Area Forecast Discussion National Weather Service Charleston SC 1054 AM EDT Thu Apr 2 2020

SYNOPSIS. High pressure will prevail into early next week. A cold front will approach the region towards the middle of next week.

NEAR TERM /THROUGH TONIGHT/. Late this morning: A very quiet quiet and comfortable day on tap across southeast South Carolina and southeast Georgia. North to south oriented high pressure centered north of the Great Lakes will continue to extend into the forecast area. This setup will continue to drive north to northwest flow across the forecast area, but the gradient will be much more relaxed so overall wind speeds will be less than yesterday. More importantly, we have lost the plentiful low level moisture and the influence of the trough aloft so we are currently under clear skies. With unabated insolation, temperatures will be warmer than Wednesday. The KCHS 12z sounding recorded a 1000-850 mb thickness of 1335 which would give a high around 68. With weak downslope flow, we continue to think we will overperform this a bit. The forecast features 68-70 around the Tri-County, and roughly 70-73 across southeast Georgia.

Tonight: The synoptic pattern will change little with high pressure remaining anchored over the area. The boundary layer will decouple by mid-evening result in a calm/light wind field. The combination of clear skies and calm/light winds will yield strong radiational cooling and low end of the guidance envelop was utilized to construct low temperatures Friday morning. Some high clouds associated with a west-east oriented jet streak propagating along the Gulf Coast could work into areas south of the I-16 corridor right around daybreak, but this should not have an influence on overnight lows. Lows will range from the lower-mid 40s inland with upper 40s/lower 50s at the coast with lower-mid 50s at the beaches. There could be a few lower 40s in some of the normally cooler more sheltered areas such as the Francis Marion National Forecast.

SHORT TERM /FRIDAY THROUGH SUNDAY/. Friday through Sunday: High pressure will prevail through the period. The ridge axis will stay west of the area Friday into Saturday, before slowly shifting into the Atlantic later in the weekend. The weather will be quite pleasant with dry conditions and low humidity values. Developing return flow on Sunday will bring moisture levels up a bit, but will bring no more than an increase in cloud cover. Temperatures will be seasonable.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/. Atlantic high pressure will be the dominant feature on Monday, with a dry forecast to continue. High pressure will then weaken as low pressure and an associated cold front moves into the eastern U.S. towards the middle of the week. Differences exist between model solutions regarding details, but moisture will increase and a stream of shortwave energy is progged to pass through, so rain chances will return. PoPs are held in the chance range. Temperatures will be above normal through the period.

AVIATION /15Z THURSDAY THROUGH MONDAY/. VFR. Winds could get a little gusty during peak heating, but no major impacts are expected.

Extended Aviation Outlook: VFR is expected to prevail into early next week.

MARINE. Through Tonight: There are no concerns. A northwest wind regime will dominate with high pressure centered to the west. There are signs that an ill-defined sea breeze circulation could form along the middle and southern Georgia coast later this afternoon resulting in a weak, somewhat chaotic wind field over the Georgia nearshore leg. Otherwise, winds will average 10 kt or less today with 10-15 kt tonight. Seas will range from 1-2 ft nearshore waters and 2-4 ft over the Georgia offshore waters through tonight. A period of 4-5 ft seas are expected to impact the far eastern portions of the Georgia offshore leg (mainly 50-60 NM) through this afternoon.

Friday through Tuesday: High pressure will prevail into early next week. Winds will gradually become more onshore through the weekend as the ridge axis slides into the Atlantic. Conditions are expected to stay below Small Craft Advisory criteria, although 6 foot seas could enter the far outer portions of the Outer Georgia waters late weekend.

TIDES/COASTAL FLOODING. Elevated tide levels are expected next week due to astronomical influences from the upcoming full moon and lunar perigee. Minor saltwater flooding will be possible around the times of high tide, especially each evening.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
