Near term (today and tomorrow morning)
With the heaviest storms passing through last night, showers will
continue to push off to the west with skies clearing later this
afternoon. The moist southerly flow that we've been experiencing
will be replaced with cold dry air pressing in from the west later
tonight, leading to clear skies and low overnight temperatures
with a potential for patchy overnight frost formation in southern
georgia. MAX temperatures for the day will range between the mid
50s and low 70s, with the highest temperatures occuring in the
southern part of the region and along the coast. Overnight low
temperatures will drop down into the 30s and 40s.

Much cooler and drier air today through the weekend...

Short term Friday through Sunday ...

sunny skies for Friday, despite sunshine, temperatures will trend
well below normal with highs in the upper 50s SE ga and lower 60s ne
fl. Saturday morning readings will dip into the upper 30s SE ga and mainly 40s
for much of NE fl. Temperatures will start to recover somewhat on
Saturday (highs mid upper 60s SE ga and north of i-10 and lower 70s south of
i-10 as the flow becomes more north northeast as high pressure
dominates into the southeast u.S. Over the weekend. With the high
pressure moving in, clear skies, cooler temps and lower humidities
can be expected through Sunday as highs modify mostly into the 70s
with some upper 60s over NW part of the cwa. By late Sunday, a
backdoor front will move near the georgia coast then move southward
into nassau and duval counties with some showers possible over the adjacent
atlantic.

Long term Sunday night through Wednesday ...

a weak cold front will push south across the region Sunday night,
with a few coastal showers possible. High pressure will build to the
north northwest for the first half of the week. A few of these showers
will develop offshore but a few may push onshore near the coast,
but otherwise it will remain mostly dry into early-mid next week with
near seasonal temperatures.

Aviation
Ifr conditions will persist throughout the early day and then
ceilings will begin to lift later in the afternoon. Winds today
will be predominantly out of the northwest reaching upwards of
10-15 knots.

Marine
An area of low pressure is moving northeast across area waters
this morning and then up the east coast throughout the day.

Hazardous marine conditions will be in effect for small craft
today. High pressure will build from the west today and then to
the northwest into Friday. Broad high pressure will be north of
the region over the weekend. After a weak cold frontal passage
Sunday night, high pressure will build to the northwest for the
first half of next week.

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.
