KEY MESSAGES
- LINGERING SHOWERS AND THUNDERSTORMS WILL MOVE OFF TO EAST TODAY.
- WARMER AND DRIER WEATHER THURSDAY AND FRIDAY.

SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 115 AM CDT WED MAY 27 2026
THERE IS A DEEP UPPER LOW OVER NORTHERN CA/NV WITH BROAD CYCLONIC
FLOW OVER TEXAS. A LINE OF THUNDERSTORMS IS MOVING THROUGH THE
EASTERN PART OF THE CWA. THE BLENDED MODEL SOLUTION SHOWS LOW TO
MODERATE RAIN CHANCES ACROSS OUR EASTERN COUNTIES TODAY AND THIS
EVENING. THE UPPER SHORTWAVE WILL MOVE AWAY TO THE EAST AND A WEAK
RIDGE WILL TAKE ITS PLACE. THIS WILL BRING DRY WEATHER FOR TONIGHT
AND MOST OF THE AREA THURSDAY. SOUTHEASTERLY FLOW IN THE LOW LEVELS
WILL KEEP PW ABOVE 1.25" AND THERE MAY BE ENOUGH LIFT TO GENERATE
ISOLATED SHOWERS OR THUNDERSTORMS OVER THE I-35 CORRIDOR AND COASTAL
PLAINS, BUT WE THINK MOST PLACES WILL STAY DRY.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 115 AM CDT WED MAY 27 2026
THE UPPER LOW OVER THE WEST WILL BEGIN TO LIFT OUT TOWARD THE
NORTHEAST FRIDAY AND BRING SOUTHWESTERLY FLOW OVER TX FOR THE
WEEKEND. THE LOW LEVEL FLOW WILL CONTINUE TO BE FROM THE SOUTHEAST.
THIS WILL BRING A WARM, MOIST AIRMASS OVER OUR CWA. A SERIES OF
UPPER LEVEL SHORTWAVES WILL BRING CHANCES FOR SHOWERS AND
THUNDERSTORMS EACH AFTERNOON SATURDAY THROUGH TUESDAY. AT THIS TIME
NOTHING LOOKS WELL ORGANIZED, STRONG, OR HEAVY RAIN PRODUCING. WE
WILL SEE WHAT LATER FORECASTS SHOW.
AVIATION
(12Z TAFS)
ISSUED AT 622 AM CDT WED MAY 27 2026
CONVECTION PRIMARILY OVER THE COASTAL PLAINS MAY AID IN A BRIEF
SHOWER NEAR KSSF THIS MORNING. FOR NOW, WILL KEEP VCSH IN THE
FORECAST FOR THE NEXT FEW HOURS. A RUMBLE OF THUNDER ALSO
POSSIBLE, BUT NOT CONFIDENT ENOUGH TO MENTION IN THE FORECAST AT
THIS TIME. OTHERWISE, SOME LOW CLOUDS ARE BEGINNING TO DEVELOP
BENEATH THE THICK MID AND UPPER LEVEL CLOUDS OVER THE REGION.
WHILE MOST CIGS SHOULD BE MVFR, WE DID OPT FOR SOME IFR AT KSAT.
VFR SHOULD RETURN BY LATE MORNING AS MID AND UPPER LEVEL CLOUDS
SLOWLY CLEAR.
