1008am EST Tuesday Nov 29 2022

High pressure today will give way to a passing cold front that will move offshore Wednesday night. High pressure will then return late week before another cold front likely impacts the area this weekend and early next week.

Only made some minor adjustments to the hourly temperature curve to fit with the current diurnal trends. Otherwise, no other changes coming down the track in the mid-morning forecast update.

Near Term - Through Tonight
Clear this morning and into the early afternoon under high pressure. The surface high will slide offshore this afternoon leading to a period of onshore flow. Along the coast, a shallow mid level cloud deck may develop as the low level moisture increases and spreads inland. Temperatures will easily reach the upper 60s with a few lower 70s possible over northeastern SC. As moisture increases late tomorrow afternoon and through the early evening, a few sprinkles are possible along the immediate coast. Probability of Precipitation currently capped at 20% given the shallow cloud layer and extremely dry air aloft.

Patchy fog is possible tomorrow evening as dew points continue to rise, winds become mostly calm, and skies remain clear for a brief period. This will be a small window ahead of showers associated with the front. Clouds and shower chances increase overnight from west to east. Onshore flow and increasing cloud cover will maintain temperatures in the low 50s inland to mid and upper 50s along the coast.

Short Term - Wednesday Through Friday

Forecast confidence is moderate to high this period. Wednesday will be a transition day as a warm front lifts north through the area early ahead of an approaching cold front. A pre-frontal band of deep moisture will move through the area Wednesday with showers and possibly a few weak thunderstorms. Most of the rain should occur the first part of the day before drier air moves in aloft ending the risk for heavier rainfall, although a few light showers could still occur given lingering low-level moisture. Gusty winds to near 30 mph are also likely given the strong gradient flow/low-level jet. The potent cold front should then push offshore Wednesday evening with drier and much colder high pressure returning thereafter with temps falling from above normal levels to start the period to below normal levels by the end of the period. In fact, still likely to see a freeze inland Thursday night.

Long Term - Friday Night Through Monday
Forecast confidence is low to moderate through Saturday, then low through Monday. Surface high pressure will shift offshore Friday night allowing more of a southerly return flow to develop Saturday ahead of a cold front which could drop into the area Saturday night. The frontal placement and exact forecast details are a bit uncertain into early next week but conditions should be a bit more unsettled. Temperatures should remain above normal through the period.

Through Tonight
NE winds this morning will shift gradually throughout the day, becoming SE at 10-15 knots this afternoon. As high pressure moves offshore and a cold front approaches the area from the west, the local pressure gradient will tighten this evening. A rapid deterioration of marine conditions is expected between 00Z and 12Z Wednesday. SE winds become southerly by Wednesday morning, increasing to 15-20 knots around sunrise. Seas around 2 feet today will increase overnight to around 2-4 feet by Wednesday morning.

Wednesday through Saturday...Conditions will go downhill Wednesday and especially Wednesday night into early Thursday as a potent cold front moves through the area. Could need a Small Craft Advisory for the local waters later Wednesday into early Thursday, mainly due to gusts possibly up to 30 kt. More tranquil conditions are then expected later this week as high pressure settles over the region.
