Short term (tonight - Tuesday)
A positively tilted upper level trough over the central
rockies this afternoon will slow down as it moves
southeastward into the southern plains tonight through
Tuesday as it encounters strong upper ridging to its east
with a cut-off low developing over eastern texas through
Wednesday. At the surface an area of low pressure over the
gulf coast along a frontal boundary draped across the
northern gulf coast will move northeast along the boundary
across the deep south tonight, deepening as it moves
northeast up along the mid atlantic coast on Tuesday with a
trailing cold front limping eastward through the panhandle
tonight, and then approaching the northern peninsula on
Tuesday as it becomes parallel to the deep layered southwest
flow aloft.

For tonight ample moisture within the warm sector south of
the northward moving warm front combined with light winds
will support some fog development overnight, especially from
central interior zones north into the nature coast. In
addition to the fog some low rain chances (pops 20 percent)
will remain in the forecast as well, mainly across the
northern nature coast closest to the warm front. It will be
a very mild and muggy night with overnight lows in the upper
60s to lower 70s area-wide.

On Tuesday upper level and surface ridging from the atlantic
and extending west across the south-central peninsula will
remain in control as the aforementioned cold front limps
eastward toward the northern peninsula during the day.

Adequate moisture and instability within the warm sector
should support some scattered showers and isolated storms
under partly to mostly cloudy skies. A south to southwest
wind flow will make for another very warm day with
temperatures again climbing into the mid and upper 80s
during the afternoon with some near record highs again
possible.

Long term (Tuesday night - Monday)
A highly amplified upper pattern has set up over the conus
to start out the long term period. A broad elongated area
of ridging south of bermuda extends southwest over the
bahamas, cuba and into the central caribbean sea. Farther to
the west, a closed upper low over eastern texas sits in the
base of a deepening trough that will sweep through the
southeast u.S. Through the end of the week. The eastern half
of the u.S. Will be under the influence of broad troughing
by Saturday and will continue into next week. This troughing
will lend support to the next weather system moving through
the southeast u.S. Later this week and also help to usher
in some much cooler air through the weekend.

On the surface, high pressure has shifted east of bermuda
while an extensive frontal boundary extends along the
eastern seaboard from an area of low pressure near maine.

The low moves rapidly to the northeast by Wednesday evening
and the frontal boundary becomes oriented more northeast
through southwest and extends over northern florida into the
gulf of mexico. Another area of low pressure develops along
the trailing edge of this front by late Wednesday into
Thursday and will give us our highest chance of rain storms
(50- 70% pops) during that period. The system is expected to
exit the area by late Thursday as high pressure pushes into
the area from the northwest. With this high pressure,
pleasant weather with cooler and drier air can be expected
through the weekend and into next week.

Aviation
Some MVFR ifr CIGS and vsbys from some low clouds and fog
may impact the terminals between 09-13z Tuesday morning,
otherwiseVFR is expected during the next 24 hours.

Southeast to south winds around 10 knots this afternoon will
diminish to 5 knots or less after 02z tonight, then
increase to 6 to 8 knots after 15z on Tuesday.

Marine
A warm front will lift north of the waters later tonight.

High pressure from the atlantic across the south-central
peninsula will support a southeast to southerly wind flow
over the gulf waters tonight as a cold front slowly moves
east toward the western panhandle. During Tuesday through
Wednesday a south to southwest wind flow can be expected
across the waters as the aforementioned cold front moves
toward the northern peninsula. During Thursday developing
low pressure across the northeast gulf will deepen as it
moves northeast up along the eastern seaboard through
Friday. As the low lifts out to the northeast a trailing
cold front will get pulled southeast through the waters late
Thursday night into Friday with winds shifting into the
northwest and north in its wake with cautionary or small
craft conditions likely on Friday with hazardous boating
conditions developing. Lighter winds and seas will return to
the waters on Saturday as surface high pressure builds in
over the gulf in the wake of the front.

Fire weather
Humidity values will remain above critical levels through
the remainder of the week with no fire weather hazards
expected. Some late night and early morning fog will be
possible over inland locations the next few days with some
reduced visibility possible. Drier and cooler air will move
into the region late in the week and into next weekend in
the wake of a cold front with much lower humidity expected.

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.
