SURFACE ANALYSIS SHOWS YESTERDAY'S COLD FRONT NOW DRAPED ALONG THE
EASTERN SEABOARD TO AN AREA OF LOW PRESSURE IN THE SOUTHWESTERN
GULF, WHILE HIGH PRESSURE IS OVER THE SOUTHERN PLAINS. LINGERING
SHOWER ACTIVITY HAS FINALLY CLEARED OUT OF THE FORECAST AREA, AND
CLOUD COVER IS SLOWLY FOLLOWING SUIT AS A DRIER AIRMASS WORKS ITS
WAY INTO THE REGION. MOSTLY SUNNY SKIES SHOULD ALLOW TEMPERATURES TO
WARM UP TO NEAR 70 DEGREES THROUGH THE NEXT FEW HOURS. SURFACE HIGH
PRESSURE CONTINUES TO SETTLE OVERHEAD TONIGHT INTO TOMORROW,
ALLOWING WINDS TO RELAX AND TEMPERATURES TO FALL INTO THE LOW TO MID
50S.
MOVING INTO THE WORK WEEK, WEAK RIDGING BEGINS TO TAKE SHAPE ALOFT
OVER THE PLAINS, WITH A COUPLE OF DISTURBANCES PASSING OVERHEAD
THROUGH THE MID-WEEK. AT THE SURFACE, LOW PRESSURE LINGERS NEAR THE
SOUTH TX COAST, WITH A SURFACE TROUGH EVENTUALLY DEVELOPING THROUGH
THE MID-WEEK. MONDAY BRINGS ONE MORE DAY OF DRY AND COOLER
CONDITIONS, WITH PWATS BELOW THE 25TH PERCENTILE AND HIGHS IN THE
MID TO UPPER 70S. TUESDAY AND WEDNESDAY BRING AN UPTICK IN MOISTURE
FROM THE S/SW AND THE AFOREMENTIONED SURFACE LOW/TROUGH SHIFTS A
SLUG OF MOISTURE UP THE TX COAST. HIGHER MOISTURE VALUES WILL REMAIN
OVER THE GULF WATERS AND SOUTH TX COAST, BUT PWATS WILL STILL
INCREASE TO ABOVE THE 75TH PERCENTILE ACROSS THE CWA. THE
COMBINATION OF INCREASED MOISTURE AND LIFT PROVIDED BY THE PASSING
UPPER LEVEL DISTURBANCES/NEARBY SURFACE TROUGH WILL BRING ABOUT
INCREASED RAIN CHANCES BOTH TUES AND WED. RAIN CHANCES WILL BE BEST
ACROSS SE TX AND LOWER FOR ACADIANA BOTH DAYS, WITH WED BRINGING THE
BEST CHANCE OF RAIN. IN ADDITION, WPC HAS NOW OUTLINED ALL OF SE TX
AND SW/W LA IN A MARGINAL RISK FOR EXCESSIVE RAINFALL ON WEDNESDAY.
WHILE MOISTURE SURGES, INCREASED CLOUD COVER ASSOCIATED WITH THIS
CONVECTION WILL HOLD TEMPS NEAR SEASONAL NORMS THROUGH THE MIDWEEK.
MODEST RAIN CHANCES (GENERALLY IN THE 20-50% RANGE) LINGER EACH DAY
THROUGH THE LATER HALF OF THE WEEK AND INTO THE WEEKEND AS ELEVATED
MOISTURE PERSISTS OVER THE GULF COAST. THIS RAINFALL LOOKS TO BE A
BIT MORE UNORGANIZED AND LESS WIDESPREAD THAN EARLIER IN THE WEEK,
WHICH WILL ALLOW FOR MORE SUNSHINE AND A WARMING TREND TO COMMENCE.
HIGHS REACH INTO THE LOW TO MID 80S, WHILE LOWS ONLY FALL INTO THE
MID TO UPPER 60S.

STRONG AND GUSTY NE WINDS CONTINUE INTO TONIGHT, WITH A COMBINATION
OF SMALL CRAFT AND EXERCISE CAUTION CONDITIONS EXPECTED. NE WINDS
SHIFT E BY EARLY TOMORROW, REMAINING BREEZY AND OUT OF THE E TO SE
THROUGHOUT THE WEEK. RAIN CHANCES INCREASE AGAIN BY TUESDAY AND PEAK
ON WEDNESDAY AS A DISTURBANCE MEANDERS AROUND THE WESTERN GULF NEAR
THE SOUTH TX COASTLINE. THIS DISTURBANCE WILL START TO FADE BY THE
LATE WEEK, ALLOWING RAIN CHANCES TO COME DOWN, WHILE WINDS REMAIN IN
THE 10-15KTS RANGE.
FIRE WEATHER
ISSUED AT 128 PM CDT SUN APR 19 2026
BREEZY NORTHEAST WINDS IN THE WAKE OF YESTERDAY'S FRONT WILL REMAIN
GUSTY- AROUND 20-25KTS THROUGH THE AFTERNOON, ADVECTING A MUCH DRIER
AIRMASS INTO THE REGION. THIS DRY AIRMASS REMAINS IN PLACE FOR
MONDAY, BUT ANY FIRE CONCERNS WILL DECREASE AS WINDS WILL BECOME
LIGHTER, AROUND 5-10 KT. BY TUESDAY, THE WINDS BEGIN SHIFT TO THE
SOUTHEAST, WHICH WILL INCREASE RH AND CHANCES FOR SUBSEQUENT
SCATTERED SHOWERS OVER THE AREA THAT HELP MITIGATE FIRE WEATHER
CONCERNS THROUGH THE REMAINDER OF THE FORECAST PERIOD.
