Synopsis..High pressure will continue to build across the eastern gulf of mexico through the rest of the weekend with generally east to southeast winds that turn onshore each afternoon with the sea breeze. Nocturnal surges will bring winds up to cautionary levels during the late night and early morning hours. Winds will then relax during the early part of the week as a cold front washes out across the area.

Short term (today - Sunday)
High pressure will continue to dominate the area this
weekend, with an omega ridge aloft holding in place over
florida and the western atlantic, and a surface ridge
centered off the carolina coast drifting slightly north
through Sunday. Rain chances will be suppressed under the
effects of this ridging, despite the fact that southeasterly
low level flow will continually increase atmospheric
moisture and humidity. Otherwise, a fairly tight pressure
gradient along the southwestern edge of the surface ridge
will produce somewhat breezy winds across the area, which
will in turn limit the west coast sea breeze from making a
solid push inland.
Temperatures will continue to run well above normal, and
similar to Friday, a few new record high temperatures may
be set this afternoon. With increasing humidity and a few
more clouds on Sunday, temperatures will moderate by a
couple of degrees, but highs are still forecast to reach
into the upper 80s and low 90s.
Mid term/long term (Sunday night - Friday)...
an upper low over the central plains Sun night troughs down
to northeast mexico and has a surface reflection that
trails a cold front down the mississippi valley to the gulf
Through Tue - the upper low and it/s trough tracks
northeastward... Dragging the front into northern fl. Upper
ridging builds north over the gulf of mexico with zonal flow
weakening the front and allowing surface high pressure in
the atlantic to continue to ridge across fl.
On Wed - zonal flow continues aloft the gulf as a weak
short wave trough slides through. The weakened front lifts
north while the surface ridge reaches across the gulf.
Thu-fri - an upper level trough forms from the mid-west to
west tx then moves east... From the great lakes to the
eastern gulf of mexico... With an associated cold front
reaching northern fl and the east gulf fri.
The frontal system early in the week... The short wave trough
mid-week... .And a second and somewhat more robust front at
the end of the week will keep skies partly cloudy and|
support a slight chance to a chance of showers with a few
thunderstorms. Temperatures initially run above normal but
then decrease to around normal by Fri due to the clouds and
rainfall. Prevailing light southeast and south winds... With
afternoon sea breezes... Continue until Fri when they become
westerly and increase some.
GenerallyVFR conditions are expected to hold through the
next 24 hours. Some isolated areas of MVFR ceilings have
so far stayed away from area TAF sites, but it is possible a
few more pockets will develop through sunrise. Otherwise,
breezy southeast winds will keep the sea breeze limited.
High pressure will continue to ridge from the atlantic into
the northeastern gulf of mexico into Monday, with
southeast flow giving way near the coast each afternoon to
onshore flow with the sea breeze. Nocturnal surges will
bring the wind speeds up to around small craft exercise
caution levels. A cold front will creep into the waters late
Monday and wash out through the middle of the week, with a
few showers and storms possible, but winds are otherwise
expected to remain less than 15 knots.
Red flag conditions will be marginal this afternoon, with
breezy winds of around 15 mph and relative humidity
dropping to around 35 percent. Although it is possible that
a few sites will see instantaneous red flag conditions,
confidence is not high enough to issue a red flag warning at
this time. Humidity is forecast to gradually increase
Sunday and Monday.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
