SYNOPSIS
Tropical low pressure will move onshore along the Northeast Florida and Southeast Georgia coast tonight. High pressure will then become the primary feature this weekend and into next week.

NEAR TERM /THROUGH SATURDAY/
The observed 0Z KCHS sounding observed CAPE between 2000 to 2500 J/kg and PWAT values around 2.2 inches. Recent radar trends indicate greater coverage over portions of the Charleston Tri- County area late this evening. The forecast update will indicate higher PoPs along the I-26 corridor through midnight.

As of 930 PM, regional radar indicated that the center of a well defined tropical low was 10 to 15 miles off the coast, near the FL/GA line. The center of the low is tracking towards the FL/GA coast; NHC indicates that probs of a tropical cyclone formation have decreased to 40 percent.

KCLX detected scattered to numerous showers across the forecast area, greatest near the coast. Recent runs of the HRRR indicate that the coverage of the inland showers will decrease through the rest of this evening. Recent SPC Mesoscale Analysis indicates CAPE values will remain above 1500 J/kg through midnight. This lingering instability should support scattered shower coverage this evening. After midnight, PW values will surge up to 2.2 to 2.4 inches, especially near the center of the tropical low. HRRR indicates that a band of numerous to widespread showers with embedded thunderstorms will develop near and just north of the low center late tonight into early Saturday morning. The combination of lingering instability and high PWAT should produce a corridor of moderate to even heavy rainfall south of the Savannah River. In fact, HRRR indicates the probabilities of the 3 hour QPF exceeding 1 inch may peak at 70% with 30% chance of 3 inches.

QPF was increased to over an inch in spots, primarily between McIntosh and Chatham Counties. Given the thick cloud cover and rounds of rain expected overnight temperatures were kept generally in the mid 70s. However the heavy rainfall over southeast GA could result in wet bulb cooling, resulting in some locations getting into the low 70s.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/
Saturday and Saturday night: Aloft, the forecast area will sit on the eastern extent of the upper ridge. At the surface, the main feature of interest will be the remnant circulation of the tropical disturbance that pushed inland along the northeast Florida and southeast Georgia coast. This circulation and the envelope of deep moisture associated with it will linger near the Georgia coast and will be the focus for thunderstorm activity likely ongoing at the start of the day. The highest rain chances and greatest coverage of thunderstorms is expected to be across the Georgia coastal waters, southeast Georgia, and up along the Savannah River into southeast South Carolina. Rain chances peak in the 60 percent range, but could certainly need to be higher depending on how things evolve overnight. This will yield the possibility of some locally heavy rainfall, given the presence of the circulation, deep moisture, and potential for training storms. For this highlighted area, rainfall amounts of 0.50-1.00" will be common, with potential for locally higher amounts. Overnight, while the focus for nocturnal convection should shift offshore, we could still see some showers and storms periodically attempt to push onshore. Though the highest chances are positioned over the waters, we do maintain 30-40 percent chances along the entire coast overnight. The presence of clouds and the expected convection should keep temperatures down a bit along the coast, with upper 80s common there.
However, further inland we could see some low 90s. Overnight, lows will be typical of summertime with low to mid 70s.

Sunday through Monday: On Sunday, the remnant circulation should completely dissipate or at least shift off to the northeast.
This should begin the transition to a more typical summertime pattern as the subtropical high takes hold with a lee trough inland across central Georgia and the Carolinas. Convection should become more diurnal each day, favoring the afternoon and evening time period. Temperatures will begin to increase as well, with Sunday highs in the mid to upper 90s inland and low 90s elsewhere. Then by Monday, look for mid to upper 90s across the entire forecast area. The result for Monday will be heat index values rising to around 105 for much of the forecast area.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Aloft, the pattern will transition to weak and broad troughing for much of the upcoming week. At the surface, the pattern should be typical of summertime with subtropical high pressure in control. Rain chances will be diurnal, with the highest chances in the afternoon and evening and then transitioning offshore to the coastal waters during the overnight periods. The most notable part of the forecast will be highs in the mid to upper 90s Tuesday and Wednesday, with a few inland locations possibly hitting triple digits. For Thursday, mid 90s should be more common then coming down to the low to mid 90s by Friday.
Depending on how dew point values work out, there could be some heat index values into the 105-110 degree range Tuesday- Thursday, primarily along the coastal corridor. If this comes to fruition, Heat Advisories could be needed.

AVIATION /02Z SATURDAY THROUGH WEDNESDAY/
Prior to the 0Z TAFs, KCLX detected shower activity near or over each terminal. Short duration restrictions are possible with the occurrence of showers this evening. The potential for MVFR conditions will be highlighted with a TEMPO from 0-4Z for KCHS and KJZI. A band of at least moderate showers with embedded thunderstorms is forecast to develop across the SE GA coast late tonight with the landfall of a tropical low. The axis of this convection will likely remain just south of KSAV. However, KSAV will remain close enough that it may experience period of MVFR conditions with showers between 5-9Z, highlighted with a TEMPO.
HRRR thunder probs increase significantly toward daybreak Sat across SE GA. In addition, forecast soundings and MOS indicate MVFR ceilings with restrictions to visibility during showers and thunderstorms. It appears that MVFR conditions will linger at KSAV through much of the day, ending around 20Z.

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

MARINE
Tonight: Winds are certainly over performing a bit across the coastal waters this afternoon with tropical low pressure located just to the southeast of the Georgia offshore waters.
Enhanced winds will linger into this evening then diminish a bit overnight as the low moves inland along the far northeast Florida or southern Georgia coast. Winds/seas will diminish first over the South Carolina waters, including Charleston Harbor, and the Georgia waters late. However, there is uncertainty on how quickly winds/seas will diminish, especially over the South Carolina waters. The Small Craft Advisory has been extended until 6 PM for the Charleston Harbor, 8 PM for the South Santee- Edisto Beach nearshore waters and into the overnight for the two Georgia marine legs. The highest seas will occur early this evening, 4-6 ft nearshore and 6-8 ft over the Georgia offshore waters.

Saturday through Wednesday: South to southwest flow mainly in the 10-15 knot range should prevail across the local waters through the weekend and into the middle of next week. The exception will be Sunday night into Monday when winds are expected to increase a bit as the gradient tightens, with 15-20 knots more common. Seas should average 2-4 feet through the period, though perhaps up to 5 feet at times in the outer waters as winds surge a bit.

Rip Currents: Onshore winds and lingering swell energy will help to keep the rip risk elevated Saturday and again Sunday. For Saturday, depending on the peak winds and the amount of swell that arrives at the beaches, the local rip current calculator results in a borderline high risk. Current approach is to maintain the moderate risk for Saturday and allow the overnight shift to re-evaluate.

CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...Small Craft Advisory until midnight EDT tonight for AMZ354.
Small Craft Advisory until 4 AM EDT Saturday for AMZ374.
