DISCUSSION
ISSUED AT 115 PM CST MON DEC 1 2025
RADAR SHOWS TWO AREAS OF PRECIP OVER THE CWA, ONE OVER JEFFERSON
AND PERRY COUNTIES IN ILLINOIS WHERE LIGHT SNOW/SLEET IS BEING
REPORTED AND A SMALLER MORE CONVECTIVE LOOKING AREA OVER
PERRYVILLE TO POPLAR BLUFF WHERE LIGHT SLEET AND SNOW ARE ALSO
BEING REPORTED. THESE ARE ASSOCIATED WITH THE LEADING EDGE OF
STRONGER LOW-LEVEL WARM AIR ADVECTION, BUT SHOULD BE RELATIVELY
SHORT LIVED BEFORE THE BROADER ASCENT ARRIVES BY 4-6 PM.
SATELLITE/OBS/SHORT-TERM GUIDANCE ARE STARTING TO LINK IN ON
WAA RELATED LIFT OVERSPREADING THE AREA LATE THIS AFTERNOON
WITH PRECIP ACCOMPANYING IT, A LITTLE FASTER THAN ORIGINALLY
THOUGHT. SURFACE TEMPERATURES ARE ABOVE FREEZING OVER MOST OF
WESTERN KENTUCKY BUT THE WET-BULB TEMPERATURE IS CLOSE TO
FREEZING, SO THE ADDITION OF THE EXTRA LIFT/MOISTURE SHOULD
RESULT IN TEMPERATURES FALLING NEAR FREEZING AFTER SUNSET. THIS
SHOULD RESULT IN RAIN CHANGING OVER TO SLEET/FREEZING RAIN IN
THE EVENING OVER WKY WITH AREAS TO THE NORTHWEST A LITTLE MORE
SNOW FOCUSED. THE JET-LEVEL DCVA ASCENT MOVES IN BY 9-10 PM OR
SO AND MERGES WITH THE WAA ASCENT BEFORE SWEEPING ALL THE
PRECIP OUT OF THE AREA ALONG AND AHEAD OF A COLD FRONT.
I THINK IN THE SOUTHERN PENNYRILE IF TEMPS GET LOW ENOUGH, AND
IT LOOKS LIKE THEY WILL, WE COULD SEE UP TO 0.10" OF ICE
ACCRETION. OVER THE NORTHWESTERN PART OF THE CWA THE DCVA ASCENT
SHOULD RESULT IN 1 TO 2 INCHES OF SNOW. IN BETWEEN I AM
CONCERNED THAT DRY SLOTTING WILL LIMIT PRECIP AMOUNTS HOWEVER
THE LOW LEVEL RH IS HIGH ENOUGH FOR FREEZING DRIZZLE REGARDLESS.
THIS COUPLED WITH PERIODS OF FREEZING RAIN, SLEET AND LIGHT
SNOW WOULD BE CAPABLE OF CREATING QUITE A TRAVEL MESS TONIGHT
AND EARLY TOMORROW. AFTER COLLABORATING WITH NEIGHBORS THIS
MORNING WENT WITH A MORE AGGRESSIVE CWA-WIDE WINTER WEATHER
ADVISORY AS FREEZING DRIZZLE CAN BE SIGNIFICANTLY IMPACTFUL TO
TRAVEL, EVEN IN SMALL AMOUNTS.
A COLD FRONT WORKS THROUGH THE AREA IN THE MORNING, WHICH MAY
ALSO SPARK UP SOME DRIZZLE AMID THE COLDER TEMPERATURES BEFORE
LOW-LAYER RH DROPS BY 9 TO 10 AM. COLD CONDITIONS THEN FOLLOW
FOR THE NEXT SEVERAL DAYS. THERE ARE SMALL PRECIP CHANCES AGAIN
THURSDAY NIGHT AND POSSIBLY AGAIN SUNDAY BUT THESE ARE
ASSOCIATED WITH VERY MODEST FORCING. THE THURSDAY EVENT IS
ASSOCIATED WITH A POLAR AIRMASS SWEEPING A COLD FRONT IN AHEAD
OF A 1032 MB SURFACE RIDGE FROM THE GREAT LAKES WHICH WILL
RESULT IN TEMPERATURES AROUND 20 DEGREES BELOW SEASONAL NORMS
FOR THURSDAY.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
ISSUED AT 539 PM CST MON DEC 1 2025
IFR OR LOWER SNOW WILL SET IN EARLY THIS EVENING OVER THE
NORTHERN SITES AND END IN THE OVERNIGHT HOURS. SOME SLEET COULD
MIX IN EARLY ON AT KEVV AND KOWB. CEILINGS WILL EVENTUALLY DROP
TO IFR LEVELS AND THEN SLOWLY LIFT TO MVFR THROUGH THE DAY.
CLEARING IS POSSIBLE AT KMVN IN THE LAST HOUR OR TWO OF THE
FORECAST.
KCGI AND KPAH WILL SEE A MIXTURE OF FREEZING RAIN, SLEET, AND
SNOW WITH MVFR VISIBILITIES SET IN THIS EVENING. SOME IFR SNOW
IS EXPECTED BEFORE THE PRECIPITATION ENDS IN THE LATE EVENING
AND EARLY INTO THE OVERNIGHT. CEILINGS ARE EXPECTED TO STAY AT
MVFR LEVELS THROUGH THE DAY. CLEARING MAY REACH KCGI BEFORE THE
END OF THE PERIOD.
