...SYNOPSIS...

A WARM FRONT MOVING NORTHEAST THROUGH THE MIDDLE OHIO VALLEY AND
CENTRAL APPALACHIANS WILL KEEP THUNDERSTORMS SCATTERED ABOUT EASTERN
AND NORTHERN WEST VIRGINIA...AND BACK INTO SOUTHEAST OHIO...THIS
MORNING.  A WEAK UPPER DISTURBANCE WILL INTERACT WITH THE WARM FRONT
AND AFTERNOON HEAT...TO MAKE THUNDERSTORMS MORE LIKELY IN THE
MOUNTAINS THIS AFTERNOON.

A STRONGER UPPER LEVEL DISTURBANCE...ORIGINATING FROM THE
CENTRAL PLAINS...WILL APPROACH LATER TODAY AND TONIGHT...
MAKING THUNDERSTORMS MORE LIKELY.  ANY THUNDERSTORM THROUGH TONIGHT
CAN PRODUCE HEAVY TO EXCESSIVE RAINFALL AND FREQUENT LIGHTNING.

THE WEATHER WILL REMAIN UNSETTLED THROUGH THE END OF THE WEEK AS
THE UPPER LEVEL LOW PRESSURE SYSTEM WORKS ITS WAY EASTWARD INTO
THE REGION. SHOWER AND THUNDERSTORM CHANCES CONTINUE IN THIS
ACTIVE WEATHER PATTERN...INCLUDING AREAS THAT HAVE BEEN SATURATED
WITH RECENT DOWNPOURS.

THE WEATHER TURNS NOTICEABLY COOLER DURING THE FIRST HALF OF NEXT
WEEK. THE STUBBORN UPPER LEVEL LOW PRESSURE WILL PERSIST...WITH
CLOUDS AND SHOWERS STAYING IN THE FORECAST.
