SHORT TERM
(TODAY THROUGH SUNDAY)
ISSUED AT 110 AM CDT SAT JUL 5 2025
A MID LEVEL MCV AND UNSEASONABLY MOIST AIRMASS (05/00Z SOUNDINGS
SHOWED 2.1 INCH PWS AT DEL RIO AND CORPUS CHRISTI WHICH ARE IN THE
90 PERCENTILE PLUS) REMAIN IN PLACE OVER OUR AREA. THIS FEATURE AND
MOIST AIRMASS LINGER OVER OUR AREA THROUGH THIS WEEKEND. FORCING BY
THIS FEATURE ALONG WITH HEATING WILL GENERATE ROUNDS OF SHOWERS AND
ISOLATED THUNDERSTORMS. STORM MOTION VECTORS SHOW SLOW MOVING AND
REPEAT ACTIVITY TO ENHANCE EFFICIENT WARM RAIN PROCESSES. AS A
RESULT, LOCALLY HEAVY RAINS WITH AMOUNTS OF GENERALLY 2 TO 4 INCHES
ARE EXPECTED WITH ISOLATED AMOUNTS UP TO 10 INCHES POSSIBLE. THESE
AMOUNTS WILL AGGRAVATE ONGOING FLOODING AND LIKELY CREATE NEW
FLOODING AS SOILS ARE SATURATED MAKING RUNOFF MORE RAPID. THE
HEAVIEST RAINS WILL BE OVER THE HILL COUNTRY TO ALONG AND EAST OF
THE I-35 CORRIDOR TODAY. HAVE ISSUED A FLOOD WATCH THROUGH 7 PM CDT
FOR THOSE AREAS. MOST MODELS SHOW THE RAINS SHIFTING TO OUR WESTERN
AREAS ON SUNDAY. THERE IS A POTENTIAL FOR ANOTHER FLOOD WATCH FOR
SUNDAY. THE CLOUDS AND RAIN AREAS WILL CONSPIRE TO KEEP DAYTIME
TEMPERATURES BELOW TO WELL BELOW EARLY JULY AVERAGES.
LONG TERM
(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 110 AM CDT SAT JUL 5 2025
THE MID LEVEL FEATURE REMAINS IN CLOSE PROXIMITY TO GENERATE SHOWERS
AND ISOLATED THUNDERSTORMS ON MONDAY WITH A POSSIBILITY OF LOCALLY
HEAVY DOWNPOURS. HAVE EXPANDED THE SLIGHT CHANCES TO MOST OF OUR AREA
FOR MONDAY. MOST MODELS/ENSEMBLES SHOW THE SUBTROPICAL RIDGE SHOVING
THE MID LEVEL FEATURE AWAY FROM OUR AREA WHILE BRINGING INCREASED
SUBSIDENCE AND DECREASING MOISTURE LEVELS TO KEEP RAINFALL OUT OF THE
FORECAST FOR THE REMAINDER OF THIS COMING WEEK. HOWEVER, AN INVERTED
TROUGH MOVING IN FROM THE EAST MAY BRING CHANCES OF SHOWERS AND
ISOLATED THUNDERSTORMS ON TUESDAY AND WEDNESDAY PER GFS. LATER
FORECASTS MAY INTRODUCE RAIN CHANCES SHOULD THIS BECOME A TREND.
INCREASED SUNSHINE LEADS TO TEMPERATURES WARMING TO NEAR TO SLIGHTLY
ABOVE MID JULY AVERAGES.
