SYNOPSIS
A weak cold front will linger over the area this weekend before the front slowly lifts back northward early next week. High pressure will then ridge in from offshore mid to late next week.

NEAR TERM /THROUGH TONIGHT/
Today: The upper levels of the atmosphere will be dominated by ridging over the southeastern states, building in from the SW. At the surface a weak cold front is forecast to be just inland of the local forecast area. This cold front will slowly sink southward through the daytime hours, however it is not expected to bring many impacts to the local area. The main forecast story for today is the heat. 850 hPa temperatures are forecast to be around 18/19C, which given decent daytime mixing today yields surface temperatures in the upper 90Fs, close to 100F. The current forecast features highs representative of this, away from the beaches where conditions will remain slightly cooler in the upper 80s. Dew points are forecast to mix out, which will limit heat index values to 100-101F, below Heat Advisory criteria. The temperature at the KCHS may challenge the record high temperature, see the Climate section for more details. As the cold front sinks southward CAMs depict isolated convection, mainly across southeast SC in the later afternoon hours. It is worth noting that model soundings indicate a significant amount of dry air in the upper levels, a result of subsidence aloft.
Showers and thunderstorms may struggle to overcome the dry air.
Any showers/thunderstorms that are able to form will likely dissipate with nightfall.

Tonight: The cold front will likely be stalled across southeast GA around nightfall, with high pressure building in from the north behind it. A quiet night is forecast, with any showers/ thunderstorms likely dissipating by nightfall. Overnight lows will generally be in the low 70s away from the coastline, where temperatures should remain in the mid 70s.

SHORT TERM /SUNDAY THROUGH TUESDAY/
Sunday: Strong upper ridging persists aloft. At the surface, strong high pressure over New England will build down the eastern seaboard, forcing a weak cold front southward across the area. Rainfall coverage Sunday will ultimately be dependent on the progression of the front, which will most likely be bisecting the area by midday, and potentially be pushing down into Georgia by the evening. While very dry air aloft will inhibit convective growth, there should be enough moisture pooling on the southern side of the front (PWATs 1.5+ in) and instability (1500+ J/kg) to get a few isolated to widely scattered showers and storms following a mainly diurnal pattern, with any storm activity diminishing in the evening and dry conditions prevailing overnight.

Despite the very strong upper ridging, E to NE/onshore flow will moderate low level thickness values, and temps Sunday will be only a few degrees above normal, upper 80s to lower 90s near the coast, and mid 90s inland.

Monday and Tuesday: Upper pattern remains similar Monday and Tuesday with ridging directly overhead leading to strong subsidence/very dry air aloft. The aforementioned front will deteriorate near/over the area Monday as it begins to lift back north, with surface ridging building in from offshore by Tuesday. Rainfall chances confined roughly along and south of I-16 both days, where there could be just enough moisture to develop some short-live showers/storms around peak heating/maximum instability each afternoon. Onshore component of BL flow keeps temps near to a few degrees above normal both days despite the strong upper ridging.

LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/
Upper ridging shifts north mid-to-late week, with height falls aloft leading to diminishing upper subsidence. At the surface, high pressure migrates off the Northeast coast and toward a more seasonable Bermuda High location. Expect the forecast to trend back toward a more summer-like precip pattern, with scattered afternoon thunderstorms along and inland of the sea breeze and lesser storm activity overnight. Temps remain within a few degrees of normal.

AVIATION /07Z SATURDAY THROUGH WEDNESDAY/
KCHS/KJZI/KSAV: VFR through the 06 Z TAF period. There could be a little shallow ground fog that develops at any of the terminals early this morning, but no major impacts are expected. Isolated showers/tstms associated with an approaching cold front could make a run for KCHS and KJZI mid-late afternoon, but confidence on impacts is too low to include a mention of VCTS or TSRA for now.

Extended Aviation Outlook: Mainly VFR. There will be low probabilities of brief flight restrictions due to convection each afternoon/evening.

MARINE
Today and Tonight: Generally tranquil marine conditions are forecast through tonight. A weak cold front is forecast to progress southward through the forecast area through the daylight hours, stalling across southeast GA this evening. Winds will generally be S around 10 knots, with seas averaging 2 to 3 ft. With the cold front to the south of the area, overnight winds are forecast to shift to the E, still remaining around 10 knots.

Sunday through Wednesday: The gradient will remain fairly weak through Monday as a front moves over the area and slowly deteriorates. High pressure builds in from the north early next week, then shifts offshore mid-to-late week, with mainly moderate winds prevailing, but breezy/gusty conditions near the coast with the sea breeze formation each afternoon. Modest medium period southeast swell will keep 2-4 ft seas in place through Monday, with seas increasing to 3-5 ft Tuesday through mid-week as increasing fetch over the Sargasso sea causes the the southeast swell builds further. 6 ft seas/SCA conditions could emerge by late week.
