-- Changed Discussion --
As of 150 AM Tuesday... An upper level trough will amplify as it shifts eastward into the mid-Atlantic and Carolinas. A couple of shortwaves will move through the area as they traverse the base of the upper trough, one early Wed, the other Wed night/early Thu. At the surface, the cold front should finally be east of central NC and offshore by Wed morning, however a lee trough may briefly develop in the wake of the front over the area during the day Wed. A dry, reinforcing cold front should move through Wed night, pushing the trough offshore as cool high pressure ridges in from the WNW. Highs Wed should be a category or two below normal, ranging from mid 70s north to low/mid 80s south. Lows Wed night in the low 50s north to around 60 degrees south expected.

-- Changed Discussion --
As of 210 AM Tuesday... The upper level trough will amplify as a strong s/w swings through the northern mid-Atlantic/Northeast US, with the parent trough progressing eastward through the mid-Atlantic and Carolinas Thu/Thu night. The trough should shift east and offshore on Fri, with the sub-tropical ridge progressing eastward toward the region through Fri night. The ridge will slowly progress eastward through the area Sat/Sat night. Meanwhile to the west, a s/w trough will move eastward through the MS Valley Fri night/Sat, then continue eastward through the OH Valley and mid-Atlantic Sat night/Sun. Another s/w will follow behind it, however the model guidance varies wrt timing and track. At the surface, cool high pressure will gradually progress esewd through the Great Lakes and OH Valley Thu/Fri, then slide sewd through the mid-Atlantic/Carolinas and offshore Sat/Sat night. As the high continues to drift eastward over the Atlantic, southerly return flow will once again advect warm, moist air into the area through early next week. For now, expect largely dry weather through Sat night, with chances for precipitation returning for Sun and Mon. Temperatures should be near to below normal through the remainder of the forecast period.

&& .AVIATION /06Z TUESDAY THROUGH SATURDAY/... As of 155 AM Tuesday... RWI will likely bounce around between 2-3SM while thin cirrus spreads in from the southwest. Timing the upper level clouds to move out to TEMPO LIFR fog given recent observations and saturated ground from moderate rainfall yesterday afternoon. Latest guidance shows a tongue of patchy fog and low stratus developing over upstate SC into the southern Piedmont of NC towards daybreak, but should remain south of the Triad terminals (GSO/INT) as dew points have already dropped into the low/mid 60s. A cold front will move through the area through the early morning hours with a NW wind shift at all terminals by 13z. Surface winds will increase to around 10 kts with gusts up to 15-20 kts possible during the afternoon. Showers and isolated storms may form along the seabreeze this afternoon, but should remain southeast of FAY. Outlook: Mostly VFR conditions should persist through Saturday as dry high pressure wedges in. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...CA NEAR TERM...CA SHORT TERM...KC LONG TERM...KC AVIATION...Swiggett/Green
