CONCERNING...SEVERE THUNDERSTORM POTENTIAL

VALID 071835Z - 071930Z

WW WILL BE ISSUED SOON FOR MUCH OF CENTRAL/SRN OH SWD ACROSS ERN
KY/WRN WV AND FAR SWRN VA.

AIR MASS ACROSS THE DISCUSSION AREA WILL CONTINUE TO DESTABILIZE
/MLCAPE AROUND 1000 J/KG NOW INTO FAR SWRN OH/ERN KY/TN/ AS
LOW-LEVEL MOISTURE RETURNS ENEWD THROUGH THE MID-UPPER OH/TN
VALLEYS.  THIS COMBINED WITH STRONG SURFACE HEATING AND STEEPENING
MID LEVEL LAPSE RATES PER REGIONAL 18Z SOUNDINGS WILL RESULT IN
MODERATE INSTABILITY ACROSS THE REST OF THIS AREA.  SWLY MID-LEVEL
WINDS WILL CONTINUE TO STRENGTHEN THIS AFTERNOON AS 60-80 JET
TRANSLATES ENE ACROSS THE OH VALLEY.  DEEP LAYER SHEAR ALREADY OVER
50 KT WILL SUPPORT ORGANIZED STRONG TO SEVERE STORMS.  ALTHOUGH WIND
FIELDS ARE GENERALLY UNI-DIRECTIONAL WITH LITTLE LOW-LEVEL
DIRECTIONAL SHEAR...STRONG LOW-LEVEL SPEED SHEAR AS INDICATED BY THE
18Z PIT SOUNDING SUGGESTS THE POTENTIAL FOR TORNADOES.

A FEW SHOWERS/ISOLATED THUNDERSTORMS HAVE ALREADY DEVELOPED ACROSS
ERN KY INTO WV...WITH UPSTREAM ACTIVITY ACROSS IND AND CENTRAL KY
EXPECTED TO MOVE INTO OH/ERN KY BY 20Z.
