DISCUSSION
ISSUED AT 250 PM CDT WED SEP 23 2026
THROUGH NEXT TUESDAY...NOTICEABLY DRIER AIR THAT IS "NOT SO HOT"
CONTINUES TO FILTER INTO THE REGION, AND THIS WILL REMAIN ACROSS
THE REGION INTO AT EARLY NEXT WEEK. HIGH PRESSURE ALOFT AND AT THE
SURFACE WILL ALSO ASSERT ITSELF INTO THE REGION THROUGH THE
BEGINNING OF THE WEEKEND. RAIN CHANCES WILL ESSENTIALLY BE NIL
ACROSS THE AREA DURING THIS TIME. HIGH TEMPERATURES EACH DAY WILL
BE A BIT LESS THAN THEY'VE BEEN IN RECENT WEEKS, AS THEY RANGE
FROM THE UPPER 80S TO LOW 90S THURSDAY THROUGH SATURDAY. SOME
GRADUAL WARMING WILL THEN ENSUE SUNDAY THROUGH TUESDAY, AS HIGHS
PEAK IN THE LOW AND MIDDLE 90S. THE RESULT OF THE FRONTAL
BOUNDARY WILL CONTINUE TO SLOWLY SINK SOUTH THROUGH THE FORECAST
AREA TODAY. DURING THE AFTERNOON HOURS TODAY, AS HIGHS WARM INTO
THE MIDDLE 90S ACROSS MAINLY SOUTHERN PORTIONS OF THE CWA, A STRAY
SHOWER OR STORM CAN'T BE RULED OUT IN THE VICINITY OF THIS
BOUNDARY. THE REMAINDER OF THE FORECAST AREA WILL REMAIN DRY AS
HIGHS WARM INTO THE LOW AND MIDDLE 90S. E DRIER AIRMASS ACROSS THE
REGION WILL ESPECIALLY BE FELT DURING THE NIGHT TIME HOURS AS
LOWS FALL INTO THE 60S.
ONCE AGAIN, RAIN CHANCES WILL REMAIN TOUGH TO COME BY DURING MOST OF
THIS FORECAST PERIOD. RIDGING ALOFT WILL WEAKEN ENOUGH ON SUNDAY,
ALLOWING A DISTURBANCE EMBEDDED IN NORTHWEST FLOW TO TRAVERSE THE
CWA. THIS WILL BRING SOME ISOLATED SHOWERS TO THE FORECAST AREA
SUNDAY. THEN LATE MONDAY INTO TUESDAY, A SHORTWAVE DROPPING
SOUTHEAST INTO THE REGION WILL YIELD ANOTHER CHANCE FOR RAIN
ACROSS THE FORECAST AREA TUESDAY INTO TUESDAY NIGHT. A GREATER
CHANCE FOR SHOWERS AND STORMS ASSOCIATED WITH A MORE SIGNIFICANT
FRONTAL SYSTEM COULD IMPACT THE AREA JUST BEYOND THIS FORECAST,
AND THIS WILL BE SOMETHING TO MONITOR FOR AS WE GET CLOSER IN
TIME. /19/EC/
