SYNOPSIS. High pressure will build from the west through the weekend and then slide offshore on Monday. A cold front will then cross the area Tuesday, followed by high pressure into late next week. Low pressure should then develop along the coast next weekend.

NEAR TERM /THROUGH TONIGHT/. A potent upper shortwave will shift east of the area late today while dry high pressure at the surface moves in from the west. Low stratus remains prevalent, though with much drier air continuing to move in from the west and strengthening downslope flow, the clouds should fairly quickly erode early this afternoon. Temperatures have risen little so far this morning due to the extensive clouds. A quick rise into the low 60s is expected early to mid afternoon once the clouds clear and downslope flow strengthens. As afternoon sunshine returns, a deepening mixed layer will allow for occasionally breezy conditions.

Lake Winds: Since Lake Moultrie water temps were in the lower 50s, we think gusty west winds will be stronger on western and southern lake shores with sub-advisory conditions over the open lake.

Tonight: High pressure will slowly build from the west and surface winds are expected to gradually decouple overnight. A few of our normally cooler inland spots could dip into the mid 30s late, many areas will dip to around 40 degrees near daybreak on Sunday.

SHORT TERM /SUNDAY THROUGH TUESDAY/. Sunday and Monday: High pressure will slowly build across the area early in the week, eventually becoming centered off the Southeast Coast by early Monday. The changing pattern will favor a warming trend as west winds turn south well ahead of a developing low pressure system tracking across the Central United States. In general, high temps will peak in the mid/upper 60s on Sunday, then mid 70s under gradual mid-lvl ridging and mostly sunny skies on Monday. Overnight lows should range in the mid/upper 40s away from the coast Sunday night, followed by much milder temps in the upper 50s/lower 60s Monday night.

Tuesday: The area will be warm-sectored for much of the day ahead of a cold front expected to sweep through the Southeast United States during the afternoon into evening hours. Despite widespread clouds, temps should approach the mid 70s across most areas before the onset of precip closer to the arriving front. Latest guidance suggests sfc instability to remain rather weak during the period, but sufficient for a few thunderstorms embedded within numerous to widespread showers spreading west to east across the area during the afternoon. Expect the bulk of precip activity to shift offshore during evening hours, especially as winds turn more west post fropa and high pressure builds across inland areas late.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Dry and cooler high pressure will spread across the region Tuesday night through Thursday with high/low temps some 15-20 degrees cooler than earlier in the week. In general, high temps will peak in the mid 50s Wednesday and Thursday while overnight lows dip into the low/mid 30s away from the coast Wednesday night and Thursday night. Guidance then suggests the potential for precip to return across the area next weekend, mainly due to a coastal trough/low developing just off the Southeast Coast. Precip chances should be highest near the land/sea interface Saturday. Temps will be slightly more mild during the weekend as well, peaking in the upper 50s/lower 60s each day. Overnight lows should range in the upper 30s/lower 40s away from the coast.

AVIATION /19Z SATURDAY THROUGH THURSDAY/. VFR conditions will prevail at both terminals. During the afternoon hours expect to see only scattered clouds at best. Gusty west winds will persist until shortly before dusk, with possible gusts up to 25 kt. After dusk, winds will be light and westerly through 18Z Sunday.

Extended Aviation Outlook: VFR conditions will prevail Sunday and Monday at both CHS and SAV terminals. Flight restrictions are possible at both terminals Tuesday due to showers/thunderstorms along a passing cold front. VFR conditions should then prevail at both terminals Wednesday.

MARINE. Following the cold front passage, favorable mixing profiles will result in some 25 kt gusts across all but nearshore GA waters today. Additionally, seas at or above 6 ft expected into tonight over the GA offshore and Charleston nearshore waters.

Sunday through Thursday: Winds/seas will decrease/subside to levels well below Small Craft Advisory criteria Sunday and Monday as high pressure builds across the region, then becomes centered off the Southeast Coast. West winds will turn south heading into Tuesday before a cold front shifts across coastal waters late afternoon into the evening. Southerly flow could also favor some sea fog on Tuesday as low/mid 60 dewpts spread across all coastal waters within the warm sector ahead of the front. Strong cold air advection in wake of the front should then produce a period of Small Craft Advisory level conditions across a portion of the coastal waters Tuesday night into Wednesday. High pressure will then build across the area from the north through Thursday, favoring north/northeast winds around 15-20 kts as the pressure gradient remains somewhat enhanced along the coast. Seas of 6 ft could also persist across offshore Georgia waters during this time, resulting in a Small Craft Advisory late Wednesday into Thursday.

CHS WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None. MARINE . Small Craft Advisory until 6 PM EST this evening for AMZ330. Small Craft Advisory until 9 PM EST this evening for AMZ352.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
