SHORT TERM
(THIS AFTERNOON THROUGH SATURDAY NIGHT)
ISSUED AT 149 PM CDT FRI SEP 12 2025
SLIGHTLY COOLER WEATHER AND INCREASING CLOUDS AND PRECIPITATION
CHANCES ARE EXPECTED AS END THE WEEK AND GO INTO THE WEEKEND. EARLY
THIS AFTERNOON, VIS/IR SATELLITE IMAGERY INDICATES SCATTERED HIGH
LEVEL CLOUD COVER STREAMING SOUTHWEST TO NORTHEAST, IN ADVANCE OF AN
UPPER LEVEL STORM SYSTEM TO THE WEST OF THE AREA. HIGH PRESSURE AT
THE SURFACE ACROSS WESTERN AND CENTRAL TX AND ASSOCIATED LARGE SCALE
SINKING MOTION CONTINUES TO DEVELOP FARTHER TO THE EAST, LEADING TO
INCREASED LIFT AND MOISTURE IN ADVANCE OF THE APPROACHING STORM
SYSTEM FOR INCREASING CLOUDS AND SLIGHTLY COOLER TEMPERATURES. HIGHS
TODAY ARE FORECAST TO RISE INTO THE MID 80S F TO LOWER 90S F, MID
90S F UPPER TRANS PECOS AND PRESIDIO VALLEY, WITH UPPER 90S F TO 100
F + READINGS ONLY ACROSS THE BIG BEND. SOUTHEAST WINDS AGAIN BECOME
GUSTY THIS AFTERNOON INTO THIS EVENING, WHICH ALONG WITH INCREASED
CLOUD COVER LIMITING OVERNIGHT RADIATIONAL COOLING, KEEPS LOWS A FEW
DEGREES WARMER THAN THURSDAY NIGHT. THIS TRANSLATES TO MID TO UPPER
60S F TO LOWER 70S F, UPPER 50S F TO LOWER 60S F HIGHER ELEVATIONS
FOR TONIGHT.
BY EARLY SATURDAY MORNING, MODELS SHOW BOTH SURFACE HIGH PRESSURE
AND MID TO UPPER RIDGING REDEVELOPING EAST OF THE CENTRAL CONUS,
ALLOWING LEE TROUGHING AND A QUASI-STATIONARY FRONT ACROSS HIGH
PLAINS AND CENTRAL ROCKIES TO PROGRESS EAST/SOUTHEAST. INCREASED
FORCING FOR ASCENT ACCOMPANYING THESE BOUNDARIES IS EXPECTED TO LEAD
TO LOW TO MEDIUM (20%-40%) PROBABILITY OF SHOWERS/STORMS DEVELOPING
ACROSS SE NM PLAINS AND UPPER TRANS PECOS BY SATURDAY MORNING,
EXPANDING EAST AND SOUTHEAST INTO NORTHWEST PERMIAN BASIN (30%-50%)
INTO CENTRAL PERMIAN BASIN DOWN TO PRESIDIO VALLEY (20%-35%) BY LATE
AFTERNOON AND EVENING. CAMS INDICATE SHOWERS/STORMS MOST NUMEROUS
ACROSS EDDY COUNTY PLAINS INTO UPPER TRANS PECOS, WHILE FORCING FOR
ASCENT WITH TROUGHING AND THE APPROACHING COLD FRONT REMAIN GREATEST
ACROSS SE NM PLAINS INTO NORTHWEST PERMIAN BASIN. SHEAR FOR STORM
ORGANIZATION AND LONGEVITY REMAINS WEAK, HOWEVER FORECAST SOUNDINGS
INDICATE STEEPENING LAPSE RATES, SO THERE IS A LOW BUT NONZERO
CHANCE OF LARGE HAIL IN ADDITION TO HEAVY RAIN, GUSTY WINDS AND
LIGHTNING FOR ANY STRONGER STORMS. AS A RESULT OF SCATTERED
SHOWERS/STORMS SATURDAY, HIGHS A FEW DEGREES COOLER THAN TODAY AND
MOSTLY IN THE LOWER 80S F TO LOWER 90S F RANGE, MID 90S F TO 100 F +
NEAR THE BIG BEND ARE ANTICIPATED. RAINFALL OF AT LEAST A FEW TENTHS
OF AN INCH ARE INDICATED FOR MARFA PLATEAU INTO SE NM PLAINS,
ESPECIALLY WESTERN EDDY COUNTY INTO NORTHERN LEA COUNTY WHERE THERE
IS A LOW TO MEDIUM (25-40%) PROBABILITY OF AT LEAST 0.25" TO 0.50"
OF RAIN. WITH FORCING FOR ASCENT DEPARTING TO THE EAST AS THE UPPER
LEVEL STORM SYSTEM REDEVELOPS TO THE EAST OF THE AREA BY SATURDAY
EVENING, SHOWER/STORM CHANCES TAPER OFF AS THEY SHIFT TO CENTRAL
PERMIAN BASIN INTO STOCKTON PLATEAU. HOWEVER, REMAINING CLOUD COVER
AND BOUNDARY LAYER MOISTURE - AS EVIDENCED BY DEW POINT TEMPERATURES
FORECAST TO BE IN THE UPPER 50S F TO LOWER 60S F - KEEP LOWS AT OR A
FEW DEGREES WARMER THAN TONIGHT. MORE UNSETTLED WEATHER AND
CONTINUED "COOL" TEMPERATURES ARE FORECAST INTO NEXT WEEK: READ THE
LONG TERM DISCUSSION FOR MORE.
LONG TERM

THE CENTRAL GREAT PLAINS SUNDAY INTO MONDAY. AS IT DEPARTS, OUR RAIN

50%) RAIN CHANCES ACROSS OUR REGION. BEST RAIN CHANCES CAN BE FOUND
IN AND AROUND THE DAVIS MOUNTAINS SUNDAY AFTERNOON. MONDAY AFTERNOON
SEES LOW TO MEDIUM (10-50%) RAIN CHANCES BECOME RESTRICTED TO THE
WESTERN HALF OF THE AREA, WITH BEST CHANCES OVER THE HIGHER TERRAIN.

FORECAST TO SEE HIGHS RANGING FROM THE UPPER 80S TO LOW 90S EACH
AFTERNOON. MORNING LOWS SHALL MAINLY DIP INTO THE 60S.
