NEAR TERM
(REST OF TONIGHT AND MONDAY)
ISSUED AT 934 PM CST SUN DEC 28 2025
ONLY A FEW HOURS OF MILD TEMPERATURES REMAIN AS A STRONG COLD
FRONT IS RAPIDLY APPROACHING THE TENNESSEE VALLEY FROM THE WEST.
A GLANCE AT RADAR INDICATES THAT A NARROW AREA OF RAIN SHOWERS
(AND PERHAPS AN ELEVATED STORM OR TWO) WILL MOVE ACROSS THE AREA
FROM WEST TO EAST DURING A 04-08Z TIMEFRAME ROUGHLY. THIS FAST-
MOVING SYSTEM WON'T PROVIDE MORE THAN 0.25" TO 0.50" OF RAINFALL
BEFORE TAPERING OFF EARLY MONDAY MORNING. THE STRONG PRESSURE
GRADIENT ASSOCIATED WITH THE PASSING UPPER-TROUGH HAS RESULTED IN
SOME GUSTY WESTERLY WINDS THIS EVENING (AND EVENTUALLY
NORTHWEST), WITH SUSTAINED WINDS OF 15-25 MPH, WITH GUSTS TO 35-40
MPH. A WIND ADVISORY IS IN EFFECT FOR THE ENTIRE TENNESSEE VALLEY
UNTIL 6 AM.
GUSTY WINDS WILL CONTINUE THROUGH MUCH OF THE DAY ON MONDAY IN
WAKE OF THE FRONT AS CLOUD COVER QUICKLY DISSIPATES QUICKLY DURING
THE MORNING HOURS. THERE'S NO OTHER WAY TO SAY IT: MONDAY WILL BE
A RAW DAY AND A SHOCK TO THE SYSTEM FOR MANY. WITH GUSTY NW WINDS AND
MUCH COLDER AIR MASS IN PLACE, TEMPERATURES WILL STRUGGLE TO
CLIMB ABOVE THE UPPER 30S LOWER 40S IN MOST LOCATIONS -- WITH WIND
CHILLS BEING EVEN COLDER! THIS WILL BE AROUND 30 DEGREES COLDER
THAN TODAY. MAKE SURE YOU'RE PREPARED FOR THE COLD AS YOU HEAD OUT
THE DOOR TOMORROW TO START THE WORK WEEK.
SHORT TERM
(MONDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 934 PM CST SUN DEC 28 2025
WINDS WILL WEAKEN SIGNIFICANTLY AFTER SUNSET, RESULTING IN A GOOD
SETUP FOR RADIATIONAL COOLING MONDAY NIGHT IN THIS COLD, DRY AIR
MASS. AS A RESULT, TEMPERATURES WILL FALL INTO THE LOWER 20S IN
MOST LOCATIONS -- WITH A FEW READINGS IN THE LOWER TEENS NOT OUT
OF THE QUESTION. LIGHT WINDS COULD DROP WIND CHILL VALUES INTO THE
10-15 DEGREE RANGE. HIGH PRESSURE AT THE SURFACE OVER THE
NORTHERN GULF WILL PROMOTE MOSTLY CLEAR AND DRY CONDITIONS BOTH
TUESDAY AND WEDNESDAY TO CLOSE OUT 2025. HOWEVER, NORTHWESTERLY
FLOW ALOFT WILL PREVAIL THANKS TO A BROAD UPPER LOW OVER THE GREAT
LAKES, REINFORCING THIS MUCH COLDER AIR MASS. AS A RESULT, HIGHS
IN THE LOWER 40S WILL AGAIN BE COMMON ON TUESDAY, BEFORE
MODERATING SOMEWHAT INTO THE UPPER 40S TO AROUND 50 DEGREES BY
WEDNESDAY.
LONG TERM
(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 934 PM CST SUN DEC 28 2025
A DRY AND SEASONABLE NEW YEARS EVE AND NEW YEARS DAY (THURSDAY)
WILL BE ON TAP FOR THE TENNESSEE VALLEY, WITH AN AREA OF HIGH
PRESSURE AT THE SURFACE STILL THE DOMINANT WEATHER FEATURE, WITH
ZONAL FLOW CONTINUING ALOFT. A FAST-MOVING SHORTWAVE WILL BRING
OUR NEXT SHOT OF RAIN FRIDAY AFTERNOON/EVENING INTO FRIDAY NIGHT
(WITH 60-80% CHANCES FOR SHOWERS FORECAST). RIDGING FROM THE WEST
WILL BEGIN TO BUILD IN BY THE WEEKEND, WITH A GRADUAL WARMING
TREND AND FAIR WEATHER TAKING PLACE BOTH SATURDAY AND SUNDAY.
AVIATION
(06Z TAFS)
ISSUED AT 1053 PM CST SUN DEC 28 2025
GUSTY WEST TO NORTHWEST WINDS WILL CONTINUE OVERNIGHT AND INTO THE
MORNING HOURS ON MONDAY. SHRA WILL MOVE INTO THE REGION DURING
THE NEXT 2-3 HOURS JUST AHEAD OF A COLD FRONT, PROMPTING LOW-END
VFR TO MVFR CONDITIONS DUE TO REDUCED VISIBILITIES AND CEILINGS
INTO THE EARLY MORNING HOURS ON MONDAY. LOW CLOUDS WILL LIFT AFTER
SUNRISE, WITH CLEAR CONDITIONS DEVELOPING BY THE LATE MORNING
INTO THE AFTERNOON.
