A slow moving disturbance continues to produce moderate to heavy rain across west Alabama on Friday morning and light rain to the east.
Rainfall estimates so far range from .50" to almost 1" across parts of Marion, Lamar, Fayette and Winston counties. Amounts drop off considerably to the east across the part of the state that's suffering the most from a rainfall deficit.
Anniston has seen only .09" so far this month and is running -2.47" below normal. Birmingham has a monthly rainfall deficit of -1.98", Tuscaloosa of -2.01" and the Shelby County Airport of -2.44".
Computer models continue to indicate the heaviest rain exceeding 1 inch to fall across west Alabama and much lighter amounts to the east of I-65 through the rest of Friday.
As this system continues to shift eastward with time, so will the better rain chances. Total rainfall amounts by the end of Saturday may approach the 1 inch for areas to the east of I-65.
We will be keeping a close eye on the radar later Friday afternoon and early evening for possible severe storms across west Alabama. The greatest risk for severe weather is the area highlighted in yellow which includes Greene, Sumter, and Hale counties and points southward. Areas just to the north of the highlighted slight risk zone needs to still be on guard and have a way to get weather warnings later today just in case a storm ramps up to severe level. Severe threats include isolated tornadoes and damaging straight line wind gusts.
If you have plans on heading to the Gulf Coast, I recommend leaving as early as possible today because short term models indicate strong storms marching eastward across south Alabama after 7PM.
Rain and storms are likely Friday and lingering through Friday night. This system is tracking eastward and the general shower and storm motion will be east or northeasterly. Short term models indicate west Alabama getting more of a break from the wet weather this weekend and better rain chances focusing across the eastern part of the state.
The hour-by-hour futurecast shows the wet periods and best chance zones for rain through the weekend. Overall, it looks like the wettest day is Friday, especially to the west of I-65.
