SHORT TERM
(THIS EVENING THROUGH SUNDAY)
ISSUED AT 214 PM CDT SAT MAR 29 2025
THE DRYLINE IS CURRENTLY MOVING INTO OUR WESTERN COUNTIES AND WILL
CONTINUE TO PROGRESS EASTWARD THIS EVENING. BEHIND THIS BOUNDARY,
DEWPOINTS HAVE DROPPED INTO THE 20S AND 30S. THESE DRY
CONDITIONS, COMBINED WITH BREEZY WINDS, WILL LEAD TO ELEVATED
FIRE WEATHER CONDITIONS FOR OUR WESTERN COUNTIES THIS AFTERNOON. A
SHORTWAVE WILL APPROACH THE AREA THIS EVENING, MOVING OVER NORTH
TEXAS TONIGHT. THE DRYLINE WILL STALL OVER OUR AREA THIS EVENING,
BEFORE RETREATING SLIGHTLY WESTWARD OVERNIGHT. THIS WILL KEEP THE
DRYLINE OVER OUR AREA, PROVIDING A POTENTIAL TRIGGER FOR
CONVECTION FOR MUCH OF THE OVERNIGHT PERIOD. THE SET UP FOR SEVERE
STORMS THIS EVENING AND OVERNIGHT IS VERY CONDITIONAL. WE WILL
HAVE A DECENT CAP AT THE SURFACE, WHICH WILL ACT TO INHIBIT
THUNDERSTORM DEVELOPMENT. HOWEVER, WITH THE DRYLINE OVER THE AREA
AND THE LIFT FROM THE SHORTWAVE, WE COULD SEE A FEW STORMS
INITIATE DESPITE THE CAP IN PLACE. IF A STORM CAN GET GOING, THE
ENVIRONMENT WILL BE CONDUCIVE FOR THE FORMATION OF LARGE HAIL AND
DAMAGING WINDS. SPC HAS UPGRADED BROWN COUNTY AND PORTIONS OF
SURROUNDING COUNTIES TO A SLIGHT RISK FOR THE POTENTIAL FOR LARGE
HAIL OVER 2 INCHES. OVERALL, THE COVERAGE OF STORMS WILL LIKELY BE
LOW, BUT THE STORMS THAT DO DEVELOP WILL HAVE A DECENT CHANCE OF
GOING SEVERE. THE HIGHEST CHANCE FOR SEEING STORMS WILL BE IN THE
HEARTLAND AND NORTHWEST HILL COUNTRY, WITH THE LOWEST CHANCES IN
THE WESTERN BIG COUNTRY. STORMS COULD START AS EARLY AS 8 PM AND
END AS LATE AS 9 AM TOMORROW, BUT THE MOST LIKELY TIMING OF
STORMS FOR OUR AREA WILL BE BETWEEN MIDNIGHT AND 6 AM.
THE DRYLINE WILL MOVE OFF TO THE EAST IN THE LATE MORNING/EARLY
AFTERNOON TOMORROW. BEHIND IT WE'LL SEE WEST/NORTHWEST WINDS AROUND
10 TO 20 MPH. A COLD FRONT WILL APPROACH OUR AREA FROM THE NORTH
TOMORROW. THE COLD FRONT SHOULD ENTER THE NORTHERN BIG COUNTRY IN
THE EARLY AFTERNOON, WITH VERY LITTLE SOUTHWARD PROGRESSION FOR
THE REST OF THE DAY SUNDAY.
LONG TERM
(SUNDAY NIGHT THROUGH NEXT SATURDAY)
ISSUED AT 201 PM CDT SAT MAR 29 2025
A RATHER ACTIVE PATTERN IS IN STORE FOR MUCH OF NEXT WEEK AS
MULTIPLE SYSTEMS WILL AFFECT THE SOUTHERN PLAINS IN SOME WAY. THE
WEEK SHOULD START OFF WITH THE INTRUSION OF A SOUTHWARD-MOVING COLD
FRONT SUNDAY NIGHT THROUGH MONDAY. THIS FRONT IS NOT EXPECTED TO
GENERATE ANY PRECIPITATION AND SHOULD NOT HAVE MUCH IMPACT OTHER
THAN LOWER TEMPERATURES CLOSER TO SEASONAL NORMALS. THIS AIRMASS
WILL BE SHORT-LIVED, HOWEVER, AS A BROAD UPPER-LEVEL TROUGH IS
PROGGED TO SET UP OVER THE WESTERN US FOR TUESDAY AND WEDNESDAY.
