SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 1218 AM CDT FRI APR 17 2026
DRY AND MOSTLY CLOUDY CONDITIONS ARE EXPECTED THIS MORNING WITH
CONTINUED SOUTH TO SOUTHEASTERLY WIND OVER THE REGION. AN UPPER
LEVEL TROUGH DEEPENS AND DIGS INTO THE CENTRAL PLAINS TODAY WHICH
PUTS SOUTH CENTRAL TEXAS BETWEEN A SURFACE LOW TO THE NORTHWEST AND
HIGH PRESSURE TO THE EAST. THIS SET-UP WITH ALLOW FOR BREEZY
SOUTHERLY WIND TODAY WITH GUSTS TO AROUND 25 MPH MOST FAVORED IN THE
EASTERN HALF OF THE CWA. WE SHOULD SEE SOME SUNSHINE AS WELL TODAY
AS CLOUDS SCATTER MID TO LATE MORNING LEAVING AFTERNOON HIGHS WARM
IN THE UPPER 80S TO MID 90S.
WIND RELAXES LATE TONIGHT AS A COLD FRONT APPROACHES OUR AREA FROM
THE NORTHWEST, WHICH SHOULD BE RIGHT ON OUR DOORSTEP SOMETIME AROUND
SUNRISE TO MID-MORNING ON SATURDAY. THE FRONT MOVES ACROSS ALL OF
SOUTH CENTRAL TEXAS DURING THE DAYTIME MAKING TEMPERATURES TRICKY
WITH CLOUD COVER AND RAIN CHANCES FORECAST BEHIND THE FRONT GIVEN
ITS GRADUAL SLOPE. MOST GUIDANCE INDICATES AFTERNOON TEMPERATURES TO
BE IN THE 50S AND 60S AND DID TREND COLDER ON SATURDAY THAN THE NBM.
ADDITIONALLY, GUSTY NORTHERLY WIND IS EXPECTED BEHIND THE FRONT
AIDING IN THE COOLER TEMPERATURES WITH SOME GUIDANCE INDICATING
GUSTS AS HIGH AS 40 MPH DIRECTLY BEHIND THE FRONT. RAIN IS MAINLY
EXPECTED BEHIND THE FRONTAL PASSAGE DUE TO OVERRUNNING BUT WITH GOOD
ELEVATED INSTABILITY IN PLACE WE COULD STILL SEE SOME THUNDERSTORM
ACTIVITY WHICH COULD PRODUCE SMALL HAIL. OVERALL RAIN AMOUNTS DON'T
APPEAR TOO IMPRESSIVE WITH LREF GUIDANCE SHOWING ABOUT A 25 PERCENT
CHANCE FOR A HALF INCH OF RAIN ACROSS THE AREA THROUGH SATURDAY
NIGHT.
LONG TERM
(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1218 AM CDT FRI APR 17 2026
RAIN CHANCES CONTINUE SATURDAY NIGHT BUT BEGIN TO SHIFT SOUTH AS
SURFACE HIGH PRESSURE BRIEFLY MOVES OVER THE AREA SUNDAY MORNING
BEFORE MOVING EAST SUNDAY AFTERNOON. THIS WILL LEAVE LOW TO MEDIUM
RAIN CHANCES PRIMARILY IN THE SOUTHERN AND WESTERN-MOST PORTIONS OF
THE AREA SUNDAY DURING THE DAY, WITH MAINLY COOL AND CLOUDY
CONDITIONS IN STORE. BREEZY NORTH TO EAST WIND CONTINUES INTO SUNDAY
MORNING BEFORE EASING SUNDAY AFTERNOON AND EVENING. THOUGH MID-LEVEL
RIDGING BUILDS OVER THE AREA SUNDAY, A DISTURBANCE WITHIN THE
SOUTHWESTERLY FLOW WILL LIKELY GENERATE SHOWERS AND THUNDERSTORMS
WEST OF THE AREA SUNDAY NIGHT WHICH WILL SHIFT EAST ACROSS OUR AREA
INTO TUESDAY. THE CLOUDY AND COOLER CONDITIONS CONTINUE DURING THIS
TIME, THOUGH WIND WILL BE LIGHTER THAN THE WEEKEND.
WE'LL START TO SEE THE RETURN OF SOUTHEASTERLY FLOW TUESDAY WHICH
LOOKS TO CONTINUE FOR THE REST OF THE LONG TERM PERIOD. THIS WILL
BRING A DAY BY DAY WARMING TREND BACK TO THE AREA WITH HIGHS
RETURNING INTO THE 80S MID-WEEK. WEAK MID-LEVEL RIDGING REMAINS OVER
THE AREA MID TO LATE WEEK KEEPING PRECIPITATION CHANCES LOW, BUT
DISTURBANCES ALOFT AND A DRYLINE IN WEST TEXAS KEEP RAIN CHANCES NON-
ZERO.
