VERY WARM AGAIN THIS AFTERNOON AHEAD OF THE FRONT, AND HIGHS ARE
FLIRTING WITH DAILY RECORDS AGAIN AT CHA, OQT, AND TRI. TODAY'S
RECORD HIGHS ARE BELOW:
DATE CHATTANOOGA KNOXVILLE TRI-CITIES OAK RIDGE
10-16 85(1953) 87(1897) 83(1984) 83(2016)
A STRONG COLD FRONT WILL BE PUSHING THROUGH OUR AREA THIS AFTERNOON,
WITH GUSTY WINDS AND SOME SHOWERS. A FEW RUMBLE OF THUNDER CANNOT
BE RULED OUT FAR NORTH, BUT CAPE LOOKS VERY LIMITED. WE WILL SEE
SOME WIND GUSTS APPROACHING OR IN A FEW SPOTS POSSIBLY EXCEEDING 30
MPH THIS AFTERNOON, AND THESE GUSTY WINDS WILL LINGER THROUGH
TONIGHT OVER SOME OF THE HIGHER ELEVATIONS. THE SHOWERS WILL
CONTINUE BEHIND THE FRONT TONIGHT AS A DEEP MID/UPPER LEVEL TROUGH
DIGS THROUGH THE REGION, THEN TAPER OFF LATE TONIGHT WITH JUST A FEW
SHOWERS LINGERING INTO SATURDAY MAINLY OVER THE HIGHER ELEVATIONS.
AS MUCH COLDER AIR PUSHES IN BEHIND THE FRONT, SOME SNOW WILL LIKELY
MIX IN OVER THE HIGHER MOUNTAIN PEAKS LATER TONIGHT INTO EARLY
SATURDAY BEFORE THE PRECIPITATION ENDS. SNOW MAY EVEN WHITEN THE
GROUND WITH VERY LIGHT SNOW ACCUMULATION OVER THE HIGHEST PEAKS LATE
TONIGHT/EARLY SATURDAY BEFORE IT MELTS.
THE WEEKEND WILL BE COOL WITH HIGH TEMPERATURES WELL BELOW SEASONAL
NORMALS SATURDAY AND STILL SEVERAL DEGREES BELOW NORMAL SUNDAY. WE
WILL LIKELY SEE THE FIRST FROST OF THE SEASON FOR PORTIONS OF THE
AREA SATURDAY NIGHT. RIGHT NOW THE QUESTION FOR FROST SATURDAY
NIGHT IS HOW MUCH WIND WILL BE STIRRING, WHICH COULD KEEP THE FROST
CONFINED MORE TO SHELTERED VALLEYS. IT WILL BE MOSTLY CLEAR AGAIN
AND WINDS WILL LIKELY BE LIGHTER SUNDAY NIGHT, WITH FROST AGAIN
POSSIBLE ESPECIALLY NORTH AND IN OUTLYING AREAS FURTHER SOUTH. NO
FROST ADVISORIES, SINCE WE ARE PAST THE DATE FOR ENDING
THE ISSUANCE OF FROST/FREEZE PRODUCTS FOR THE FALL.
HIGH PRESSURE IS FORECAST TO BE IN CONTROL AS WE HEAD INTO NEXT
WEEK. MONDAY THROUGH FRIDAY LOOK DRY WITH A GRADUAL WARMING TREND.
