DISCUSSION
(THIS AFTERNOON THROUGH MONDAY)
ISSUED AT 1258 PM CDT TUE JUN 23 2026
CURRENT SURFACE OBS INDICATE THE FRONTAL BOUNDARY IS STALLED TO
OUR SOUTH ALONG THE GULF COAST. DEWPOINTS RANGE FROM THE MID 60S
NORTH TO LOWER 70S SOUTH, AND HUMIDITY IS SLIGHTLY LOWER TODAY
THAN IT HAS BEEN RECENTLY. BROAD RIDGING OVER THE DESERT
SOUTHWEST AND PERSISTENT CYCLONIC FLOW OVER THE GREAT LAKES AND
MIDWEST REGIONS WILL INFLUENCE NORTHWESTERLY FLOW ACROSS CENTRAL
ALABAMA. AN EMBEDDED SHORTWAVE TROUGH WILL SPARK CONVECTION FROM
OKLAHOMA THROUGH ARKANSAS TONIGHT. THIS FORCING WILL SHIFT
EASTWARD BY TOMORROW AND ADDITIONAL THUNDERSTORM ACTIVITY IS
EXPECTED TO PROGRESS INTO MISSISSIPPI TOMORROW MORNING. POPS WERE
RAISED GIVEN THE MEDIUM CONFIDENCE IN THE ARRIVAL OF A DECAYING
MCS OR ADDITIONAL THUNDERSTORM DEVELOPMENT IN SOUTHWESTERN
PORTIONS OF OUR AREA TOMORROW AFTERNOON. THIS ACTIVITY IS
EXPECTED TO DIMINISH AS IT MOVES EASTWARD INTO THE EVENING HOURS,
POTENTIALLY PRODUCING SOME STRONG WIND GUSTS. THEREAFTER, THE
FORECAST TRENDS DRIER AND WARMER AS THE BERMUDA HIGH BEGINS TO
BUILD WESTWARD WHERE IT WILL BECOME CENTERED OVER THE GULF COAST
BY THIS WEEKEND. THIS WILL RESULT IN A WARMING TREND WITH HEAT
INDICES APPROACHING THE TRIPLE DIGITS NEARLY EACH DAY FROM FRIDAY
INTO EARLY NEXT WEEK.
