SYNOPSIS
An area of low pressure and associated front will pass through the area and offshore tonight through Sunday. Dry high pressure will return to the region early next week and prevail into the middle of the week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
KCLX shows a southward moving outflow boundary moving into Berkeley County, generated by convection over the Pee Dee. This feature has the best chance for producing showers/tstms over the next few hours, mainly form Colleton County north to the Santee River. South of this area, the atmosphere caps off pretty quickly. Pops were reoriented to better reflect this.
Temperatures are proving tricky with the cold front still well to the north. Lows from the lower 60s well inland to the upper 60s at the beaches were maintained, although many areas may very well end up a few degrees warmer than that with a slower southward progression of the cold front expected.

SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/
Sunday and Sunday night: A tricky forecast as the cold front will be situated directly across the forecast area from west-southwest to east-northeast. The first part of the day should be in a relative lull for showers and/or thunderstorms in the wake of departed early Sunday morning convection. The front will slowly sag southward across the area through the day and increased rain chances are expected for the afternoon and especially into the evening as the area gets into the cool side of the low and the front. While there could be a few hours of sufficient instability for thunderstorms in the morning just about anywhere, the risk area will steadily shrink southward to primarily include the I-16 corridor and south including Jasper and Beaufort counties. The greatest coverage of mostly showers will track across the area from the late afternoon through the late evening hours and that is when we have the highest rain chances in place. Overall, the severe threat is low as the best instability is progged to retreat southward before the arrival of the better forcing. However, it's not out of the question to see a couple of stronger storms across our far south including McIntosh, Long, Liberty, and Bryan counties in the late afternoon and early evening hours. Daytime highs will be quite the forecast challenge thanks to the presence of the front and anticipated north to south gradient. Inland areas across Millen to Allendale and Moncks Corner might only reach the mid 60s while locations around Savannah, Hinesville, and Darien reach the low to mid 80s. Overnight should be mostly dry with the low and front situated offshore. Lows are forecast to cool into the upper 40s inland and the low 50s closer to the coast.

Monday through Tuesday: Monday will bring a seasonally cool day as the area is situated between the high to the west and the low center and associated front offshore. This setup will drive cool northeast flow across the area and some model guidance that there will be enough residual moisture to produce some light rain showers Monday morning and early afternoon. We have kept 20 percent rain chances for much of the day, mostly along the coastal corridor. Cloud skies in the morning should start clearing from the west in the afternoon.
Temperatures will be the main story, with highs only topping out in the mid to upper 60s which would be on the order of 11-13 degrees below normal for the date. Then for Tuesday, high pressure settles in across the area and temperatures are expected to rebound nicely back into the mid 70s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Overall, the long term forecast period looks to be quiet with temperatures rebounding to be back above normal for most of the period. High pressure will be the primary feature during the period, though what looks like a dry front will drop through from the north during the Wednesday night-Thursday period.

AVIATION /06Z SUNDAY THROUGH THURSDAY/
21/06z TAF Discussion: KCHS/KJZI: Southward moving outflow boundary will cross the terminals around 06z, resulting in either a variable or northerly wind direction. This feature could produce a few showers/tstms through about 08z, but the atmosphere is capping off pretty quick ahead of the boundary. The risk for low clouds appears to be delayed with the front still well to the north and expected to progress much slower than expected. MVFR cigs are anticipated by mid-morning with the risk for showers increasing by early afternoon. IFR cigs with showers impacts will be possible 20-23z, so TEMPO groups were utilized to account for this at both sites. Widespread IFR cigs are expected from late afternoon through the remainder of the 06z TAF period.

KSAV: VFR will dominate through late morning with the approaching cold front expected to remain to the north through then. Showers/tstms will increase ahead of the front, which could impact the terminal 19-22z. A TEMPO group for MVFR vsbys/cigs in TSRA was utilized to account for this. Showers may linger near the terminal through about 00z which should end as the front passes through. Widespread IFR cigs are expected from roughly sunset through the remainder of the 06z TAF period.

Extended Aviation Outlook: Flight restrictions will likely linger across the area from Sunday evening through the first part of Monday before improving. VFR thereafter.

MARINE
Tonight: A cold front will slowly sink to the south and southeast through the night, reaching into the Charleston County waters late. In advance of the front SW winds will reach as high as 15 or 20 kt, then winds clock around to the W south of the front, maybe around to the NW and N on the Charleston waters late, with speeds dropping to about 10 kt or under. Seas will average 2 or 3 feet. Mariners should remain alert for some t-storms developing on the Charleston County waters after midnight. Wind gusts of 30 or 35 kt and frequent lightning can occur with some of these storms.

Sunday through Thursday: Winds will start to surge out of the north Sunday afternoon as a front clears through the waters. Northeast flow will then strengthen Sunday night through most of Monday and Small Craft Advisories will very likely be needed for all the local waters. Conditions will then steadily improve through Tuesday with no forecast concerns through the end of the forecast period.
