SYNOPSIS
Tropical low pressure will approach the Georgia and northeast Florida coast late today, then shift inland tonight. High pressure will then prevail into the middle of next week.

NEAR TERM /THROUGH TONIGHT/
No major changes were made for the noon update.

Today: Satellite, radar and reconnaissance data shows tropical low pressure centered about 130 miles southeast of Sapelo Island. The low appears to be embedded within a large envelope of PWATS in excess of 2 inches as noted by the latest GOES-E Total Precipitable Water product. Near term guidance is pretty unanimous in bringing the tropical low into the northeast Florida or far southern Georgia coast later tonight. As the low draws closer, this envelop of higher moisture will eventually more onshore later this afternoon bringing a distinct change in airmass, especially at the coast. Although the dry air will initially be hard to displace, PWATs are on track to surge later this afternoon into tonight nearing 2" by late afternoon as the coast. This increased moisture coupled with diurnal instability and increased coastal convergence will support an increase in precipitation this afternoon with scattered showers with a few tstms possible. Afternoon pops ranging from 20-30% inland (where drier air will have a greater influence) to 50% over the coastal counties looks reasonable given current trends. Highs from the lower 90s well inland to the lower-mid 80s at the beaches look on track. Breezy to locally windy conditions will linger along the coastal corridor, especially at the beaches.

Tonight: The remains of the Atlantic low will move into Southeast Georgia as an open wave. Elevated PWat and continued coastal convergence will allow for at least isolated to scattered showers and a few t-storms. The higher PoPs and greater QPF will be in closer proximity to the remains of the surface low. There is some evidence of low stratus forming over our northwest tier late, and perhaps resulting in some patchy fog. Lows will be a little warmer than recent nights with higher dew points and more of a southeast synoptic flow.

SHORT TERM /SATURDAY THROUGH MONDAY/
Saturday: The mid-levels will consist of broad High pressure over the Lower MS Valley, and a weak Low just offshore. The Low will shift towards the Southeast coast and weaken, pushing the High further to the west. At the surface, a remnant Low may be over or near our area in the morning. Though, it's expected to transition into a trough over the Southeast by the afternoon. Additionally, High pressure will be over Bermuda. There will be deep moisture across the region from the remnant Low. 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. Both the synoptic models and long range CAMs point to an active summertime pattern. Expect likely POPs across our GA counties in the afternoon, aided by the sea breeze, and chance POPs across our SC counties.
POPs will decrease in the evening and overnight, but remain in the chance category along the coast. We can't completely rule out a marginally severe thunderstorm with damaging winds. But the bigger concern will be the potential for locally heavy rainfall underneath the thunderstorms, especially given the weak steering flow and potential for training. Highs will be in the upper 80s to lower 90s.
Lows will generally be in the 70s.

Sunday: A weak mid-level Low offshore in the morning will get absorbed into the overall flow. Meanwhile, troughing will develop over the East Coast. Surface High pressure will be in the Atlantic with weak troughing over the Southeast. Deep moisture will persist across our area with PWATs exceeding 2". This remains well above normal for this time of year. Another active afternoon is expected with likely POPs across most of our area. Similar to Saturday, we can't completely rule out a marginally severe thunderstorm with damaging winds. But the bigger concern remains the potential for locally heavy rainfall underneath the thunderstorms due to the weak steering flow. The convection will decrease in both coverage and intensity during the evening and overnight. Highs will range from the upper 80s at the beaches to the lower to mid 90s elsewhere.
Additionally, heat indices should top the 100 degree mark before convection develops. Lows will generally be in the mid 70s.

Monday: The mid-levels will consist of a trough over the East Coast, gradually shifting offshore. 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 during the day. 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 may be a bigger concern with rising 850 mb temperatures and compression ahead of the front. Highs could peak in the mid to upper 90s, except cooler at the beaches. But dew points well into the 70s could cause heat indices to rise to 105-110 degrees, which could prompt coastal Heat Advisories. However, afternoon convection is expected to quickly develop, which would lower temperatures. This aspect of the forecast will need to be refined further.

LONG TERM /MONDAY NIGHT THROUGH THURSDAY/
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 forecast generally has POPs peaking in the afternoon and evening, then gradually transitioning them to favor the Atlantic coastal waters during the overnight hours. High temperatures will be well into the 90s. Heat indices could also rise to 105-110 degrees along the coast, which could prompt some Heat Advisories.

AVIATION /16Z FRIDAY THROUGH TUESDAY/
21/18z TAF Discussion: KCHS/KJZI/KSAV: Scattered showers could impact all three terminals this afternoon. Durations look to remain fairly brief so VCSH will be highlighted for all terminals. The risk for showers will linger at KCHS into early evening, KJZI through late evening and KSAV through the overnight as low pressure approaches the northeast Florida and far southern Georgia coast.
A more concentrated area of rain could approach KSAV as daybreak approaches, but this will be highly dependent on the track/intensity of the low as it treks onshore. VCSH was held for now. There could be brief stints of MVFR cigs just about anywhere this afternoon as showers push through. VFR should prevail for much of the period, however.

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

MARINE
Winds in the Charleston Harbor are running a tad higher than expected. A Small Craft Advisory has been issued until 4 PM for 15-20 kt with gusts to 25 kt.

Today: Tropical low pressure southeast of the Altamaha Sound will approach the coast this afternoon into tonight. There remains a decent gradient in place between that system and elongated high pressure to the north. Enough so that we still have Small Craft Advisories on all Atlantic waters, for E-NE winds of 15-20 kt and gusts near 25 kt. Seas are still elevated after several days of a persistent onshore wind, and are as high as 6 feet within 20 nm of shore, but up to 8 feet further out.
Charleston Harbor should not have as much wind as recently, but still up to 15 kt or occasionally 20 kt. Mariners can expect isolated to scattered t-storms developing today in response to the tropical system.

Tonight: The tropical low will become an open wave as it moves into southeast Georgia. The gradient eases, and we will start to see winds and eventually seas come down enough where we can drop the Small Craft Advisories.

Saturday through Tuesday: A typical summertime pattern is expected with High pressure in the Atlantic and occasional surface troughing over the Southeast. By Sunday, sustained winds will mainly be from the south or southwest, strongest along the land/sea interface with the formation of the afternoon sea breeze. Seas will average 2-4 ft.

Rip Currents: Persistent onshore flow and lingering elevated seas will again produce a High Risk of rip currents at all beaches today. Lifeguards continued to indicate hazardous swimming conditions at area beaches, and these conditions are expected to continue today. For Saturday, winds will stay onshore, but seas will trend lower. Therefore, we have a moderate risk of rip currents for all beaches.

TIDES/COASTAL FLOODING
Tide levels will continue to be elevated late this week thanks to persistent onshore flow and elevated seas. However, the astronomical tide values aren't particularly high, which will reduce the overall coastal flooding risk. The high tide this evening (~8:30 pm) in Charleston Harbor will likely fall short of when shallow coastal flooding begins. However, with the tropical disturbance moving in our general direction, but staying to the south, this puts the local area in a favorable position for potentially some higher surge moving in than the guidance would suggest.
