SYNOPSIS
Tropical Low pressure will move onshore along the Southeast Georgia coast today. A typical summertime pattern with diurnal convection is expected next week.

NEAR TERM /THROUGH TONIGHT/
Satellite imagery and radar data reveals the tropical low center has nudged slightly inland into Glynn/Camden counties with a couple of pronounced feeder bands arcing from the outer Georgia waters into southeast Georgia up to around the Savannah River entrance. Convection has displayed an uptick over the last few hours with a corridor of lightning just outside the outer waters. SPC mesoanalysis continues to show MLCAPE values running 1-2K J/Kg in the coastal waters, a small core of >40 knots effective bulk shear near the eastern flank of the low, and a small core of high values of non- supercell tornado parameter. Still keeping an eye out for any signs of waterspout development as we head into the morning hours.

High- res guidance suggest the tropical low will edge inland a bit today while weakening, although meander up the coast through tonight. Precip chances with the low and rainfall amounts are the main forecast challenges.

Today: Primary focus for showers is looking to largely remain through the coastal areas of southeast Georgia and just into coastal areas of South Carolina through the early-mid morning hours. But with heating, inland and a northward expansion of showers and some thunderstorms is anticipated from late morning and into the afternoon. Forecast will feature the highest overall precip chances and rainfall amounts across coastal southeast Georgia into a portion of coastal southeast South Carolina where, given the elevated PWAT values/envelope of deep moisture with the low and potential for training convection, rainfall amounts of 1 to 2 inches is a good bet through today. HRRR precip probabilities do suggest roughly a 30-50 percent probability of 3 inches along portions of the coast south of Savannah. However, no hydro related products are anticipated at this time. Highs today will range from the upper 80s to the lower 90s...tempered a bit along the coast by passing convection.

Tonight: Diurnally driven/enhanced convection should diminish.
However, remnant tropical low will continue to meander up the coast and may drive additional showers and some thunderstorms up through the SC coastal waters, some of which might skirt the South Carolina coastal areas. Forecast will feature chance to likely pops along the coast with diminishing precip chances inland. Some locally heavy rainfall will remain a possibility right along the SC coast. Lows tonight dip into the lower to middle 70s.

SHORT TERM /SUNDAY THROUGH TUESDAY/
Sunday: A weak mid-level Low will be located just offshore in the morning, quickly getting absorbed into the overall flow. Meanwhile, troughing will develop over the East Coast, especially to our north.
Surface High pressure will be centered near Bermuda while troughing persists over the Southeast. Deep moisture will continue to persist across the region. PWATs across our area should exceed 2", which is above the 90% mark for CHS per SPC Sounding Climatology and nearly 2 standard deviations per NAEFs. The synoptic models and long range CAMs indicate an active convective pattern. Therefore, we have likely POPs across our coastal counties in the afternoon, aided by the sea breeze. POPs will decrease in the evening and overnight, with most areas becoming dry after midnight. There is decent instability, so we can't completely rule out a stronger or marginally severe thunderstorm with damaging winds. However, the bigger concern is the potential for locally heavy rainfall underneath the thunderstorms. This is due to the abundant moisture and weak steering flow. So flooding in low-lying and poorly drained areas is possible. Highs will range from the upper 80s at the beaches to the lower to mid 90s further inland. Additionally, heat indices should peak in the lower 100s before convection develops.
Lows will mostly be in the mid 70s.

