KEY MESSAGES
UPDATED AT 1015 PM CDT SUN OCT 18 2026
- COOL TEMPERATURES WILL PERSIST TONIGHT BEFORE A SLIGHT WARMING
TREND TAKES SHAPE FROM EARLY TO MIDWEEK.
NEAR TERM
(REST OF TONIGHT AND MONDAY)
ISSUED AT 1015 PM CDT SUN OCT 18 2026
THE TENNESSEE VALLEY WILL CONTINUE TO BE UNDER THE INFLUENCE OF
SUBSIDENCE FROM SURFACE HIGH PRESSURE AND UPPER RIDGING CENTERED
OVER THE SOUTHERN PLAINS. ALTHOUGH, A CUTOFF LOW LOOKS TO REMAIN
FAIRLY STATIONARY OFF THE COAST OF VIRGINIA AND NORTH CAROLINA.
OVERALL, THE DRY, COOL WEATHER WILL PERSIST OVERNIGHT TONIGHT AND
THROUGH THE DAY ON MONDAY. CLEAR SKIES WILL HELP AID TEMPERATURES
TO FALL INTO THE LOWER TO MID 40S LATE TONIGHT INTO MONDAY
MORNING. FOG IS NOT ANTICIPATED DUE TO LARGE DEW POINT
DEPRESSIONS. MAKE SURE TO GRAB AT LEAST A LIGHT JACKET ON YOUR WAY
OUT THE DOOR!
EVEN WITH DEW POINTS DROPPING INTO THE 30S (AND PERHAPS EVEN
LOWER IF SOME HI-RES GUIDANCE IS CORRECT), WINDS ARE EXPECTED TO
BE LIGHT. THUS, WHILE THESE DRY CONDITIONS WARRANT AT LEAST
CAUTION WHEN BURNING, THERE ARE NO ELEVATED FIRE WEATHER CONCERNS
AT THIS TIME. OTHERWISE, HIGHS WILL TOP OUT IN THE UPPER 60S TO
LOWER 70S. ENJOY THE PLEASANT WEATHER!
SHORT TERM
(MONDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1015 PM CDT SUN OCT 18 2026
UPPER RIDGING WILL CONTINUE TO DOMINATE THE CENTRAL PORTION OF
THE COUNTRY THROUGH MIDWEEK. EVEN WITH THE AFOREMENTIONED LOW OFF
THE EASTERN SEABOARD, THIS FEATURE LOOKS TO REMAIN GENERALLY
STATIONARY. THIS WILL CONTINUE TO LET SUBSIDENCE WIN OUT THANKS TO
SURFACE HIGH PRESSURE OVER MUCH OF THE EASTERN CONUS AND THE
UPPER RIDGING. THIS WILL RESULT IN CONTINUED DRY WEATHER (NO RAIN)
BUT ALSO A SLIGHT WARMING TREND THROUGH WEDNESDAY. EXPECT LOWS
GENERALLY IN THE MID 40S BY TUESDAY NIGHT AND HIGHS REACHING THE
MID TO UPPER 70S BY WEDNESDAY. THIS TEMPERATURE TREND LOOKS TO
THEN EXTEND INTO THE LONG TERM AS WELL (SEE BELOW).
LONG TERM
(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 1015 PM CDT SUN OCT 18 2026
THE UPPER RIDGE CENTERED JUST TO OUR WEST APPEARS TO BECOME
BETTER AMPLIFIED TOWARD THE LATER HALF OF THE WEEK KEEPING ABOVE
NORMAL TEMPERATURES IN PLACE ACROSS THE GREAT PLAINS AND MUCH OF
THE SOUTHEAST. HIGH PRESSURE AND LARGE SCALE SUBSIDENCE WILL
CONTINUE TO PROMOTE DRY WEATHER SO MUCH SO THAT EVEN CLOUD COVER
WILL BE HARD TO COME BY UNTIL AT LEAST LATE IN THE WEEKEND. HIGHS
WILL REACH THE MID TO UPPER 70S EACH AFTERNOON, PERHAPS EVEN
REACHING THE 80 DEGREE MARK IN SOME LOCATIONS. CLEAR SKIES AND
CALM OVERNIGHT CONDITIONS WILL ALLOW FOR GOOD DIURNAL COOLING,
WITH LOWS IN THE 40S EACH NIGHT. LONG TERM GUIDANCE BECOMES A BIT
MORE UNCLEAR REGARDING THE UPPER LEVEL PATTERN TOWARD THE END OF
THE WEEKEND, SO WE WILL CONTINUE TO FOCUS ON THE ABOVE-NORMAL
DAYTIME TEMPERATURES WHILE WE MONITOR TRENDS FOR ANY POTENTIAL
FRONTS EARLY NEXT WEEK.
