Short term (today - Tuesday)
A strong mid level ridge of high pressure holding over the
florida peninsula early this week is causing broad
subsidence, which will keep warm and dry conditions in
place. At the surface, high pressure will continue to ridge
north of florida, setting up light easterly flow. The
gradient flow will remain light enough that a limited west
coast sea breeze should develop, but will remain fairly
close to the west coast. Temperatures will generally run 5-8
degrees above normal, with afternoon highs topping out in
the low 90s in most places away from the immediate coast.

This could lead to a few spots breaking or matching
temperature records for the day. A few isolated showers
could develop in the afternoon, but most areas are expected
to remain rain free.

Little will change for Tuesday, with another day of easterly
winds and near record temperatures. Atmospheric moisture
will be slightly higher, and a few more afternoon showers
or storms will be possible, with rain chances of 10-20
percent across the area.

Long term (Tuesday night - Sunday)
During the middle part of the week, a broad upper level
trough will swing through the great lakes region and
northeastern us, allowing the mid level ridge to slightly
weaken and shift east. At the surface, the sub-tropical
ridge axis north of florida will shift east Wednesday and
Thursday before a backdoor cold front pushes into florida
from the northeast Friday and Saturday. Through all this,
easterly low level winds will continue through the week and
into next weekend, with weak sea breezes developing each
afternoon and staying near the coast.

With the mid level ridge of high pressure still overhead
Wednesday, subsidence will cause warm and rather dry
conditions to continue, with near record temperatures, and
limited rain chances. As the ridge weakens and shifts out,
temperatures will moderate slightly through the rest of the
week, but will still remain above normal through Saturday,
rain chances will also pickup Thursday through Saturday due
partly to increasing moisture along and ahead of the
backdoor front and reduced subsidence aloft.

Models are in good agreement regarding another mid level
trough swinging into the eastern us from canada next
weekend. This trough will also sweep a strong cold front
through the southeastern conus, and into the florida
peninsula Saturday night and Sunday. Although it is still
too early to nail down the exact impacts of this front,
showers and storms are expected to develop ahead of the
front, and temperatures are currently forecast to drop to
near normal by Sunday afternoon.

Aviation
Vfr and rain free conditions are expected to continue
through the next 24 hours. Winds will generally remain
easterly, with a limited sea breeze turning winds onshore
at terminals near the coast during the afternoon.

Marine
The high pressure ridge axis will hold just north of the
gulf of mexico through the week, with generally easterly
winds continuing. A weak afternoon seabreeze will setup each
day, allowing winds to turn onshore near the coast.

Isolated to scattered showers and thunderstorms will be
expected over the coastal waters each day starting
Wednesday, with locally hazardous boating conditions
possible in the vicinity of some of the stronger storms.

Fire weather
No concerns, as humidity will remain well above critical
levels through the period.

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.