Monday: The mid-levels will consist of a trough initially over the East Coast. It'll gradually shift offshore as time progresses.
Meanwhile, broad High pressure centered over the Southern Plains will creep it's way towards our region. At the surface, troughing will be over the Southeast in the morning, with High pressure in the Atlantic. A cold front will approach from the north, reaching just north of our area late at night. The deepest moisture appears to get pushed offshore in advance of the front, with the 2+" PWATs off our coast. However, PWATs ~1.75" will remain across our area. The heat should be the main concern due to 850 mb temperatures, low-level thickness values, and compression ahead of the front. Highs could peak in the mid to maybe upper 90s, except cooler at the beaches.
But dew points rising into the 70s near the coast will cause heat indices to rise to ~105 degrees. This is just short of Heat Advisory criteria. Additionally, afternoon convection is expected to quickly develop along the sea breeze and ahead of the approaching front.
This will lower temperatures and heat indices. We have chance POPs in the afternoon. While a stronger storm with gusty winds is possible just about anywhere, the bigger concern will be the potential for locally heavy rainfall underneath the thunderstorms.
Though, steering flow should be a little stronger, which would limit QPF if no training develops. Convection will gradually decrease during the evening and overnight. Lows will generally be in the 70s.

Tuesday: Mid-level troughing offshore will shift away as broad High pressure centered over the Southern Plains tries to make its way towards our region. A cold front located just to our north at daybreak should slowly shift southward. It's expected to stall across our area and then weaken. The highest PWATs appear to be located south and offshore of our area. Once again, the heat will be the main concern. Highs are expected to reach the upper 90s to around 100 degrees across most of our area, except cooler at the beaches. Dew points well into the 70s near the coast will cause heat indices to rise to 105-110 degrees. Coastal Heat Advisories are possible. But similar to Monday, afternoon convection is expected to quickly develop, which will lower temperatures and heat indices.
Otherwise, we have chance POPs.

LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/
Weak mid-level troughing will occasionally be over the East Coast.
Surface troughing or weak fronts will be impacting the Southeast U.S. while High pressure is near Bermuda. This summertime pattern will yield diurnal convection. The highest POPs are each afternoon and evening, then trending lower overnight. High temperatures will be well into the 90s each day. Heat indices could also rise to 105- 110 degrees along the coast Wednesday and Thursday, which could prompt Heat Advisories.

AVIATION /07Z SATURDAY THROUGH WEDNESDAY/
Tropical low pressure near the southeast Georgia/northern Florida border will drift along the southeast Georgia coast through today. This will bring rather unsettled conditions to the region, particularly to the KSAV terminal overnight and through most of Saturday...with periodic MVFR conditions anticipated. We cannot rule out the possibility of some thunderstorms impacting the KSAV terminal, particularly during the day Saturday into Saturday night although overall probabilities are not great. We have elected to not include TSTMs with the 06Z forecast and will amend as needed.

KCHS/KJZI will be a bit less impacted. But shower activity should ramp up in and around the terminals during the afternoon timeframe and could bring brief MVFR restrictions.

Extended Aviation Outlook: Mostly VFR. However, convection will bring brief flight restrictions, mainly each afternoon and evening.

MARINE
Southeast flow will prevail across the coastal waters today.
Winds may be locally gusty south of the Savannah River, although gusts and seas will largely remain below Small Craft Advisory criteria with gusts to around 20 knots and seas 4 to 5 feet.
Winds and seas across the South Carolina coastal waters will run a touch lower.

Extended Marine: A typical summertime pattern is expected with High pressure in the Atlantic and occasional surface troughing over the Southeast. On Sunday sustained winds will mainly be from the south or southwest. Though, they are expected to surge from the SW in the evening and overnight. Gusts could approach 25 kt and we can't rule out Small Craft Advisories for our ocean zones during this time period. Otherwise, each day expect gradually backing winds. They'll be strongest along the land/sea interface and the Charleston Harbor with the formation of the afternoon sea breeze. Each night, winds will gradually veer.
Seas will average 2-4 ft.

Rip Currents: Onshore winds and swell energy will keep the rip current risk elevated today. Depending on the peak winds and the amount of swell that arrives at the beaches, the local rip current calculator results in a solid moderate risk and just below high risk. Will maintain a moderate risk with the morning forecast at this juncture.

Sunday: Winds will mainly be from the south, with a SE swell slowly trending lower. This will cause a Moderate Risk of rip currents to persist for all of our beaches.

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