DISCUSSION
ISSUED AT 405 AM CDT SUN MAY 24 2026
THE WET WEATHER PATTERN WILL CONTINUE ACROSS OUR REGION THROUGH
THE WEEK AHEAD. THIS MORNING IS A PERFECT EXAMPLE OF WHAT WE WILL
CONTINUE TO SEE NEARBY. WITH ABUNDANT TROPICAL MOISTURE IN PLACE
(PWAT VALUES OF 1.5-2.0 INCHES) AND UPPER-LEVEL TROUGHING
AFFECTING THE REGION, ONE REMNANT MCV FROM YESTERDAY'S CONVECTION
HAS DECAYED AND DRIFTED INTO NORTH MISSISSIPPI WHILE A SECOND MCV
DEVELOPED FROM OVERNIGHT CONVECTION ALONG THE GULF COAST AND IS
SPINNING NOTICEABLY IN REGIONAL SATELLITE AND RADAR IMAGERY OVER
SOUTHEAST LOUISIANA. THIS SECOND SYSTEM WILL STEER NORTHEAST
ACROSS SOUTHEAST MISSISSIPPI AND CENTRAL ALABAMA TODAY, BUT THE
PATTERN COULD SEE OTHER CONVECTION DEVELOP AND ORGANIZE IN A
SIMILAR FASHION OVER THE NEXT SEVERAL DAYS. AN APPRECIABLE CHANGE
TO THE FORECAST REALLY WON'T BE FELT UNTIL JUST AFTER THE CURRENT
7-DAY FORECAST PERIOD. EARLY NEXT WEEK, THE PATTERN MAY SHIFT
ENOUGH TO ALLOW A COLD FRONT TO PUSH SOUTH (WITH DRIER AIR)
TOWARD OUR REGION. /NF/
