GOES-EAST TOTAL PRECIPITABLE WATER LOOP SHOWS A SURGE HIGHER
PRECIPITABLE WATER OF AROUND 2 INCHES HAS ARRIVED INTO THE COASTAL
PLAINS. MODEL GUIDANCE INDICATES THIS WILL CONTINUE INLAND INTO THE
INLAND COASTAL PLAINS, BRUSH COUNTRY, AND NEAR SAN ANTONIO THROUGH
THE AFTERNOON AND EVENING. WIDELY SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS HAVE DEVELOPED ACROSS THE COASTAL PLAINS AND WILL
CONTINUE TO SPREAD INLAND INTO THE ABOVE MENTIONED AREAS THROUGH THE
AFTERNOON AND EARLY EVENING, WITH ACTIVITY DIMINISHING AROUND AND
AFTER SUNSET.
THE HIGHER MOISTURE WILL CONTINUE TO SPREAD WESTWARD MONDAY AND
MONDAY NIGHT, WITH A PIECE OF MID LEVEL FORCING BREAKING OFF THE
REMNANTS OF TROPICAL STORM BARRY AND MOVING NORTHWEST, UP THE RIO
GRANDE, MONDAY AND MONDAY NIGHT. THE MOISTURE AND WEAK FORCING WILL
ALLOW FOR WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS MONDAY
AFTERNOON AND EVENING FARTHER WEST INTO THE AREA, CLOSER TO THE RIO
GRANDE AND WINTER GARDEN REGION, WITH ISOLATED COVERAGE OF SHOWERS
FARTHER EAST, WHERE INFLUENCE FROM THE WEAK RIDGE JUST TO THE EAST
AND LIGHT CONCENTRATIONS OF SAHARAN DUST RESIDE.
LONG TERM
(TUESDAY THROUGH SUNDAY)
ISSUED AT 1253 PM CDT SUN JUN 29 2025
MODELS INDICATE AREAS EAST OF I-35 WILL REMAIN GENERALLY UNDER THE
INFLUENCE OF A WEAK MID AND UPPER RIDGE EARLY TO MID WEEK. WEST OF
THE RIDGE, WEAK DISTURBANCES IN THE SOUTHERLY FLOW ALOFT WILL MOVE
OUT OF MEXICO AND INTO THE RIO GRANDE AND SOUTHERN EDWARDS PLATEAU. A
CONTINUED STREAM OF HIGHER PRECIPITABLE WATER AIR OUT OF THE WESTERN
GULF WILL ALSO MOVE INTO THIS REGION. THE HIGHER CHANCES (20-40%)
FOR WIDELY SCATTERED SHOWERS TUESDAY THROUGH FRIDAY WILL BE LOCATED
ACROSS THE RIO GRANDE AND SOUTHERN EDWARDS PLATEAU, WITH ONLY A 10-
20% CHANCE FARTHER EAST. LIGHT CONCENTRATIONS OF SAHARAN DUST MAY
LINGER INTO TUESDAY AND POSSIBLE WEDNESDAY, MAINLY ALONG AND EAST OF
I-35, RESULTING IN SLIGHTLY HAZY CONDITIONS BUT NO SIGNIFICANT
RESTRICTIONS TO VISIBILITIES OR IMPACTS AT THE SURFACE.
AVIATION
(00Z TAFS)
ISSUED AT 651 PM CDT SUN JUN 29 2025
AN INFLUX OF TROPICAL MOISTURE CONTINUES OVER THE AREA, BUT AN
INFUSION OF SAHARAN DUST MONDAY WILL INCREASE FORECAST UNCERTAINTY.
CONVECTIVE ALLOWING MODELS SHOW A FAIR AMOUNT OF SHOWER ACTIVITY
MOVING UP THE RIO GRANDE VALLEY TO POTENTIALLY IMPACT DRT/SAT/SSF,
BUT NOT SO MUCH AT AUS. THE DUST COULD LOWER VSBY TO 6SM ALONG I-35
WHERE THE AIR WILL BE SLIGHTLY MORE STABLE. MIXING LATER IN THE DAY
SHOULD IMPROVE VSBYS SOME WITH MAYBE A LIGHT HAZE. MORNING CLOUDINESS
WILL BE THE LARGEST UNCERTAINTY AS MODELS DIFFER ON WHETHER A LOW CIG
FORMS AT ALL. WILL KEEP WITH THE PERSISTENCE TREND WHICH IS A MORE
CAUTIOUS APPROACH.
