DISCUSSION
(THIS EVENING THROUGH NEXT WEDNESDAY)
ISSUED AT 148 PM CDT THU APR 2 2026
A SHORTWAVE TROUGH IS QUICKLY ACCELERATING ACROSS THE GREAT LAKES
REGION THIS EVENING AND OVERNIGHT. LOCALLY, UPSTREAM TROUGHING WILL
LINGER BEHIND THIS FEATURE ACROSS THE SOUTHERN PLAINS. WHILE
ABUTTING HIGH PRESSURE RIDGING ACROSS THE CENTRAL GULF, A MODERATE
PRESSURE GRADIENT WILL REMAIN IN PLACE THROUGH FRIDAY WHICH
FACILITATES A DECENT SOUTHERLY, ONSHORE FLOW. TEMPERATURES WILL
CONTINUE TO CLIMB INTO LOW TO MID 80S FOR MOST LOCATIONS. THERE WILL
BE A SIMILAR COVERAGE OF ISOLATED / SCATTERED SHOWERS AND
THUNDERSTORMS AS THE UPPER LEVEL ATMOSPHERE CONTINUES TO DESTABILIZE
AHEAD A SECONDARY SHORTWAVE TRANSITING THE UPPER MIDWEST AND GREAT
LAKES REGION.
THAT FEATURE IS SET TO MOVE THROUGH SATURDAY NIGHT AND WILL SLOWLY
STRETCH SYNOPTIC TROUGHING AND THE COLD FRONT AS FAR SOUTH AS
NORTHERN MEXICO. GIVEN THE RELATIVELY COOL, DRY CONTINENTAL AIRMASS
BEHIND THIS FRONT WITH THE PRESSURE GRADIENT IN PLACE, FRONTOGENESIS
SHOULD ADD MORE EFFECTIVE CONVECTIVE INSTABILITY IN THE MIX TO
GENERATE WIDESPREAD SHOWERS AND THUNDERSTORMS. BECAUSE OF THE
GREATER COVERAGE AND DURATION OF POTENTIALLY HEAVY RAINFALL, AT
TIMES, THERE IS A MARGINAL RISK FOR EXCESSIVE RAINFALL SATURDAY.
PROVIDED STORMS DO NOT BACK BUILD, WHICH STILL REMAINS A STEADY
POSSIBILITY, MOST EXCESSIVE RAINFALL WOULD RESULT IN COMMON NUISANCE
PONDING ON CITY STREETS OR AREAS WITH SLOW DRAINAGE.
THE FRONT IS EXPECTED TO SLOW OVERNIGHT SATURDAY INTO SUNDAY MORNING
INDICATING MUCH OF THE RAINFALL WILL OCCUR LATE SATURDAY AND THROUGH
THE OVERNIGHT HOURS. ADDITIONALLY, PERIODS OF RAINFALL MAY RETAIN
ACROSS LOWER SETX AND SWLA THROUGH THE MORNING HOURS SUNDAY WHILE
THE COLD FRONT ADVANCES OFFSHORE. AS MENTIONED EARLIER, FAIRLY
STRONG HIGH PRESSURE CONTINENTAL AIRMASS WILL ENCOMPASS THE FORECAST
AREA SUNDAY RESULTING IN WINDS BECOMING NORTHERLY AND BREEZY.
CONDITIONS WILL REMAIN CLOUDY AND COOL THROUGH MONDAY UNTIL HIGH
PRESSURE BEGINS TO BROAD OVER NEW ENGLAND TUESDAY. HOWEVER, WINDS
WILL BE SLOW TO VEER TO THE SOUTHEAST UNTIL WEDNESDAY. A SLOW
REBOUND IN TEMPERATURES WILL OCCUR THROUGH THE MID WEEK TO THE UPPER
70S.

A LIGHT TO MODERATE SOUTHEAST FLOW WILL CONTINUE THROUGH SATURDAY AS
HIGH PRESSURE REMAINS CENTERED WELL TO THE EAST AND LOWER PRESSURE
REMAINS OVER THE PLAINS, ALBEIT WITH A GRADUAL INCREASE AS THE
PRESSURE GRADIENT TIGHTENS SOMEWHAT. A COLD FRONT WILL MOVE THROUGH
SATURDAY NIGHT WITH A STRONG NORTHEAST FLOW LINGERING INTO TUESDAY
AS LOW PRESSURE DEVELOPS NEAR SOUTH TEXAS AND MOVES EAST.
