NEAR TERM
(TODAY)
ISSUED AT 226 AM CDT THU MAY 28 2026
TODAY WILL FEEL LIKE A RINSE AND REPEAT OF YESTERDAY. STARTING
THIS MORNING OUT WITH LOW CLOUD CEILINGS THAT CAN REDUCE
VISIBILITIES, SO USE CAUTION DURING YOUR MORNING COMMUTE. ONCE
THAT LIFTS, WE WILL BE LEFT WITH PARTLY CLOUDY TO CLOUDY SKIES
AND AFTERNOON HIGH TEMPS IN THE LOW TO MID 80S. THERE WILL BE LOW
TO MEDIUM CHANCES (20-50%) OF DIURNALLY DRIVEN CONVECTION ONCE
AGAIN THIS AFTERNOON. ANCHORED IN THIS MOIST ENVIRONMENT, HEAVY
RAINFALL WILL BE THE PRIMARY CONCERN ALONG WITH LIGHTNING.
SHORT TERM
(THURSDAY NIGHT THROUGH SATURDAY)
ISSUED AT 950 CDT WED MAY 27 2026
THROUGH THE SHORT TERM FORECAST RIDGING OFF THE ATLANTIC COAST
WILL DAMPEN AS HIGH PRESSURE EVOLVES IN THE MIDWEST. THIS WILL DO
LITTLE TO CHANGE OUR LOCAL WEATHER PATTERN. HIGH PRESSURE TO OUR
NORTH WILL KEEP OUR HIGH PWATS AND DEW POINTS IN PLACE THROUGH THE
SHORT TERM. IN TURN, THIS WILL MAINTAIN OUR MEDIUM TO HIGH
AFTERNOON RAIN CHANCES FRIDAY AND SATURDAY. FLOODING CONCERNS WILL
CONTINUE AS ALL SHOWERS AND STORMS WILL BE CAPABLE OF EFFICIENT
RAINFALL PRODUCTION. SHOULD STORMS MOVE SLOWLY OR TRAIN OVER THE
SAME AREA, WE COULD SEE SOME LOCALIZED FLOODING.
LONG TERM
(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 950 PM CDT WED MAY 27 2026
AS HIGH PRESSURE CONTINUES TO SLOWLY EXPAND OVER THE NORTHEAST
ATLANTIC COAST, UPPER RIDGING CENTERED OVER THE EASTERN PLAINS WILL
STALL ANY SIGNIFICANT CHANGE IN AIRMASS UNTIL LIKELY LATE MONDAY OR
TUESDAY. WE WILL MAINTAIN MEDIUM CHANCES FOR RAIN AND THUNDERSTORMS
SUNDAY AND MONDAY WITH THE GREATEST CHANCES DURING PEAK DIURNAL
HEATING HOURS. UPPER TROUGHING PAIRED WITH HIGH PRESSURE OVER THE
NORTHEAST WILL FINALLY BEGIN TO DIG SOUTH TOWARD TUESDAY, BRINGING A
DRIER AIRMASS TO THE AREA AND A BREAK FROM THE WET AND HUMID PATTERN
WE HAVE BEEN IN LATELY. ONLY LOW CHANCE POPS ARE FORECAST ON TUESDAY
WITH THE MAJORITY OF THE AREA EXPECTED TO STAY DRY. TEMPERATURES
WILL STAY CLOSE TO SEASONABLE NORMS DURING THIS PERIOD, TOPPING OUT
IN THE UPPER 70S/LOWER 80S EACH DAY.
AVIATION
(12Z TAFS)
ISSUED AT 554 AM CDT THU MAY 28 2026
VISIBILITIES HAVE FLUCTUATED THIS MORNING AT BOTH TERMINALS WITH
LOW CLOUDS AND THE DEVELOPMENT OF SOME FOG. THIS WILL IMPROVE OVER
THE NEXT FEW HOURS LEAVING US WITH VFR CONDITIONS UNTIL DIURNAL
THUNDERSTORMS DEVELOP AND BRIEFLY PROVIDE MVFR CONDITIONS WHEN
IMPACTING TERMINALS. OTHERWISE, ADDITIONAL CLOUDS WILL START
MOVING BACK IT TOWARDS THE END OF THE TAF PERIOD WITH A LOW CHANCE
OF SHOWERS LIFTING NORTHWARD INTO THE TERMINALS RIGHT BEFORE THE
END OF THE TAF PERIOD. LEFT THOSE OUT FOR THIS TAF ISSUANCE DUE TO
LOW CONFIDENCE IN TIMING.
