Area Forecast Discussion National Weather Service Charleston SC 807 PM EDT Sun Apr 5 2020

SYNOPSIS. High pressure will prevail for the first half of this week. A cold front is expected to move through the region towards the end of the week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Update: The main change was to cancel the Coastal Flood Advisory for Charleston county. Tide levels at the CHS gauge remained just below minimum coastal flood criteria of 7 ft MLLW.

Tonight: Showers have dissipated across SE GA. Expect light winds and mostly clear skies to develop across the region by later this evening. Moist low level, especially areas in GA that received rainfall earlier today, should support radiation fog overnight. Confidence is still not high for widespread dense fog. However, locally dense ground fog could develop especially across SE GA where rain fell Sunday afternoon. Lows will range from the lower/middle 50s inland to the upper 50s/lower 60s near the coast.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/. The general overview during the first half of the week depicts a low amplitude ridge that will extend across the Gulf of Mexico into much of the southern states from Texas to the local area. Embedded within the resulting west-northwest flow aloft will be periodic short waves that will move over or near the immediate vicinity. That along with the sub-tropical upper jet that resides atop or close to the area, will supply enough forcing for at least some convection, mainly diurnal in nature each day. Meanwhile, surface high pressure initially overhead Monday and Tuesday will start to shift southeast Wednesday in advance of an upstream cold front and pre-frontal trough.

For Monday we are showing slight chance PoP across our South Carolina counties in closer proximity to a weak surface trough to the lee of the mountains, aided by the resultant sea breeze. There was some t-storms locally on Sunday, despite little instability, so we did consider adding t-storms Monday, but since there is some guidance suggestive of nothing reaching the area, we held off at this time.

On Tuesday, moisture profiles are the deepest, with the resulting pWat on the order of 1.4 to 1.6 inches. This moisture will have a better looking short wave that moves in during peak heating, and that along with the sea breeze and a nearby Piedmont trough will be enough for isolated to scattered PoP, highest of 30-40% along the north and northwest counties. There is actually a little "better" instability than recent days, so we did include a mention of t- storms for the afternoon.

Then during Wednesday, the moisture profiles are less and the sea breeze will be less of a factor with a deep offshore flow, even within much of the boundary layer. So for that reason we don't want to go any higher than 20/30% chances. Despite this, instability is even more than on Tuesday, with MUCAPE as high as 500 J/kg and LI's as low as -3 to -4C. Thus we feel compelled to maintain a mention of t-storms.

Temps Monday and Tuesday look to reach the lower or middle 80s inland from the coast, with Wednesday the warmest day of the short term period, with mid and upper 80s more common. If convection is delayed enough or turns out less in coverage, thickness values support around 90F in some places with the deep downslope flow. Night time lows will average far above climo.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. A cold front will slowly approach from the northwest during the middle the week, moving through sometime during the second half of the week. Models still vary on exactly when the front will move through, and the resulting weather before and afterwards. Again, we were forced to go with a blend of the models with POPs no higher than chance. Temperatures will be above normal Thursday, cooling down afterwards.

AVIATION /00Z MONDAY THROUGH FRIDAY/. VFR through about 08Z at both KSAV and KCHS. Then between 08-14z, the probability for stratus/fog will increase, especially at KSAV. Latest TAF still indicate a period of IFR visibility, with LIFR ceilings/visibilities possible. Probabilities for flight restrictions are lower at KCHS late tonight/early Monday, so the latest TAFs maintain VFR conditions. However, this remains a low confidence forecast. Remain alert for changes to introduce flight restrictions within later KCHS TAFs.

Extended Aviation Outlook: VFR Monday afternoon. Gusty winds possible at times Tuesday and Wednesday afternoon. Showers could bring brief flight restrictions each afternoon from Tuesday through Friday.

MARINE. Tonight: High pressure centered north of the region will maintain east to southeast winds 10-15 kt this evening, then winds should veer toward the south and diminish around 5 kt overnight. Seas will average 1-3 ft nearshore waters and 3-5 ft Georgia offshore waters, mainly in an east-northeast swell.

Monday through Friday night: Atlantic high pressure that encompasses the waters Monday and Tuesday, will shift further southeast during mid week in advance of the next cold front that looks to move in by late week. If there is any chance of Small Craft Advisory conditions, it would be Tuesday and Tuesday night on the AMZ350 waters and maybe in Charleston harbor Tuesday and Wednesday afternoon where sea breeze influences will enhance the wind fields.

Rip Currents: Given the strong influences of the upcoming full moon and perigee, plus small swells and sea breeze circulations, we have shown a Moderate Risk of rip currents at area beaches for both Monday and Tuesday.

TIDES/COASTAL FLOODING. Higher than normal tides are expected most of this week due to astronomical influences from the upcoming full moon and lunar perigee. Additionally, winds are forecasted to be onshore at times, and small swells will also occur, which would further elevate the tides. As a result, minor coastal flooding is likely through Tuesday, with minor to perhaps moderate coastal flooding during the mid and late week. Additional Coastal Flood Advisories will be required.
