Synopsis
High pressure will be the dominant weather feature into next
week.

Near term through tonight
Pre-dawn: another tranquil morning over the forecast area as
deep layered ridging prevails. Mainly clear skies with light
to calm winds and temps ranging from the mid upper 60s around
daybreak, except readings at or above 70 degrees adjacent to
the intra-coastal and atlantic waters.

Today: ridging aloft is forecast to narrow a bit between
mid level short wave energy shifting from the plains toward the
great lakes and a weak low just north of the bahamas. The surface
ridge axis has slowly lifted a bit north of 30n and this should
result in more of a southeast synoptic flow later today. The
sea breeze should be even a bit more progressive on it's inland
push. Temps will likely be a couple degrees less than on Sunday
over the coastal corridor. We maintained a forecast with silent
pops over inland zones at mid to late afternoon. Dry air aloft
looks substantial, especially in the 850-500mb layers where
condensation pressure deficits are higher than on Saturday.

While a few spotty showers may pop along the sea breeze (mainly
west of i-95) dry and warm weather will continue to persist
otherwise.

Tonight: the narrow upper ridge will prevail across our entire
forecast area while a weak mid level short wave make it's way
to north ga late. Skies should remain most clear although some
lower stratocumulus could come off the water along the coast
late. Low temps similar to past mornings, not much change to the
forecast.

Short term Monday through Wednesday
Monday and Tuesday: the mid upper lvl ridge will temporarily weaken
with the approach of a h5 shortwave sfc cold front Monday evening
and night. Guidance suggests the front will be in a weakening state,
likely stalling before reaching the area, then shifting back north
on Tuesday. However, a few showers thunderstorms remain possible
over parts of southeast south carolina Monday afternoon evening,
then again Tuesday afternoon evening as h5 shortwave energy moves
across the area during peak diurnal heating. High temps should peak
in the upper 80s to lower 90s away from the coast Monday, then warm
into the lower to middle 90s away from the coast Tuesday. Lows
should range in the upper 60s to around 70 degrees.

Wednesday: sfc high pressure will eventually become centered along
the mid-atlantic and southeast coasts while a mid upper lvl ridge of
high pressure builds aloft. Given the setup, warm and dry conditions
will likely prevail mid week. In general, highs should warm into the
low mid 90s well inland while a more direct onshore wind limits
highs to the mid upper 80s east of the i-95 corridor.

Long term Wednesday night through Saturday
Dry weather should prevail mid to late week as sfc high pressure
extending from the western atlantic becomes centered over the
southeast under a building ridge of high pressure aloft. A warming
trend is anticipated through the week as the ridge aloft becomes
quite strong and centered over the southeast united states. Highs
should generally range in the low mid 90s away from the coast
Wednesday and Thursday with overnight lows in the upper 60s lower
70s. Temps should be even warmer during the weekend as the mid upper
lvl ridge makes a slight shift south, setting up a west-northwest
downslope flow across the region. This includes warmer conditions
along the beaches given the potential for a pinned seabreeze. In
general, afternoon highs should peak in the mid upper 90s away from
the coast and mid upper 80s along near the beaches. The combination
of heat and mixed out moisture could support heat index values
around 100 degrees away from the coast Friday afternoon and Saturday
afternoon. Overnight lows should also be mild, generally in the
low mid 70s each night.

Aviation 07z Sunday through Thursday
Vfr at kchs ksav through 06z Monday.

Extended aviation outlook:VFR conditions are expected at both chs
and sav terminals through the middle of the week.

Marine
A southerly flow will persist through tonight, with near shore
backing to more southeast during the afternoon and evening
hours along ga coast waters. Prior to daybreak Monday morning,
speeds will mainly be 15 kt or less and seas 2-3 ft with 3-4 ft
seas over outer ga waters later tonight.

Monday through Friday: high pressure will remain the dominant
weather feature across the coastal waters through late week,
supporting winds seas that remain below small craft advisory
levels. In general, south southwest winds will prevail through
Tuesday with wind speeds no higher than 15 kts. By Wednesday,
winds should become more south southeast, but remain at or below
10-15 kt as sfc high pressure stretches across the western
atlantic. Seas will range between 1-3 ft into Tuesday, then
build no higher than 1-2 ft Wednesday and Thursday.

Tides coastal flooding
Shallow coastal flooding is possible with the high tide this
evening along parts of the south carolina coast. We continue
mention this chance in the hazardous weather outlook.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
