SHORT TERM
(TODAY AND TONIGHT)
ISSUED AT 1238 AM CDT SAT SEP 5 2026
WITH THE DEPARTURE OF EDOUARD'S REMNANTS, A HIGH-AMPLITUDE RIDGE
HAS DEVELOPED OVER THE GREAT PLAINS. WITH HEIGHTS INCREASING INTO
THE WEEKEND ALONG WITH SURFACE HIGH PRESSURE AND CLEAR SKIES,
TEMPERATURES ARE EXPECTED TO BE 7-10 DEGREES ABOVE NORMAL. HIGHS
ACROSS NORTH TEXAS WILL BE IN THE 99-103 RANGE, WHILE CENTRAL
TEXAS HIGHS WILL BE SLIGHTLY COOLER (95-100) DUE TO THIS WEEK'S
RAINFALL.
DURING PEAK DIURNAL HEATING, SCATTERED SHOWERS AND THUNDERSTORMS
ARE EXPECTED TO DEVELOP (30-50% CHANCE) ACROSS PORTIONS OF THE
BRAZOS VALLEY, WITH MUCH MORE ISOLATED ACTIVITY POSSIBLE (10-20%
CHANCE) ALONG AND EAST OF THE I-35 CORRIDOR, AND ALONG AND SOUTH
OF THE I-20 CORRIDOR.
..A DISCUSSION ON THE HEAT ADVISORY
WITH STRONG MIXING EXPECTED ACROSS MUCH OF NORTH TEXAS, DESPITE
AFTERNOON HIGHS IN THE 99-103 RANGE, DEW POINTS IN THE LOW AND MID-60S
WILL BE INSUFFICIENT FOR HEAT INDICES REQUIRING A HEAT ADVISORY.
THE CURRENT FORECAST THIS AFTERNOON HAS HEAT INDICES ACROSS MUCH
OF NORTH TEXAS IN THE 101-104 RANGE. WHILE ISOLATED POCKETS OF
105-106 WILL BE POSSIBLE, COVERAGE AND CONFIDENCE IN THESE HEAT
INDICES REMAIN TOO LOW TO ISSUE A HEAT ADVISORY FOR MUCH OF NORTH
TEXAS AT THIS TIME. THE EXCEPTION LOOKS TO BE ACROSS PORTIONS OF
NORTHEAST TEXAS WHERE DEEPER BOUNDARY LAYER MOISTURE WILL EXHIBIT
A STRONGER RESISTANCE TO DIURNAL MIXING. FRIDAY AFTERNOON
(YESTERDAY), HEAT INDICES NORTHEAST OF A LINE FROM CANTON TO
SHERMAN RANGED FROM 104 TO 106. WITH RIDGING CONTINUING TO BUILD
HIGHER HEIGHTS OVER THE REGION AND AN INCREASINGLY WELL
ESTABLISHED TROPICAL AIRMASS IN PLACE AT THE SURFACE FROM
NORTHEAST TEXAS EASTWARD, IT IS EXPECTED TO HAVE AFTERNOON HEAT
INDICES WHERE THE ADVISORY WAS ISSUED IN THE 105-106 RANGE AGAIN TODAY.
THE POTENTIAL FOR ISOLATED SHOWERS AND THUNDERSTORMS ALONG AND
SOUTH OF THE I-20 CORRIDOR AND EAST OF I-35 HAS PRECLUDED THE
ISSUANCE OF A HEAT ADVISORY AT THIS TIME IN THIS AREA. WHILE
AFTERNOON DEW POINTS WILL LIKELY REMAIN IN THE 70S, CLOUD COVER
FROM DIURNALLY DRIVEN CONVECTION WILL COMPLICATE THE FORECAST AND
LIKELY KEEP MUCH OF THIS AREA IN THE 90S DURING THE AFTERNOON AND
EVENING. AS SUCH, HEAT INDEX VALUES WILL LIKELY BE JUST SHY OF
HEAT ADVISORY CRITERIA (IN THE 100-104 RANGE).
LASTLY, THE HEAT ADVISORY ACROSS PORTIONS OF SOUTHWEST OKLAHOMA
AND NORTH-CENTRAL TEXAS IS PRIMARILY DRIVEN BY AFTERNOON AIR
TEMPERATURES IN THE 103-105 DEGREE RANGE. THESE HOT TEMPERATURES
SHOULD REMAIN JUST NORTH AND NORTHWEST OF OUR NORTHWESTERN
COUNTIES, KEEPING AFTERNOON CONDITIONS JUST SHY OF HEAT ADVISORY
CRITERIA.
LONG TERM
(SUNDAY THROUGH FRIDAY)
ISSUED AT 1238 AM CDT SAT SEP 5 2026
THE WEATHER PATTERN THIS WEEKEND IS EXPECTED TO STAGNATE WITH
STRONG UPPER-LEVEL RIDGING DOMINATING THE CENTRAL AND SOUTHEASTERN
CONUS. AS SUCH, ABOVE AVERAGE TEMPERATURES IN THE UPPER-90S AND
LOWER-100S WILL CONTINUE SUNDAY INTO THE UPCOMING WORK WEEK. THERE
IS, HOWEVER, ONE EXCEPTION TO THIS OVERALL TREND. A SUBTLE TROPICAL
WAVE OVER THE GULF WILL WEAKEN HEIGHTS JUST ENOUGH OVER PORTIONS
OF EAST-CENTRAL AND SOUTHEAST TEXAS TO BRING LOW CHANCES (10-20%)
FOR ISOLATED SHOWERS AND THUNDERSTORMS EACH DAY TO THE BRAZOS
VALLEY.
