DISCUSSION
(THIS EVENING THROUGH NEXT TUESDAY)
ISSUED AT 1232 PM CDT WED APR 15 2026
HIGH PRESSURE BOTH AT THE SURFACE AND ALOFT CONTINUE TO
DOMINATE THE WEATHER PATTERN ACROSS THE SOUTHEASTERN U.S. TODAY. A
FEW, LIGHT STREAMER SHOWERS HAVE BEEN DEVELOPING ACROSS SOUTHEAST
TEXAS AND WESTERN LOUISIANA WHERE THE RIDGING IS A BIT WEAKER AND
DEEPER MOISTURE EXISTS. THESE HAVE NOT AMOUNTED TO MORE THAN JUST A
BRIEF PERIOD OF DRIZZLE AND THIS ISN'T EXPECTED TO CHANGE THROUGH
THE AFTERNOON. BREEZY SOUTHERLY FLOW WILL MAINTAIN WARM AND HUMID
CONDITIONS ACROSS THE REGION THROUGH SATURDAY WITH AFTERNOON HIGHS
IN THE MID TO UPPER 80S AND OVERNIGHT LOWS IN THE MID TO UPPER 60S.
A COLD FRONT WILL MOVE THROUGH THE REGION SATURDAY NIGHT INTO EARLY
SUNDAY MORNING ACCOMPANIED BY A BROKEN SWATH OF SHOWERS AND
THUNDERSTORMS. A NARROW SWATH OF DEEP MOISTURE ALONG AND AHEAD OF
THE FRONT WILL SUPPORT PERIODS OF HEAVY RAINFALL. WPC HAS INTRODUCED
A MARGINAL RISK OF EXCESSIVE RAINFALL ROUGHLY ALONG AND NORTH OF THE
HWY 190 CORRIDOR FOR THE POSSIBILITY OF NUISANCE FLOODING FROM HIGH
RAINFALL RATES. STORM TOTALS ARE STILL EXPECTED TO RANGE BETWEEN A
QUARTER AND THREE QUARTERS OF AN INCH WHICH WONT BE ENOUGH TO PUT A
SIGNIFICANT DENT IN THE ONGOING DROUGHT, BUT EVERY LITTLE BIT HELPS.
COOLER, DRIER AND MUCH MORE PLEASANT AIR WILL ADVECT INTO THE REGION
IN THE WAKE OF THE FRONTAL PASSAGE SUNDAY WITH HIGHS SUNDAY
AFTERNOON IN THE LOW TO MID 70S. A COUPLE OF CHILLY NIGHTS ARE
EXPECTED MONDAY AND TUESDAY MORNINGS WITH LOWS IN THE LOW TO MID
50S. WINDS WILL TURN BACK OUT OF THE SOUTH TUESDAY AFTERNOON
INITIALIZING A GRADUAL WARMUP THROUGH THE SECOND HALF OF NEXT WEEK.

14Z WITH VFR CONDITIONS TO PREVAIL THEREAFTER.
