James Spann forecasts strong storms for Alabama Wednesday night, Thursday morning from the Alabama NewsCenter on Vimeo.

RADAR CHECK: Rain is fairly widespread over the northern half of Alabama this morning ahead of a surface front that will stall north of here today. The rain will ease off this afternoon and we expect generally dry conditions with only isolated showers this afternoon and tonight.

Wednesday will be mostly cloudy and mild with only a few scattered showers; Temperatures will reach the low 70s by the afternoon.

STRONG STORM POTENTIAL: A series of severe thunderstorms are expected to move through Alabama late Wednesday evening and early Thursday morning. The Storm Prediction Center has put areas north and west of Birmingham at low risk (level 1 of 5) of severe storms through 6am Thursday, and put areas south and east of Birmingham at low risk after 6am

The line of strong storms will pass through from about 1 a.m. to 9 a.m. Thursday. There will be very little surface-based instability, and the main threat will come from strong wind gusts. The atmosphere is highly sheared, so a short, isolated tornado cannot be completely ruled out, but is not likely. Overall, the risk of severe weather from this event is low.

Rain levels will be about half an inch for most communities as the line is swept through quickly and skies will clear Thursday afternoon as drier air returns. Temperatures remain mild, with highs between 67 and 72 degrees.

FRIDAY AND WEEKEND: Friday will be dry and cool with plenty of sunshine and seasonal temperatures – highs in the 50s after the day started in the 30s. Clouds are increasing on Friday night and we will be dealing with more rain over the weekend. Rain, beginning initially over southern Alabama Saturday morning, will spread north, and rain is likely to fall statewide late Saturday, Saturday night and well into Sunday. There will be no surface-based instability, meaning no risk of severe storms and likely very little thunder. Weekend rainfall amounts are about 1 inch, with scattered heavier amounts.

NEXT WEEK: Monday will be dry but another producer of rain arrives Tuesday night into Wednesday. At the moment it looks like rain with no risk of severe storms.
