DISCUSSION
ISSUED AT 100 AM CST TUE DEC 2 2025
OUR SYSTEM WILL EFFECTIVELY COMPLETE ITS SWEEP EARLY THIS MORNING AS
THE SURFACE REFLECTED LOW SHOOTS EAST AND THE DEFORMATION ZONE
PHASED WITH THE BROADER WARM SECTOR OVERRUNNING PCPN SOON FOLLOWS
ITS DEPARTURE. SO FAR, IT LOOKS LIKE A GOOD SWATH OF 1-2"
OCCURRED/IS OCCURRING WITHIN THE MORE HEAVILY BANDED PCPN, WITH
LESSER AMOUNTS OUTSIDE OF THAT...ESP NORTH AND WEST. SURFACE TEMPS
ARE ALL NOW AT FREEZING OR BELOW, SO EVEN AS SNOW MELT HAS OCCURRED,
STILL SLUSHY ROADS MAY ALSO HAVE SOME ICY SLICK PATCHES DEVELOP AT
TIMES AS WELL...ESPECIALLY BRIDGES/OVERPASSES AND THE LIKE. AND
EVEN WITH SOME AFTERNOON SUNSHINE, TEMPS WILL STRUGGLE TO GET
MUCH ABOVE FREEZING TODAY, WITH HIGHS ONLY IN THE 30S
EVERYWHERE. IT WILL ESSENTIALLY BE A 'HOW TO DEAL WITH WHAT'S
FALLEN' START TO THE DAY AS THE PRECIPITATING ASPECT OF THE
EVENT, FOR ALL PRACTICAL PURPOSES, LOOKS LIKE IT WILL BE DONE
BY 10-11Z, PERHAPS EARLIER WITH CURRENT TRENDING.
AFTER A 1021 MB SURFACE HIGH RIDGES ACROSS THE FA AND TN VALLEY
LATER TODAY AND TONIGHT, ANOTHER HIGH ABOUT 10 MB STRONGER COMES IN
AND HELPS BLAST A REINFORCING SURGE OF ARCTIC COLD AIR ACROSS THE FA
WEDNESDAY NIGHT-THURSDAY. SO AFTER A COOL NIGHT TONIGHT WITH AROUND
20 DEGREE LOWS, WE RECOVER INTO THE 40S WEDNESDAY AS THE FIRST HIGH
SHIFTS EAST, BEFORE PLUNGING AGAIN INTO THE 20S WEDNESDAY NIGHT,
WITH SOME UPPER TEENS IN OUR NORTHERN REACHES; NORTH WINDS HOLD
CLOSE TO 10 MPH, DROPPING WIND CHILLS INTO THE SINGLE DIGITS IN OUR
NORTHWEST COUNTIES ON OUR CWA BORDERS FOR PARTS OF SEMO/SWIL. THE
COLD STICKS AROUND THRU THE DAY THURSDAY WITH HIGHS IN THE 20S
NORTH, AND STRUGGLING TO TOP THE FREEZING MARK SOUTH. AND EVEN WITH
SOME AIR MASS MODIFICATION WITH TIME, BELOW NORMAL TEMPS MORE
WINTER-LIKE WITH 30S/40S FOR HIGHS AND TEENS/20S FOR LOWS HOLDS
RIGHT ON THRU THE WEEKEND. THERE ARE SOME GLANCING BLOWS FOR
POPS IN THE SLIGHT CHANCE RANGE BUT IT'S GENERALLY A DRY PERIOD
SAVE FOR THESE SPOTTY CHANCES EARLY WEEKEND, LATE WEEKEND, AND
EARLY NEXT WEEK.
AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
ISSUED AT 100 AM CST TUE DEC 2 2025
AFTER LIGHT SNOW WINDS DOWN, MVFR TO POSSIBLY AT TIMES IFR CIGS
SHOULD LINGER INTO AND PERHAPS THROUGH MUCH OF THE DAY,
PARTICULARLY FURTHER EAST. TIME/HEIGHT CROSS SECTIONS REVEAL A
LINGERING RIBBON OF LOW LAYER RH THAT EXPIRES AROUND 00Z SO
PRESUMABLY WE SHOULD SEE TERMINALS SCATTER THEIR BASES BY THEN,
PERHAPS EARLIER IN THE WEST.
