Key MESSAGE 1, High pressure will continue to build across the Mid-Atlantic and Carolinas tonight into Tuesday with a cooler/drier NE-E flow over the area bringing seasonable and comfortable temps for early September, with highs in the low to mid 80s and dewpoints generally in the 60s. Temps will begin to warm mid to late week as the high shifts offshore allowing southerly flow to re-develop ahead of the next front and high temps climbing back into the upper 80s to lower 90s and dewpoint temps into the low to mid 70s late in the week. Mostly dry weather will prevail through mid week as upper ridging build in from the west and a drier airmass in place, however a few shower will linger across the offshore coastal waters through tonight.
KEY MESSAGE 2, The upper ridge begins to break down for the latter half of the week as a shortwave and attendant cold front push across the Midwest and Mid-Atlantic states. Guidance continues to show the front pushing into ENC on Friday and stalling along the coast through the weekend bringing unsettled weather across the region.
18z Monday through Saturday VFR conditions will prevail through Tuesday as high pressure builds into the region bringing a drier airmass. Diurnal Cu this afternoon will dissipate with loss of heating this evening. Nw winds will continue to gust to around 15-20 kt this afternoon, becoming light tonight. Inland areas are expected to decouple bringing good radiational cooling conditions overnight, but with a dry airmass in place fog development is unlikely but still cannot completely rule out patchy shallow ground fog at some inland terminals, however it will likely have very limited impact to operations. Vfr conditions continue Tuesday with sct diurnal Cu and lighter winds throughout the day.
NOTE: AMD NOT SKED has been appended to the EWN TAFs as the site is not transmitting through normal channels. The site is still reporting via telephone so it will be monitored, but not as frequently as when it is completely operational. The next closest ASOS is at Cherry Point (KNKT).

Sw winds 5-15 kt return Wed night and 10-20 kt Thu with seas building 2-4 ft as a front approaches the area.
