SHORT TERM
(TODAY THROUGH TUESDAY AFTERNOON)
ISSUED AT 301 AM CDT MON JUN 30 2025
WV IMAGERY THIS MORNING SHOWS A MESSY UPPER RIDGE COVERING THE
SOUTHERN CONUS AND AREAS SOUTH, BUTTRESSED BY A TROUGH OFF THE
CALIFORNIA COAST, AND ANOTHER CENTERED OVER GEORGIA. WEST TEXAS
AND SOUTHEAST NEW MEXICO SIT UNDER A COL, AND A SW-NE-ORIENTED
SHEAR AXIS IS DEVELOPING OVERHEAD AS A RESULT. THIS SHOULD RESULT
IN EXCELLENT CHANCES OF RAIN OVER THE NEXT COUPLE OF DAYS.
KMAF 00Z RAOB CAME IN WITH A PWAT OF 1.39", A LITTLE OVER THE
CLIMATOLOGICAL 90TH PERCENTILE OF 1.37". THIS IS AN INCREASE FROM
24 HOURS AGO, AND THE LATEST NAM PUTS PWATS AT 1.70" AT 00Z
TUESDAY. CLIMATOLOGICAL MAXIMUM IS 1.66". NAEFS ENSEMBLES FORECAST
A PWAT MINIMUM OF 1.8 STD DEVS ABOVE NORMAL INTO NEXT WEEKEND.
THIS ALL SUGGESTS THE AMS BECOMING MORE TROPICAL IN NATURE OVER
THE NEXT COUPLE OF DAYS. CURRENT KMAF RADAR BIAS IS HOLDING STEADY
AT 1.01, INDICATING THAT THE AMS IS AT LEAST MINIMALLY TROPICAL
ALREADY. W/THIS IN MIND, WE'VE PUT THE KMAF 88D IN TROPICAL MODE
TO BETTER ESTIMATE RAINFALL.
THAT SAID, LAST NIGHT'S CONVECTION COVERED DAWSON COUNTY WITH A
GOOD CHUNK OF WATER, AND WE'LL ADD IT TO THE CURRENT FLOOD WATCH.
THE WATCH MAY NEED TO BE EXTENDED, BUT CAMS AND SHORT-TERM
GUIDANCE SUGGESTS THIS EVENING SHOULD BE BEST CHANCE OVERALL FOR
RAIN, SO WE'LL LET THE NEXT SHIFT PULL THAT TRIGGER IF AN
EXTENSION IS WARRANTED. FOR THOSE WHO LIKE COOLER WEATHER,
DECREASING THICKNESSES UNDER THE COL AND PLENTY OF CLOUD COVER
WILL SHAVE 3-4 F OFF OF YESTERDAY'S HIGHS.
TONIGHT, CONVECTION WILL BE ONGOING, W/BEST CHANCES IN THE NORTH
ALONG A FRONTAL BOUNDARY, GRADUALLY DIMINISHING AFTER 06Z. THE LLJ
LOOKS RATHER TEPID COMPARED TO THE PAST FEW NIGHTS AND, IF
CONVECTION PANS OUT AS EXPECTED, THIS WILL COMBINE W/RAIN/EVAP
COOLING AND OUTFLOWS TO COOL OVERNIGHT LOWS WITHIN A DEGREE OR TWO
OF NORMAL.
TUESDAY, THE COL DEVELOPS INTO A SORT OF INVERTED TROUGH OVER FAR
WEST TEXAS AND SOUTHERN NEW MEXICO, RAMPING UP CONVECTIVE CHANCES
ALONG AND WEST OF THE PECOS. THE FRONT, DECREASING THICKNESSES,
AND CLOUDS/RAIN WILL YIELD THE LOWEST TEMPERATURES OF THIS
FORECAST AS HIGHS COME IN SOME 10-15 F BELOW NORMAL.
