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

Near term through tonight
An upper level ridge over the northeastern and mid atlantic states
will continue extending into the carolinas today. Hurricane
maria will be moving north well east of the south carolina
coast. Air mass dry today although considerable high level thin
clouds expected through the day. Temperatures may be slightly
cooler than yesterday due to high clouds with northeast low-
level flow.

Low level mixing, dry air and high clouds will prevent fog
formation. The cirrus layer will also prevent ideal radiational
cooling conditions. Expect temperatures in the mid to upper
60s.

Short term Tuesday through Wednesday
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. Model consensus indicating above
normal temperatures through the period. Afternoon highs in the
upper 80s Tuesday. A little warmer Wednesday due to less clouds
and downslope flow as hurricane maria moves well to the
northeast. Lows 65 to 70.

Long term Wednesday night through Sunday
Models show a pattern shift taking place for the latter half of
the week. The trough ridge over the west east transitioning to
a ridge trough over the west east by Friday.

Surface high pressure extending from the eastern great lakes to the
gulf of mexico will weaken as maria moves northward well off
the carolina coast through Thursday. A moisture limited
frontal boundary moving through on Friday will bring cooler
temperatures for next weekend, generally a couple of degrees
below normal. Moisture over florida associated with upper level
low should remain to the south and east of the area through the
weekend.

Aviation 15z Monday through Friday
Vfr conditions through the period.

Drier air over the region will be reinforced today as high
pressure over new england pushes additional dry air southward.

Expect some cumulus through the afternoon hours and cirrus blow
off from hurricane maria also across the region. Maria will be
moving slowly northward well offshore of the carolinas through
the period keeping northerly winds at the terminals with speeds
around 10 knots from mid morning through the early evening
hours... Then diminishing to 5 knots tonight. With the drier air,
high clouds and light winds tonight fog is not expected.

Extended aviation outlook... No significant impacts to aviation
expected Tuesday through Friday.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
