DISCUSSION
ISSUED AT 130 PM CDT TUE MAR 31 2026
TONIGHT THROUGH NEXT MONDAY...CONVECTION THAT'S DEVELOPED ACROSS THE
FORECAST AREA THIS AFTERNOON WILL GRADUALLY DISSIPATE THIS EVENING
AS DAYTIME HEATING WANES. LOW STRATUS WILL AGAIN DEVELOP ACROSS THE
AREA DURING THE OVERNIGHT HOURS INTO EARLY WEDNESDAY MORNING, ALONG
WITH SOME PATCHY FOG OVER MAINLY SOUTHERN PORTIONS OF THE AREA. SOME
ISOLATED SHOWERS WILL ALSO BE POSSIBLE AROUND DAY BREAK WEDNESDAY,
AS LOWS FALL INTO THE LOW AND MIDDLE 60S.
WARM CONDITIONS WILL PERSIST ACROSS THE FORECAST AREA INTO THE
UPCOMING WEEKEND WITH HIGHS IN THE 80S AND LOWS IN THE 60S.
DIURNALLY DRIVEN CONVECTION WILL AGAIN BE POSSIBLE WEDNESDAY
AFTERNOON. HOWEVER, BETTER AND MORE WIDESPREAD RAIN CHANCES WILL
EXIST ACROSS THE FORECAST AREA THURSDAY INTO FRIDAY NIGHT, AND AGAIN
SATURDAY INTO EARLY SUNDAY MORNING. NEITHER OF THESE DAYS LOOK TO
BE COMPLETE WASHOUTS AT THE MOMENT, BUT BETTER CHANCES FOR SHOWERS
AND STORMS EXIST AT THESE TIMES DUE TO SHORTWAVES TRYING TO MOVE
THROUGH THE REGION.
AT PRESENT, THE SYSTEM THURSDAY NIGHT WILL STRUGGLE TO MAKE HEADWAY
THROUGH THE FORECAST AREA AS HIGH PRESSURE HOLDS FIRMLY IN PLACE.
WHILE THIS WILL AGAIN BRING AN INCREASE IN RAIN CHANCES, THE
BOUNDARY ASSOCIATED WITH THE SHORTWAVE WILL HANG UP JUST TO OUR
WEST, AND ESSENTIALLY ERODE. HOWEVER OVER THE WEEKEND, A STRONGER
SHORTWAVE WILL SUCCESSFULLY SWING THROUGH THE REGION DRAGGING A COLD
FRONT INTO AND THROUGH THE CWA LATE SATURDAY NIGHT INTO EARLY SUNDAY
MORNING. THIS WILL BRING SHOWERS AND STORMS TO THE ENTIRE FORECAST
AREA, ALONG WITH A COOL DOWN BOTH SUNDAY AND MONDAY AS COLDER DRIER
AIR ADVECTS INTO THE REGION. /19/
