MESOSCALE UPDATE
ISSUED AT 834 PM CDT THU AUG 7 2025
REST OF TONIGHT...SCARCE CONVECTION THAT DEVELOPED ACROSS EAST &
SOUTHEAST MISSISSIPPI LATE THIS AFTERNOON, IS DISSIPATING THIS
EVENING. THE LINGERING CLOUD COVER ASSOCIATED WITH IT WILL ERODE
OVER THE NEXT FEW HOURS, WITH MOSTLY CLEAR SKIES EXPECTED OVERNIGHT
WITH SOME PATCHY SHALLOW GROUND FOG POSSIBLE ACROSS MAINLY SOUTHERN
PORTIONS OF THE AREA TOWARD DAY BREAK FRIDAY. OTHERWISE, QUIET
CONDITIONS WILL EXIST ACROSS THE AREA TONIGHT, WITH LOWS FALLING
INTO THE LOW AND MIDDLE 70S.
I'LL MAKE SOME MINOR TWEAKS TO HOURLY ELEMENTS OF THE FORECAST BASED
ON CURRENT TRENDS, BUT THE OVERALL FORECAST IS CURRENTLY IN GOOD
SHAPE AND NO MAJOR CHANGES WILL BE MADE ON THIS EVENING'S UPDATE.

DISCUSSION
ISSUED AT 1258 PM CDT THU AUG 7 2025
TYPICAL SUMMERTIME WEATHER CONDITIONS ARE EXPECTED ACROSS OUR
FORECAST AREA INTO LATE NEXT WEEK. A STOUT UPPER-LEVEL RIDGE OF HIGH
PRESSURE OVER THE DESERT SOUTHWEST WILL BREAK DOWN OVER THE NEXT FEW
DAYS AND ALLOW A MORE ZONAL FLOW PATTERN TO DEVELOP OVER THE
NORTHERN CONUS. TO THE SOUTH, A TROPICAL WAVE WILL BRING THE RETURN
OF EASTERLY FLOW AND DEEPER 2+ INCH PWAT AIR TO OUR REGION. THIS
WILL RESULT IN BETTER RAIN CHANCES AND MORE HUMIDITY BY THE EARLY
PARTS OF NEXT WEEK. AT THIS TIME, IT APPEARS THAT SOME PARTS OF THE
FORECAST AREA COULD END UP WITH DANGEROUS HEAT STRESS CONDITIONS
(HEAT INDEX >105), BUT RAIN CHANCES LIMIT CONFIDENCE OF HEAT IMPACTS
AT THIS TIME. /NF/
AVIATION
(00Z TAFS)
ISSUED AT 630 PM CDT THU AUG 7 2025
VFR FLIGHT CATEGORIES WILL PREVAIL AT AREA TAF SITES THROUGH MUCH
OF THIS 00Z FORECAST PACKAGE. THERE WILL BE A 2-4 HOUR PERIOD
AROUND DAY BREAK FRIDAY, WHERE CATEGORIES COULD BRIEFLY FALL TO
MVFR CATEGORIES DUE TO PATCHY SHALLOW GROUND FOG. THIS WILL
QUICKLY ERODE AFTER SUNRISE, WITH VFR YET AGAIN PREVAILING. WINDS
WILL SUBSIDE THIS EVENING, REMAINING CALM TO LIGHT FROM THE EAST
AROUND 3 KNOTS OVERNIGHT INTO FRIDAY MORNING. /19/
