Synopsis
Surface high pressure centered over the great lakes region will
extend southward into our area through Monday. High pressure will
weaken a bit as hurricane maria moves northward off the carolina
coast Monday through Thursday. Above normal temperatures will cool
for the end of next week behind a moisture limited cold front.

Near term until 6 pm this evening
Upper level low over the gulf coast area retrograding to the
west. Upper level ridge over the northeast and great lakes
region. A surface ridge over the mid atlantic region extending
south across the carolinas. Some increase in mid and high level
clouds mainly in the east through the day with northeast winds.

Model soundings indicate air mass will be drying out through the
day and mid level temperatures warm. Air mass appears to dry
out during the afternoon. Temperatures similar to yesterday
maybe a degree cooler... Still upper 80s... Near 90 degrees.

Short term 6 pm this evening through Tuesday
An upper level ridge over the northeastern and mid atlantic states
will continue extending into the carolinas through Monday. Air
mass remains dry and capped. Hurricane maria will be moving
north well east of the south carolina coast. Aside from
increased waves and swells along the coast no impacts are
expected from hurricane maria. Models have been consistently
showing above normal temperatures with with afternoon highs in
the upper 80s to lower 90s and overnight lows in the 60s.

Long term Tuesday night through Saturday
Models show a pattern shift taking place for the latter half of next
week. The trough ridge over the west east on Tuesday will transition
to a ridge trough over the west east by Friday.

Surface high pressure extending from the eastern great lakes to the
gulf of mexico through Wednesday will weaken as maria moves
northward off the carolina coast through Thursday. Although the
official track of maria has shifted slightly westward, maria is
forecast to remain offshore with no impacts for midlands and
csra. A moisture limited frontal boundary moving through on
Friday will bring cooler temperatures for next weekend.

Aviation 07z Sunday through Thursday
Vfr conditions to dominate the period... With patchy early
morning fog and stratus possible.

Weak high pressure over the mid atlantic will continue pushing
dry air into the terminals through the period. Potential for fog
and stratus through daybreak are low... However have remained
with mention at fog prone ags. Some potential for fog around
daybreak at other terminals... However potential too low to
mention and will handle with tempo group if needed. Fog which

through the afternoon hours with no convection expected.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
