.NEAR TERM /THROUGH TONIGHT/... As of 140 AM EDT Monday...
Key Messages:
1. Light rain showers arrive this afternoon and evening.
2. Cooler and cloudy with northeast flow.
Tropical Storm Imelda will continue to slowly move north out of the Bahamas and then begin to move east out into the Atlantic. Some moisture will be drawn northward from the tropics today, mainly in the form of just some scattered showers this afternoon and evening. Rain coverage/intensity will gradually diminish tonight with mainly areas of drizzle and low clouds overnight tonight. At the moment, rainfall amounts now look to only be around 0.25" or less with the upper range being across Southside Virginia and north central North Carolina.
Temperatures will feel a bit cooler today with a northeast breeze and cloud cover keeping warming to minimum.

.SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... As of 1250 AM EDT Monday...
Key Messages:
1) Rain showers could linger through Tuesday but should diminish by Tuesday night to provide dry weather afterward.
2) Temperatures will trend lower on Thursday due to a cool northeast flow as high pressure wedges against the Blue Ridge.
Moisture being advected northward from Tropical Storm Imelda may linger into Tuesday, but it will dwindle due to a drier northeast flow as high pressure from Canada builds southward. As Imelda turns eastward late Tuesday, the Canadian high should firmly wedge itself against the eastern slopes of the Blue Ridge. Conditions will turn drier for the remainder of this forecast period. Temperatures should also dip lower for Wednesday night into Thursday with lows mainly in the 40s and highs generally in the 60s.

.LONG TERM /FRIDAY THROUGH SUNDAY/... As of 1250 AM EDT Monday...
Key Messages:
1) Dry weather will persist through Friday and the upcoming weekend.
2) Temperatures should moderate a little towards the weekend.
High pressure should remain wedged against the eastern slopes of the Blue Ridge through Friday. As the high slowly weakens and drifts offshore by the upcoming weekend, the cooler northeast flow should abate and allow some moderation in the temperatures. Dry weather will continue throughout the weekend with more locations having highs in the 70s. Several model solutions suggest that this stretch of dry weather might last notably longer into the following week.

.AVIATION /06Z MONDAY THROUGH FRIDAY/... As of 200 AM EDT Monday...
Mostly VFR across the region. However, high level clouds associated with Tropical Storm Imelda have already begun pushing into the area, and will expect this trend to continue through the morning. MVFR ceilings or lower will reach KDAN first by mid to late morning, and then spread to KLYH, KROA, and KBCB by Monday afternoon, coinciding with the onset of light rain for those terminals. Rain may reach as far west as KBLF, but confidence is lower.
Patchy fog is possible again this morning, but may not be as dense/widespread, given the encroaching cloud cover. Confidence is also lower on specific vsby values, but better confidence that KBLF and KLWB will see lower vsbys than the other area terminals due to lack of cloud cover.
Winds will remain generally from the northeast, between 5 to 10 knots, and may gust up to 15 knots by the afternoon.
EXTENDED AVIATION OUTLOOK...
Rain showers may continue on Tuesday as easterly flow brings moisture back into the area from the Atlantic Coast, with the potential for gusty winds Tuesday into Wednesday. Expecting VFR conditions to return after rain ends Tuesday night, for Wednesday through Saturday, except for patchy morning fog.
