SYNOPSIS. A cold front will approach the region by the middle of this week. The front should stall south of the region though late week.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Late Monday evening: Multicell thunderstorms advancing through the SC Midlands toward the southeast should hold together for a few more hours and could clip northern sections of Colleton, Dorchester and Berkeley Counties after 11 pm. Upstream radar trends, MLCape values 1500-2000 J/kg and downdraft CAPE values exceeding 1000 J/kg suggest some potential for gusty winds and small hail across northern/inland sections, and brief/isolated damaging wind gusts and quarter sized hail cannot be ruled out. Due to the ongoing potential for thunderstorms to just bypass inland areas, limited PoPs to chance/slight chance, highest across northern Berkeley County tapered to around 15 percent along the Colleton/Allendale line. PoPs farther down Interstate 26 remain below 15 percent with no mention of showers/ thunderstorms, but we will continue to assess trends as outflow from ongoing convection could support new convection farther south/west.
After midnight, any thunderstorms should either move out of northern/inland counties or dissipate. Ahead of a cold front approaching the area from the west, southwest winds should help hold temperatures in the 70s overnight. Patchy ground fog is possible, but potential coverage/impact does not justify a mention in public forecasts.
SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. Tuesday: A cold front will approach the region in the afternoon hours. A mid-level shortwave, in addition to some right-entrance region jet dynamics, will provide a lifting mechanism for possible convection. However, convection may have a hard time firing off given the lack of deep layered moisture. Westerly flow will most likely keep the sea breeze pinned at the coast until after sunset, especially along coastal GA. The greatest chance for convection will be in the Charleston Tri County, where there are decent CAPE values and the sea breeze has a chance to move inland during daylight hours. There is a risk that we could see an isolated severe thunderstorm, with damaging winds and hail as the main threats. High temperatures Tuesday will reach into the low to mid 90s inland and upper 80s at the coast, with upper 60s inland to low 70s at the coast overnight.
Wednesday and Thursday: The cold front will stall to the south on Wednesday before moving further offshore Thursday. Behind the front will be much drier air, with some dew points only reaching into the 50s in inland GA. Forecast soundings show a significant cap over the region on both Wednesday and Thursday, limiting any shower/thunderstorm potential. Highs will be slightly cooler, with upper 80s to low 90s expected both days inland with mid to upper 80s at the coast.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. High pressure will prevail over the region Thursday into the weekend. Low pressure (currently located near the Bay of Campeche) and its associated deep moisture are expected to shift northeast from the Gulf of Mexico. This system has the potential to bring rainfall to the region, beginning Saturday afternoon and through Monday. There are still many uncertain details associated with this period and the aforementioned low pressure. High temperatures will be in the low to mid 90s inland and upper 80s along the coast. Low temperatures will be in the low 70s inland and mid 70s at the coast.
AVIATION /02Z TUESDAY THROUGH SATURDAY/. Patchy ground fog could develop later tonight into early Tuesday. Also, thunderstorms could pass north of KCHS during the 3-6z time frame tonight, and thunderstorms could impact terminals, especially KCHS, Tuesday afternoon. However, the probability for any of these events remains too low to justify any mention within 0z VFR TAFs.
Extended Aviation Outlook: VFR.
MARINE. Tonight: Ahead of an approaching cold front, south winds should veer to the southwest and average 10-15 knots with occasional gusts as high as 20 kt through the overnight. Seas will average 2-4 feet, highest beyond 20 nm.
Tuesday through Saturday: A mid-level shortwave trough is forecast to form a low pressure off the GA coast Tuesday evening, along with a low-level jet due to a tightening pressure gradient. Small Craft Advisories could be needed for the GA waters for 25 knot wind gusts, especially 20-60nm where seas are forecast to reach 6ft as well. Thereafter, winds generally 5 to 10 knots with seas 2 to 3 feet.
TIDES/COASTAL FLOODING. Coastal Flooding: The late evening high tide is expected to remain just below 7 ft MLLW in Charleston Harbor, so a Coastal Flood Advisory will not be needed.
