KEY MESSAGES
UPDATED AT 1016 PM CDT SUN SEP 27 2026
- A WARMING TREND WILL TAKE PLACE THIS WEEK WITH INCREASING
HUMIDITY YIELDING A MODERATE HEAT RISK (LEVEL 2/4) IN SOME
AREAS WEDNESDAY THROUGH SATURDAY.
- LOW TO MEDIUM CHANCES OF THUNDERSTORMS WILL RETURN TO THE
FORECAST LATE THIS WEEK INTO THE WEEKEND.
NEAR TERM
(REST OF TONIGHT AND MONDAY)
ISSUED AT 1016 PM CDT SUN SEP 27 2026
HIGH PRESSURE AND NORTHERLY WINDS WILL CONTINUE TO ENFORCE A DRY
AND COOL AIRMASS OVERNIGHT. DEWPOINTS IN THE 40S, LIGHT WINDS,
AND CLEAR SKIES WILL ALLOW FOR GOOD RADIATIONAL COOLING.
OVERNIGHT LOWS WILL FALL TO THE LOW TO MID 50S WITH NO FOG
EXPECTED.
WHILE LARGE SCALE SUBSIDENCE CONTINUES OVER THE MAJORITY OF THE
EASTERN CONUS, UPPER RIDGING WILL SLOWLY BEGIN TO EXPAND EAST OVER
THE PLAINS. THIS PUTS US IN A BIT OF A TRANSITION ZONE BETWEEN AN
UPPER LOW OFF THE NORTHERN ATLANTIC COAST AND THE RIDGING TO OUR
WEST, AND WILL ALLOW FOR NEAR SEASONAL TEMPERATURES AND CONTINUED
DRY WEATHER. HIGHS WILL TOP OUT IN THE LOW TO MIDDLE 80S TOMORROW
AFTERNOON WHILE LOWER HUMIDITY MAKES THE AIR FEEL A LOT MORE
COMFORTABLE THAN WE HAVE SEEN IN RECENT WEEKS. WITH RH VALUES
DROPPING BELOW 30% TOMORROW AFTERNOON, THE RISK FOR WILDFIRES WILL
INCREASE. WHILE LIGHT WINDS WILL MITIGATE LARGER FIRE CONCERNS,
PLEASE BE RESPONSIBLE WITH OPEN OUTDOOR FLAMES!
SHORT TERM
(MONDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1016 PM CDT SUN SEP 27 2026
THE AFOREMENTIONED RIDGE WILL BEGIN TO CENTER MORE OVER THE MS
RIVER VALLEY DURING THE SHORT TERM PERIOD WHILE SFC HIGH PRESSURE
SLOWLY PUSHES TOWARD THE ATLANTIC COAST BUT KEEPS THE HIGHER
MOISTURE AT BAY UNTIL LATE WEDNESDAY. TEMPS WILL WARM INTO THE
UPPER 80S ON TUESDAY THEN REACH THE 90 DEGREE MARK IN SEVERAL
LOCATIONS WEDNESDAY. WE WILL MAINTAIN A DRY FORECAST WITH THE MAIN
CONCERN BEING THE HEAT. AFTERNOON HEAT INDICES WILL TOP OUT NEAR
90 DEGREES ON WEDNESDAY SO WE WILL REMAIN BELOW HEAT ADVISORY
CRITERIA, BUT THESE TEMPERATURES WILL STILL POSE A RISK FOR HEAT
RELATED ILLNESS FOR THOSE WITHOUT PROPER HYDRATION OR THOSE DOING
STRENUOUS ACTIVITIES OUTDOORS WITHOUT A BREAK. REMEMBER TO NEVER
LEAVE PEOPLE OR PETS UNATTENDED IN VEHICLES!
LONG TERM
(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 1016 PM CDT SUN SEP 27 2026
THURSDAY WILL BRING ONE MORE HOTTER THAN NORMAL DAY BEFORE A
POTENTIALLY WETTER PATTERN DEVELOPS INTO THE WEEKEND. AN UPPER RIDGE
WILL BE HOLDING TIGHT OVER THE SOUTHEAST U.S. THURSDAY INTO FRIDAY AS
A SLUGGISH UPPER LOW SITS OVER THE SOUTHERN HIGH PLAINS. COMPLICATING
THIS PATTERN WILL BE A TUTT OVER THE CENTRAL GULF OF AMERICA THAT
WILL BE LIFTED NORTHWARD ON SATURDAY INTO SUNDAY ACROSS THE GULF
STATES. THIS WILL PRODUCE A STOUT SOUTHERLY TROPICAL FLOW INTO THE
MID SOUTH AND TN VALLEY, YIELDING INCREASING RAIN AND THUNDERSTORMS
OVER A WIDE AREA. ANOTHER FEATURE THAT WILL HELP THIS REGIME WILL BE
A WEDGE FRONT THAT WILL BE DROPPING SOUTHWEST THROUGH THE CAROLINAS
INTO GA AND PERHAPS FAR NORTHEAST AL, PROVIDING ANOTHER ISENTROPIC
LIFTING SOURCE. THE UPPER LOW FINALLY BECOMES AN OPEN WAVE ON SUNDAY
LIFTING INTO THE OH VALLEY AND ABSORBING THE TUTT INTO THE FLOW
ACROSS THE TN VALLEY AND EVENTUALLY OH VALLEY. THUS LOW TO MEDIUM
CHANCES OF RAIN AND THUNDERSTORMS EXIST STARTING THURSDAY AND FRIDAY,
AND INCREASING SATURDAY AND SUNDAY. WITH THE TROPICAL FLOW,
TEMPERATURES WILL BE HELD IN THE UPPER 70S TO LOWER 80S BY THE
WEEKEND, WITH DEW POINTS IN THE UPPER 60S TO LOWER 70S. IT IS TOO
EARLY TO SPECIFY THE EXCESSIVE RAINFALL RISK, BUT IT WILL CERTAINLY
BE MONITORED THROUGH THE WEEK.
