Synopsis
High pressure and unseasonably hot conditions will dominate
into late next week.

Near term until 6 am Saturday morning
Early Friday evening: ongoing forecasts remained on track and
required only a few hourly adjustments into the evening. After
a hot early evening, deep-layered ridging will provide a mainly
clear and warm night. By daybreak, low temperatures will range
from the upper 60s lower 70s inland to the lower middle 70s
near the coast.

Short term 6 am Saturday morning through Monday
A deep layer ridge is expected to be locked in over the southeast
u.S., centered near the northern gulf coast through the period. With
rising mid and upper level heights and west-southwest low level
flow, high temperatures are expected to approach or exceed record
values. Overall, models generally showing highs in the mid to upper
90s most areas away from the immediate coast. Even could see
temperatures around 100, especially by Sunday and Monday. Late
afternoon sea breezes are expected to be weak and not penetrate very
far inland each day, which will hold relatively cooler afternoon
highs close to the immediate coast. Models indicate afternoon
dewpoint temperatures will mix down a bit each day, possibly down
around 60 well west of i-95, and mid to upper 60s close to the
coast. If this pans out, afternoon MAX heat indices should hold in
the 100 to 103 range. There could be a few spots that get closer to
105, which is minimal heat advisory levels.

No significant rain chances expected through the period. Kept
low slight chance pops on Saturday in the presence of a weak
backdoor front over the northern charleston tri-county region, but
confidence not very high. GFS showing another weak backdoor type
front Sunday night and Monday, but with a lack of deep layer
moisture and forcing, have kept out mention of rain chances for
now.

Long term Monday night through Friday
The mid-level ridge will remain in place while surface high pressure
persists. Temperatures may trend downward a few degrees each day.

However, they are still forecasted to remain well above normal
throughout the long term. Additionally, no rainfall is in the
forecast. Heat advisories, poor air quality, and dry fuels that
could increase the risk of wildfires are all concerns. But the
details will need to be better defined as this time period gets
closer.

Aviation 00z Saturday through Wednesday
Vfr.

Extended aviation outlook:VFR.

Marine
A southerly sea breeze of 10-15 knots early will give way to
southwest winds of 5-15 kts. Wave heights will average 1-3 ft.

No highlights expected through the remainder of this forecast
period. The axis of high pressure is expected to remain just
south of the waters, keeping west- southwest winds of mainly 15
knots or less and seas 3 feet or less through mid week. Winds
could increase more toward 15 knots Sunday night and the first
part of Monday over sc waters as a weak front potentially stalls
and then dissipates over the northern waters.

Climate
A significant, prolonged heat wave will challenge or break many
of these records:
all time record highs for may:
kchs: 99 set may 21, 1938.

Ksav: 101 set may 30, 1898 and may 31, 1945.

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.