STRONG SOUTHERLY WINDS WILL OCCUR TUESDAY AS A SURFACE LOW DEVELOPS
IN THE LEE OF THE ROCKIES AND THIS SHOULD PUSH HIGH TEMPERATURES
BACK INTO THE UPPER 80S. MODELS SHOW A 30-40KT LOW-LEVEL JET WITH
50KT MID-LEVEL WINDS OVER THE SOUTHERN HIGH PLAINS ON TUESDAY. GIVEN
THESE CONDITIONS, THERE IS A LOW TO MEDIUM CHANCE FOR 25 TO 35 MPH
WINDS OCCURRING TUESDAY AFTERNOON. BY TUESDAY NIGHT INTO WEDNESDAY,
THE LOW PRESSURE SYSTEM WILL PUSH A COLD FRONT INTO THE REGION FROM
THE NORTHWEST. THIS COULD GENERATE CHANCES FOR SHOWERS AND
THUNDERSTORMS FROM THE CONCHO VALLEY SOUTHEASTWARD ALTHOUGH THE
FAVORABLE DYNAMICS FOR STRONG TO SEVERE THUNDERSTORMS APPEAR MORE
LIKELY OVER THE MID-MISSISSIPPI VALLEY.
FOR THE LATTER PART OF NEXT WEEK, MODELS ARE IN FAIRLY GOOD
AGREEMENT ON THIS COLD FRONT BECOMING STATIONARY OVER THE SOUTHERN
PLAINS, ESPECIALLY OVER CENTRAL TEXAS. MEANWHILE, MODEL CONSENSUS
SHOWS THE BROAD UPPER TROUGH SHOULD DIG FURTHER SOUTH AND ENTRENCH
ITSELF ACROSS THE WESTERN US, WHICH WOULD PLACE WEST CENTRAL TEXAS
IN SOUTHWESTERLY FLOW ALOFT. THIS, COMBINED WITH A STEADY FLOW OF
GULF MOISTURE AND LIFT FROM THE STALLED BOUNDARY, COULD RESULT IN
MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS FOR THE REGION FRIDAY
THROUGH SATURDAY. AS ALWAYS, MODEL SOLUTIONS CAN AND WILL LIKELY
CHANGE SIGNIFICANTLY OVER THE NEXT FEW DAYS, SO THIS WILL MONITORED
CLOSELY THROUGHOUT THE WEEK.
AVIATION
(00Z TAFS)
ISSUED AT 648 PM CDT SAT MAR 29 2025
ISOLATED TO SCATTERED THUNDERSTORMS ARE POSSIBLE THIS EVENING INTO
THE OVERNIGHT HOURS, AND HAVE PROB30 GROUPS IN OUR TAFS TO ADDRESS
THIS POSSIBILITY. GIVEN THE ENVIRONMENT, THERE IS A CONDITIONAL
RISK OF STRONG WINDS AND HAIL, SHOULD STORMS DEVELOP. PATCHY LOW
CLOUD DEVELOPMENT OVER OUR SOUTHEASTERN COUNTIES IS EXPECTED LATE
TONIGHT AND EARLY SUNDAY MORNING, WITH MVFR CEILINGS. THIS WOULD
MOST LIKELY AFFECT THE KJCT TAF SITE, BUT MAY EXPAND AS FAR WEST
AS KSOA AND AS FAR NORTH AS KBBD. WINDS SUNDAY MORNING WILL
SHIFT TO THE WEST-NORTHWEST AT 8-12 KNOTS.
FIRE WEATHER
ISSUED AT 214 PM CDT SAT MAR 29 2025
THE DRYLINE IS MOVING INTO OUR WESTERN COUNTIES EARLY THIS
AFTERNOON. BEHIND THE DRYLINE, HUMIDITY VALUES ARE IN THE SINGLE
DIGITS TO LOW TEENS AND WINDS ARE AROUND 10 TO 20 MPH. AN RFW IS
IN EFFECT FOR THE WESTERN BIG COUNTRY AND NORTHERN CONCHO VALLEY
THROUGH 10 PM TODAY FOR VERY DRY CONDITIONS COMBINED WITH BREEZY
WINDS. THE DRYLINE WILL CONTINUE EAST OUT OF OUR AREA TOMORROW,
BRINGING WIDESPREAD MINIMUM HUMIDITIES IN THE TEENS TO SINGLE
DIGITS. WINDS WILL BE A BIT WEAKER TOMORROW, WHICH WILL HELP LIMIT
FIRE WEATHER POTENTIAL. HOWEVER, WITH HOW DRY THE FUELS ARE AND
HOW LOW THE HUMIDITIES WILL BE, FIRE WEATHER CONDITIONS WILL BE
ELEVATED AGAIN TOMORROW.
