Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 305 PM EDT Fri Aug 12 2022 .SYNOPSIS... Canadian high pressure will bring cooler and drier air to the region through the weekend. Gradually increasing moisture is expected next week. Other than a brief warm-up early next week, temperatures are and expected to remain cooler than normal for much of the week. && .NEAR TERM /THROUGH SATURDAY/... As of 140 PM EDT Friday: Despite drier air moving into the area behind the departing cold front, low level moisture lingers. This has lead to weak instability across NC and moderate instability over the Upstate and NE GA. A weak short wave dropping into the upper trough over the area will help isolated convection to develop given the moisture and instability trends. Coverage should favor the Blue Ridge areas of NC, SC, and GA along with the Lakelands, but isolated convection can't be ruled out anywhere until loss of heating. Strong to severe storms seem unlikely, but given the high DCAPE values over the area, can't rule one out. Low level moisture lingers along and near the Blue Ridge. Developing easterly upslope flow could lead to low clouds overnight. Fog is unlikely except maybe in the normally more foggy locations. Lows should end up about 5 degrees below normal. Even the low level moisture moves out on Saturday and cooler and drier high pressure finally builds more fully into the area. That said, there may be enough moisture and weak instability for isolated showers over the Smokies. Highs will be about 5 degrees below normal with dew points dropping into the 50s across much of the area leading to a refreshingly low humidity day. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... As of 235 PM EDT Friday: the short-term fcst picks up at 00z on Sunday with extensive upper ridging still dominating the western 2/3 of the CONUS while fairly deep/broad upper trofing remains over the mid-Atlantic states. Over the next couple of days, the trof axis is expected to lift northeast of New England, yet upper trofing will remain largely in place across the region thru the end of the period late Monday. At the sfc, the center of broad high pressure will be translating eastward and over the Atlantic Coast as the period begins. By late Sunday, another cold front will approach our fcst area from the NW and bring an increase in moisture with it. The frontal bndy is not expected to actually move thru our CWA until late Monday as the period is ending. As for the sensible fcst, both PoPs and QPF have been increased late Sunday thru the end of the period late Monday. However, QPF is still not expected to be excessive and should not cause any significant hydro issues. Temps should remain just below normal both Sunday and Monday. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... As of 225 PM EDT Friday: the extended fcst picks up at 00z on Tuesday with broad upper trofing still in place over the Eastern CONUS and extensive ridging to the west. Over the next 24 to 48 hrs, the upper trof is expected to morph into a large, closed upper low and then expand further westward. By the end of the period late next week, the trof is expected to cover roughly the eastern half of the CONUS. At the sfc, a weak cold front will be moving east of our CWA as the period begins. In the front's wake, weak high pressure tries to spread back into the area from the north, however the latest long-range guidance has it making less southward progress into our area. At the same time, the synoptic pattern is looking more chaotic/uncertain with the operational models trying to develop multiple sfc lows over the Southeast and then move them eastward and off the SE Coast. Overall, the pattern is trending more active with the above-mentioned high not exerting as much influence over our area with solid-chance PoPs each day thru day 7. Temps are also trending cooler thru most of the period, with highs expected to start out about a category below normal on Tues, and remain 1 to 2 categories below normal thru day 7. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... At KCLT and elsewhere: SCT to occasionally BKN low VFR cumulus will be over the area this afternoon and early evening. Isolated showers and possibly a TSRA will move south across the area. Have VCSH in for now and can amend of cells threaten the TAF sites. Chance of convection ends this evening with loss of heating and deeper dry air moving in. There could be some lingering low level moisture overnight. This and developing easterly upslope flow could create low clouds over portions of the mountains and foothills. For now, have gone with FEW low clouds, but this will need to be monitored as well. Outside of the dissipation of any low clouds forming overnight, VFR conditions expected Saturday. NE wind, potentially with low end gusts, continues into the evening before dropping in speed. Low end gusts possible with mixing by mid morning Saturday. KAVL will see N wind with low end gusts this afternoon. Light N wind overnight, then S wind on Saturday. Outlook: Moisture slowly returns Sunday into early next week. Expect diurnal convective chances to slowly increase as well. Fog and low stratus may develop each morning in the mtn valleys. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None. NC...None.
