SYNOPSIS
A weak cold front will linger over the area tonight before dissipating early this week. High pressure will then ridge in from offshore mid to late week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
This Evening: A weak cold front will be located across our area.
Afternoon radar imagery indicates isolated to scattered convection over our SC counties, moving WSW with the sea breeze.
This matches up fairly well with the CAMs and the HRRR. Likewise, SPC Mesoscale Analysis indicates MLCAPEs up to 1,500-2,000 J/kg across our northernmost counties. DCAPEs will be around 1,000 J/kg. So while there remains a lot of mid-level dry air in place per the model soundings, any stronger storms that manage to develop could generate strong. The convection will gradually decrease into this evening.

Tonight: Mid-level ridging persists, maybe even strengthening a bit. The weak cold front across our area should gradually lift to the north. The synoptic models and CAMs keep our area dry.
Though, there should be increasing high clouds from the SW overnight. Winds should also be light or calm. Lows should be in the upper 60s and lower 70s at most places, except the mid 70s closer to the coast.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/
Aloft, a ridge will remain centered across the Southeast and Mid- Atlantic States Monday, before becoming more elongated across the Northeast to Southeast United States Tuesday and Wednesday. At the sfc, a stalled front across the local area will likely dissipate early week, before high pressure builds across the region from the Atlantic by Tuesday. Weak coastal troughing developing along the southern periphery of the ridge is anticipated just off the Southeast Coast, which should favor few to potentially scattered showers and thunderstorms across coastal areas, mainly south of Beaufort, SC and into southeast Georgia Monday and Tuesday afternoon/evenings, before precip coverage gradually increases and shifts slightly further inland Wednesday as ample moisture arrives within a prolonged onshore flow. High temps in the upper 80s nearshore to lower 90s inland Monday should trend a degree or two cooler each day through Wednesday with the onshore flow prevailing. Overnight lows will range in the mid-upper 60s well inland to low- mid 70s closer to the coast Monday night.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
Subsidence will continue to diminish aloft with retreating high pressure at the surface and aloft, and the environment will trend back towards a more typical summertime pattern, with isolated to scattered showers and thunderstorms during afternoon hours. Moisture is anticipated to stream into the region during the second half of the week as a low pressure disturbance approaches the Southeast United States and lingers off the east coast of Florida. The additional moisture will help to enhance afternoon showers and thunderstorms locally, especially across southeast GA later in the week. Temperatures are expected to remain near normal.

AVIATION /20Z SUNDAY THROUGH FRIDAY/
20Z Update: Mainly VFR. Isolated to scattered convection should stay inland of the TAF sites through early this evening.
Otherwise, gusty winds should persist until around sunset, then be light or calm overnight.

Extended Aviation Outlook: Prevailing VFR. Brief flight restrictions are possible in afternoon showers/thunderstorms Monday to Wednesday, especially at KSAV. Later in the week, chances of tempo flight restrictions increase at CHS/JZI/SAV terminals with showers and thunderstorms moving onshore.

MARINE
Tonight: A weak cold front will linger over the area this evening before slowly lifting back northward late. Sustained winds will be from the E 10-15 kt. Seas should average 2-3 ft.

Monday through Thursday: High pressure extending across the region from the north and weak coastal troughing developing just off the Southeast Coast will favor an enhanced pressure gradient across local waters early week. In general, east- northeast winds approaching 15-20 kt and seas building to 3-5 ft are likely through Monday, before 6 ft seas arrive across offshore Georgia waters Tuesday. A Small Craft Advisory will likely be initiated across offshore Georgia waters by the end of Tuesday. Heading through mid- week, high pressure and the coastal trough persists, but increasing swell energy ahead of Atlantic low pressure approaching eastern Florida and a prolonged fetch will support seas building across local waters while winds gust around 25 kts. Small Craft Advisories will likely be needed for all waters outside the CHS Harbor during the second half of the week with seas building as high as 6-9 ft across nearshore waters and 7-11 ft across offshore Georgia waters by Thursday.

Rip Currents: A Moderate Risk for rip currents will remain in place this evening and through Monday with increasing swells anticipated and the potential of ongoing rip currents being reported today. A Moderate Risk for rip currents will likely continue for all beaches midweek as well as swell energy continues to increase ahead of a low pressure approaching the Southeast United States late week.

CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...None.
