CLOUD SHIELD SINKING SOUTHWARD IS CURRENTLY GIVING WAY TO
FLURRIES ACROSS THE TN VALLEY. THIS WILL PERSIST THROUGH THIS
MORNING BEFORE THE CLOUD DECK SCATTERS OUT. BREEZY NORTHERLY WINDS
WITH GUSTS 15-20KTS CONTINUE AT THIS HOUR AND IS CREATING
DANGEROUS WIND CHILLS. THUS, A COLD WEATHER ADVISORY REMAINS IN

AND A SCARF TO STAY WARM. ALSO, CHECK ON OTHERS AND YOUR PETS TO

THE STRONG SFC LOW OFF THE MID ATLANTIC COAST WILL LIFT NORTHWARD
UP THE COAST TODAY, SPREADING WINTER WEATHER ALL ALONG THE
COASTLINE. IN RETURN, A SFC HIGH WILL SLIDE THROUGH THE SOUTHERN
PLAINS AND TOWARDS THE GULF COAST AND INTO THE SOUTHEAST. THIS
WILL HELP TO FINALLY RELAX THE PRESSURE GRADIENT THAT HAS KEPT
GUSTY WINDS IN PLACE ACROSS THE TN VALLEY. ALOFT, NORTHWESTERLY
FLOW WILL SEND A CLIPPER INTO THE REGION AND FORECAST SOUNDINGS
SHOW MID LEVEL CLOUDS WILL RETURN. WAS HOPING TO HAVE MORE
SUNSHINE IN PLACE TO GIVE TEMPS A BOOST, AS ONLY SOME OF US WILL
GET ABOVE FREEZING THIS AFTERNOON. ELEVATED LOCATIONS HAVE THE

AFTER OVERNIGHT LOWS IN THE UPPER TEENS TO LOWER 20S, MONDAY WILL
SEE YET MORE IMPROVEMENT IN TEMPERATURES. NORTHWEST FLOW FROM
8H-5H WILL OCCUR IN ADVANCE OF A RIDGE AXIS OVER THE SOUTH CENTRAL
U.S. 8H TEMPERATURES WILL WARM INTO THE 0-4C RANGE OVER THE TN
VALLEY. SURFACE HIGH TEMPERATURES WILL REACH THE UPPER 40S TO
LOWER 50S AS A RESULT (LOWER 40S ATOP THE CUMBERLAND PLATEAU). THE
RIDGE AXES SHIFT EAST MONDAY NIGHT INTO THE TUESDAY, FOLLOWED
QUICKLY BY A SOUTHERN STREAM WAVE ALONG THE GULF COAST AND A
NORTHERN STREAM CLIPPER WAVE DROPPING QUICKLY THROUGH THE LOWER
MO VALLEY AND OZARK PLATEAU TUESDAY AFTERNOON. THE RESULTING
MULTI-WAVE SURFACE CYCLOGENESIS TAKES PLACE OVER THE SOUTHERN
PLAINS AND OZARKS, WHICH SHOULD MERGE ACROSS THE MID SOUTH
TUESDAY AFTERNOON. A 40-50KT 8H JET WILL COEXIST WITH A
THERMAL/MOIST AXIS ALONG AND AHEAD OF THE LOW AND ATTENDANT COLD

LONG TERM
(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 813 PM CST SAT JAN 31 2026
ON WEDNESDAY A COLD FRONT WILL BE PUSHING SOUTHEASTWARD THROUGH
PORTIONS OF AL AND INTO GA BRINGING AN END TO THE LIGHT RAIN FROM
OVERNIGHT. WITH AN UPPER LEVEL TROUGH DIGGING INTO THE SOUTHEAST
DURING THE MIDDLE OF THE WEEK, WE REMAIN ON THE COOLER SIDE WITH
AFTERNOON HIGHS IN THE LOWER 40S BOTH WEDNESDAY AND THURSDAY.
OVERNIGHT LOWS WILL BE CHILLY IN THE LOWER 20S, ESPECIALLY WEDNESDAY
NIGHT WHEN WINDS GUSTING 15-20 MPH AT TIMES BRINGING WIND CHILLS DOWN
INTO THE LOWER TEENS. HOWEVER, BY FRIDAY THIS TROUGH WILL LIFT TO
THE NORTHEAST KEEPING BOTH THE COLD AIR AND THE PRECIP WELL TO OUR
NORTH. WEAK RIDGING WILL SLOWLY BUILD INTO THE TENNESSEE VALLEY ON
FRIDAY AND SATURDAY, BUT NORTHWEST FLOW ALOFT WILL LIMIT ANY MASSIVE
WARMUP. THAT BEING SAID, AFTERNOON HIGHS FRIDAY AND SATURDAY RETURN
TO THE UPPER 40S TO LOWER 50S, WHICH IS NEAR CLIMATOLOGICAL NORMALS
FOR THIS TIME OF YEAR.
