DISCUSSION
ISSUED AT 232 AM CDT SAT AUG 29 2026
TODAY...
DRIER WEATHER AND LESS HUMIDITY IS EXPECTED TODAY AS A DRIER AIRMASS
MOVES INTO THE NORTHERN HALF OF THE CWA. LATEST SURFACE ANALYSIS HAS
A DRY FRONT DRAPED THROUGH THE SOUTHERN PORTIONS OF THE CWA. NORTH
OF THE FRONT SURFACE DEW POINTS WILL DROP INTO THE 60S AND PWATS
WILL DROP BELOW AN INCH AND A HALF. THE SURFACE HIGH WILL CONTINUE
SHIFTING EAST THROUGH SATURDAY RESULTING IN A NORTHEAST TO EASTERLY
WIND. THE LARGE MID LEVEL RIDGE TO OUR WEST WILL BEGIN SPREADING
BACK TO THE EAST OVER OUR CWA. TOGETHER THESE FEATURES WILL RESULT
IN DRIER WARMER CONDITIONS TODAY./22/OAJ/
TONIGHT AND SUNDAY...
AN UPPER-LVL HIGH OVER THE SOUTHWEST & TEXAS WILL EXPAND AND
PROGRESS EASTWARD TOWARDS THE SOUTHEAST. A CUT-OFF LOW PRESSURE
CENTER NEAR GULF STATES WILL TRACK WESTWARD, SHIFTING RAIN CHANCES
INTO THE PINE BELT TOMORROW. AS THE HIGH PROGRESSES, HEAT INDICES
ARE EXPECTED TO BREAK INTO THE TRIPLE DIGITS TOMORROW; ATTRIBUTED
MOSTLY TO HIGHER HUMIDITY VALUES.
THE REST OF THE WEEK...
THE AFOREMENTIONED HIGH WILL SETTLE OVER THE SOUTHEAST CONUS AROUND
TUESDAY, LINGERING THROUGH THE REST OF THE WEEK. THROUGHOUT THE WEEK
DIURNALLY DRIVEN SHOWERS AND THUNDER ARE EXPECTED TO PROGRESS SLOWLY
NORTHWARD EACH DAY DRIVEN BY INCREASED MOISTURE ADVECTION. AS A
RESULT OF INCREASED MOISTURE/RH, DANGEROUS HEAT CONCERNS ARE
EXPECTED TO RETURN BY MID-WEEK -THROUGHOUT AREAS THAT DO NOT RECEIVE
PRECIPITATION- DRIVING HEAT INDICES NEAR OR IN EXCESS OF 105F. HWO
GRAPHICS MAY BE NEEDED BUT TIMING IS STILL SEVERAL DAYS AWAYS.
AS ALWAYS DURING THIS TIME OF YEAR, WE WILL CONTINUE TO MONITOR THE
GULF FOR ANY TROPICAL SYSTEM DEVELOPMENT. THERE ARE NO TROPICAL
SYSTEMS FORECAST TO IMPACT FORECAST ZONES DURING THE PERIOD./SW/OAJ/
