.DISCUSSION...
KEY MESSAGE 1...

Additional rounds of showers and thunderstorms are expected to
move through the area today through Monday night, with most
robust activity occurring in concert with a couple of
shortwaves.

Activity will be isolated to scattered this afternoon, then the next
round of more widespread activity arrives this evening. A Flood
Watch has been issued for southeast Ohio and much of West Virginia,
where heavy downpours could rapidly produce a couple inches of rain
overnight and Monday morning. Locations that already received heavy
rain earlier today will be at greatest risk for flash flooding
overnight. Additional rain on Monday could necessitate an
extension to the Flood Watch. A few strong to severe storms
could also be capable of producing locally strong wind gusts.

From Tuesday through Thursday, the pattern remains unsettled with
additional chances for flooding as an upper trough spirals across
the Middle Ohio Valley towards the east coast. Drier conditions
return late week into the weekend as the system pushes off the
Atlantic Coast.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...

Conditions this evening will generally be VFR, although a few
showers and thunderstorms could briefly cause restrictions.
Showers and thunderstorms may become more numerous later
tonight, but confidence on the location is low. In addition, fog
or low stratus could form at locations where there are enough
breaks in the clouds.

Expect a rising cumulus deck on Monday with more showers and
thunderstorms, especially during the afternoon hours.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z TUESDAY...

FORECAST CONFIDENCE: High this evening, then low late tonight
and Monday morning. Medium Monday afternoon.

ALTERNATE SCENARIOS: Timing, location, and intensity of
