Area Forecast Discussion National Weather Service Charleston SC 104 AM EST Wed Feb 19 2025

SYNOPSIS
High pressure will build into the area today. A coastal low will track northeastwards off the Georgia/South Carolina coast on Wednesday, with high pressure returning at the end of the week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
The forecast update will align hourly temperatures and sky to recent observations. The current forecast remains generally on track.

A zonal flow will prevail aloft, while upstream a fast moving short wave near the lower Mississippi Valley early on approaches the immediate vicinity late. At the surface, a trough will be situated out near the Gulf Stream, while high pressure relaxes across inland sections. Moisture will increase ahead of the short wave, mainly in the mid and upper levels, and this will allow for an increase in cloud cover. That along with just enough mixing will allow for a warmer night than last night.
Based on recent trends through we did make some minor tweaks to both the hourly temperatures and the overall lows. We have upper 30s and lower 40s well inland, with mid and upper 40s closer to the ocean. While there some forcing due to the approaching short wave, and the proximity to the offshore trough, it looks like the majority of any rains ill hold off until after 6 AM. The exception would be south of I-16 in Georgia, and maybe coastal Charleston close to daybreak.

SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY NIGHT/
Wednesday: Aloft, the flow remains zonal initially until h5 vort energy begins to ripple across the local area mid-late morning. The energy will help promote a coastal low to develop along an inverted trough just off the coast, especially as a h25 jet core becomes favorably positioned across the Southeast. Light rains/showers are expected to develop by mid-late morning hours across southern areas, eventually spreading across Southeast Georgia into Southeast South Carolina by the afternoon. Moisture amounts are modest with low pressure passing south of the region across the Gulf and a northerly wind occurring along the western edge of the coastal low taking shape across the western Atlantic. Temps will remain below normal for the day, peaking in the mid 50s along the coastal corridor and only into the upper 40s inland.

There are some concerns in the forecast heading into Wednesday night with a northerly wind anticipated to hold on through much of the night and drive colder sfc temps into northern areas late evening and after midnight. The key will be how long moisture/light precip holds across the local area heading into overnight hours as latest model soundings and increasing HRRR probabilities indicate a non- zero potential for light freezing rain (trace to 0.01 inch), mainly along and north of a line drawn from Jamestown, SC to Moncks Corner, SC to Reevesville, SC where sfc temps dip to around 30 degrees for a few hours before precip shifts offshore late night. At this point, confidence is low in ice accumulations given some uncertainty in overall precip chances after midnight and especially given soil temps are generally around 50 degrees and likely to limit ice accumulation on the ground. However, there is at least some risk of light freezing rain on elevated surfaces, such as bridges and overpasses and perhaps on trees across northern Berkeley County.
Should winds become light overnight, there is also a non-zero risk of black ice developing prior to daybreak, but again warmer soil temps should limit this overall concern. Elsewhere, including the Charleston metro area, precip is expected to remain in the form of rain/showers.

Thursday and Friday: Colder air arrives late week as the region becomes positioned along the base of a mid-upper lvl trough while dry sfc high pressure is reinforced across the Southeast. Although precip-free conditions are expected, Thursday night/early Friday temps will become chilly (dipping into the low-mid 20s). The combination of these temps and a light northwesterly wind should result in wind chill values in the upper teens across many areas, and likely result in the need for a Cold Weather Advisory prior to daybreak Friday. Despite full days of sunshine, afternoon highs will struggle to reach the mid-upper 40s north to around 50 south, some 15-20 degrees below normal.

LONG TERM /SATURDAY THROUGH TUESDAY/
Saturday will see the aforementioned surface high pressure slide onto the Atlantic, with warmer southerly winds already bringing the region back up into the 50s and lower 60s. Deterministic guidance begins to diverge on the timing of the exiting surface high which propagates through the mid-levels, with ensemble clustering showing the main factor being the strength of the trough along the east coast. At this time, conditions look to remain dry this weekend with high pressure continuing across the region while weak sfc low pressure attempts to develop offshore. Otherwise, the main story is the return of warmer temps in the 60s and 70s to start off next week.

AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
6Z TAFs: Sfc high pressure will ridge across the terminals through the TAF period. An area of low pressure will develop off the GA/SC coast today, tracking to the northeast. This pattern will result in a strengthen area of Cold Air Damming across the region today through this evening. Northeast winds with lowering VFR ceilings will occur across the terminals through daybreak this morning. A large area of rain is forecast to lift north this morning, reaching KSAV by 14Z and KCHS and KJZI by 16Z. Forecast soundings and MOS indicates that ceilings would likely drop to IFR 2-3 hours after the arrival of the rain. Lingering CAD and cooling temperatures tonight will likely result in the llvl inversion to lower tonight. Cloud bases are forecast to drop below 500 ft at KSAV this evening.

Extended Aviation Outlook: TEMPO flight restrictions are possible at CHS/JZI/SAV terminals Wednesday night with passing rain/showers and low clouds associated with a coastal low passing just offshore. VFR conditions are then expected at the terminals through late week.

MARINE
Rest of tonight: An inverted trough will prevail east of the local waters, while high pressure inland weakens. Further upstream will be the development of low pressure along the southern Louisiana coast. There remains enough pinching early tonight locally to generate NE winds as high as 15 or 20 kt, with some higher gusts. Late tonight the gradient does ease off a bit, and winds drop about off around 5 kt. Seas will average 2-4 feet, highest on the Charleston County waters and the outer georgia waters early on.

Wednesday through Sunday: Latest guidance suggests a coastal low developing just off the Southeast Coast Wednesday as h5 shortwave energy passes over an inverted trough axis nearby. The pressure gradient will strengthen in response to the changing conditions, potentially leading to marginal Small Craft Advisory level conditions (~25 kt wind gusts) across northern SC waters off the Charleston County and outer Georgia waters mid-late Wednesday afternoon/evening. High pressure should then become reinforced across local waters Thursday, building seas upwards to 3-5 ft across most nearshore waters and 4-6 ft across northern SC waters off the Charleston County coast as well as across outer Georgia waters.
Additional Small Craft Advisories could be needed Thursday afternoon and night. High pressure will then prevail this weekend with winds/seas expected to remain below Small Craft Advisory levels.
