.AVIATION...
CURRENT SURFACE ANALYSIS SHOWS A WEAK COLD FRONT GENERALLY ALONG THE
CUMBERLAND PLATEAU...WITH RADARS REVEALING SOME SCATTERED CONVECTION
DEVELOPING OVER EASTERN KY. A MARGINALLY UNSTABLE AIR MASS IS
PROGGED TO DEVELOP OVER THE TAF SITES THIS AFTERNOON...AS A BROAD
UPPER-LEVEL TROUGH AMPLIFIES OVER THE EASTERN HALF OF THE NATION. AS
A RESULT...EXPECT SCATTERED CONVECTION TO DEVELOP AROUND KTRI AND
KTYS BY MID TO LATE AFTERNOON...BUT WILL ONLY MENTION VCTS FOR
NOW...SINCE TIMING THE EXACT OCCURRENCE AT THE TAF SITES WILL BE
PROBLEMATIC. OTHERWISE...WESTERLY WINDS WILL CONTINUE OVERNIGHT...
WHICH SHOULD PREVENT ANY FOG FORMATION AT THE TAF SITES. CEILINGS
AND VISIBILITIES WILL GRADUALLY RISE THROUGHOUT THE TAF PERIOD AT
ALL THREE TAF SITES...AS DRIER AIR WORKS ITS WAY INTO THE REGION.
