Area Forecast Discussion National Weather Service Charleston SC 344 PM EST Sat Dec 7 2024
SYNOPSIS
High pressure will prevail through early next week, before a cold front impacts the area midweek. High pressure will return for late week.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
The mid-levels consist of WNW flow over our region. Heights should gradually rise into the night. At the surface, High pressure over the Deep South late this afternoon will move closer, likely being centered just south of our region late tonight. The High will dominate our weather, bringing dry conditions. The 12Z CHS sounding only had a PWAT of 0.16", which is extremely dry for this time of year. However, PWATs should gradually rise to above 0.5" overnight, leading to rising dew points. A very modest uptick in mid/high level clouds are expected tonight. Lows should be a little milder, ranging from the upper 20s to lower 30s inland, and warmer along the immediate coast.
SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/
High pressure will slip offshore on Sunday, while mid level ridge briefly passes overhead. Quiet and dry weather is expected with temperatures warming back to near normal levels in the mid 60s. Lows Sunday night will be more mild than previous nights, largely in the mid to upper 40s.
High pressure will continue to extend into the area Monday and Tuesday but will weaken in advance of an approaching cold front.
The pattern aloft will feature a series of shortwaves lifting across the region out of southwest flow. Coincident with the arrival of deeper moisture, rain chances will be on the increase later Monday into Tuesday, particularly over inland locations.
PoPs generally peak in the 30-60% range. Temperatures will continue to warm, topping out ~10 degrees above normal in the mid 70s across most locations on Tuesday. Lows Monday night will only fall to the mid/upper 50s.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
The weather will be most active Tuesday night into Wednesday as a cold front pushes across the area and eventually offshore by Wednesday afternoon. Showers are expected to accompany the front, with perhaps an embedded thunderstorm or two however instability progs are rather meager so the forecast excludes mention of thunder at this time. This system should bring more significant rainfall than we've seen in awhile. Given how dry it has been, no flooding concerns are anticipated. Rain chances will quickly diminish post- fropa later Wednesday and Wednesday night with a dry forecast in place for the rest of the week as high pressure returns. Cooler temperatures will return for late week.
AVIATION /20Z SATURDAY THROUGH THURSDAY/
18Z TAFs: VFR.
Extended Aviation Outlook: Flight restrictions are possible in showers associated with a cold front Tuesday night into Wednesday. Gusty winds are also possible on Wednesday.
MARINE
Tonight: Surface High pressure over the Deep South late this afternoon will move closer, likely being centered just south of our region late. Winds will turn to the SW and increase during the evening, becoming sustained 10-15 kt overnight. Seas will average 2-3 ft.
Sunday through Thursday: Southwest to south flow will prevail through early week as high pressure slips offshore and a cold front advances towards the area. No marine concerns/headlines are anticipated through Tuesday, with speeds generally 15 knots or less and seas averaging 2-3 feet. Winds and seas will build Tuesday night ahead of the aforementioned front and will remain elevated through Wednesday night following fropa Wednesday afternoon. Small Craft Advisories are likely for most, if not all, marine zones. Conditions are expected to improve Thursday as high pressure expands over the waters and the pressure gradient eases.
