NEAR TERM
(REST OF TONIGHT AND SATURDAY)
ISSUED AT 1039 PM CDT FRI SEP 25 2026
DEWPOINTS HAVE REMAINED ABOVE GUIDANCE IN MOST AREAS SO FAR THIS
EVENING. WINDS HAVE BECOME LIGHT IN MOST AREAS. GIVEN LIGHT BUT
PREDOMINATE NNE FLOW OVERNIGHT AROUND 1000 MB, STILL EXPECT DRIER
AIR TO MOVE SOUTHWARD AFTER MIDNIGHT ESPECIALLY. BETWEEN NOW AND
MIDNIGHT, GIVEN THE HIGHER DEWPOINTS IN OBSERVATIONS THAN EXPECTED,
CLEAR SKIES, AND DEWPOINT DEPRESSIONS IN SOME LOCATIONS 0 TO 3
DEGREES, EXPECT SOME PATCHY FOG COULD FORM BEFORE DISSIPATING
AFTER MIDNIGHT WITH THE ADVECTION OF DRIER AIR SOUTHWARD. THE
BEST SHOT OF PATCHY FOG SHOULD BE SOUTH OF THE TENNESSEE RIVER.
AS THE DRIER AIR MOVES SOUTHWARD TOWARDS DAYBREAK, TEMPERATURES
LOOK TO STILL DROP INTO THE LOWER 50S TO MID 50S PRIMARILY.
ANOTHER NICE AND DRY DAY IS EXPECTED ON SATURDAY WITH SOME
SCATTERED AFTERNOON CLOUD COVER DEVELOPING. TEMPERATURES SHOULD BE
SIMILAR REACHING THE LOWER 80S PRIMARILY. LOWS WITH ANOTHER GOOD
RADIATIONAL COOLING SETUP SHOULD DROP INTO THE LOWER TO MID 50S
AGAIN SATURDAY NIGHT. A FEW UPPER 40S MAY BE POSSIBLE.
SHORT TERM
(SATURDAY NIGHT THROUGH MONDAY)
ISSUED AT 1039 PM CDT FRI SEP 25 2026
AS THE STRONG LOW ROTATES OVER THE NORTHEAST CONUS PROVIDING VERY
INCLEMENT WEATHER FOR THAT AREA, IT BRIEFLY WEAKENS THE EASTERN
EDGE OF THE UPPER RIDGE OVER THE AREA. HOWEVER, IMPACTS THIS FAR
SOUTH WILL BE MINIMAL, KEEPING NICE, COOL WEATHER IN THE FORECAST
THROUGH SUNDAY NIGHT. HIGHS AND LOWS ARE NOT EXPECTED TO CHANGE
MUCH.
BY EARLY NEXT WEEK, THE AXIS OF THE UPPER RIDGE STARTS TO SHIFT
EAST TOWARDS THE TENNESSEE AND OHIO VALLEY AREAS. THIS SHOULD
PROVIDE A WARMING TREND FOR THE AREA, WITH HIGHS CLIMBING INTO THE
MID 80S ON MONDAY. LOWS DO NOT LOOK MUCH WARMER WITH GOOD
RADIATIONAL COOLING EXPECTED AGAIN MONDAY NIGHT.
LONG TERM
(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 1039 PM CDT FRI SEP 25 2026
OVERALL, THE PATTERN WILL BE IN TRANSITION THIS PERIOD AFTER A WEAK
TROUGH PUSHES INTO THE SOUTHEAST U.S. TUESDAY, BEING OVERWHELMED BY A
BUILDING RIDGE OVER THE SOUTHWEST ATLANTIC BASIN. THIS BUILDS
INFLUENCE INTO THE SOUTHEAST U.S. WEDNESDAY AND THURSDAY. WHILE IN
THE SOUTHWEST U.S. AND PLAINS, A COMPLEX UPPER LOW AND EVENTUAL REMNANT
HURRICANE POLO EVOLUTION REMAIN UNCERTAIN. FOR OUR AREA, SOUTHERLY
FLOW WILL BE ENHANCED BETWEEN THE RIDGE AND TROUGH, KEEPING MOIST AND
UNSTABLE AIR FLOW NORTHWARD. THIS WILL INTRODUCE LOW CHANCES OF
SHOWERS AND THUNDERSTORMS, PRIMARILY DAYTIME HEATING DRIVEN, DURING
THE LATTER HALF OF NEXT WEEK. TEMPERATURES WILL ALSO BE ON A WARMING
TREND WITH HIGHS IN THE UPPER 80S TO LOWER 90S.
