DISCUSSION
ISSUED AT 202 PM CDT MON APR 22 2024
THROUGH TOMORROW:
CALM AND COOL WEATHER IS EXPECTED TO CONTINUE FOR THE REMAINDER OF
THE DAY THROUGH TOMORROW AFTERNOON. A SURFACE HIGH IS EXPECTED TO
CONTINUE TRACKING EASTWARDS INTO THE CWA, BRINGING COOL,
NORTHEASTERLY FLOW INTO THE REGION. THIS WILL ALLOW FOR BELOW NORMAL
TEMPERATURES THROUGH THE REMAINDER OF TODAY INTO TONIGHT. HIGHS
WILL TOP OUT IN THE UPPER 60S TO NEAR 70S, WHICH IS NEARLY 10-15
DEGREES BELOW AVERAGE FOR THE LATTER HALF OF APRIL. OVERNIGHT LOWS
LOOK TO DIP INTO THE LOWER 40S. SOME AREAS IN THE NORTH MAY DROP
INTO THE UPPER 30S, WHILE SOME AREAS IN THE SOUTHEAST MAY
OVERACHIEVE WITH EVAPORATIONAL COOLING AS THE HIGH MIGRATES EAST
OVERNIGHT.
TOMORROW, DRY CONDITIONS WILL CONTINUE AS THE HIGH PRESSURE SHIFTS
CLOSER TO THE SOUTHEAST REGION , WHICH WILL ALLOW FOR SOUTHERLY FLOW
TO INCREASE FROM THE SOUTHWEST. THIS WILL ENABLE MOISTURE TO SNEAK
BACK INTO THE REGION AND TEMPERATURES TO INCREASE ONCE AGAIN.
TOMORROW'S HIGHS LOOK TO INCREASE INTO THE LOWER TO UPPER 70S ACROSS
THE REGION. /AJ/
TUESDAY NIGHT THROUGH SUNDAY NIGHT:
SURFACE HIGH PRESSURE AND DRY CONDITIONS WILL PREVAIL TUESDAY
NIGHT, WITH WARMER OVERNIGHT LOWS MAINLY IN THE 50S. A SHORT WAVE
WILL PUSH A WEAK FRONTAL BOUNDARY INTO THE AREA EARLY ON
WEDNESDAY, BUT CURRENTLY IT MAINLY LOOKS DRY, BUT A COUPLE OF
ISOLATED SHOWERS WILL BE POSSIBLE IN THE NORTH ON WEDNESDAY. THE
FRONTAL BOUNDARY WILL CONTINUE TO EXTEND ACROSS THE NORTHERN
PORTIONS OF THE AREA WEDNESDAY INTO WEDNESDAY NIGHT. ANOTHER
STRONGER SHORT WAVE WILL MOVE ACROSS THE NORTH THURSDAY INTO
THURSDAY EVENING, AND THIS MAY KICK OFF A FEW SHOWERS/STORMS
MAINLY NORTH OF I-20 THURSDAY MORNING INTO THE AFTERNOON HOURS.
UPPER RIDGING WILL STRENGTHEN OVER THE AREA ON FRIDAY AND CONTINUE
INTO SATURDAY. A SERIES OF SHORT WAVES WILL MOVE FROM NORTHEAST
TEXAS INTO ARKANSAS OVER THE WEEKEND, BUT THE ECMWF KEEPS THE BULK
OF THE PRECIPITATION TO OUR WEST THROUGH SUNDAY NIGHT. SHOWERS
AND STORMS MAY CLIP THE DELTA ON SATURDAY AND WE COULD SEE A
LITTLE MORE ACTIVITY ON SUNDAY AND SUNDAY NIGHT, BUT THE LATEST
RUNS ARE BECOMING DRIER FOR SUNDAY. HIGHS OVER THE WEEKEND WILL BE
IN THE LOW TO MID 80S, WITH OVERNIGHT LOWS IN THE 60S. /15/
