THE OH VALLEY, WIDELY SCATTERED THUNDERSTORMS HAVE FORMED IN A
MODERATELY UNSTABLE AND UNCAPPED WARM SECTOR FROM EASTERN OH INTO
WESTERN/CENTRAL PA. LOCAL VWPS SHOW RELATIVELY STRAIGHT HODOGRAPHS

REMAIN SUFFICIENT FOR SEVERE STORMS FOR THE NEXT FEW HOURS WHERE
BOUNDARY-LAYER DEWPOINTS ARE IN THE 60S. ANY TORNADO THREAT WILL
LIKELY BE TIED TO LOCAL TERRAIN INFLUENCES AND/OR FAVORABLE STORM
INTERACTIONS. THEREAFTER, COOLING SURFACE TEMPERATURES AND GRADUAL
STABILIZATION SHOULD BEGIN TO LESSEN THE THREAT. A SEVERE
THUNDERSTORM WATCH IS BEING COORDINATED NOW WITH LOCAL NWS OFFICES
TO REFLECT THE SEVERE-STORM THREAT INTO THIS EVENING.
