ISSUED AT 308 PM CDT WED APR 29 2026
THIS AFTERNOON A FRONTAL BOUNDARY EXTENDED FROM WRN PA SWWD TO NW
AL AND BACK TOWARD TX. ALONG AND AHEAD OF THIS BOUNDARY,
CONVECTION IS ALREADY DEVELOPING OVER MS. THIS CONVECTION WILL
SPREAD EWD ACROSS C AL THIS AFTERNOON INTO THU. THERE IS EXPECTED
TO BE SUFFICIENT FORCING AND INSTABILITY FOR STRONG TO MARGINALLY
SEVERE STORMS TO DEVELOP THROUGH THIS EVENING AHEAD OF IT.
DAMAGING WINDS AND LARGE HAIL WILL BE THE MAIN THREAT. NRLY FLOW
WILL HELP TO GIVE US A RAIN BREAK BEHIND THE FRONT FOR THU
AFTERNOON AND EVENING. AN UPPER SHORTWAVE WILL ALLOW FOR RAIN
CHANCES TO RETURN FOR FRI AND SAT. HOWEVER, TEMPERATURES AND DEW
POINTS WILL BE MUCH LOWER BEHIND THE FRONT AS THIS WAVE MOVES
THROUGH. LOOK FOR MAINLY RAIN SHOWERS WITH LOW PROBABILITY OF
THUNDERSTORMS WITH THE ACTIVITY FOR FRI AND SAT.
DRY WEATHER RETURNS ON SUN BEHIND THE UPPER SYSTEM WITH A LARGE
SURFACE RIDGE EXTENDING FROM TX, ACROSS THE DEEP SOUTH AND INTO
THE CAROLINAS. COOL AND PLEASANT SPRING CONDITIONS ARE EXPECTED.
RAIN-FREE WEATHER WILL CONTINUE UNDER THE INFLUENCE OF RIDGING
THROUGH THE END OF OUR EXTENDED FORECAST ON TUE. LOOK FOR A
WARMING TREND AS WE MOVE INTO MON AND TUE ACROSS AL AS OUR AIRMASS
MODERATES AND THE SURFACE RIDGE WEAKENS.
