SYNOPSIS
Atlantic high pressure will remain across the Southeast through much of next week.
NEAR TERM /THROUGH TONIGHT/
Visibility is steadily improving across the interior as mixing comences. The Dense Fog Advisory has been be cancelled for all but the far interior where conditions will remain near advisory levels for another hour or so.
Today: The mid level ridging of recent days will shift off the coast of the Southeast, while Atlantic high pressure is the main feature at the surface. The synoptic flow is southeasterly through the day, resulting in a sea breeze dominant regime.
After fog dissipates, scattered to broken cumulus will prevail, while varying amounts of cirrus clouds pass through. There will certainly be sufficient insolation, and temperatures will be very similar to yesterday. We didn't go quite as warm as the 1000-850 mb thickness progs, but with a blend of the MOS and NBM, we arrive at highs in the mid and upper 80s. Coastal sections will be 5-10F cooler.
A subtle level level impulse will approach from the west- southwest late in the day, and this will cause isolated to scattered convection upstream from our Georgia counties to approach. There will be some interaction of this activity with the inland moving sea breeze after 3 or 4 pm, where we show slight chance PoPs close to and west of the US-301 corridor (Allendale to Tattnall County). There is little buoyancy, plus limited MLCAPE and shear, so no strong or severe storm will occur.
Tonight: A better looking short wave trough moves through the Tennessee Valley and northern Gulf coast. This along with any outflow boundaries from prior convection in and near the area, will allow for isolated or scattered showers and a few t-storms to occur. This is mainly far inland sections. There will be at least some form of fog again after midnight given the southeast and south flow in the boundary layer. However, there is likely too much mid and high level clouds from the nearby convection for dense fog to occur. We currently have mention of the "patchy" fog qualifier, and we will monitor for any dense fog potential. Low temperatures will be several degrees above climo.
SHORT TERM /SATURDAY THROUGH MONDAY/
A mid-level ridge axis will push off the Southeast coast Saturday with passing waves of shortwave energy across the region through the short term forecast period. High pressure will remain the primary feature at the surface. Convection should be a bit more active over the weekend and into Monday with the presence of deeper moisture as PWATs increase to 1.5+ inches. Coverage of showers/thunderstorms will be highest in the daytime when instability is maximized, but with some upper forcing in play activity could linger into the overnight period. The greatest chances are focused away from the immediate coast owing to a progressive sea breeze.
High temperatures will generally peak in the low to mid 80s over the weekend, warming into the mid to upper 80s Monday. Overnight lows are only expected to drop to the mid to upper 60s, with locations right along the beaches and Downtown Charleston near 70 degrees.
LONG TERM /MONDAY NIGHT THROUGH THURSDAY/
Atlantic high pressure will persist through the middle of next week.
Chances for showers/thunderstorms are limited Tuesday as weak forcing/remnant shortwave energy passes offshore the Mid Atlantic coast. Beyond Tuesday, rainfall chances are little to none as a ridge rebuilds overhead. This will allow max temperatures to rise into the low/mid 90s by mid next week, possibly approaching record levels by Wednesday/Thursday.
AVIATION /13Z FRIDAY THROUGH TUESDAY/
KCHS/KJZI/KSAV: Other than a little light fog at KSAV through 13, VFR will prevail at all terminals. The potential for fog tonight t is less than recent nights, and would likely occur inland from the terminals anyway.
There are no concerns for SHRA or TSRA at any the terminals with the 12Z TAFs.
Extended Aviation Outlook: Scattered showers and thunderstorms are possible through Monday.
MARINE
Today: High pressure from the Atlantic will be the main feature, and even with sea breeze influences this afternoon, SE winds will be no more than about 10 kt. Seas will be only around 2 feet. Even though it is light, the onshore flow will keep any land based fog off the Atlantic. The exceptions will be Charleston Harbor (especially the northern part of the harbor near the North Charleston Port) and the Port of Savannah, where some of the nearby fog from over the land could drift into those areas early this morning. At this time no Dense Fog Advisory is planned.
Tonight: Weak high pressure continues across the maritime community. Once again the SE winds are no more than about 10 kt, with seas just 2 feet. Maybe some fog could impact Charleston Harbor and the Port of Savannah, as it tries to expand in from nearby land sections.
Saturday through Wednesday: Atlantic high pressure will maintain benign conditions over the local waters. Southerly winds in the morning will back out of the southeast during the afternoon and evening hours nearly each day as the sea breeze develops. Winds will average 10-15 kt with seas 2-3 ft.
