The SPC has issued a mesoscale discussion which is in line with my update from a few minutes ago.
They do mention that they will likely issue a severe thunderstorm watch for much of West Alabama later.
These is a pretty good potential for damaging winds this afternoon with the strong storms that will be pushing southeast from Mississippi, especially south of the boundary that is being created by the southward moving mesoscale convective system pushing southward across North and East Alabama at this time.
Gusty winds and a brief shower just occurred at our location in Trussville.

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
568…569…CONTINUES.
A NEW WW WILL LIKELY BE REQUIRED LATER TODAY ACROSS THE LOWER MS
VALLEY EWD INTO PORTIONS OF AL. DAMAGING WINDS WILL BE THE PRIMARY
THREAT.
A SUBSTANTIAL COLD POOL CONTINUES TO TRAVEL QUICKLY SWD ACROSS THE
MS VALLEY…WITH STRONG CONVECTION ALONG THE LEADING EDGE. OTHER
CONVECTION OVER NRN AL WAS SENDING ANOTHER BOUNDARY SWWD…WHICH MAY
CONVERGE WITH THE WRN OUTFLOW LATER TODAY.
THE NRN END OF THE WRN LINE WILL CONTINUE EWD INTO MIDDLE TN AND NRN
AL. RADAR TRENDS SHOW A LARGE AREA OF OVERTURNING IS OCCURRING
WHICH…COMBINED WITH PREVIOUS COOL OUTFLOW…WILL TEMPER SEVERE
WIND POTENTIAL SOMEWHAT WITH THIS ACTIVITY.
OTHERWISE…WITH HOURS OF STRONG HEATING AND HIGH PRECIPITABLE WATER
IN PLACE S OF THE OUTFLOWS…STORMS SHOULD REGENERATE AND
STRENGTHEN. RELATIVELY STEEP MID LEVEL LAPSE RATES IN PLACE AND
FAVORABLE TIME OF DAY SHOULD YIELD RATHER STRONG UPDRAFTS WITH
SUBSTANTIAL WATER LOADING AND DOWNDRAFT POTENTIAL…DESPITE WEAK
WIND PROFILES.
