..NEW AVIATION
DISCUSSION
ISSUED AT 322 AM CDT SUN APR 27 2025
TODAY THROUGH SATURDAY...RIDGING ALOFT WILL FLATTEN ACROSS THE
REGION TODAY, AS A WEAK DISTURBANCE EXITS THE MID-SOUTH REGION.
THIS DISTURBANCE HAS BEEN RESPONSIBLE FOR THE CONVECTION THAT'S
FESTERED ACROSS NORTHWEST PORTIONS OF THE DELTA REGION OVERNIGHT.
AS THIS DISTURBANCE MOVES FURTHER EAST, THIS CONVECTION WILL
GRADUALLY EXIT AND EVENTUALLY FIZZLE OUT. HOWEVER, A WEAK FRONTAL
BOUNDARY OVER THE AREA, COMBINED WITH AFTERNOON HEATING AND ANY
OUTFLOW BOUNDARIES LINGERING ACROSS THE AREA, WILL RESULT IN THE
DEVELOPMENT OF ISOLATED TO SCATTERED SHOWERS AND STORMS ACROSS
OTHER PORTIONS OF THE FORECAST AREA LATER TODAY. THIS ACTIVITY
WILL BEGIN DISSIPATING DURING THE LATE AFTERNOON AND EARLY EVENING
HOURS AS HEATING BEGINS TO WANE. OTHERWISE, LOOK FOR CONTINUED
HUMID CONDITIONS AS HIGHS RANGE FROM THE MIDDLE 80S TO AROUND 90
TODAY, WITH LOWS TONIGHT IN THE MID AND UPPER 60S.
RIDGING ALOFT WILL AGAIN INCREASE ACROSS THE LOWER MISSISSIPPI RIVER
VALLEY THROUGH MID-WEEK. THIS, WHILE HIGH PRESSURE AT THE SURFACE
WEDGES ITSELF INTO THE FORECAST AREA FROM THE EAST. AFTERNOON RAIN
CHANCES WILL BE TOUGHER TO COME BY AS A RESULT, BUT TOASTY AFTERNOON
HIGHS CAN BE EXPECTED AS THEY WARM IN THE MID 80S TO LOWER 90S EACH
DAY THROUGH WEDNESDAY. LOWS MONDAY NIGHT THROUGH WEDNESDAY NIGHT
WILL RANGE FROM THE MID 60S TO AROUND 70.
CHANCES FOR SHOWERS AND STORMS RETURN TO THE FORECAST LATE
WEDNESDAY, CONTINUE THURSDAY INTO THURSDAY NIGHT, AND FINALLY INTO
FRIDAY. ANOTHER TROUGH WILL LIFT NORTHEAST FROM THE SOUTHERN PLAINS
TOWARD THE OHIO RIVER VALLEY OVERNIGHT WEDNESDAY THROUGH THURSDAY
NIGHT. THIS WILL SEND A COLD FRONT EAST INTO THE CWA DURING THIS
TIMEFRAME. WIDESPREAD SHOWER AND SCATTERED THUNDERSTORMS WILL BE
POSSIBLE ACROSS THE AREA, PARTICULARLY THURSDAY INTO THURSDAY NIGHT.
CONFIDENCE IN ANY SEVERE CONVECTION CURRENTLY REMAINS LOW. MUCH OF
THIS STEMS FROM THE CURRENT ADVERTISED SEVERE PARAMETERS BEING OUT
OF PHASE AS THE SYSTEM MOVES THROUGH. THAT SAID, THIS WILL CONTINUE
TO BE MONITORED IN FUTURE FORECASTS.
THE FRONT PUSHES THROUGH THE AREA FRIDAY, WITH RAIN CHANCES ENDING
BY FRIDAY NIGHT. QUIET WEATHER IS CURRENTLY FORECAST OVER THE AREA
INTO THE START OF NEXT WEEKEND. LOOK FOR HIGHS FRIDAY INTO SATURDAY
IN THE UPPER 70S TO MIDDLE 80S AND LOWS FRIDAY AND SATURDAY NIGHT
FROM THE UPPER 50S TO LOWER 60S. /19/
