THE TENNESSEE VALLEY SITS UNDERNEATH THE WESTERN EDGE OF AN UPPER
LEVEL TROUGH. COOL AND DRY NNW FLOW HAS MADE FOR A VERY PLEASANT
END TO THE MONTH OF MAY. THE ONLY NOTICEABLE IMPACT TO THE LOCAL
WEATHER IS A HAZY SKY DUE TO SMOKE ALOFT ORIGINATING OUT OF
CANADA. THIS MADE FOR A VERY COLORFUL SUNSET THIS EVENING AND WITH
IT STICKING AROUND THROUGH TOMORROW EXPECT A SIMILARLY COLORFUL
SUNRISE. OUTSIDE OF THE SMOKE, A TRANQUIL EVENING IS IN STORE WITH
OVERNIGHT LOWS DIPPING DOWN INTO THE UPPER 50S TO LOWER 60S.
BY SUNDAY, THE UPPER LEVEL TROUGH BEGINS TO LIFT FURTHER TO THE
NORTHEAST. HOWEVER, THE GENERAL FLOW ACROSS THE SOUTHEAST REMAINS
QUITE THE SAME AS IT WAS ON SATURDAY. THEREFORE, EXPECT NEARLY
SIMILAR CONDITIONS ON SUNDAY WITH HIGHS IN THE LOWER 80S AND SOME
HAZY SKIES DUE TO THE AFOREMENTIONED SMOKE. THE ONE DIFFERENCE
WILL BE IT WILL NOT BE AS BREEZY IN THE AFTERNOON DUE TO THE UPPER
LEVEL LOW LIFTING FURTHER AWAY FROM THE SOUTHEAST. ONE UNCERTAINTY
IN THE FORECAST IS A QUICK MOVING SHORTWAVE WILL DROP SOUTHEAST
THROUGH MS AND LA. WHILE NOT EXPECTING WIDESPREAD PRECIP, THERE IS
A VERY LOW CHANCE OF SOME SHOWERS REACHING OUR TN COUNTIES AND
PERHAPS INTO NORTHERN AL. HOWEVER CONFIDENCE IN THIS OCCURRING IS
QUITE LOW.
SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY)
ISSUED AT 916 PM CDT SAT MAY 31 2025
ANOTHER CALM AND SEASONABLE NIGHT SUNDAY WITH LIGHT WINDS AND
CLEAR SKIES. ONCE AGAIN, OVERNIGHT LOWS DROP DOWN INTO THE UPPER
50S TO LOWER 60S. AS WE START NEXT WEEK, AN UPPER LEVEL RIDGE
BEGINS TO BUILD ACROSS THE SOUTHEAST. SOUTHERLY TO SOUTHWESTERLY
FLOW RETURNS BRINGING BACK A WARMER AND MORE HUMID AIRMASS. THE
GOOD NEWS IS THAT THE DRY PATTERN CONTINUES THROUGH THE END OF THE
SHORT TERM PERIOD. EXPECT TEMPERATURES TO RISE INTO THE MID 80S
ON MONDAY AND THEN UPPER 80S ON TUESDAY. DEWPOINTS WILL ALSO
INCREASE INTO THE LOW TO MID 60S MAKING IT FEEL MORE LIKE SUMMER.
THIS WILL KEEP OVERNIGHT LOWS IN THE MID TO UPPER 60S.
LONG TERM
(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 916 PM CDT SAT MAY 31 2025
MIDWEEK A SFC LOW WILL MOVE INTO THE MIDWEST AND BE SLOWED DOWN BY
A RIDGE OF HIGH PRESSURE THAT SITS OVER THE SOUTHEAST AND MID
ATLANTIC. THIS WILL LEAVE MOST OF WEDNESDAY DRY BUT BREEZY WITH THE
PRESSURE GRADIENT INCREASING. COULD SEE A FEW SHOWERS (LOW CHANCE OF
10-15%) SNEAK INTO THE TN VALLEY WEDNESDAY NIGHT. THE FRONT WILL NOT
MAKE MUCH PROGRESS AND STALL OUT TO OUR NORTHWEST FOR THE LATTER HALF
OF THE WORKWEEK. AS THE HIGH PRESSURE SLOWLY WEAKENS, IT WILL ALLOW FOR
A GREATER COVERAGE OF SHOWERS AND THUNDERSTORMS TO MOVE IN. LOW
CHANCES (20-40%) EXIST FOR THURSDAY/THURSDAY NIGHT WHILE THEY
INCREASE TO MEDIUM CHANCES (40-70%) ON FRIDAY. MODELS CONTINUE TO
SHOW A FEW HUNDRED J/KG OF INSTABILITY AND LOW SHEAR VALUES ON
THURSDAY, HOWEVER VALUES ARE INCREASING ON FRIDAY ALONG WITH THE
PWATS. SO WILL HAVE TO MONITOR THE POTENTIAL FOR STRONG TO SEVERE
STORMS. OTHERWISE, LOOK FOR DAYTIME HIGHS TO BE IN THE UPPER 80S WITH
LOWS AROUND 70.
