Near term [through tonight]
A cold airmass will settle over the region tonight in the wake of
this morning's frontal passage. Guidance is in good agreement that
lows will drop into the mid 30s tonight. A few normally colder
location could briefly approach freezing. With the center of the
high progged to be a little to the north, the boundary layer may not
fully decouple, which will limit the potential for widespread frost.

However, patchy frost is expected in sheltered and normally colder
locations.

Short term [Monday through Tuesday night]
In the upper levels a trough will move into the central u.S.

Including the southeast by Tuesday morning. At the surface high
pressure will be over the southeast until Tuesday morning, when a
low begins to form in the gulf. As a gulf low develops pops will
increase by Tuesday morning. The best chance for rain will be near
the coast and in big bend florida with pops in the 50 to 70 percent
range. Elsewhere pops will be in the 20 to 40 percent range on
Tuesday and Tuesday night. Highs will be in the 60s on Monday and in
the upper 60s, lower 70s on Tuesday. Lows will be in the 40s and
lower 50s.

Long term [Wednesday through Sunday]
In the upper levels a trough will be over the southeast throughout
this forecast period. At the surface high pressure will be over
much of the southeast. However a gulf low is expected to develop
nearby and move through central florida. Pops will be elevated
through Thursday night, mainly for big bend florida and south
central georgia (30 to 50 percent pops predicted). Elsewhere pops
will be lower around 20 percent. Highs will be in the 60s. Lows
will be in the 40s.

Winds will diminish this afternoon withVFR conditions prevailing
through Monday afternoon.

easterly tomorrow morning. Strong winds will be possible again

weather conditions are expected for the next several days.

Hydrology
Rain chances are increasing this week as a low is expected to
develop in the gulf. 2 to 2.5 inches of rainfall is predicted near
the coast. 1 to 1.5 inch is expected farther inland. River flooding
is not expected since river levels are still low.

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.
