CURRENT SATELLITE IMAGERY SHOWS THE UPPER LOW IN PORTIONS OF
SOUTHEAST NEW MEXICO EXTENDING INTO THE UPPER TRANS PECOS IN WEST
TEXAS. A PRONOUNCED MESOSCALE CONVECTIVE VORTEX (MCV) IS SHOWN SOUTH
OF VAN HORN MOVING EAST-SOUTHEAST TOWARDS THE DAVIS MOUNTAINS.
ANOTHER MESOSCALE LOW LOOKS TO BE PREVALENT ACROSS THE EDDY COUNTY
PLAINS. BOTH FEATURES WILL SUPPLY ADDITIONAL LIFT FOR WIDELY
SCATTERED TO NUMEROUS SHOWER/STORM DEVELOPMENT LATER THIS AFTERNOON
AND EVENING. THE HIGHEST COVERAGE OF SHOWERS/STORMS WILL BE ACROSS
THE DAVIS MOUNTAINS, LOWER TRANS PECOS, AND BIG BEND REGION. GIVEN
QUITE A BIT OF RAIN HAS FALLEN IN THESE AREAS OVER THE PAST COUPLE
OF DAYS, THIS WILL HEIGHTEN THE FLASH FLOOD THREAT. ISOLATED TO
WIDELY SCATTERED STORMS ARE EXPECTED ELSEWHERE TODAY. THE 12Z MAF
SOUNDING SHOWED A RECORD DAILY PWAT (1.82"), SLOW STORM MOTIONS, AND
A VERY MOIST VERTICAL PROFILE ESPECIALLY IN THE MID-LEVELS OF THE
ATMOSPHERE. THESE PARAMETERS INDICATE THAT SHOWERS/STORMS WILL
CONTINUE TO PRODUCE HEAVY RAINFALL. LIKE YESTERDAY, FORECAST
SOUNDINGS DEPICT INVERTED-V PROFILES, SUFFICIENT DCAPE, ABUNDANT
INSTABILITY, AND MODEST LAPSE RATES SUPPORTING THE THREAT OF
ISOLATED GUSTY WINDS AND HAIL UP TO THE SIZE OF QUARTERS WITH THE
STRONGEST STORMS.
TONIGHT, THE UPPER LOW SHIFTS INTO FAR WEST TEXAS. LINGERING SHOWERS
AND STORMS WILL BE CONFINED ACROSS PORTIONS OF SOUTHWEST TEXAS
INCLUDING THE BIG BEND AND DAVIS MOUNTAINS. AS A RESULT, THE FLASH
FLOOD THREAT CONTINUES THROUGH THE OVERNIGHT TO EARLY MORNING HOURS
FOR THESE AREAS. THIS ACTIVITY LOOKS TO STICK AROUND SIMILAR AREAS
AND IN THE LOWER TRANS PECOS. RAIN CHANCES BECOME LIMITED TO THE
WESTERN HALF OF THE FORECAST AREA AS THE LOW PIVOTS AWAY FROM THE
REGION MONDAY AFTERNOON. HIGH TEMPERATURES BOTH DAYS WILL RANGE FROM
THE MID 80S TO MID 90S FOR MOST LOCATIONS WITH MONDAY BEING SLIGHTLY
WARMER.

LONG TERM
(TUESDAY THROUGH SATURDAY)
ISSUED AT 111 PM CDT SUN JUL 19 2026
WARMER AND MUCH DRIER CONDITIONS TAKE SHAPE AS UPPER-LEVEL RIDGING
RETURNS. TUESDAY WILL BE THE LAST DAY OF APPRECIABLE RAIN CHANCES
MAINLY WEST OF THE PECOS RIVER. GIVEN SOME AREAS HAVE ALREADY SEEN
SEVERAL ROUNDS OF RAINFALL, THE RISK OF FLASH FLOODING SHALL
CONTINUE TO BE A CONCERN TUESDAY AFTERNOON BEFORE STORMS DIMINISH BY
THE EVENING. BY MID WEEK, THE AFOREMENTIONED RIDGE BUILDS INTO THE
SOUTHERN PLAINS BECOMING THE DOMINANT WEATHER FEATURE CREATING MUCH
WARMER AND DRIER CONDITIONS AREAWIDE. THIS WILL GRADUALLY INCREASE
TEMPERATURES IN THE LOW TO UPPER 90S. GUIDANCE HAS BEEN TRENDING
TOWARDS MANY LOCATIONS HITTING THE TRIPLE DIGITS BY LATE WEEK INTO
THE WEEKEND.
