SHORT TERM
(THIS AFTERNOON THROUGH WEDNESDAY NIGHT)
ISSUED AT 131 PM CDT TUE JUL 21 2026
UPPER-LEVEL RIDGING BEGINS TO BUILD BACK INTO WEST TEXAS AND
SOUTHEAST NEW MEXICO TODAY. THIS RIDGE WILL BE THE DOMINATE
INFLUENCE ON OUR WEATHER FOR AT LEAST THE NEXT SEVERAL DAYS. HIGHS
TICK UP TODAY RELATIVE TO YESTERDAY. MOST LOCATIONS TOP OUT IN THE
MID-TO-UPPER 90S, WITH SOME 100S ALONG THE RIO GRANDE. SCATTERED
SHOWERS AND THUNDERSTORMS ARE ONCE AGAIN EXPECTED TO DEVELOP IN THE
WESTERN HIGHER TERRAIN THIS AFTERNOON AND EVENING (20-40% CHANCES).
SIMILAR TO YESTERDAY, THE BIGGEST CONCERN WITH STORMS THAT DEVELOP
WOULD BE HEAVY RAIN LEADING TO SOME FLASH FLOODING. CLOUD COVER AND
RAIN CHANCES KEEP HIGHS IN THE 80S AND LOW 90S FOR LOCATIONS IN AND
AROUND THE HIGHER TERRAIN TODAY. OVERNIGHT LOWS IN THE LOW-TO-MID
70S WILL BE COMMONPLACE (LOW-TO-MID 60S IN THE MOUNTAINS).
TEMPERATURES TICK UP AGAIN WEDNESDAY AS THE RIDGE CONTINUES TO
BUILD. HIGHS NEAR OR JUST ABOVE 100 DEGREES ARE FORECAST ACROSS THE
AREA WEDNESDAY (LOW 90S IN/NEAR THE HIGHER TERRAIN). IN FACT, KMAF
HAS ABOUT A 75% CHANCES OF HITTING 100 DEGREES TOMORROW, WHICH WOULD
BE THE FIRST TIME SINCE JULY 4TH. OVERNIGHT LOWS WEDNESDAY LIKEWISE
TREND UP A COUPLE OF DEGREES RELATIVE TO TONIGHT'S. SUBSIDENCE FROM
THE RIDGE LARGELY LIMITS RAIN CHANCES TOMORROW, THOUGH A COUPLE OF
ISOLATED SHOWERS AND STORMS MAY STILL DEVELOP IN THE HIGHER TERRAIN
THANKS TO UPSLOPE FLOW.
SPRANG
LONG TERM
(THURSDAY THROUGH MONDAY)
ISSUED AT 131 PM CDT TUE JUL 21 2026
AN EXPANSIVE UPPER-LEVEL RIDGE WILL DOMINATE THE REGION, SUSTAINING
HOT AND PRIMARILY DRY CONDITIONS THROUGHOUT THE FORECAST PERIOD. BY
FRIDAY, THE RIDGE AXIS WILL SHIFT BRIEFLY TOWARD THE FOUR CORNERS,
ALLOWING WEAK NORTHERLY FLOW ALOFT TO POTENTIALLY STEER MOUNTAIN-
INITIATED CONVECTION FROM NEW MEXICO INTO THE NORTHWESTERN PORTION
OF THE AREA. OTHERWISE, DRY CONDITIONS WILL PERSIST FOR THE NEXT
SEVEN DAYS.
WIDESPREAD TRIPLE-DIGIT TEMPERATURES ARE EXPECTED, WITH MOST AREAS
REACHING 100-105F THROUGHOUT THE WEEK AND INTO THE WEEKEND. EXTREME
HEAT, WITH PEAK TEMPERATURES OF 110-115F, WILL BE CONCENTRATED
ACROSS THE BIG BEND AND RIO GRANDE VALLEY DURING THIS TIME.