APART FROM PUTTING A DENT IN DROUGHT CONDITIONS ACROSS WEST TEXAS
AND SOUTHEAST NEW MEXICO, THESE BENEFICIAL RAINS WILL ALSO HELP
TO MINIMIZE FIRE THREATS FROM 4TH OF JULY FIREWORKS AS SOILS
SATURATE.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 301 AM CDT MON JUN 30 2025
FORECAST REMAINS ON TRACK FOR A WARMING AND DRYING TREND NEAR THE
END OF THE WEEK CONTINUING THROUGH THIS WEEKEND INTO EARLY NEXT
WEEK, EVEN AS RISK FOR HEAVY RAIN IN SHOWERS/STORMS PERSISTS FOR
DAVIS MOUNTAINS - WITH AT LEAST MEDIUM POPS AREAWIDE WEDNESDAY AND
THURSDAY AFTERNOONS AND EVENINGS DECREASING TO MEDIUM POPS FRIDAY
INTO THE WEEKEND ALONG AND SOUTH AND SOUTHWEST OF DAVIS
MOUNTAINS. DETERMINISTIC AND ENSEMBLE MODELS CONTINUE TO DEPICT
MID TO UPPER RIDGING NORTH AND WEST OF THE AREA DEVELOPING SOUTH
AND EAST CLOSER TO THE AREA, AS 500 MB GEOPOTENTIAL HEIGHTS REMAIN
ABOVE 588 DECAMETERS AND 1000-500 MB THICKNESSES BETWEEN 578 AND
582 DECAMETERS, INDICATING SEASONABLE WARM AND EXPANSIVE AIR
COLUMNS OVER THE AREA THROUGHOUT THE EXTENDED. BEFORE CORE OF
RIDGING AND ACCOMPANYING SUBSIDENCE AND CORE OF WARMER
TEMPERATURES DEVELOPS CLOSER TO THE AREA, PASSAGE OF SHORT WAVES
IN WEAKNESSES IN FLOW SOUTH AND EAST OF RIDGING ARE EXPECTED TO
CONTINUE AIDING FORCING FOR ASCENT IN MID TO UPPER TROPOSPHERE.
WPC SURFACE ANALYSIS ALSO DEPICTS CONTINUED LEE TROUGHING
EXTENDING SOUTHWEST TO NORTHEAST OVER SOUTHEAST INTO CENTRAL NM
AND MERIDIONALLY FROM GUADALUPES INTO PRESIDIO VALLEY, AS A WEAK
COLD FRONT MOVING SOUTH WASHES OUT OVER NORTHERN PORTIONS OF THE
AREA. THIS MAINTAINS HUMID, UPSLOPE SOUTHEAST WINDS WITH DEW POINT
TEMPERATURES IN THE LOWER 60S TO LOWER 70S F AND SCATTERED TO
BROKEN CLOUD COVER, AS WELL AS FORCING FOR ASCENT CLOSER TO THE
SURFACE. LOW TO MEDIUM POPS AREAWIDE TUESDAY NIGHT WITH LOWS
FALLING INTO MID 60S TO LOWER 70S F GIVE WAY TO POPS INCREASING TO
MEDIUM TO HIGH OVER DAVIS MOUNTAINS AND POINTS SOUTH AND
SOUTHWEST WEDNESDAY AFTERNOON INTO EVENING WHILE REMAINING IN
MEDIUM RANGE EVERYWHERE ELSE, BEFORE DECREASING TO MEDIUM
SOUTHWEST OF PECOS RIVER AND PORTIONS OF NORTHERN PERMIAN BASIN
SOUTH WEDNESDAY NIGHT. WITH CLOUD COVER LIMITING DAYTIME HEATING
AND EVAPORATIONAL COOLING FROM RAINFALL LIMITING WARMING OF
SURFACE LAYER, HIGHS WEDNESDAY AGAIN REMAIN ON THE COOLER SIDE FOR
THIS TIME OF YEAR, TRANSLATING TO MID 70S TO LOWER 80S AND UPPER
80S TO MID 90S NORTHEAST PERMIAN BASIN AND SOUTHERNMOST RIO
GRANDE. LOWS LIKEWISE REMAIN MILD AS DEW POINT TEMPERATURES IN THE
LOWER 60S TO LOWER 70S F AND SCATTERED TO BROKEN CLOUD COVER
LIMIT RADIATIONAL COOLING, WITH MID TO UPPER 60S F WEST OF EASTERN
PERMIAN BASIN AND EASTERN STOCKTON PLATEAU INTO TERRELL COUNTY,
AND UPPER 60S TO LOWER 70S EASTERN PERMIAN BASIN INTO TERRELL
COUNTY AND RIO GRANDE VALLEYS.
