UPDATE
ISSUED AT 730 AM CDT SAT OCT 25 2025
WE HAVE CANCELLED THE FLOOD WATCH FOR THE SOUTHERN EDWARDS PLATEAU
AND CENTRAL AND WESTERN HILL COUNTRY. A FLOOD WATCH REMAINS IN
EFFECT, AND WAS EXTENDED INTO THE EVENING AND EXPANDED EAST, FOR
THE NORTHEAST HILL COUNTRY, I-35 CORRIDOR, AND PORTIONS OF THE
U.S. 77 CORRIDOR.
POCKETS OF HEAVY RAINFALL CONTINUE EARLY THIS MORNING IN MEDINA
AND BEXAR COUNTY. THIS SHOULD WANE AND EXIT EAST MID MORNING.
THERE IS THE POTENTIAL THAT THIS SOUTHERN EXTENT OF THE FLOOD
WATCH COULD BE CANCELLED EARLY. HOWEVER, RE-DEVELOPMENT OF
THUNDERSTORMS IS INDICATED LATER THIS AFTERNOON INTO THE EARLY
EVENING HOURS THROUGH PORTIONS OF THE NORTHEAST HILL COUNTRY, I-35
CORRIDOR NORTH OF SAN ANTONIO, AND PORTIONS OF THE U.S. 77
CORRIDOR. SOME OF THESE STORMS COULD DROP A VERY QUICK 1-2 INCHES
WITH ISOLATED HIGHER AMOUNTS. THESE RAINFALL RATES ARE LEADING TO
THE POTENTIAL FOR ISOLATED POCKETS OF FLASH FLOODING THIS
AFTERNOON AND EARLY EVENING.
SHORT TERM
(TODAY THROUGH SUNDAY)
ISSUED AT 141 AM CDT SAT OCT 25 2025
AS ADVERTISED, A LINE OF SHOWERS AND THUNDERSTORMS FORMED EARLIER
AND HAS MOVED OVER THE EDWARDS PLATEAU, HILL COUNTRY, AND I-35
CORRIDOR. THERE IS ALSO A CLUSTER OVER THE DEL RIO AREA INTO THE
EDWARDS PLATEAU. THE LINE WILL CONTINUE MOVING TO THE EAST AND
EXIT TO THE COASTAL PLAINS AND EAST OF US 77 IN THE NEXT COUPLE OF
HOURS WHILE THE CLUSTER MOVES EAST THROUGH THE EARLY MORNING
HOURS. THE MAIN THREATS WILL BE DAMAGING WINDS AND LARGE HAIL, AS
WELL AS LOCALLY HEAVY RAINFALL RATES THAT MAY CAUSE FLASH, SMALL
STREAM, AND URBAN FLOODING. WILL MAINTAIN THE SEVERE THUNDERSTORM
WATCH THROUGH ITS EXPIRATION TIME OF 3 AM CDT.
THE MODELS AND ENSEMBLES SHOW CONTINUE REDEVELOPMENT OF SHOWERS AND
THUNDERSTORMS THROUGH THE MORNING INTO THE AFTERNOON AND EARLY
EVENING. THE ACTIVITY THEN MOVES OFF TO OUR EAST AROUND MIDNIGHT OR
SHORTLY THEREAFTER. THIS REDEVELOPMENT IS DUE TO DESTABILIZATION BY
HEATING AND FORCING BY AN UPPER LEVEL TROUGH, A STRONG JET STREAK,
MID LEVEL IMPULSE, AND A PACIFIC FRONT. FAVORED AREAS ARE THE HILL
COUNTRY TO ALONG AND EAST OF THE I-35 CORRIDOR. MODERATELY STEEP MID
LEVEL LAPSE RATES AND SHEAR INDICATE A POTENTIAL FOR SEVERE STORMS
WITH LARGE TO VERY LARGE HAIL AND DAMAGING WINDS. LOCALLY HEAVY
RAINS ARE POSSIBLE AND MAY CAUSE FLOODING, ESPECIALLY ACROSS AREAS
THAT RECEIVED HEAVY RAIN WITH THE ONGOING ACTIVITY. MARGINAL TO
SLIGHT RISKS CONTINUE TO BE HIGHLIGHTED BY SPC AND WPC FOR SEVERE
STORMS AND HEAVY RAINS, RESPECTIVELY. WILL MAINTAIN THE FLOOD
WATCH THROUGH 1 PM CDT, HOWEVER IT MAY BE RECONFIGURED, EXPANDED,
OR CANCELLED DEPENDING ON LATER DEVELOPMENT.
FAIR SKIES AND WARM TEMPERATURES ARE EXPECTED ON DRY NORTHWESTERLY
FLOW ALOFT ON SUNDAY.
LONG TERM
(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 141 AM CDT SAT OCT 25 2025
A DRY NORTHWESTERLY FLOW ALOFT PREVAILS NEXT WEEK. A DEEPENING UPPER
LEVEL LOW DROPPING SOUTH OVER THE PLAINS TO LOWER MISSISSIPPI VALLEY
BY MID WEEK DRAGS A STRONG COLD FRONT ACROSS OUR AREA ON TUESDAY.
AFTER TEMPERATURES BEING ABOVE TO WELL ABOVE AVERAGE SO FAR THIS
OCTOBER, COLD ADVECTION TAKES THEM BELOW TO WELL BELOW AVERAGE ON
WEDNESDAY TO CLOSE OUT THE MONTH. NO RAIN IS CURRENTLY FORECAST FOR
NEXT WEEK. HOWEVER, SOME MODELS AND ENSEMBLES INDICATE A FEW SHOWERS
AND PERHAPS A THUNDERSTORM OR TWO WITH THE PASSAGE OF THE COLD FRONT
ON TUESDAY.
