KEY MESSAGES
UPDATED AT 1217 AM CDT FRI JUN 26 2026
- DRY WEATHER ALONG WITH NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES
CONTINUE THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK.
- ELEVATED HEAT INDEX VALUES CONTINUE, ESPECIALLY ALONG AND EAST
OF I-35 AND ACROSS MOST THE RIO GRANDE PLAINS.
SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 1217 AM CDT FRI JUN 26 2026
THE MID AND UPPER LEVEL SUBTROPICAL RIDGE WILL REMAIN IN PLACE
ACROSS THE SOUTH-CENTRAL U.S. AND NORTHERN MEXICO THROUGH THE END OF
THE WEEK. WE EXPECT TO SEE A PERSISTENCE OF DRY WEATHER ALONG WITH
NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES ACROSS SOUTH-CENTRAL
TEXAS. HIGHS WILL RANGE FROM NEAR 90 IN THE HILL COUNTRY TO NEAR 100
DEGREES ALONG THE RIO GRANDE. OVERNIGHT LOWS WILL BE IN THE 70S.
SIMILAR TO THE LAST COUPLE OF DAYS, WE ALSO EXPECT TO SEE GUSTY
SOUTHEAST WINDS CONTINUE, MAINLY DURING THE LATE MORNING THROUGH
EARLY EVENING HOURS. THE EXCEPTION TO THIS HAS BEEN OVER THE HIGHER
TERRAIN OF THE HILL COUNTRY WHERE SOME TEXAS TECH MESONET SITES HAVE
SHOWN SOME GUSTY CONDITIONS PERSISTING THROUGH THE OVERNIGHT HOURS.
THE GUSTY WINDS WILL SERVE TO INCREASE THE MIXING AND REDUCING OF
DEW POINT TEMPERATURES IN THE AFTERNOON HOURS DURING PEAK HEATING.
THIS SHOULD KEEP HEAT INDEX VALUES BELOW HEAT ADVISORY LEVELS
THROUGH SATURDAY.
LONG TERM
(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1217 AM CDT FRI JUN 26 2026
THE CENTER OF THE SUBTROPICAL HIGH WILL GRADUALLY SHIFT EASTWARD
INTO THE LOWER MISSISSIPPI RIVER VALLEY EARLY NEXT WEEK AS A DEEP
UPPER TROUGH DEVELOPS OVER THE WESTERN U.S. OVERALL, THIS PATTERN
WILL NOT RESULT IN MUCH CHANGE TO OUR SENSIBLE WEATHER. WE EXPECT TO
SEE A CONTINUATION OF NEAR TO ABOVE NORMAL TEMPERATURES AND DRY
CONDITIONS FOR THE REGION. WITH A FAIRLY PERSISTENT AREA OF SURFACE
LOW PRESSURE OVER EASTERN COLORADO/WESTERN NEBRASKA AND KANSAS AND
SURFACE HIGH PRESSURE OVER THE GULF, WE WILL CONTINUE TO SEE GUSTY
SOUTHEAST WINDS WELL INTO THE MIDDLE OF THE UPCOMING WEEK. AS
MENTIONED ABOVE, THESE WINDS WILL HELP MIX (LOWER) AFTERNOON DEW
POINT TEMPERATURES, WHICH SHOULD LARGELY KEEP MOST AREAS BELOW HEAT
ADVISORY LEVELS.
