UPDATE
ISSUED AT 1118 AM CDT MON MAY 5 2025
TEMPERATURES HAVE WARMED QUICKLY ACROSS THE AREA SO FAR THIS
MORNING, BUT INCREASING MID AND HIGH CLOUDS FROM CONVECTION OVER
NORTH TEXAS WILL SPREAD OVER THE AREA AFTER NOON, WHICH SHOULD
SLOW THE RATE OF WARMING. MOST OF THE SHOWERS AND STORMS IN TEXAS
ARE JUST NOW APPROACHING OR CROSS THE INTERSTATE 35 CORRIDOR. I'M
STILL UNCERTAIN ABOUT EASTWARD EXTENT OF THIS ACTIVITY INTO
OUR EAST TEXAS COUNTIES PRIOR TO 00Z THIS EVENING. FOR NOW, I'VE
MAINTAINED THIS AFTERNOON'S POP GRIDS, BUT AN ADDITIONAL UPDATE
MAY BE NEEDED LATER THIS AFTERNOON DEPENDING ON THE PROGRESS OF
THE PRECIP.

KEY MESSAGES
- RAIN RETURNS BY THIS AFTERNOON ACROSS DEEP EAST TEXAS,
CONTINUING EASTWARD OVERNIGHT.
- DANGEROUS FLASH FLOODING WILL BE THE PRIMARY LIFE-THREATENING
HAZARD FROM HEAVY RAIN ON TUESDAY (SEVERE THUNDERSTORMS WILL BE
LIKELY AS WELL).
- TEMPERATURES WILL BE MODERATED BY CLOUDS/RAIN TO NEAR-NORMAL FOR
THIS TIME OF THE YEAR.
EASTERLY SURFACE WINDS WILL RETURN IN EARNEST TODAY AHEAD OF A
WARM FRONTAL BOUNDARY OVER WEST TEXAS AND GENERAL RIDGING OVER THE
EASTERN US. THE APPROACH OF THIS BOUNDARY WILL SET THE STAGE FOR
HEAVY RAINFALL FROM SHOWERS AND THUNDERSTORMS AS PWAT VALUES REACH
2 INCHES (APPROACHING 90TH PERCENTILE FOR THIS TIME OF THE YEAR)
THROUGH TUESDAY. ANY THUNDERSTORMS THAT DEVELOP IN EAST TEXAS
COULD BE SEVERE WITH THE DAMAGING AND LARGE HAIL. WITH ANY
DAMAGING WINDS, TREES WITH WATERLOGGED ROOT SYSTEMS MAY BE MORE
SUSCEPTIBLE TO BEING BLOWN OVER. AN AREAWIDE FLOOD WATCH HAS BEEN
ISSUED AS A RESULT. TEMPERATURE MAXIMUMS/MINIMUMS WILL REMAIN
NEAR OR JUST ABOVE NORMAL (80S AND 60S RESPECTIVELY). /16/
LONG TERM
(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 411 AM CDT MON MAY 5 2025
WRAP-AROUND TROUGHING, IN COMBINATION WITH THE ATTENDANT FRONTAL
BOUNDARY OVER PARTS OF THE GULF COAST, WILL KEEP ACTIVE WEATHER IN
PLACE THROUGH MOST OF THE REST OF THE WEEK. AN ADDITIONAL 1-2
INCHES OF RAINFALL IS LIKELY (ESPECIALLY IN SOUTHERN ZONES) ON TOP
OF WET SOILS THROUGH THURSDAY. DRIER NORTHWESTERLY FLOW IS
EXPECTED TO RETURN BY THIS WEEKEND, KEEPING TEMPERATURES NEAR
NORMAL FOR THIS TIME OF THE YEAR. /16/
AVIATION
