SHORT TERM
(THIS EVENING THROUGH TUESDAY)
ISSUED AT 247 PM CDT MON MAR 9 2026
AN UPPER LEVEL LOW CAN BE SEEN SPINNING OFF THE COAST OF BAJA
CALIFORNIA ON WATER VAPOR SATELLITE IMAGERY. UPPER LEVEL MOISTURE
BEING BROUGHT UP BY THE LOW IS PUSHING UP INTO TEXAS THIS MORNING,
BRINGING MID AND HIGH CLOUDS. MEANWHILE, SOME LOW LEVEL MOISTURE IN
SOUTHERLY FLOW BROUGHT SOME MORNING BROKEN TO OVERCAST STRATUS TO
PORTIONS OF THE CONCHO VALLEY, HEARTLAND AND THE I-10 CORRIDOR.
LATEST VISIBLE SATELLITE IMAGERY SHOWS GOOD CLEARING OF THESE LOW
CLOUDS, AND EXPECT CONTINUED CLEARING OF THESE CLOUDS THROUGH THE
REST OF THE AFTERNOON. TEMPERATURES SHOULD BE ABLE TO WARM INTO THE
LOW TO MID 80S THIS AFTERNOON WITH AT LEAST DECENT INSOLATION FOR
MOST OF THE AREA AND A WARMER 850 MB THERMAL RIDGE.
THE LOW WILL SLOWLY MOVE INLAND INTO BAJA AND NW MEXICO LATE TODAY
AND TONIGHT, WITH THE LOW WEAKENING INTO AN OPEN POSITIVELY TILTED
TROUGH AS IT MOVES INTO NORTHERN MEXICO/FAR WEST TEXAS TUESDAY
AFTERNOON. TONIGHT, EXPECT WARM LOW TEMPERATURES IN THE LOW TO UPPER
60S DUE TO CLOUDS AND SOUTHERLY BREEZES. TUESDAY MORNING, MORE MID
AND UPPER LEVEL MOISTURE AND SOME INSTABILITY ALOFT, IN ADDITION TO
ENHANCED LIFT FROM THE APPROACHING TROUGH, WILL BRING ISOLATED TO
SCATTERED LIGHT SHOWERS AND PERHAPS A FEW THUNDERSTORMS. TUESDAY
AFTERNOON, EXPECT AT LEAST PARTIAL CLEARING OF LOW/MID/HIGH CLOUDS
ACROSS THE AREA, ALLOWING FOR INCREASED INSTABILITY (MLCAPE REACHING
500-1500 J/KG). MEANWHILE, MODELS INDICATE THAT BY MID AFTERNOON,
THE DRYLINE WILL STRETCH FROM CHILDRESS SOUTH-SOUTHWEST THROUGH
IRAAN AND INTO SANDERSON. THE COMBINATION OF INSTABILITY, STRONG
LIFT WITH 500MB HEIGHT FALLS/DIFLUENCE ALOFT AS THE TROUGH AXIS
APPROACHES, AND INCREASED MOISTURE (SURFACE DEWPOINTS UP TO 62 F
EAST OF THE DRYLINE AND PRECIPITABLE WATER OF 1.2-1.5 INCHES) WILL
LEAD TO WIDESPREAD DEVELOPMENT OF THUNDERSTORMS ALONG AND JUST EAST
OF THE DRY LINE BETWEEN MID AND LATE AFTERNOON. LATEST HRRR RUN
TENDS TO FAVOR LOCATIONS WEST OF A HASKELL TO SONORA LINE FOR THE
MID TO LATE AFTERNOON STRONG TO SEVERE STORM ACTIVITY. MEANWHILE,
HREF FORECAST SOUNDINGS INDICATE EFFECTIVE SHEAR INCREASING TO 50-70
KT AND 0-3 KM STORM RELATIVE HELICITY (SRH) INCREASING TO 150-200
M2/S2, BOTH OF WHICH STRONGLY FAVOR SUPERCELL FORMATION. ALSO, THE 0-
1 KM SRH IS PROGGED TO BE ELEVATED AS WELL (100-200 M2/S2), WHICH
INDICATES AN INCREASED TORNADO RISK. THUS, THE STORM PREDICTION
CENTER'S 11 AM UPDATE HAS MOST OF OUR FORECAST AREA IN AN ENHANCED
RISK FOR SEVERE THUNDERSTORMS FOR TUESDAY AND TUESDAY NIGHT, WITH A
5% TORNADO RISK, 15-30% DAMAGING WIND RISK (WITH PEAK WIND GUSTS OF
74+ MPH), AND 15-30% LARGE HAIL RISK (WITH HAILSTONES OF 2"+
DIAMETER). SEE THE LONG TERM DISCUSSION BELOW FOR THE DETAILS ON THE
REST OF THIS SEVERE THUNDERSTORM EVENT TUESDAY NIGHT. FINALLY, DUE
TO THE INCREASED MOISTURE AND EXPECTED WIDESPREAD THUNDERSTORMS,
HEAVY RAINFALL COULD LEAD TO SOME FLASH FLOODING AND URBAN/SMALL
STREAM FLOODING. THEREFORE, THERE IS A SLIGHT RISK OF EXCESSIVE
RAINFALL ACROSS MOST OF THE AREA TUESDAY AFTERNOON AND TUESDAY NIGHT.
