/ISSUED 742 PM CDT TUE OCT 21 2014/
A PLEASANT EVENING IS UNDERWAY ACROSS THE TENNESSEE VALLEY, WITH
EVENING TEMPERATURES ALREADY FALLING INTO THE MIDDLE 50S IN A FEW
LOCATIONS AS OF THIS WRITING. A REINFORCING COLD FRONT IS IN THE
PROCESS OF PUSHING SOUTHWARD THROUGH THE CWFA, WITH SLIGHTLY
COOLER/DRIER AIR IN TOW. THIS FRONT EXTENDS FROM CENTRAL IA/MO
SOUTHEASTWARD THROUGH SRN MIDDLE TN/NRN AL/GA AND THEN NORTHEASTWARD
INTO THE CAROLINAS/VIRGINIAS. NO PRECIPITATION IS OCCURRING WITH THIS
FRONT, AND IN FACT, ONLY A BRIEF WIND GUST OR TWO CAN BE PICKED OUT
ON REGIONAL METARS JUST TO OUR NORTH.

WEAK CAA OVERNIGHT IN ADDITION TO CLEAR SKIES/CALM WINDS WILL ALLOW
MORNING LOWS TO FALL INTO THE LOWER 40S, WITH A FEW NOTORIOUSLY
COOLER SPOTS DIPPING INTO THE UPPER 30S. WILL RETAIN THE FOG MENTION
FOR MAINLY SHELTERED VALLEY LOCATIONS, AS WELL AS THOSE IN CLOSE
PROXIMITY TO RIVERS/LAKES. ASIDE FROM A FEW ADJUSTMENTS TO HOURLY
TEMP GRIDS TO MATCH UP WITH OBSERVATIONAL TRENDS, NO ADDITIONAL
CHANGES WERE WARRANTED FOR THIS UPDATE.
