SYNOPSIS
High pressure will persist through tonight. A slow moving front will bring unsettled weather to our area Friday through early next week. High pressure returns by the middle of next week.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
Tonight: Zonal flow will prevail aloft while at the surface high pressure will hold strong. Winds have already decoupled far inland, while some mid and high level clouds move in from the west in advance of a subtle short wave that approaches the forecast zones late.The main challenge will be in regards to how much radiational cooling occurs prior to when these clouds get more opaque. Thus we haven't made any adjustments to min temperatures, as we are still showing mainly 60-65F degrees inland, mid to upper 60s in downtown Savannah, the Charleston- North Charleston metro, and on the barrier islands.
Some of the guidance hints at showers getting close to our far northwest tier closer to daybreak, and this possibility will need to be closely monitored through the night.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/
Weak high pressure over the western Atlantic will shift east on Friday. Aloft, a weak shortwave will move off the coast in the morning, then relatively zonal flow will persist for the rest of the day into Friday night. The lowest 300 mb will feature 10-20 kt WNW flow through the afternoon. The resulting downslope compression will push highs into the upper 80s to around 90.
This will also produce large scale subsidence, limiting the potential for convection to develop. There will be a weak cold front sagging toward our NW zones late in the afternoon. Despite the subsidence, models show SBCAPE around 1500 J/kg and 30-40 kt bulk shear, so we cannot rule out isolated to scattered showers and tstms, mainly inland. And an isolated severe storm is not out of the realm of possibility.
Saturday will remain quite toasty due to the broad upper ridge and low-level compression along the southern edge of the backdoor front. Highs will be in the upper 80s to lower 90s. A bit more convective coverage is expected due to some late day upper shortwave energy, the weak surface boundary in the vicinity, and higher PWATs.
The upper level pattern changes drastically on Sunday as an upper trough progresses across the eastern United States and the surface front drops farther south. Temps will be considerably cooler on Sunday due to overcast skies and cool advection. Highs across inland SC could only be in the lower 70s, though farther south along the Altamaha River in GA we expect low to mid 80s.
Numerous to widespread showers and thunderstorms are expected, especially late in the day, due to strong synoptic scale forcing and ample low-level moisture.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
Wet weather continues Sunday night as the primary shortwave swings through and a weak low moves up the coast. Some areas could see upwards of half an inch of precipitation (locally heavier). Rain should taper off by Monday morning as cool high pressure builds in.
AVIATION /02Z FRIDAY THROUGH TUESDAY/
VFR conditions will prevail at CHS/JZI/SAV terminals through 00Z Saturday. The risk for any SHRA or TSRA Friday is too minimal to include at this time.
Extended Aviation Outlook: A slow moving front could bring occasional flight restrictions late Saturday through Monday.
MARINE
Tonight: Quiet conditions are forecast across the marine waters as high pressure remains the dominant feature across the region.
Mostly SW winds of 10-15 knots or less are forecast, with seas averaging 2 to 3 ft.
A moderate S/SW flow Friday into Saturday will turn to the NE late Saturday night as a cold front drops through the area.
Sunday through Monday will feature the strongest winds of the period with readings occasionally ranging from 15-20 kt due to a tightening gradient. Slightly weaker NE flow expected Tuesday, then winds turn back to southerly by Wednesday as weak high pressure builds over the western Atlantic.
CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...None.
