Short term (today - Friday)
Generally zonal flow will hold aloft of florida through the
rest of the week, while a weak shortwave crossing the
southeastern states Friday stays north of florida. At the
surface, weak high pressure over northern florida will
gradually settle south into the florida peninsula tonight
and Friday, with quiet and sunny conditions continuing.

After a cool start to the morning today with some frost
possible mainly over the nature coast, sunny skies will lead
to moderating temperatures through the rest of the week.

Generally, highs are expected to range from the upper 60s
to mid 70s today, then low 70s to around 80 on Friday. Low
temperatures tonight will still be cool, but not as extreme
as the previous couple of days, generally bottoming out in
the 40s to mid 50s.

Long term (Friday night - Wednesday)
Zonal flow aloft at the end of the week will give way as a
strong shortwave trough digs into the southeastern conus
and gulf of mexico during the weekend. At the surface, this
pattern will support a strong area of low pressure lifting
northeast from the lower mississippi river valley through
the mid-atlantic coast, dragging a cold front through the
gulf of mexico Saturday, and the florida peninsula Saturday
night.

Southerly winds ahead of this front will lead to warmer than
normal conditions Saturday afternoon, with building
moisture. Showers and thunderstorms will develop in this
warm and moist prefrontal environment, with scattered to
numerous coverage expected across the area Saturday night
and Sunday, with the highest chances farthest to the north.

Strong cold air advection behind the front will lead to
temperatures barely increasing from the morning lows on
Sunday, then dropping rapidly Sunday night. Low
temperatures will approach freezing over the nature coast
Monday morning, while falling into the upper 30s and 40s
farther south. As high pressure builds into the area Monday
then pushes east into the atlantic on Tuesday, cool
temperatures will hold across the area Monday and Monday
night, then will start to moderate back to near normal on
Tuesday.

The next cold front will arrive on Wednesday, with another
round of showers or storms possible starting late Tuesday.

Aviation
Vfr conditions are expected to hold through the next 24
hours.

Marine
High pressure over the northeastern gulf of mexico will
gradually settle south into the waters through Saturday,
with light winds and slight seas continuing. The pressure
gradient will begin to increase ahead of an approaching
front late Saturday, and will continue to increase Saturday
night and Sunday as the front pushes southeast through the
waters. A period of advisory level winds and seas are
expected Saturday night through Monday morning, subsiding
early next week as high pressure builds back in.

Fire weather
A few hours of critically low humidity will be possible over
the nature coast this afternoon, and from around interstate
4 north on Friday afternoon. However, light wind speeds will
prevent red flag conditions from developing.

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.
