At 6:05 am, we are already starting to see showers and thunderstorms moving across the Tennessee Valley this morning, with intense rainfall and plenty of lightning over portions of Franklin and Lawrence counties. These are moving to the east-northeast at roughly 35 MPH and will be affecting Decatur and Moulton within the next few minutes. There is another band of showers stretching from roughly Hoover to the southeast to roughly around Auburn, but nothing too impressive with these.
A Slight Risk for severe storms is up for all of North Alabama and includes the northern parts of Central Alabama down to a line from near Macedonia (Pickens Co.) to Tarrant (Jefferson Co.) to near Fruithurst (Cleburne Co.). A Marginal Risk is up for locations south of that to a line from just north of Livingston (Sumter Co.) to Clanton (Chilton Co.) to just south of Five Points (Chambers Co.).
This is the combined Hazardous Weather Outlook from Birmingham and Huntsville NWS offices showing the threats for today. For North Alabama and down into the northern counties of Central Alabama, the main threats will be from damaging wind gusts up to 60 MPH, hail up to one inch in diameter (quarter size), and maybe a brief tornado or two. For the rest of the northern half of Central Alabama, the threats will be from isolated damaging wind gusts up to 60 MPH and hail up to one inch in diameter.
There is the potential for stronger to severe storms this morning over North Alabama and maybe just into the extreme northern parts of the northern-most counties in Central Alabama from now through roughly 10:00 am as a warm front will be moving northward across those locations. All of the threats will be possible with these storms as they move through.
There will be a second round of stronger to severe storms that will begin to move into the northwestern parts of the area starting roughly around 3:00 pm and those will move through the western parts (along and west of a line from Huntsville to Tuscaloosa) from 3:00 pm to roughly 8:00 pm, and the eastern parts from roughly 7:00 pm to just before midnight.