THURSDAY, POPS STILL RISE INTO THE MEDIUM TO HIGH RANGE IN THE
AFTERNOON AND EVENING. HOWEVER, WITH BUILDING RIDGING, FORCING FOR
ASCENT IS EXPECTED TO BE MORE FROM HEATING OF ELEVATED TERRAIN
AND UPSLOPE FLOW EAST OF LEE TROUGHING RATHER THAN FREQUENT SHORT
WAVE PASSAGES. WITH DECREASED COVERAGE OF PRECIPITATION OVER SE NM
PLAINS, HIGHS RISE BY A FEW DEGREES INTO THE UPPER 70S TO LOWER
80S, WHILE REMAINING SIMILAR TO WEDNESDAY ELSEWHERE, EVEN AS
THURSDAY NIGHT LOWS REMAIN SIMILAR TO WEDNESDAY NIGHT UNDER MOSTLY
CLOUDY SKIES LIMITING RADIATIONAL COOLING. UNLIKE PREVIOUS RUNS,
FRIDAY NOW MARKS THE SHIFT TO LOWER POPS INTO THE LOW TO MEDIUM
RANGE EACH AFTERNOON AND EVENING SOUTHWEST OF PECOS RIVER, AND
REMAINING IN MEDIUM RANGE OVER DAVIS MOUNTAINS AND PRESIDIO
VALLEY, WITH MEDIUM POPS EXTENDING INTO WESTERN EDDY COUNTY PLAINS
CLOSER TO NEAR SURFACE FORCING OF LEE TROUGHING OVER SOUTHEAST NM
AND WESTERN HIGHER TERRAIN OF TX LATER AGAIN IN THE WEEKEND.
HOWEVER, WITH CORE OF RIDGING DEVELOPING CLOSER TO THE AREA, WIND
TRAJECTORIES LESS CONSISTENTLY FROM THE SOUTHEAST AND FROM THE
GULF RESULT IN DEW POINT TEMPERATURES DECREASING INTO THE UPPER
50S TO MID 60S F RANGE. IT WILL STILL BE HUMID, BUT NOT AS HUMID
AS EARLIER THIS WEEK. HIGHS IN MID 80S TO MID 90S FRIDAY RISE INTO
MID TO UPPER 90S, UPPER 80S HIGHER ELEVATIONS, AND UPPER 90S TO
TRIPLE DIGITS ALONG RIO GRANDE BY THE WEEKEND, WITH WARMER
TEMPERATURES LIKEWISE RESULTING IN LOWS ONLY FALLING INTO THE 70S
F OVER MOST OF THE AREA APART FROM HIGHER ELEVATIONS AND NORTHERN
AND CENTRAL PERMIAN BASIN INTO NORTHWEST PERMIAN BASIN, WHERE LOWS
WILL CONTINUE TO FALL INTO THE 60S F.
AFTER TUESDAY, NBM GRIDS ARE INDICATING HIGHEST RAINFALL AMOUNTS
0.75" TO 1.00" AND UP TO 1.25" OVER DAVIS MOUNTAINS AND MARFA
PLATEAU, WITH 0.50" TO 0.75" SOUTHERN RIO GRANDE BASINS INTO
SOUTHERN STOCKTON PLATEAU AND TERRELL COUNTY, AND A FEW TENTHS OF
AN INCH ELSEWHERE - EXCEPT FOR A FEW HUNDREDTHS OF AN INCH
EASTERNMOST PERMIAN BASIN. MOST OF THIS RAIN NORTHEAST OF PECOS
RIVER IS LIKELY TO FALL ON WEDNESDAY AND THURSDAY WHEN POPS WILL
STILL BE AT LEAST IN THE MEDIUM RANGE AREAWIDE. LOWEST PERCENTILE
ENSEMBLES STILL SHOW AT LEAST A FEW TENTHS OF AN INCH AREAWIDE
THROUGH EARLY NEXT WEEK, WITH SPREADS 0.75" TO 1.25" INDICATING
POTENTIAL FOR HEAVY CONVECTIVE RAINS WHERE SHOWERS/STORMS DO
OCCUR. A MEDIUM TO HIGH PROBABILITY OF RAINFALL AT LEAST 0.50" TO
0.75" AREAWIDE, MEDIUM TO HIGH PROBABILITY OF 1.00" TO 1.25" OVER
DAVIS MOUNTAINS AND MEDIUM PROBABILITIES OF RAINFALL STILL UP TO
2.00" IN SOME ENSEMBLE MEMBERS FOR THE DAVIS MOUNTAINS ARE SHOWING
A SIGNAL FOR THE RISK OF FLASH FLOODING TO CONTINUE FOR THE DAVIS
MOUNTAINS THROUGH NEXT WEEK. WE WILL CONTINUE TO MONITOR
FORECASTS TO SEE HOW LOCATION, TIMING, AND MAGNITUDE OF RAINFALL
CHANGES FOR THIS NEXT SERIES OF RAIN EVENTS.
