Update
Dense fog continues across the interior this morning, with sea fog
over the nearshore marine waters. The fog will lift and scatter
out by late this morning. It was drier and cooler across the
region compared to yesterday, but still expect temperatures to
reach near record to record highs this afternoon after the fog and
stratus scatter out. Highs will be in the mid to upper 80s across
the interior, and the upper 70s to lower 80s along the coast. A
small tongue of moisture remained across the southeastern portion
of northeast florida, and isolated to scattered showers are
possible this afternoon into the early evening. Elsewhere, dry
conditions will prevail. A backdoor front will slide southwest
down the coast of georgia this evening, and into southeast georgia
before stalling and lifting back northward. Guidance is
indicating that sea fog over the atlantic waters will move inland
tonight due to the flow shifting to the northeast, with dense fog
possible over coastal areas and along and south of the frontal
boundary before daybreak on Saturday.

Aviation
Fog and low stratus will clear out by this afternoon, withVFR
conditions then prevailing through the day. Guidance is indicating
that sea fog will develop over the atlantic waters tonight and
move inland as as backdoor front moves down the coast.

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.
