DISCUSSION
(THIS AFTERNOON THROUGH SUNDAY)
ISSUED AT 1240 PM CDT MON APR 20 2026
FAIR WEATHER IS EXPECTED OVER THE NEXT FEW DAYS AS A 500 MB RIDGE
AXIS APPROACHES FROM THE CENTRAL U.S. JUST AHEAD OF IT, A
SHORTWAVE TROUGH IS SHOWN TO SKIRT ACROSS THE GULF COAST WITH JUST
ENOUGH MOISTURE TO BRING AN INCREASE IN MID- TO HIGH-LEVEL
CLOUDINESS TO CENTRAL ALABAMA FROM MID TUESDAY INTO WEDNESDAY.
THE SUB-TROPICAL JET STREAM IS FORECAST TO BECOME MORE ACTIVE
ACROSS OUR AREA FROM SATURDAY INTO NEXT WEEK, OFFERING PERIODIC
SHOWERS AND THUNDERSTORMS. THE PATTERN SHOULD FAVOR DEW POINTS
RISING INTO AT LEAST THE LOW 60S, YIELDING WEAK TO PERHAPS MODERATE
INSTABILITY + BOUTS OF INCREASED/VEERING FLOW ALOFT PER GFS/ECMWF
ENSEMBLES. CURRENTLY, THE PRIMARY SIGNAL FOR SEVERE THUNDERSTORMS
IS TO OUR WEST; HOWEVER, SLIGHT CHANGES TO THE MID/UPPER LEVEL
CONFIGURATION AND STORM TRACK COULD INVOLVE OUR AREA IN SOME
FASHION AT SOME POINT. THIS IS JUST SOMETHING TO MONITOR. IN THE
LEAST, WE'LL HAVE A FEW OPPORTUNITIES FOR MUCH- NEEDED RAIN.
