SHORT TERM
(REST OF TODAY THROUGH MONDAY)
ISSUED AT 1145 AM CDT SUN AUG 23 2026
WATER VAPOR IMAGERY SHOWS A BROAD AREA OF DRIER AIR ALOFT AND
NORTHWESTERLY FLOW ACROSS THE REGION AND WE FINALLY GOT A TASTE
OF COOLER, DRIER AIR THIS MORNING BEHIND THE FRONT THAT MOVED
THROUGH LAST NIGHT. THIS IS A WELCOMED AIR MASS WHICH WILL PROMOTE
CONTINUED STABLE CONDITIONS AND COOLER EVENINGS AND OVERNIGHTS
THROUGH MONDAY AS HIGH PRESSURE MOVES TO OUR NORTH. WE CURRENTLY
DO NOT HAVE ANY MENTIONABLE RAIN CHANCES THROUGH THE SHORT-TERM AS
A RESULT.
LONG TERM
(MONDAY NIGHT THROUGH NEXT SUNDAY)
ISSUED AT 1145 AM CDT SUN AUG 23 2026
MEDIUM-RANGE GUIDANCE AND ENSEMBLES SUGGEST LITTLE CHANGE IN THE
BACKGROUND WEATHER PATTERN THROUGH THE UPCOMING WEEK. GENERALLY
SPEAKING, RIDGING WILL REMAIN OUT WEST WITH A TROUGH ACROSS THE
EAST. HOWEVER, THE TROUGH SHOULD SLOWLY MOVE EAST MID TO LATE WEEK
WHICH WILL ALLOW FOR A BIT OF MOISTURE RETURN FROM THE LOWER
MISSISSIPPI VALLEY. THIS WILL FOSTER SHOWERS AND A FEW
THUNDERSTORMS MID WEEK. BETTER COVERAGE OF CONVECTION IS POSSIBLE
WITH PASSING SHORTWAVES PROGGED DURING THIS TIMEFRAME AND WE'LL
HAVE TO SEE IF WE GET ANY SEVERE WEATHER SINCE WE'LL REMAIN IN
MODEST MID-LEVEL FLOW. TOO EARLY TO TELL RIGHT NOW. OVERALL THE
TEMPERATURE FORECAST IS PRETTY CLOSE TO SEASONAL NORMS MID TO LATE
WEEK AND GUIDANCE IS ON THE DRIER SIDE LATE WEEK INTO NEXT
WEEKEND.
