...NO TSTM AREAS FORECAST...

...TN VALLEY AREA...

A STRONG VORT MAX AND ATTENDANT MID LEVEL JET WILL MOVE SSEWD AND
INTO THE TN VALLEY AREA BY WEDNESDAY AFTERNOON. A POCKET OF STEEP
MID LEVEL LAPSE RATES ON THE CYCLONIC SIDE OF THE JET WILL SPREAD
INTO THE TN VALLEY AROUND THE TIME OF PEAK HEATING. HOWEVER...A
LARGE CP AIRMASS HAS SPREAD OVER THIS REGION WITH OFFSHORE FLOW OVER
THE GULF RESULTING IN A COOL...DRY BOUNDARY LAYER. PRECIPITATION
WILL LIKELY DEVELOP SEWD INTO THE TN VALLEY WITHIN THE ZONE OF
ASCENT ASSOCIATED WITH THE SEWD MOVING UPPER JET. STEEP MID LEVEL
LAPSE RATES AND SURFACE HEATING MAY CONTRIBUTE TO ENOUGH INSTABILITY
TO SUPPORT SHALLOW CONVECTION. ISOLATED LIGHTNING STRIKES MAY
ACCOMPANY SOME OF THIS ACTIVITY DURING THE AFTERNOON BUT IS EXPECTED
TO REMAIN TOO SPARSE TO INCLUDE IN A GENERAL THUNDERSTORM OUTLOOK.
