Area Forecast Discussion National Weather Service Charleston SC 1015 PM EDT Sat Jul 4 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 SUNDAY MORNING/. As of 1010 PM: I will updated to remove headlines for the Coastal Flood Advisory. The forecast remains on track. No additional changes needed with this updated package.

As of 835 PM: KCLX indicated that the sea breeze has pushed west of the forecast area, with no showers over the CWA. I will update the forecast to remove the mention of showers this evening and make minor temperature tweaks.

As of 6 PM: KCLX detected isolated showers along a sea breeze pushing inland across Berkeley and Dorchester Counties. The latest run of the HRRR indicates that a few showers will develop along the breeze across SE GA over the next hour or two. Given the state of the Cu field west of the sea breeze and latest radar trends, I will update the forecast to add SCHC PoPs to the forecast through the early evening.

Previous Discussion: A weak mid-level low will be over the Lower MS Valley, causing northwest flow overhead. At the surface, weak high pressure across our area will keep a stationary front located to our south. Though, models indicate moisture and some lift associated with the front should approach our southernmost locations late tonight. Hence, we have slight chance POPs for McIntosh County and vicinity. A rumble of thunder also isn't out of the question given the instability in place. But nothing severe. Elsewhere, plenty of dry air in place should lead to a rain free night. Otherwise, light onshore flow is expected to generate some low clouds later tonight. Though, these shouldn't cause visibility issues outside of the smoke from the fireworks. Lows will mostly be in the 70s.

SHORT TERM /6 AM SUNDAY 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 /02Z SUNDAY THROUGH THURSDAY/. VFR. Smoke from fireworks should remain localized and are not expected to impact the terminals.

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. Tonight: Weak high pressure over the area will keep a stationary front well to our south. The weak pressure gradient should keep sustained winds 10 kt or less. Seas will be 1-2 ft.

LONG TERM MARINE . 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.
