SYNOPSIS
A warm front will lift up through the region tonight, followed by a cold front passing through later Sunday afternoon and Sunday night. This will maintain unsettled weather across the region through Sunday. High pressure will then prevail through much of next week.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
Rest of Today: Little change is expected in the pattern aloft; SW flow will continue to prevail. At the surface the region will remain well within the warm sector of a low pressure system positioned to the west. Rain has overspread the panhandle of FL and areas to the south of the forecast area, with only some light showers impacting the far southern zones. Models have continued to back off on POPs this afternoon as the ongoing showers and convection to the south are essentially robing the local area of moisture. Light showers should continue to work northeastward into this evening, overspreading the forecast area. Rainfall totals are not forecast to be impressive, generally less than 0.5 inches.
Tonight: Precipitation chances will slowly wane through the overnight hours as a cold front approaches from the west, with only 20-30% POPs by daybreak. The main concern for the overnight period is the possibility of fog/low stratus. The better chances for dense fog are right along the coastline where marine fog could occasionally push onshore. Overnight lows are only forecast to dip into the low to mid 60s.
SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/
Larger scale troughiness will be in place across central NOAM to start the short term, bounded by ridging along either coast, and a couple of stout short-waves pinwheeling around the trough across the Midwest and Ohio River Valley. At the surface, low pressure in the Gulf today will be ejecting quickly northeastward through the mid Atlantic and into New England on Sunday, ahead of the larger scale trough. Strong southwesterly flow ahead of the low will drive an unseasonal warm and moist airmass into the region late tonight through Sunday, with PWAT values nearing 2 inches which, if verified, would be a daily max for Dec 3 per SPC sounding climatology.
Surface cold front will follow, pressing through the region later Sunday and Sunday night with cooler and drier air spreading back into the region to start the work week.
Precip chances remain the primary forecast challenge through Sunday night.
Sunday/Sunday night: As mentioned, a very pronounced and moist warm sector will be in place on Sunday pushing temperatures into the mid to upper 70s along with a touch of mugginess. Main question revolves around precip chances. Once the warm sector arrives, isentropic ascent will weaken considerably on Sunday. But given the very strong upper axis to our northwest, there will be some upper jet forcing support across the region along with modest low level convergence and a degree of instability (a few to several hundred J/Kg of MUCAPE) ahead of the approaching boundary. Plan is to maintain chancy pops throughout the day along with a mention of thunder.
Precip chances diminish and move off the coast Sunday evening.
Rest of the short term: Another strong short-wave will be swinging across the Ohio Valley to off the mid Atlantic coast on Monday, although strongest forcing and better moisture remains well to our north. Thus, keeping the forecast dry. Meanwhile, progressively cooler temperatures are anticipated through the first half of the week. Highs in the middle 60s to around 70 on Monday and down into the lower 60s on Tuesday. Lows in the upper 30s to middle 40s both nights.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Last in the series of short-wave impulses is expected to dive down through the mid Atlantic and southeast CONUS midweek followed by short-wave ridging building through the region for the balance of the long term forecast. Once again, bulk of moisture and forcing remains well to our north on Wednesday and we will keep the forecast dry at this juncture. But with the trough, a couple day stretch of cool temperatures is anticipated with highs mainly in the 50s (well below normal) and chilly overnight temperatures through Thursday morning. Warmer air presses back into the region Friday and into next weekend.
AVIATION /20Z SATURDAY THROUGH THURSDAY/
KCHS/KJZI: Conditions to start the 18Z TAF period will be VFR, however moments of MVFR cig/vis are expected at KJZI and are reflected in a TEMPO group. Light rainfall is expected to move in from the southwest later this afternoon, impacting both terminals. In addition to the rainfall, low cigs are expected to move in overnight with fog/low stratus.
KSAV: MVFR conditions will start off the 18Z TAF period as well as some light rain showers likely ongoing, or will be ongoing soon. Rain showers will continue to work their way into the area through the afternoon. Additionally, low cigs are expected to move in later tonight with fog/low stratus.
Extended Aviation Outlook: Flight restrictions in low clouds and showers will likely persist through Sunday afternoon into Sunday evening, before conditions trend back to VFR later Sunday night and into Monday. Then, overall VFR conditions will prevail through the first half of next week.
MARINE
Tonight: Late tonight winds should turn more southwesterly and begin to increase more into the 10-15 knot range. Seas are forecast to average 2-4 feet.
Fog: Patchy fog seems to be holding on across multiple locations, with local webcams showing patchy fog in the Charleston Harbor and as far south as Tybee Island. Mention of patchy fog has been extended in the forecast for several more hours. It remains unclear if this fog will persist into the overnight, and thus contributing to the fog/low stratus expected overnight. Either way, fog/low stratus is forecast late tonight and into tomorrow morning across the local marine waters as well as the Charleston Harbor. Any sea fog that develops tonight has the potential to linger around until Sunday.
Sunday through Thursday: Southwest winds will persist through Sunday ahead of a cold front and there may be a few gusts into the lower 20 knot range on Sunday across the Charleston nearshore areas, although conditions should remain below Small Craft Advisory criteria. Winds will turn westerly following fropa Sunday night and increase later Monday into Monday night. Another brief period of gusts near 25 knots will be possible mainly across the Charleston county waters and outer Georgia waters during that time...but it looks marginal at this point. A better chance for Small Craft Advisories will occur Tuesday night through Wednesday night behind another cold front.
Conditions will improve for Thursday as high pressure shifts overhead.
