Area Forecast Discussion National Weather Service Charleston SC 120 AM EDT Sun Jul 5 2020

SYNOPSIS. A stationary front will linger south of the area through the weekend, then lift back northward by early next week. Low pressure will then bring unsettled weather to the region for much of next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. radar is starting to depict a few showers starting to develop in the nearby Atlantic just south of the forecast area, and this activity will eventually increase in coverage and start moving onshore of southeast Georgia during the late night and pre-dawn hours with increasing low level convergence and isentropic ascent. We have 20% PoP as a result over Liberty, Long and McIntosh County through 6 am. Skies will range from mostly clear north to partly cloudy central zones, with partly to mostly cloudy conditions south. Areas of stratus along parts of the west-northwest tier closer to daybreak will result in minor reductions in visibility. Min temps will generally be 70-75F, except for a few upper 60s in the Francis Marion National Forest, with a few upper 70s along the immediate coast and in downtown Charleston.

SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/. All models continue to indicate a more active/unsettled pattern to develop during this period. A broad upper low over the lower MS River valley will slowly move northeastward toward the region through early next week. As this system moves toward the area, it brings higher values of deep layer moisture and instability. This will result in an increasing trend in PoPs.

Sunday will begin the transition toward increasing PoPs, starting from south to north. Have kept chance PoPs mainly over the GA region. Monday and Tuesday, models continue to go likely to categorical PoPs. A little uncomfortable going with likely to categorical PoPs that far out, but models have been consistently trending in that direction for the last several runs. Rainfall totals through Tuesday expected to be 1-2 inches south of the Savannah River, and 1/2-1 inch north of the river.

High temperatures are expected to be near normal on Sunday, then slightly below normal for Monday and Tuesday due to increased cloud cover and PoPs. Lows in the lower to mid 70s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Low pressure is forecast to linger in the region mid to late week. There are still large discrepancies between models regarding the position and evolution of the low, however the overall pattern favors higher than normal rain chances, especially during the mid- week time frame. High temperatures will average slightly cooler than normal, while lows stay a couple degrees above normal.

AVIATION /06Z SUNDAY THROUGH THURSDAY/. KCHS: VFR conditions will prevail through 06Z Monday, with any flight restrictions in light fog to stay inland from the airfield.

KSAV: A stationary front to the south will weaken as it lifts north today and tonight, leading to an increase in clouds, lowering ceilings and at least a chance of SHRA/TSRA. While there could be occasional flight restrictions in light fog during the pre-dawn, and again during the late morning into tonight due to convection, we feel more confident in showing VFR conditions with the 06Z TAF.

Extended Aviation Outlook: Sunday: Mainly VFR conditions expected. Monday through Thursday: Periods of flight restrictions likely, especially during the afternoon/early evening within scattered to numerous showers and thunderstorms.

MARINE. Overnight: Weak high pressure over the area will keep a stationary front well to our south. The weak pressure gradient will generate SE through SW winds at or below about 8-12 kt. Seas will be 1-2 ft.

Sunday through Thursday . No highlights expected Sunday through Wednesday with generally southerly winds of 15 knots or less and seas 3 feet or less. Scattered to numerous showers and thunderstorms expected. Models indicate a developing surface low later Wednesday and Thursday, possibly tracking inland/well west of the waters. The track and intensity of this low pressure system will impact how strong the winds will get. Right now, the latest model trends indicate southwesterly winds by Thursday, possibly increasing to the 15 to 20 knots. However, due to uncertainty, the forecast for this period was left unchanged.

TIDES/COASTAL FLOODING. Astronomical influences will maintain higher than normal tide levels into early next week. Minor coastal flooding will be possible around the time of the evening high tides, primarily along the South Carolina coast. In addition, the risk for heavy rain early next week will only add to any tidal flooding.

CHS WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None. MARINE . None.
