Area Forecast Discussion National Weather Service Charleston SC 750 PM EDT Mon Aug 10 2020

SYNOPSIS. The region will remain positioned between Atlantic high pressure well to the east and an inland area of broad low pressure.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Early this evening: The radar is a bit chaotic this evening thanks to numerous outflow boundaries seemingly propagating in many different directions. The two main outflow boundaries include one marching to the southeast associated with convection that moved in from the Midlands and central Georgia, and the other is one moving at about 25 knots to the northeast. The main line of convection currently runs from around Sylvania to around Orangeburg and is trying to progress to the southeast. The interesting thing is that the boundary moving to the northeast seems to be cutting off and destabilizing much of the area out ahead of the convection. All of that to say, it is unclear how far to the southeast this convection will be able to progress especially in the presence of sunset and decreasing surface heating. We aren't very confident that convection will be able to make it all the way into Beaufort or the Charleston area as it may dissipate and wane before moving that far. Overall, the severe threat isn't particularly high. There is some wind showing up on base velocity data, but with updrafts that are struggling to produce much significant reflectivity near the -20 C height (27.2 kft) it is hard to see severe level gusts occurring.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. The synoptic pattern continues to change little through the period. A broad, deep layer trough of low pressure will remain to the west with a deep layer Atlantic ridge to the east- southeast. South- southwest low-level flow is expected to become onshore near the coast each afternoon due to the sea breeze. Given the orientation of the coastline, the southerly sea breeze will push further inland for our SC area, whereas in GA, the sea breeze will remain parallel to the coast. A weak land breeze may set up in the overnight/early morning hours, producing showers over the marine zones with mainly chance PoPs in place during those periods. Models hint at a weak mid- level shortwave that passes over the area Tuesday night, therefore likely PoPs are in place for much of the GA area with chance PoPs over the remaining SC land areas. As has been the case for the past week, the sea breeze and convective outflow boundaries will be the main focus for any showers and thunderstorms. Generally chance to low-end likely PoPs are forecast for the afternoon and early evening showers/thunderstorms each day. High temperatures remain in the normal range, mostly in the lower 90s. Lows above normal in the lower to mid 70s, except upper 70s along the immediate coast. Upper level flow remains weak and will continue to result in slow-moving storms. With plenty of deep layer moisture and P-WATS hovering just above 2 inches, some storms could produce locally heavy rainfall.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. Global models begin to diverge during this period, but the consensus solution indicates the potential for a slightly sharper upper trough trying to push toward the area from the northwest. If this happens, the upper flow would back to more southwest, helping to draw even more tropical moisture northward, while also potentially providing some upper level diffluence. Thus, blended guidance continues to show likely PoPs, which seems a bit high for so far out in time, especially when climo PoPs are 30-40%. However, as has been the case, these PoPs collaborate well with surrounding offices. Did cap PoPs to high end chance for the end of the period/Monday due to some indication of a lowering of deep layer moisture. This pattern may also become more conducive for locally heavy rainfall with deep layer/uni-directional flow from the southwest, resulting in a higher potential for training of convective cells. Have kept temperatures close to normal given uncertainty with PoPs and potential afternoon cloud cover.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. This evening, thunderstorms are currently upstream of both KCHS and KSAV. It appears that the better chance of seeing direct impacts is at KCHS, but it remains unclear if thunderstorms will persist long enough to make it. Given the uncertainty, kept the mention of thunder out of both sites. Overnight, no significant fog or stratus concerns. We could again see thunderstorms Tuesday afternoon and evening, but not enough confidence to introduce anything at this point.

Extended Aviation Outlook: Models continue to indicate the potential for scattered to numerous showers and thunderstorms, mainly in the afternoon and evening. Brief flight restrictions at both sites are possible each afternoon/evening.

MARINE. Tonight: Tranquil conditions will prevail outside of any convection. S winds around 10 kt this evening are expected to veer to the SW after midnight. Seas will average 1-2 ft.

No highlights are expected through the week. The waters will remain between Atlantic high pressure to the east and a broad area of lower pressure well inland. Southerly winds of 15 knots or less and seas of 3 feet or less are expected. A weak afternoon sea breeze will turn winds southerly/onshore near the coast each afternoon. Scattered showers and thunderstorms are expected mainly late night and early morning.
