. The average high for April 12 in Birmingham is 74. Tonight will be mostly cloudy with a few isolated showers.
We don’t expect much change during the day tomorrow… highs around 80, some sun, and only isolated showers during the day. But, a line of strong to severe thunderstorms will likely move into the state late tomorrow night into the early morning hours Thursday. SPC maintains an “enhanced risk” (level 3/5) for the northwest corner of the state; a “slight risk” (level 2/5) is up for much of North, Central, and Southwest Alabama… and most of Southeast Alabama is under a “marginal risk” (level 1/5).
While a few storms could creep into Northwest Alabama as early as 8-9 p.m.. the main line should enter the northwest corner of the state around 11:00 p.m.. it will reach I-59 (Tuscaloosa/Birmingham/Gadsden) around 4-5 a.m… and then moving into East and Southeast Alabama after 6:00 a.m. The storms should weaken after 3:00 a.m. as instability decreases and dynamic support fades.
The main threat will come from strong, gusty winds ahead of the line, but an isolated tornado can’t be totally ruled out, especially over the northwest counties of the state. With this being a “middle of the night” event, but sure you have you NOAA Weather Radio on, and don’t use the “do not disturb” feature on your phone so you can get notifications.
The sky will become partly to mostly sunny by Thursday afternoon as dry air returns… the high will be in the mid 70s. Friday will be dry and mild for most of Alabama as well, but a few showers are possible over the southwest counties around Mobile.
EASTER WEEKEND: A surface front will move up into the state from the south, and meander around the area over the weekend, setting the stage for unsettled weather. The sky will be cloudy Saturday and Sunday with occasional showers likely both days. Some thunder is possible, but severe storms are not expected. Highs will be in the 70s.
NEXT WEEK: Showers remain likely Monday, but dry air returns Tuesday and Wednesday. Global models show another round of rain and possible thunderstorms Thursday… See the Weather Xtreme video for maps, graphics, and more details.
