.DISCUSSION...
A MODIFIED ARCTIC AIRMASS REMAINS ACROSS THE TN VALLEY WITH SNOW
COVER STILL PRESENT ACROSS PORTIONS OF THE AREA. ENE SFC FLOW WILL
GRADUALLY VEER TO THE SE TODAY AS THE SFC ARCTIC HIGH PRESSURE SYSTEM
MOVES OFF TO THE EAST. AS IT NEARS THE MARYLAND/DELAWARE COASTLINE,
COLD AIR DAMMING WILL DEVELOP ON THE LEE OF THE APPALACHIANS. THIS
WILL GRADUALLY SEND COOLER AIR SW TOWARDS THE CAROLINAS/GA AND N AL
LATER THIS EVENING/TONIGHT. HOWEVER, OVER THE NEXT SEVERAL HOURS,
TEMPERATURES SHOULD WARM QUICKLY INTO THE UPPER 40S TO LOW 50S AS A
COMBINATION OF CLOUD BREAKS AND SE FLOW SHOULD MODIFY THE ARCTIC
AIRMASS.

DID MAKE SOME TWEAKS TO THE SKY COVER TODAY WITH LOWER END MOSTLY
CLOUDY CONDITIONS GIVEN THE CLOUD BREAKS AND VIS SATELLITE SHOWING
ADDITIONAL CLEARING IN THE LOW CLOUDS, BUT STILL THIN MID-HIGH LEVEL
CLOUDS. UAH-MIPS CEILOMETER ALSO INDICATES CLOUD COVER BREAKS WITH
THE CLOUDS MOSTLY BETWEEN 8-11 KFT.

OTHERWISE, MADE TREND ADJUSTMENTS TO BOTH AIR AND DEWPOINT
TEMPERATURES WITH FORECAST DAYTIME HIGHS LOOKING OK FOR NOW.
