(TODAY)
ISSUED AT 306 AM CDT THU APR 30 2026
AN OUTFLOW BOUNDARY YESTERDAY EVENING PUSHED NORTHWARD INTO N AL
PROVIDING AN AREA OF LIFT THAT RESULTED IN SHOWERS AND
THUNDERSTORMS. THESE HAVE NOW PUSHED NORTHEAST INTO GA. WHILE
THE COLD FRONT HAS PUSHED SOUTH OF THE LOCAL FORECAST AREA,
LINGERING SHOWERS CONTINUE TO MOVE EASTWARD THIS MORNING.
HOWEVER, AS AN UPPER LEVEL JET STREAK SHIFTS OVERHEAD, THE
FORECAST AREA BECOMES SITUATED UNDER THE RIGHT EXIT REGION, AN
UNFAVORABLE AREA FOR PRECIP. SATELLITE IMAGERY SHOWS THIS WITH AN
AREA OF CLEARING ACROSS WESTERN TN. THIS AREA OF SUBSIDENCE IS
HELPING PUSH THE SHOWERS FURTHER TO THE SOUTH AND EAST.
FOR TODAY, A COOLER AND DRIER AIRMASS WILL FILTER IN FROM THE
NORTH. WITH THE UPPER LEVEL PATTERN MORE ZONAL, THE CLOUD COVER
SHOULD REMAIN THROUGH THE DAY KEEPING AFTERNOON HIGHS ONLY IN THE
UPPER 60S TO LOWER 70S.

EASTWARD ALONG THE NORTHERN GULF COAST. WOULD EXPECT MOSTLY DRY
CONDITIONS THROUGH THE AFTERNOON ON FRIDAY, BUT CLOUDS WILL LIMIT

AFOREMENTIONED STORM SYSTEM WILL CLIP THE TENNESSEE VALLEY FRIDAY
NIGHT, BRINGING MEDIUM TO HIGH (50-80%) CHANCES FOR SHOWERS AND A
FEW THUNDERSTORMS (CAPABLE OF PRODUCING SOME WETTING RAINS OF

HIGHS BACK INTO THE LOW TO MID 60S ON SUNDAY AND OVERNIGHT LOWS
INTO THE LOWER 40S SUNDAY NIGHT. THE UPPER-RIDGE AXIS WILL BUILD
EASTWARD INTO THE AREA EARLY NEXT WEEK, AS A PRONOUNCED WARMING
