(TONIGHT THROUGH THURSDAY NIGHT)
ISSUED AT 1212 PM CDT WED JUL 2 2025
RADAR DATA CONTINUES TO SHOW SCATTERED SHOWERS ALONG WITH A FEW
THUNDERSTORMS ONGOING ACROSS THE RIO GRANDE PLAINS, SOUTHERN EDWARDS
PLATEAU AND PORTIONS OF THE HILL COUNTRY. IN ADDITION, SOME NEW
CONVECTION IS NOTED OVER THE COASTAL PLAINS INTO PORTIONS OF THE I-35
CORRIDOR. WE DID MAKE SOME MINOR ADJUSTMENTS TO THE FORECAST EARLIER,
WITH THE MAIN CHANGE BEING TO ADD SOME LOW RAIN CHANCES FARTHER EAST
INTO THE REMAINDER OF THE I-35 CORRIDOR AND MOST OF THE COASTAL
PLAINS. SIMILAR TO THE PAST FEW DAYS, WELL ABOVE NORMAL MOISTURE IS
IN PLACE ACROSS THE REGION. A FAIRLY UNIFORM SOUTHEAST FLOW IN THE
LOWEST 400MB SHOULD KEEP ANY CONVECTION MOVING FROM SOUTHEAST TO
NORTHWEST AROUND 30 MPH. AREAS THAT SEE REPEATED SHOWERS AND STORM
MAY PICK UP SOME LOCALLY HEAVY RAINFALL. HOWEVER, ANY RISK FOR THIS
IS LOW AND SHOULD REMAIN VERY LOCALIZED MAINLY ACROSS THE RIO GRANDE
PLAINS, SOUTHERN EDWARDS PLATEAU AND HILL COUNTRY.
MOISTURE LEVELS REMAIN NEARLY IDENTICAL ON THURSDAY AND A FAIR
AMOUNT OF THE HI-RES MODELS SHOW SOME DECREASE IN THE COVERAGE OF
SHOWERS AND STORMS ACROSS THE RIO GRANDE, WITH AN INCREASE IN
COVERAGE FARTHER EAST INTO THE HILL COUNTRY AND I-35 CORRIDOR.
SIMILAR TO TODAY, A FEW SPOTS MAY PICK UP SOME LOCALLY HEAVY RAINFALL
GIVEN THE MOISTURE PROFILE ON FORECAST SOUNDINGS. HIGH TEMPERATURES
ON THURSDAY REMAIN BELOW NORMAL FOR ALL AREAS DUE TO AN INCREASE IN
CLOUD COVER AND RAIN CHANCES.
LONG TERM /FRIDAY THROUGH WEDNESDAY/
(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 1212 PM CDT WED JUL 2 2025
WITH PLENTY OF MOISTURE INTACT AND A WEAK UPPER DISTURBANCE TO OUR
NORTH, WE SHOULD SEE ANOTHER DAY OF ISOLATED TO SCATTERED CONVECTION
MAINLY FOR AREAS WEST OF THE INTERSTATE 35 CORRIDOR ON FRIDAY. CLOUD
COVER AND RAIN CHANCES SHOULD KEEP HIGH TEMPERATURES FOR AREAS WEST
OF I-35 BELOW NORMAL, WITH NEAR NORMAL ELSEWHERE. AS WE HEAD INTO THE
UPCOMING WEEKEND, THE SUBTROPICAL HIGH WILL BUILD ACROSS NORTHERN
MEXICO INTO THE DESERT SOUTHWEST. WE SHOULD SEE A GRADUAL DECREASE IN
MOISTURE LEVELS AND AN INCREASE IN TEMPERATURES THROUGH THE WEEKEND.
FOR NOW, WE WILL KEEP THE FORECAST DRY ALONG WITH NEAR TO ABOVE
NORMAL TEMPERATURES. HOWEVER, WE WILL NEED TO MONITOR PORTIONS OF THE
SOUTHERN EDWARDS PLATEAU AS AT LEAST ONE OF THE MEDIUM RANGE MODELS
DOES SHOW A WEAK DISTURBANCE MOVING IN ON SATURDAY.
THE SUBTROPICAL RIDGE REMAINS CENTERED OVER THE DESERT SOUTHWEST AS
WE HEAD INTO THE MIDDLE OF NEXT WEEK. WE EXPECT TO SEE MOST OF SOUTH
CENTRAL TEXAS REMAIN DRY. THE EXCEPTION WILL BE NEAR THE COASTAL
PLAINS AS SOME AFTERNOON AND EARLY EVENING CONVECTION MAY DEVELOP
ALONG THE SEA BREEZE. TEMPERATURES SHOULD REMAIN NEAR TO SLIGHTLY
ABOVE NORMAL.
