A WIDE RANGE OF TEMPS CAN BE FOUND ACROSS THE TN VALLEY AS OF 8 PM
AFTER A VERY PLEASANT DAY. CURRENT TEMPS RANGE FROM THE HIGH 70S
IN URBAN AREAS TO MID 60S IN OUR TERRAIN AREAS. DESPITE ANOTHER
NIGHT OF MOSTLY CLEAR SKIES, TEMPS WILL BE A FEW DEGREES WARMER
THAN LAST NIGHT DUE TO A SLIGHT INCREASE IN DEW POINTS. WINDS
AGAIN LOOK TO REMAIN ELEVATED ENOUGH TO SUPPRESS FOG FORMATION.
TOMORROW, THE PATTERN WILL REMAIN LARGELY UNCHANGED WITH HIGH
PRESSURE FROM THE NE REMAINING DOMINANT AT THE SURFACE. THIS WILL
AMOUNT TO MOSTLY CLEAR SKIES, NO RAIN CHANCES, AND SLIGHTLY
MODERATED HIGHS IN THE LOW TO MID 80S.
SHORT TERM

DESPITE SLIGHT CHANGES IN THE OVERALL PATTERN, THE SURFACE
CONDITIONS WILL REMAIN LARGELY UNCHANGED THROUGH THE SHORT TERM
FORECAST. THROUGH THE SHORT TERM, SEVERAL UPPER LEVEL SHORTWAVES
WILL RIPPLE DOWN FROM THE GREAT LAKES THROUGH THE TN VALLEY ALONG
THE BASE OF THE LARGER LONG WAVE TROUGH SITUATED ACROSS THE
EASTERN CONUS. ALOFT, THIS WILL ONLY WORK TO REINFORCE OUR DRY
AIRMASS WITH NW FLOW BEING MAINTAINED. AT THE SURFACE HIGH
PRESSURE FROM THE NE WILL CONTINUE ITS HOLD ON US. HIGH PRESSURE
SEEPING SOUTH WILL LARGELY SUPPRESS MOISTURE TO THE COASTAL AREAS
KEEPING OUR DEW POINTS COMFORTABLY IN THE 50S AND LOW 60S.
SUBSIDENCE FROM SURFACE HIGH PRESSURE WILL WORK TO KEEP SKIES
CLEAR HOWEVER UNDER CLEAR SKIES TEMPS WILL EMBARK UPON A STEADY
WARMING TREND. TEMPS WILL WARM FROM THE 80S ON WEDNESDAY TO LOW TO
MID 90S BY FRIDAY. THE LOWER DEW POINTS WILL KEEP HEAT INDICES
BELOW ANY HEAT PRODUCTS HOWEVER CONDITIONS WILL FEEL NOTICEABLE
HOTTER THAN THE START OF THE WORK WEEK.
LONG TERM
(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 852 PM CDT MON SEP 8 2025
FROM FRIDAY THROUGH SUNDAY, MID LEVEL TROUGHING WILL EXIT OFF THE
NE COAST ALLOWING MID LEVEL HIGH PRESSURE TO PUSH EAST INTO THE
TN VALLEY. BY MONDAY HIGH PRESSURE WILL BE ALIGNED AT THE SURFACE
AND ALOFT. LOCALLY THIS WILL BRING MORE OF THE SAME. SUBSIDENCE
WILL PROMOTE CLEAR SKIES, SURFACE HIGH PRESSURE WILL KEEP HIGH DEW
POINTS REFINED TO THE COAST, AND OUR WARMING TREND WILL CONTINUE.
TEMPS WILL BE IN THE LOW 90S AT THE START OF THE PERIOD WARMING
TO THE MID 90S BY THE START OF THE WORK WEEK. FORTUNATELY NE
SURFACE FLOW WILL KEEP OUR DEW POINTS COMFORTABLY IN THE HIGH 50S
TO LOW 60S LIMITING OUR HUMIDITY DESPITE THE HEAT.