WITH THE INCREASE IN CLOUD COVER TOMORROW AND WEAKENING OF THE 850MB
THERMAL RIDGE, HIGHS TUESDAY WILL BE A BIT COOLER, DOWN IN THE UPPER
70S TO MID 80S.
LONG TERM
(WEDNESDAY THROUGH MONDAY)
ISSUED AT 1244 AM CDT TUE MAR 10 2026
WEDNESDAY MORNING, MOST OF THE STRONG TO SEVERE THUNDERSTORMS SHOULD
BE EAST OF WEST CENTRAL TEXAS. AN UPPER LEVEL LOW WILL TRACK ACROSS
THE REGION, THEN MOVE EAST OF THE AREA BY LATE AFTERNOON. WITH THE
PASSAGE OF THE LOW, A COLD FRONT WILL DIVE SOUTH ACROSS THE AREA
WEDNESDAY MORNING INTO WEDNESDAY AFTERNOON, USHERING IN COOLER
TEMPERATURES AND GUSTY NORTH WINDS. HIGHS ON WEDNESDAY WILL BE IN
THE LOW TO MID 70S FOR MOST LOCATIONS, WITH UPPER 70S ACROSS THE I-
10 CORRIDOR. A FEW SHOWERS, AND A POSSIBLE THUNDERSTORMS, MAY LINGER
THROUGH EARLY AFTERNOON ACROSS OUR EASTERN COUNTIES ON THE BACKSIDE
OF THE LOW. SURFACE HIGH PRESSURE WILL SETTLE ACROSS THE AREA
THURSDAY MORNING, RESULTING IN LIGHT WINDS AND CLEAR SKIES. THE GOOD
RADIATIONAL COOLING CONDITIONS WILL RESULT IN COOL TEMPERATURES BY
SUNRISE, WITH LOWS IN THE UPPER 30S TO LOWER 40S. PLEASANT
TEMPERATURES ARE FORECAST ON THURSDAY WITH HIGHS IN THE UPPER 50S TO
LOWER 70S.
MUCH WARMER TEMPERATURES WILL RETURN TO THE AREA FRIDAY INTO THE
WEEKEND, WITH HIGHS WELL INTO THE 80S. THE WARMEST DAY LOOKS TO BE
SATURDAY WITH HIGHS IN THE UPPER 80S TO LOWER 90S FOR MOST
LOCATIONS. THE NEXT UPPER LEVEL TROUGH WILL SWING ACROSS THE PLAINS
ON SUNDAY, SENDING A COLD FRONT SOUTH THROUGH THE AREA ON SUNDAY.
THE TIMING OF THE FRONT WILL DETERMINE HOW WARM WE GET ON SUNDAY.
LATEST MODEL GUIDANCE IS INDICATING A FASTER FRONTAL PASSAGE, SO
TEMPERATURES WERE TRENDED DOWN. HIGHS WILL RANGE FROM THE MID TO
UPPER 70S ACROSS THE BIG COUNTRY TO THE LOW TO MID 80S ELSEWHERE. NO
RAIN IS FORECAST WITH THE FRONT. MUCH COOLER TEMPERATURES ARE
FORECAST ON MONDAY WITH HIGHS MAINLY IN THE 60S.
