Synopsis for the coastal waters of south coastal south carolina and north coastal georgia.. High pressure will prevail inland today, while a stationary front lingers to the south. The front will lift back north into the area on Tuesday. Meanwhile, low pressure is expected to pass well off the southeast coast. A cold front will cross the region later in the week, then stall in the vicinity into the weekend.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kchs 260801 afdchs area forecast discussion national weather service charleston sc 401 am edt Mon aug 26 2019 Synopsis High pressure will prevail inland today, while a stationary front lingers to the south. The front will lift back north into the area on Tuesday. Meanwhile, low pressure is expected to pass well off the southeast coast. A cold front will cross the region later in the week, then stall in the vicinity into the weekend. Near term through tonight Today: we're off to another "cool" start with a high pressure wedge again anchored in place over the local area. Meanwhile, a stationary front found near the georgia florida border will lift a little northward late, while a broad and elongated low will be located about midway between savannah and bermuda as it drifts eastward. At the same time in the mid and upper levels, a trough will push east through the mississippi valley, while an anticyclone centered over southern florida pokes north over the local vicinity. There doesn't appear to be much chance of convective rains until maybe late in the day, with large subsidence in place and really no significant trigger other than the sea breeze. However, as we get into the evening, the stationary front will get some impetus to lift closer to our georgia counties, aided by the gulf sea breeze and short wave energy embedded in the upstream trough. We'll carry just 20% pop over parts of southeast georgia after 3-5 pm, where the best theta-e ridging and highest pwat will occur. Temps will be somewhat problematic, highly dependent upon the cloud cover, which looks to average 60-70% throughout. Our MAX temp forecast is a blend of the rap, hrrr and MOS guidance, which supports mid and upper 80s everywhere inland from the immediate shoreline. Tonight: the upstream trough dampens as it heads toward the area where mid and upper ridging persists. At the surface the inland wedge continues, while the atlantic low meanders several hundred miles east of charleston and the stationary front nudges a little closer from the south-southwest. A fairly decent band of convection near and along the front will make a run toward our southwest and west zones, but with the instability waning, we don't have anything more than isolated to scattered showers and maybe a few t-storms over our central and southern counties. The air mass becomes more modified, so it won't be quite as "cool" as this morning. Short term Tuesday through Thursday Surface high pressure extending down from the north will weaken on Tuesday as a stalled front south of the area lifts back north. A weak wave of low pressure looks to develop along the front which will then drift into the area Tuesday night. Concurrently, a dampening shortwave trough and associated vort energy will move across the region. It should be a fairly active day especially in the georgia zones. Further north, areas around the charleston tri- county could see very little precip. Rain chances will peak in the afternoon and evening hours, however some activity will likely persist into the overnight with the boundary low in the vicinity. On Wednesday, a cold front will approach from the west through the day, then cross the local area Wednesday night into early Thursday. Models are in good agreement that the front will stall near the coast and linger in the vicinity thereafter. Convection will be possible Wednesday ahead of the front as pwats surge. A stronger storm or two is possible, but with modest instability the widespread severe threat appears to be low. The proximity of the stalled front trough axis will determine rain chances on Thursday. For now, maintained chance (30-40%) pops with the gradient trending from lower inland to highest at the coast. Highs will be within a couple degrees of normal through the period, however temperatures will be warming each day. Lows will mainly be in the low to mid 70s. Long term Thursday night through Sunday Models are in fairly good agreement in the long term period. A stalled front will be meandering in the vicinity late week before |
largely dissipating. Weak high pressure should then prevail over the weekend. Persistent onshore flow will keep abundant moisture in place. This in combination with passing shortwave energy will support healthy shower and thunderstorm chances, mainly during the daytime hours. Seasonable temperatures are expected through the period. Aviation 07z Monday through Friday Vfr with prevail with the 06z forecast for ksav and kchs, although there could be a period of MVFR ceilings a couple of hours either side of daybreak as moisture gets trapped beneath the inversion. Extended aviation outlook: brief flight restrictions are possible with showers thunderstorms Tuesday through late week. Marine Today and tonight: the synoptic pattern features an inland high pressure wedge, a stationary front to the south, and low pressure to the east. This will result in a fairly tight pressure gradient this morning, and a continuation of the ongoing small craft advisories for both amz350 (for wind gusts as high as 25 kt) and for amz374 (for seas of 6 feet). The gradient relaxes enough this afternoon and tonight that winds and seas will gradually decrease, and no additional advisories will be necessary, even though the atlantic low could get a little better organized. Tuesday through Saturday: no marine concerns are expected through the period. High pressure to the north will weaken on Tuesday allowing winds to become more southeasterly. A cold front will approach from the west on Wednesday then enter the waters early Thursday. The front will linger in the vicinity late week before dissipating. The pattern will promote generally onshore flow late week into the weekend. Conditions will remain well below small craft advisory criteria with wind speeds of 15 knots or less, and seas 2 to 3 feet on average. Rip currents: increasing astronomical influence and onshore winds could contribute to an enhanced risk of rip currents on area beaches later this week. Tides coastal flooding Tide levels have responded to the more favorable northeast winds of yesterday and last night, which will continue today, leading to decent positive departures. The 5 pm high tide is a cause for concern in charleston harbor, as we will likely require a coastal flood advisory for shallow salt water flooding. Tide levels in the savannah fort pulaski area will not reach advisory levels with the late day high tide. Elevated tide levels are expected this week with the approach of the lunar perigee and new moon this Friday. Coastal flooding will be likely during the evening high tide cycles, especially during the latter half of the week. In addition, there is the potential for some heavy rain around the times of high tide which could exacerbate any flooding issues. Chs watches warnings advisories Ga... None. Sc... None. Marine...
