...SUMMARY...
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF
COLD FRONT FROM THE OHIO VALLEY TO THE GULF COAST FRIDAY. A FEW
MARGINALLY SEVERE THUNDERSTORMS ASSOCIATED WITH STRONG WIND GUSTS
MAY DEVELOP DURING THE MORNING AND AFTERNOON ACROSS PARTS OF THE
TENNESSEE VALLEY...CENTRAL GULF COAST STATES AND SOUTHERN
APPALACHIAN MOUNTAINS.

...TN VALLEY/CNTRL GULF COAST STATES/SRN APPALACHIANS...
AN UPPER-LEVEL TROUGH WILL MOVE EWD FROM THE GREAT PLAINS INTO THE
OZARKS FRIDAY MORNING AS A STRONG COLD FRONT ADVANCES QUICKLY EWD
INTO THE OH AND TN VALLEYS. A LARGE AREA OF THUNDERSTORM ACTIVITY
SHOULD BE ONGOING AT 12Z AHEAD OF THE FRONT FROM SE INDIANA SWD
ACROSS CNTRL KY...MIDDLE TN INTO NCNTRL AL AND POSSIBLY SWWD INTO
ERN MS. THIS ACTIVITY WILL BE ASSOCIATED WITH A LINEAR MCS THAT IS
FORECAST TO GRADUALLY DECAY DURING THE MORNING. A FEW STRONG WIND
GUSTS WILL BE POSSIBLE WITH THE BETTER ORGANIZED LINE-SEGMENTS AS
SFC TEMPS HEAT UP AFTER DAYBREAK. ADDITIONAL THUNDERSTORM
DEVELOPMENT SHOULD TAKE PLACE FRIDAY AFTERNOON FROM THE SRN
APPALACHIAN MTNS SSWWD TO THE CNTRL GULF COAST AHEAD OF THE FRONT
ALONG AN AXIS OF MODERATE INSTABILITY. ALTHOUGH LOW-LEVEL FLOW IS
FORECAST TO WEAKEN DURING THE DAY ACROSS THE TN VALLEY...FORECAST
SOUNDINGS STILL SHOW 0-6 KM SHEAR VALUES IN THE 30 TO 40 KT RANGE.
THIS COMBINED WITH STEEPENING LOW-LEVEL LAPSE RATES AND
UNIDIRECTIONAL WIND PROFILES MAY BE ENOUGH FOR A FEW STRONG WIND
GUSTS ACROSS ERN TN...NW GA AND PARTS OF AL DURING THE MID TO LATE
AFTERNOON ON FRIDAY.
