UPDATED AT 1218 PM CDT WED MAY 27 2026
- MEDIUM TO HIGH CHANCES FOR SHOWERS AND SCATTERED THUNDERSTORMS

SHORT TERM
(REST OF TODAY THROUGH THURSDAY)
ISSUED AT 1130 AM CDT WED MAY 27 2026
MOIST AIR REMAINS IN PLACE ACROSS THE REGION WITH A VERY SLUGGISH
WEATHER PATTERN THAT HAS BROUGHT NUMEROUS SHOWERS SINCE LAST
WEDNESDAY. THE COVERAGE OF SHOWERS AND STORMS WILL BE GENERALLY
SCATTERED (MEDIUM HIT AND MISS COVERAGE) TODAY. THERE WILL BE
ENOUGH DIURNAL INSTABILITY FOR A COUPLE OF STRONG STORMS WITH
HEAVY DOWNPOURS AND GUSTY WINDS, BUT WE ARE NOT LOOKING FOR ANY
ORGANIZED STORMS OR WIDESPREAD SEVERE THREAT. THE COVERAGE OF
SHOWERS AND STORMS WILL BE LOWER FOR OUR NORTHEAST HALF ON
THURSDAY AS A BACKDOOR FRONT DIPS INTO THE AREA WITH SLIGHTLY
DRIER AIR. SHOWERS AND STORMS WILL MOSTLY DIE OFF AT NIGHT, BUT
THAT WILL SET THE STAGE FOR AREAS OF DENSE FOG.
LONG TERM
(THURSDAY NIGHT THROUGH NEXT WEDNESDAY)
ISSUED AT 1130 AM CDT WED MAY 27 2026
THE SLUGGISH OMEGA BLOCK PATTERN WILL STAY WITH US GOING INTO THE
WEEKEND. WE WILL KEEP THE HUMID CONDITIONS AS A COUPLE OF WAVES
WITH DEEP MOISTURE GRADUALLY PIVOT ACROSS THE AREA. THIS WILL
INCREASE RAIN COVERAGE AGAIN AREA-WIDE FOR LATE FRIDAY INTO
SATURDAY. HIGH PW VALUES SUGGEST POTENTIAL FOR SOME MORE LOCAL
HEAVY DOWNPOURS FOR AT LEAST THE FIRST HALF OF THE WEEKEND.
SCATTERED SHOWER CHANCES LINGER INTO SUNDAY, BUT WE WILL BEGIN TO
FEEL THE BEGINNING OF A PATTERN CHANGE AS THE TROUGH OVER THE
EAST COAST DEEPENS AND FORCES DRY NORTH FLOW INTO TN. DRY
CONDITIONS WILL TAKE HOLD AS WE GO INTO THE NEXT WORK WEEK. WE
WILL ENJOY SOME DEEP BLUE SKIES AGAIN. TEMPERATURES WILL BE NEAR
NORMAL LEVELS, EXCEPT SLIGHTLY COOLER THAN NORMAL AT NIGHT.
HUMIDITY WILL DROP OFF TO COMFORTABLE LEVELS. HEADING INTO LATE
NEXT WEEK, WE WILL HAVE GRADUALLY INCREASING TEMPERATURES AS WE
MOVE INTO A MORE TYPICAL EARLY SUMMER PATTERN.
