.DISCUSSION...
AS A POLAR AIRMASS CONTINUES TO ADVECT SOUTHEAST, BOTH AIR AND
DEWPOINT TEMPERATURES HAVE BEEN DROPPING RAPIDLY. DAYTIME HIGH
TEMPERATURES NEAR 60 DEGREES HAVE SINCE DROPPED INTO THE 30S OVER TN
AND LOW 40S OVER MUCH OF AL. OVERNIGHT LOWS ARE STILL FORECAST TO
DROP INTO THE UPPER TEENS OVER TN AND LOWER 20S ACROSS THE REST OF
THE TN VALLEY. NORTHWEST WINDS CONTINUE TO BE BREEZY/GUSTY
TRANSLATING TO WIND CHILLS IN THE TEENS AND SINGLE DIGITS (TN) BY
MORNING.

THE CORE OF THIS COLD AIR IS WELL TO THE NORTHWEST WITH THE 1044 MB
HIGH PRESSURE SYSTEM CENTER OVER EASTERN ND. IT SHOULD SLOWLY MOVE
SOUTHEAST TOWARDS THE OH AND TN RIVER VALLEYS OVER THE NEXT 24 HOURS.
MEANWHILE, LOW CLOUD COVER, ASSOCIATED WITH A SHORTWAVE TROUGH
ROUNDING THE EASTERN FLANK OF THE PARENT LONGWAVE TROUGH OVER THE
EASTERN HALF OF THE COUNTRY, IS CURRENTLY CROSSING WESTERN AND
PORTIONS OF CENTRAL TN. THESE CLOUDS MAY BRIEFLY BRUSH FRANKLIN
(TN), MOORE, AND JACKSON COUNTIES, BUT WILL LIKELY ONLY CAUSE PARTLY
CLOUDY SKY CONDITIONS OVER THOSE AREAS WITH GENERALLY CLEAR
ELSEWHERE.
