SYNOPSIS
High pressure will build over the area tonight and prevail into Thursday. A storm system could impact the area Friday and Saturday, before high pressure returns early next week.
NEAR TERM /THROUGH TODAY/
As of 145 AM, water vapor satellite product indicated that the mid-level shortwave was rippling over the forecast area. Based on satellite trends, the disturbance should shift off the Carolina coast between 4-5 AM. The thin high clouds ahead of the trough will likely push east of forecast area by 3 AM. The rest of the night should feature clear and dry conditions, gusty NW winds are forecast to begin to decrease in the wake of the mid- level disturbance. A Lake Wind Advisory will remain in effect for the rest of tonight.
Temperature-wise: Strong cold advection drives the 850 mb temps down into the -2C to -4C range by morning. This is far below normal, which should be around 8.5C to 8.7C. Along with diminishing winds and clearing skies, lows will drop through the 30s for all areas away from the coast with the coldest readings well inland. Associated wind chills will be as low as in the 20s far inland late. Persistent winds and dry incoming air mass will limit frost development to no more than maybe a little patchy coverage late near the US-301 corridor, but only if RH levels are high enough.
SHORT TERM /TONIGHT THROUGH THURSDAY/
Aloft, a large trough will pivot offshore Tuesday, shifting further away from the region while a zonal flow takes place across the Southeast United States through mid-week. At the sfc, high pressure across the South-central United States will extend east across Gulf Coast states and Carolinas Tuesday into Wednesday, before a cold front arrives from the north/northwest by early Thursday.
Conditions will remain dry locally through the middle of the week while a west-northwest downslope wind prevails along the eastern edge of the high centered to our west, even as the cold front pushes into the local area by early Thursday. Despite ample sfc heating under clear skies, temps will struggle to warm significantly on Tuesday while weak cold air advection wanes across the region. In general, high temps should only peak in the upper 50s to lower 60s (warmest across southeast Georgia). Although temps are cooler during peak heating, dry air should lead to afternoon RH values between 20- 25% away from the coast Tuesday afternoon. Sfc winds are expected to remain below 10 mph though, so fire wx concerns should be limited.
Sfc winds should slowly turn southwest Tuesday night into Wednesday, offsetting some radiational cooling at night and resulting in airmass modification on Wednesday ahead of an arriving cold front.
In general, Tuesday night lows should dip into the upper 30s/lower 40s inland to mid-upper 40s near the coast. On Wednesday, high temps should peak in the lower 70s with sunny conditions in place.
Guidance indicates a dry cold front pushing across the region Wednesday night, likely becoming positioned along or just south of the local area by daybreak Thursday. Despite northerly winds post fropa, sfc temps should peak in the lower 70s under partly sunny skies in advance of a low pressure system developing and shifting eastward across the northern Gulf of Mexico heading into late week.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
The weather becomes more active as we head into late week, although still some forecast details to hash out. An upper wave is expected to pass across the Southeast United States early Friday through early Saturday, forcing an area of low pressure across the northeast Gulf to possibly strengthen while tracking over/near the Georgia and South Carolina coasts. PWATs should increase to around 1.25 inches as the system nears, and with strong isentropic ascent and a lingering front across the area, should promote showers to develop locally Thursday night into Friday morning. Scattered to numerous showers are now forecast to occur for most areas Friday and Friday evening, before precip activity trends offshore with the sfc low pulling away Saturday. Some guidance suggests some modest instability developing near the coast and offshore as the low tracks near the region, so a few embedded thunderstorms are possible along the immediate coast.
The aforementioned low should continue to depart the region late weekend as high pressure builds inland. Aside from some lingering showers Saturday morning into early afternoon, precip chances should become confined to the coastal waters by Saturday evening. Dry conditions should then prevail Sunday with high pressure in place.
AVIATION /05Z TUESDAY THROUGH SATURDAY/
6Z TAFs: Terminals will remain VFR through the TAF period.
Northwest winds are forecast to continue to gusts between 20-25 kts as high pressure builds in from the west early this morning.
The gusts are timed to end around daybreak today. This afternoon, the sfc ridge is forecast to shift offshore as a broad trough develops in the lee of the Appalachians. Winds are forecast to shift from the southwest between 5-10 kt.
Extended Aviation Outlook: VFR conditions are expected Tuesday night through Thursday. Flight restrictions are possible at KCHS/KJZI/KSAV terminals Thursday night into Friday as showers/low clouds develop with a passing low pressure system.
MARINE
Tonight: A strong 1027 mb high centered near the Arklatex will expand east and stretch over the coastal waters. A tight gradient, with as much as a 3 or 4 mb spread, plus constant isallobaric pressure climbs will exist. Those conditions along with significant cold air advection will allow for good mixing of the 35 or 40 kt geostrophic winds. As a result we have Gale Warnings in effect for all Atlantic waters, with a high end Small Craft Advisory in Charleston Harbor. Seas will be limited close to shore due to the offshore fetch with NW winds. But as one navigates further into the Atlantic, seas will be as high as 5 feet near 20 nm out, and up to 8 feet beyond 40 or 50 nm out.
Tuesday through Saturday: Marine conditions will improve on Tuesday, although there will be another brief wind surge Tuesday night with gusts to near advisory criteria, especially over the Charleston County waters. A somewhat enhanced pressure gradient could support elevated winds through late week, but conditions should remain just below Small Craft Advisory levels through Thursday. An area of low pressure is then expected to pass near/off the Southeast Coast Friday into Saturday, likely contributing to deteriorating marine conditions across local waters this weekend. Small Craft Advisories should be needed across most waters, but the track/strength of the low pressure system will play a large role in overall impacts along the Southeast Coast.
