Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 657 AM EDT Sat Aug 8 2020

SYNOPSIS. A return to more typical isolated to scattered summertime thunderstorm activity is expected over the weekend as modest drying arrives from the west. Deeper moisture will gradually return early next week and support a more active pattern from Tuesday onward.

NEAR TERM /THROUGH TONIGHT/. As of 650 am: Expect widespread low stratus and patchy dense fog to persist in the mountain valleys and across portions of the foothills until late morning, while stratus will continue to impact the Piedmont for the next couple of hours.

Otherwise, a short wave trough will continue to progress across the northeast quadrant of the country through the morning, and drier low level air will try to filter into the Eastern Seaboard in its wake. As such, guidance is a bit stingier with instability across the forecast area this afternoon in comparison with recent days, but nevertheless still adequate to support deep convection. Meanwhile, short term guidance is in good agreement in migrating a weak short wave trough across the forecast area throughout the day. All told, conditions should be favorable for diurnal convective initiation, although coverage should be a bit less than what one would usually expect for mid-summer, generally 20 to 40% across the mtns, and 20% or less east. With less in the way of low clouds expected across the area this afternoon, max temps are forecast to be right around normal. Convection should diminish quickly this evening, giving way to a seasonably warm and muggy night.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. As of 305 AM EDT Saturday: the short-term fcst picks up at 12z on Sunday with weak, WLY flow aloft and broad upper ridging in place across the region. Little change is expected wrt the upper-level pattern thru the period, as broad upper ridging persists across most of the CONUS and weak, embedded upper shortwave energy gradually ripples eastward over the region. At the sfc, the deeper moisture and higher PWAT values are expected to remain displaced off to our east over the weekend as the weak upper trof axis translates east and fills in. On Monday, some degree of moistening is likely as return flow from the gulf gradually increases thru the day and profiles become more conducive for convection. Overall, no significant changes were made to the sensible fcst. Like Saturday, Sunday will see below climo PoPs with values increasing to near climo for Monday aftn/evening. Temps should be a few degrees above climo on Sunday and Monday, but with dewpts expected to mix out (at least to some degree) each day, Heat Indices should remain below 100 degrees for all but our southern-most zones.

LONG TERM /TUESDAY THROUGH FRIDAY/. As of 245 AM EDT Saturday: the extended fcst picks up at 12z on Tuesday with weak flow aloft and extensive upper ridging spread across most of the CONUS. The upper-lvl pattern is not expected to change much thru the period, with the polar jet remaining well to the north and over Canada while upper ridging persists across most of the CONUS. The sfc pattern will remain fairly messy thru the period as well, with the Bermuda High keeping generally moist, SLY flow over the southeast. On Tuesday, a weak cold front approaches the fcst area from the NW, but appears to stall out as it lays north of the CWFA early Wednesday. As it does, a weak lee trof appears to develop on Wednesday as moisture begins to pool over the region. This pattern will likely continue for the rest of the period as improving SLY flow brings a resurgence of gulf moisture over the region for Thursday and beyond. Overall, there were no significant changes made to the fcst with diurnally-driven, above-climo PoPs each day and temps a few degrees above normal for Tuesday and Wednesday and near normal for for Thursday and Friday.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. At KCLT and Elsewhere: IFR or low MVFR cigs have developed at KCLT and the upstate SC terminals, while LIFR or VLIFR conditions persist at KAVL and KHKY. These conditions are expected to persist until late morning, with all indications pointing toward a quicker improvement in conditions than we've seen the past couple of mornings. Otherwise, while convection is forecast to develop across the area again this afternoon/evening, coverage is expected to be somewhat limited . generally widely scattered across the mountains, and isolated across the Piedmont and foothills. As such, Prob30s for TSRA during the late afternoon/evening only appear warranted at KAVL at this time. Overnight/early morning Sunday restrictions should be confined to mountain valley fog/low stratus, with 4SM/SCT004 forecast at KAVL, although conditions could prove to be quite similar to this morning at that site.

Outlook: Coverage of diurnal convection is expected to remain somewhat sparse through Monday, but will begin to increase again by mid-week. Morning fog/stratus restrictions will also be possible each morning, especially over the usual mountain valleys.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
