Area Forecast Discussion National Weather Service Charleston SC 200 AM EDT Fri May 17 2024
SYNOPSIS
High pressure will persist into Friday. A storm system will affect the area this weekend, followed by high pressure from the north next week.
NEAR TERM /UNTIL 6 AM THIS MORNING/
High pressure will prevail across the local area with a mid-lvl ridge axis also placed across the Southeast United States in advance of an MCS tracking across the Deep South. A fair amount of radiational cooling will take place ahead of the MCS during the night, resulting in calm winds and low temps that range in the low- mid 60s inland to upper 60s/around 70 near the coast. However, mid- high level clouds will likely increase from the west a few hours prior to daybreak as the MCS presses eastward, limiting further cooling potential. The decaying MCS will attempt to make way to far inland zones around daybreak, but any shower/thunderstorm activity will likely occur after 6 AM. As a result, a dry forecast will remain through the remainder of the night.
SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY/
A potent shortwave will spread extensive mid and high clouds over the area on Friday. Nevertheless, warm thicknesses should support high temps pushing into the mid/upper 80s. Some drier air is expected to mix down across inland areas with surface dewpoints dropping into the lower 60s Friday afternoon. Much of the guidance including synoptic scale models and CAMs show a decaying MCS moving into our far western zones late Friday afternoon. The best instability is forecast to remain just south of the forecast area Friday afternoon/evening.
A warm front will lift north through the area Friday night, with scattered showers and isolated thunderstorms possible through the night. Saturday an increasing SW flow will bring >1.7" PWATs into the area ahead of a longwave upper trough. There are some hints that after warm frontal precipitation lifts north of the area by mid Saturday morning, much of the day could be relatively rain-free. A series of shortwaves will then move through late Saturday afternoon through Saturday night, bringing numerous to widespread showers and thunderstorms. The greatest chance for severe thunderstorms will be Saturday afternoon during which the strongest instability will be present. Most guidance shows at least 1500 J/kg SBCAPE across the area and 50 kt bulk shear. This would support some storm organization with a damaging wind threat. Forecast LIs <-7C would also support large hail.
Plenty of moisture is expected to remain over the area through Sunday as a cold front drops in from the NW, then the upper trough axis swings through. Showers and thunderstorms are likely to persist through the day. Isolated severe thunderstorms could be possible due to decent instability ahead of the front.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
Isolated showers and thunderstorms will be possible through Monday due to moisture and forcing on the western periphery of the developing surface low off the NC/SC coast. Temperatures will be considerably cooler due to cold advection as high pressure builds from the north. The cooler weather will be short-lived as the surface high shifts southeast and a southerly flow redevelops. A few showers will be possible Wednesday as a shortwave moves through.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
VFR conditions are expected to prevail at CHS/JZI/SAV terminal through 06Z Saturday. However, the remnants of an MCS will impact the area, with the potential for SHRA/TSRA at the terminals (highest chances at SAV). For now, VCSH remains in the TAF for SAV starting around 15Z. Adjustments will likely be needed with later TAF issuances to account for timing/occurrence of the event.
Extended Aviation Outlook: Showers and thunderstorms could bring flight restrictions to all terminals Saturday through Sunday as a low pressure system impacts the region.
MARINE
Tonight: High pressure will remain across local waters resulting in no marine concerns through daybreak. In general, south/southwest winds will be around 10 kt or less. Seas will range between 1-2 ft.
Friday through Tuesday: Conditions through the period are expected to remain below Small Craft Advisory criteria.
Southerly flow will persist through Sunday, then the winds turn northerly behind a cold front early next week. Wind gusts could approach 25 kt late Sunday night into Monday morning with an initial burst of cold advection, mainly over the Charleston County nearshore waters.
