NEAR TERM
(TONIGHT)
ISSUED AT 227 PM CDT TUE MAY 12 2026
A BEAUTIFUL DAY ACROSS THE TENNESSEE VALLEY, WITH 19Z TEMPERATURES
IN THE UPPER 70S TO LOWER 80S AND JUST SOME SCATTERED CU NOTED ON
SATELLITE IMAGERY. THESE CLOUDS WILL QUICKLY DISSIPATE AFTER
SUNSET AS WINDS RELAX. AS A RESULT, IT WILL BE A GOOD SETUP FOR
RADIATIONAL COOLING IN THIS DRY AIR MASS WITH A CLEAR SKY.
OVERNIGHT LOWS WILL DROP INTO THE LOW TO MID 50S IN MOST
LOCATIONS, WITH SOME UPPER 50S NOTED ACROSS NORTHWEST ALABAMA.
SHORT TERM
(WEDNESDAY THROUGH THURSDAY NIGHT)
ISSUED AT 853 AM CDT TUE MAY 12 2026
THE LAST DAYS OF PLEASANT TEMPERATURES WILL OCCUR OVER THE NEXT
COUPLE OF DAYS AS WE REMAIN IN NORTHWEST FLOW ALOFT, THANKS TO A
BROAD UPPER TROUGH OVER THE GREAT LAKES. HIGH PRESSURE AT THE
SURFACE WILL STILL PROMOTE SUNNY/CLEAR CONDITIONS BOTH DAYS, WITH
A SLIGHTLY WARMER DAY ON TAP FOR WEDNESDAY AS HIGHS IN THE LOW TO
MID 80S WILL BE COMMON (WITH COMFORTABLE RH VALUES). A WEAK
SHORTWAVE WILL BRING A DRY COLD FRONT THROUGH THE AREA WEDNESDAY
EVENING/NIGHT, BRINGING REFRESHING SHOT OF COOL/DRY AIR INTO THE
TENNESSEE VALLEY. HIGHS ON THURSDAY WILL RUN ABOUT 5-10 DEGREES
LOWER THAN WEDNESDAY (MID/UPPER 70S HIGHS) AND OVERNIGHT LOWS
THURSDAY NIGHT WILL DROP INTO THE UPPER 40S TO LOWER 50S (UNDER A
CLEAR SKY).
LONG TERM
(FRIDAY THROUGH MONDAY)
ISSUED AT 1014 PM CDT MON MAY 11 2026
THESE PLEASANTLY COOL TEMPERATURES WILL QUICKLY COME TO AN END AS
TEMPS RISE AS WE HEAD INTO THE WEEKEND AND INTO EARLY NEXT WEEK. AS
WE END THE WEEK, WE WILL HAVE A TROUGH ALONG THE MID ATLANTIC AND
NORTHEAST, ANOTHER TROUGH IN MANITOBA, AND A RIDGE IN BETWEEN.
THIS WILL HELP BOOST OUR HIGHS TO THE LOWER 80S ON FRIDAY.
THIS WEEKEND THE EAST COAST TROUGH WILL MOVE OUT AND THE CANADIAN
ONE WILL RUN OVER THE RIDGE, FLATTENING IT. A FEW DISTURBANCES
RIPPLING THROUGH WILL TRY TO BRING A LOW CHANCE (10-30%) OF SHOWERS
AND A FEW STORMS ON SATURDAY BUT THAT WON'T COOL US DOWN. BETWEEN THE
RIDGE AND THE WAA FROM SOUTHERLY FLOW, HIGHS WILL BE SET IN THE MID
TO UPPER 80S. A NEW TROUGH SLIDING OUT FROM THE UPPER ROCKIES AND
INTO THE NORTHERN PLAINS WILL PUSH THE RIDGE EASTWARD ON SUNDAY AND
MODELS DISAGREE ON THE EVOLUTION OF THIS TROUGH AND THE EFFECT IT HAS
ON THE RIDGE HEADING INTO NEXT WEEK. REGARDLESS, TEMPS WILL BRING
BACK A TASTE OF SUMMER WITH HIGHS AROUND 90 DEGREES ON SUNDAY AND IN
THE LOWER 90S ON MONDAY. REGARDLESS, BE SURE TO BRUSH UP ON YOUR HEAT
SAFETY AND ENSURE THAT NEXT WEEKEND YOU KNOW HOW TO STAY COOL AND
HYDRATED. DON'T FORGET: NEVER LEAVE PEOPLE OR PETS IN VEHICLES!
