SKIES HAVE CLEARED OVER THE NORTHWEST HALF OF OUR AREA WHILE PARTLY
TO MOSTLY CLOUDY SKIES REMAIN OVER THE SOUTHEASTERN HALF.
TEMPERATURES EARLY THIS AFTERNOON ARE IN THE MID 70S TO LOWER 80S
WITH DEWPOINTS IN THE 60S. SOME OF THE HI-RES MODELS INDICATE THE
DEVELOPMENT OF SOME STORMS IN THE AREA EAST OF A COLEMAN TO JUNCTION
LINE LATE THIS AFTERNOON AND EVENING. SHOULD THIS OCCUR, THE
ENVIRONMENT (STRONG INSTABILITY AND FAVORABLY STRONG EFFECTIVE BULK
SHEAR) WOULD SUPPORT SEVERE STORMS WITH LARGE TO VERY LARGE HAIL AND
DAMAGING WINDS. THERE IS A VERY LOW THREAT FOR AN ISOLATED TORNADO
(2 PERCENT). LOW CLOUD DEVELOPMENT IS EXPECTED FROM THE SOUTH AND
SOUTHEAST LATE TONIGHT AND EARLY MONDAY MORNING. OVERNIGHT LOWS WILL
BE MOSTLY IN THE MID 60S WHICH IS CLOSE TO 15 DEGREES ABOVE NORMAL.
SOUTHWEST FLOW ALOFT WILL CONTINUE OVER OUR AREA ON MONDAY. THE
DRYLINE WILL MIX EAST INTO WESTERN PART OF THE BIG COUNTRY AND
NORTHWESTERN CONCHO VALLEY BY LATE AFTERNOON. CANNOT RULE OUT THE
POSSIBILITY OF AN ISOLATED STORM OR TWO DEVELOPING ON THE DRYLINE BY
LATE AFTERNOON. IF THIS OCCURS, THE ENVIRONMENT (STRONG INSTABILITY
AND EFFECTIVE BULK SHEAR VALUES 35-45 KNOTS) WOULD BE SUPPORTIVE OF
A SUPERCELL WITH LARGE TO VERY LARGE HAIL AND DAMAGING WINDS THE
MAIN THREATS. MOSTLY CLOUDY SKIES MONDAY MORNING WILL BECOME PARTLY
CLOUDY BY AFTERNOON FOR ALL BUT THE SOUTHEASTERN PART OF OUR AREA.
WITH 850MB THERMAL RIDGE BUILDING TO OUR WEST, TEMPERATURES WILL BE
QUITE WARM IN THE BIG COUNTRY AND CONCHO VALLEY, WHERE HIGHS WILL BE
IN THE MID 80S TO NEAR 90. THE REST OF OUR AREA WILL HAVE HIGHS IN
THE LOWER TO MID 80S.

UPPER LEVEL TROUGH WILL BE SITUATED OVER THE DESERT SOUTHWEST ON
TUESDAY AND WILL GRADUALLY MOVE EAST ACROSS THE SOUTHERN ROCKIES
AND INTO WEST TEXAS BY WEDNESDAY. THE DRYLINE WILL BE WEST OF THE
AREA ON TUESDAY AND THEN MIX EAST INTO WESTERN PORTIONS OF THE
FORECAST AREA WEDNESDAY AFTERNOON. LARGE-SCALE LIFT WILL INCREASE
ACROSS WEST TEXAS TUESDAY AFTERNOON AND EVENING, WITH
THUNDERSTORMS LIKELY DEVELOPING ALONG AND EAST OF THE DRYLINE,
ESPECIALLY DURING THE EVENING HOURS. THE POTENTIAL FOR SEVERE
STORMS WILL EXIST, AS STORMS MOVE EAST INTO THE AREA DURING THE
EVENING/OVERNIGHT PERIOD. THE MAIN HAZARDS WILL BE LARGE TO VERY
LARGE HAIL, DAMAGING WINDS AND ISOLATED TORNADOES. SIMILAR SETUP
ON WEDNESDAY WITH ANOTHER THREAT FOR SEVERE STORMS, AS THE DRYLINE
MIXES INTO WESTERN PORTIONS OF THE AREA BY AFTERNOON. MAINLY DRY
THURSDAY AND FRIDAY, ALTHOUGH ISOLATED STORMS ARE STILL POSSIBLE,
PRIMARILY ACROSS THE BIG COUNTRY.
THE NEXT UPPER TROUGH WILL TRACK ACROSS THE ROCKIES AND INTO THE
PLAINS FRIDAY INTO SATURDAY, WITH AN ASSOCIATED COLD FRONT EXPECTED
TO MOVE SOUTH ACROSS THE AREA ON SATURDAY. FOR NOW, LOW RAIN
CHANCES REMAIN IN THE FORECAST OVER THE WEEKEND, ALONG WITH COOLER
