KEY MESSAGES
UPDATED AT 617 AM CDT FRI AUG 28 2026
- LOW TO MEDIUM STORM CHANCES RETURN THIS AFTERNOON, THEN HOT AND
PREDOMINANTLY DRY WEATHER RETURNS THIS WEEKEND INTO NEXT WEEK.
SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 1250 AM CDT FRI AUG 28 2026
SHOWER AND STORM COVERAGE IS BEGINNING TO DWINDLE THIS EVENING AFTER
AN ACTIVE NIGHT, THOUGH SOME SHOWERS AND STORMS MAY REMAIN A FEW
HOURS AFTER MIDNIGHT. DRIER CONDITIONS ARE EXPECTED OVERNIGHT WITH
CLOUD COVER LIMITING TEMPERATURES FROM DROPPING TOO DRASTICALLY,
WITH FORECAST LOWS MAINLY IN THE 70S. REMNANT BOUNDARIES ACROSS
THE AREA AND ABOVE NORMAL MOISTURE WILL ALLOW FOR ANOTHER DAY OF
LOW TO MEDIUM RAIN CHANCES MAINLY DURING THE AFTERNOON HOURS.
COVERAGE SHOULD BE MORE A BIT MORE ISOLATED TODAY COMPARED TO
YESTERDAY DUE TO MORE INFLUENCE FROM THE AMPLIFYING RIDGE TO OUR
WEST. CAN'T RULE OUT SOME GUSTY WINDS WITH ACTIVITY IN STRONGER
STORMS. CLOUD COVER SHOULD BE LESSER BY SUNRISE AND INCREASE AGAIN
DURING THE AFTERNOON WITH HIGH TEMPERATURES IN THE 90S TO AROUND
102 DEGREES. WITH THE INCREASE IN MOISTURE SOME HEAT INDEX VALUES
WILL APPROACH THE 105-108 DEGREE MARK WITH A FEW LOCATIONS
POSSIBLY EXCEEDING HEAT ADVISORY CRITERIA. OVERALL, THINK COVERAGE
WILL BE TOO LOW TO ISSUE ANY HEAT PRODUCTS TODAY. RIDGING
CONTINUES TO SHIFT EASTWARD TONIGHT WITH DRY WEATHER EXPECTED ON
SATURDAY. HOT TEMPERATURES CONTINUE THOUGH DON'T ANTICIPATE ANY
HEAT PRODUCTS AGAIN THIS DAY.
LONG TERM
(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1250 AM CDT FRI AUG 28 2026
RIDGING CONTINUES ITS MOVEMENT EASTWARD WHICH SHOULD BE CENTERED
OVER THE SOUTHERN PLAINS BY SUNDAY. A DISTURBANCE IN THE NORTHERN
GULF WILL MAKE ITS WAY WESTWARD TOWARDS THE TEXAS COAST UNDERCUTTING
THE RIDGE WHICH WILL ALLOW IT TO FLATTEN/ELONGATE INTO THE MIDDLE
MISSISSIPPI VALLEY EARLY NEXT WEEK. IT'S STILL A BIT UNCLEAR EXACTLY
IF THIS DISTURBANCE WILL IMPACT OUR AREA AND BRING RAIN CHANCES, BUT
AT THE LEAST IT DOES LOOK LIKE THE SEABREEZE MAKES A RETURN BY
TUESDAY. IN GENERAL THOUGH, THE LONG TERM FORECAST CONTINUES A HOT
AND PREDOMINANTLY DRY PATTERN.
AVIATION
(12Z TAFS)
ISSUED AT 617 AM CDT FRI AUG 28 2026
EXTENSIVE MID AND HIGH LEVEL CLOUDS WILL LIKELY PREVENT ANY LOW
CLOUD DEVELOPMENT THIS MORNING AS WINDS GENERALLY REMAIN LIGHT AND
VARIABLE. OTHERWISE, WE HAVE ADDED SOME PROB30 GROUPS FOR
AFTERNOON TSRA AT KSAT, KSSF AND KDRT BASED ON RECENT MODEL
TRENDS. SIMILAR TO YESTERDAY, HIGH-BASED STORMS WILL BE CAPABLE
OF PRODUCING GUSTY WINDS, LIGHTNING STRIKES AND HEAVY DOWNPOURS.
MOST OF THE CONVECTION IS EXPECTED TO DECREASE IN COVERAGE WITH
THE LOSS OF DAYTIME HEATING. WINDS SHOULD TREND TO A MORE EAST TO
SOUTHEASTERLY DIRECTION BY EARLY THIS EVENING.
