MORE LOW CLOUDS ARE ON THE WAY AS OUR REINFORCING COLD SHOT
MAKES ITS MOSTLY DRY PASSAGE. WHILE SOME LIGHT ECHOES THAT SHOW
UP ON LONG PULSE RADAR MODE MIGHT PRODUCE A LIGHT SNOW FLAKE OR
FLURRY ALONG/NORTH OF I-64 AS THE NOSE OF THE AIR MASS ARRIVES
THIS MORNING, AMOUNTS AND CHANCES ARE NEGLIGIBLE. ANOTHER SMALL
CHANCE OF LIGHT PCPN OCCURS THIS EVENING, WHEN A SURGE OF
OVERRUNNING MOISTURE THAT IS LARGELY TO OUR SOUTH CLIPS OUR FAR
SOUTHEAST COUNTIES/CWA BORDER AREA. WHILE A FLURRY CANNOT BE
RULED OUT AND THE BUILDER PRODUCES A HINT OF -FZRA, AMOUNTS
RANGE FROM T-0.01" AND CHANCES OF THIS OCCURRING ARE LESS THAN
30 PERCENT.
ANOTHER UPPER TROF MAKES PASSAGE THIS WEEKEND, BRINGING THE NEXT
BEST CHANCE OF PCPN OVER ITS BACK HALF. WE'RE MOSTLY ABOVE
FREEZING DURING THIS WINDOW OF TIME, SO IT'S ALL LIQUID SAVE
FOR A BRIEF PERIOD ACROSS THE NORTH SATURDAY NIGHT. AMOUNTS ARE
NEGLIGIBLY LIGHT AND POPS REMAIN SCANT, WITH THE SYSTEM'S MAIN
IMPACT BEING ANOTHER PUNCH OF COLD AIR THAT KEEPS TEMPERATURES
WELL BELOW NORMAL RIGHT ON THRU THE REMAINDER OF THE WEEKEND AND
THE BEGINNING OF THE NEW WORK WEEK.
FINALLY SOME MODERATION OCCURS BY THE MIDDLE OF NEXT WEEK AS
HIGH PRESSURE SHIFTS EAST IN THE WAKE OF THAT DEPARTED SYSTEM,
AND RETURN FLOW SOUTHERLIES DEVELOP. 40S AND 20S ARE FOLLOWED
BY 50S AND 30S OR CLOSER TO SEASONAL NORMS.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1114 AM CST THU DEC 4 2025
PERSISTENT LOW (IFR TO LOW MVFR) CLOUDS SEEM MORE LIKELY THAN
NOT TO HANG ON FOR MOST OF THE REST OF THE DAY SOUTH OF I-64.
POORER VISIBILITIES AND LOWER CEILINGS ARE EXPECTED THE CLOSER
YOU GET TO THE KY/TN AND MO/AR BORDER THROUGH THE NEXT FEW
HOURS AS WEAK PRECIP MOVES ACROSS WESTERN TN. THERE IS SOME
PRESSURE FROM THE WEST TO CLEAR OUT AND PLACES LIKE CGI HAVE THE
BEST CHANCE TODAY BUT THE HIGHEST PROBABILITY - THROUGH 06Z OR
SO IS FOR THE CLOUDS TO STICK AROUND.
SOME IMPROVEMENT IS POSSIBLE EARLY FRIDAY MORNING BUT CLEARING
MAY ONLY SERVE TO LEAD TO GROUND FOG. BETTER OVERALL CONDITIONS
SEEM PLAUSIBLE FOR FRIDAY AS THE PARENT UPPER STORM SYSTEM
SLIDES SLIGHTLY FURTHER EAST.
