Synopsis
High pressure will maintain dry and cool conditions through the weekend. A coastal low will bring unsettled weather to the area early next week, with an extended period of below normal daytime temps due to high pressure wedge. A second system could bring another round of unsettled weather late week.

Near Term - Through Tonight
The atm column between the surface and 550 mb will remain quite dry thruout this period. Above 550mb, will see pockets of moisture move across the area in the form of thin/opaque cirrus in the 20k to 30k foot level. Overall looking at mostly sunny Saturday and mostly clear Sat night. Stratocu over the adjacent offshore waters at this point should remain over the ATL Waters, possibly reaching the coastal waters at the end of this period as low level NNE-NE flow veers slightly to the ENE especially across the ILM SC Coastal CWA. Some decent Cold Air Advection has worked its way across the FA the past 24 hrs and should allow highs today to only reach the mid to upper 60s. Tonigheights lows similar to Fri night with winds staying active at the surface and within the lower levels to negate any decent rad cooling possibilities.

Short Term - Sunday Through Monday Night
Sunday will be dry and seasonable with high pressure beginning to ridge down from the north. Highs in upper 60s Sunday afternoon with some high clouds moving across overhead. CAD wedge looks to be in place by Monday morning, with near normal low temps in the upper 40s-low 50s. A coastal low will form off the Southeast coast Monday into Tuesday with the approach of a 500mb shortwave, though guidance continues to struggle with how close to the coast the low will get. Regardless, expect increased rain chances Monday and Monday night due to upper level forcing. Current Quantitative Precipitation Forecast through Monday night is 0.5- 1", with the higher amounts to the south. However, ensemble guidance shows a wide range of rainfall for the area from a few hundredths to a few inches so confidence is quite low at this time. Clouds, rain, and CAD will keep high temps Monday around 60F, with near normal lows again Monday night around 50F.

Long Term - Tuesday Through Friday
Below normal daytime temps continue through the long term period, with near normal overnight temps, with CAD in place through mid- week. A second, stronger upper level trough is forecasted to approach the Carolinas late week, though strength and position of the trough remains uncertain. As a result, chance probability of precipitation remain in the forecast for most of the long term period, with Tuesday night into Wednesday currently the driest part of the week. Afternoon wind gusts will be a bit breezy, with gusts 20+ mph most days, due to tightened pressure gradient between high pressure and storm systems.

Marine
Through Saturday...As ridging across the Carolinas from the Great Lakes than SE Canada becomes entrenched across the area, look for NE winds to steadily increase across the local waters to 15 to occasionally 20 kt during this period. By the end of this period, winds and resulting seas will approach SCA (Small Craft Advisory) thresholds, mainly south of Murrells Inlet. Seas will also be steadily increasing in heigheights during this period, 1 to 3 ft this morning, building to 3 to 5 ft by the end of this period. NE windwaves at 6 seconds or less periods will dominate the seas spectrum.

Sunday through Wednesday...With high pressure ridging down from the north inland, northeast winds and seas will be increasing during the day Sunday. Current forecast has SCA (Small Craft Advisory) conditions developing over northeast SC coastal waters by Sunday evening, extending to southeast NC waters by Monday morning. Hazardous marine conditions will likely persist through at least mid-week. A coastal low looks to develop off of the Southeast coast Monday before moving northeastward, though how close it gets to the coast remains uncertain. Regardless, the tightened pressure gradient between the inland high pressure wedge and the coastal low will produce the strongest winds and seas Monday through Tuesday night, with gale- force gusts possible late Monday.
