Alabama Update Just After 1 p.m.

Showers and thunderstorms have developed early this afternoon across West Central Alabama from Pickens, Greene, Sumter, and Hale Counties southward into the Mobile area in the vicinity of an upper level trough that extends back into Mississippi. Other storms are over extreme Southeast Alabama.
Storms are also firing across the southeastern half of Mississippi as well. But the threat of flash flooding is increasing in the areas that are currently seeing storms as they are producing torrential rainfall and flash flooding thresholds are relatively low. It will only take about 2: of rain in an hour to cause flooding.

As far as severe weather goes right now, the primary concern is over eastern Arkansas, southwestern Tennessee, northeastern Louisiana, and northwest Mississippi where convection is firing north of Memphis over to Jackson and along the leading edge of an old overnight MCS. The SPC says there is a 60 % chance of a severe thunderstorm watch being issued for the aforementioned region. The airmass over Mississippi is unstable and weakly sheared, so the main threat will be damaging winds from downbursts. Refer to the graphic for the SPC discussion.

You can see the precipitation and the cloud cover across the South. Temperatures across Alabama at this hour range from 80 at Haleyville to 88 at Montgomery and Demopolis.

The complex of storms will push into Alabama later this after and will continue to be accompanied by a severe weather threat. Nearly every square inch of the state is in an SPC Slight Risk for today and tonight. It appears it may come in two rounds this evening, one arriving around 4-7 p.m in West Alabama and another after 10 p.m. It could be a stormy night across North and Central Alabama.

Stay alert to changing weather conditions and keep one ear out for future updates.
