Dense fog advisory in effect this morning...

Near term (today and tomorrow morning)
Widespread advection fog has spread out over the forecast area
overnight, which will begin to lift with the sunrise and should be
cleared out mid-morning today. Over the course of the day the
prevailing flow will shift to out of the west, bringing in drier
air and reducing precipitation chances. High temperatures for the
day will be in the mid to low 70s. Overnight low temperatures
dropping into the 50s and low 60s, with the higher temperatures
occuring near the shoreline.

Short term Tuesday-Wednesday
Tuesday... Weak mid upper level energy moisture and surface cool
frontal boundary will cross the region from west to east with
decreasing clouds in the afternoon and low chances (less than 20%)
for any measurable precipitation. MAX temps continue above normal
in the lower to middle 70s.

Tuesday night... Clearing skies and cooler temps are expected
behind the cool frontal boundary with lows falling into the 40s
for SE ga inland NE fl, with some lingering lower middle 50s along
the NE fl coastal areas.

Wednesday... High pressure will build north of the region with
mostly sunny skies and more seasonable cooler MAX temps in the
60s lower 70s and for Wednesday night lows 40s inland and 50s
coast as the surface winds turn northeast overnight.

Long term Thursday-Sunday
Thursday Friday... Strong high pressure will build into the
carolinas and breezy NE flow will develop along the coastal areas
with increasing clouds expected on Thursday with scattered to
numerous showers expected Thu night that will continue into
Friday. Seasonable temps are expected with highs in the 60s lower
70s and lows in the 40s 50s. Enough energy aloft and instability
at the surface to trigger an isolated thunderstorm over the atlc
coastal waters or along the NE fl coastline.

Saturday Sunday... High pressure builds into the western atlc and
expect steering flow to become more southerly as weak mid upper
level shortwave energy pushes in from the west aloft and expect
widely scattered showers to continue, while temps will continue to
warm to above normal levels with highs in the 70s and lows in the
50s lower 60s.

Aviation
Dense widespread fog over the forecast region will have airfield
sites in lifr conditions this morning. Fog is expected to lift
after sunrise and conditions will start to improve at around
1300z. Weather will improve toVFR conditions by mid-morning, with
mild northerly winds around 5-7 knots.

Marine
A coastal trough over the local waters will move farther offshore
Monday in advance of a weakening surface cold front. The cold front
will settle south of the area late Tuesday as high pressure builds
northwest of the region Wednesday. Strengthening onshore winds
develop Thursday as high pressure builds over the carolinas and low
pressure develops across the gulf of mexico. Advisory conditions
possible Thursday night and Friday.

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.
