DISCUSSION
ISSUED AT 349 AM EDT TUE MAR 24 2026
SURFACE HIGH PRESSURE WILL CONTINUE TO DRIFT EAST OVER THE NEXT 24
HOURS, ALLOWING THE ROLLER COASTER OF TEMPERATURES TO START ITS
CLIMB UP THE TRACK WITH SLIGHTLY ABOVE NORMAL TEMPERATURES TODAY
THEN MUCH ABOVE NORMAL FOR WEDNESDAY AND THURSDAY. A WEAK WAVE WILL
DROP SE ACROSS THE AREA WED EVENING TO BRING A SMALL CHANCE FOR
SHOWERS AND MAYBE A STORM OR 2.
THE MAIN FOCUS WILL BE ON THURSDAY AFTERNOON INTO THURSDAY EVENING,
AS THE NEXT TROUGH AND COLD FRONT ARRIVE TO BRING INCREASING CHANCES
FOR SHOWERS AND THUNDERSTORMS. UNLIKE THE PAST COUPLE OF EVENTS, AN
INFLUX OF DEEPER MOISTURE IS EXPECTED FROM THE GULF WITH DEWPOINTS
LIKELY IN THE 60S FOR MANY AREAS BY THURSDAY AFTERNOON. THIS,
COMBINED WITH TEMPERATURES IN THE 70S TO NEAR 80 WILL ALLOW FOR OVER
1000 J/KG OF MUCAPE, BUT SOUNDINGS INDICATE CAPPING IN PLACE UNTIL
00Z POSSIBLY LIMITING MORE WIDESPREAD DEVELOPMENT UNTIL CLOSER TO OR
BEHIND THE FRONT. ANY STORMS THAT MANAGE TO BREAK THE CAP AHEAD OF
THE FRONT WOULD HAVE SUFFICIENT SHEAR TO WORK WITH FOR ALL MODES OF
SEVERE TO BE IN PLAY. SPC DY3 OUTLOOK HAS MOST OF THE AREA IN A
SLIGHT RISK WITH THE INITIAL FOCUS ON A WIND THREAT. WITH PWATS
INCREASING TO OVER AN INCH AND SOME INDICATIONS OF POOLING ALONG THE
FRONT, LOCALLY HEAVY RAIN COULD BE A CONCERN WITH TRAINING OF CELLS.
TEMPERATURES WILL DIP ONCE AGAIN INTO THE 30S AND 40S FRIDAY BEFORE
HEADING BACK INTO THE 50S AND THEN YET ANOTHER SLOW MODERATION INTO
NEXT WEEK.
