Discussion
Summer continues as atlantic surface high pressure remains in
possession of south florida's synoptic pattern. Warm temperatures
are expected again today (and through the next week) along with
sea breeze development that will allow showers and thunderstorms
to form as well. A slightly drier atmosphere compared to previous
days and less mid level support for convection will point towards
boundary collisions between the sea breezes, convective outflow,
and remnant boundaries as the main focal points for convective
activity today. The hail threat appears to be minimal but one
cannot rule out the threat of strong wind gusts and the ponding of
water on roads from heavy rainfall today.

As we start ascending through the atmosphere, the mid and upper
levels show high pressure stretched across the gulf of mexico
while a mid-level trough related to a low pressure system over
the eastern two-thirds of the united states continues its eastward
progression into the great lakes and canada through mid-week. A
moisture boundary associated with the trough amplifying into the
southeastern united states will focus moisture over the peninsula
of florida which should allow for fairly healthy rain chances late
week into the weekend. As the mid to upper level system moves on,
high pressure will attempt to build back at the mid-levels over
the mid-south united states. The distance between this mid-level
high and south florida combined with the amount of available
moisture in the region could lead to a more unsettled pattern
capable of producing convection not only with the diurnal heating
cycle but also overnight.

As the extended period draws to a close, another mid-level trough
will push east across the nation with an amplification southward
along the way. It's still way too far out in the forecast period
to discern more than general trends with this trough but it does
remind us that soon the transition of seasons will begin to our
north which could lead to mid-latitude features pushing further
south that allow tropical moisture to focus over the region. At
this point however, the forecast has no such features or any
tropical concerns for the next 7 days for south florida.

Marine
High pressure will remain through the week with showers and
thunderstorms capable of producing strong wind gusts, locally
higher seas, heavy rain, and lightning. Otherwise, no headlines
are anticipated for winds or seas through the week.

scattered low clouds and light winds will prevail tonight. Aft
20 1500z, southeast winds will increase along the atlantic coast
to around 11 kt. A gulf coast sea breeze should also develop,
affecting kapf with brief west southwest flow. Expect vcsh during
the morning, with vcts developing during the early afternoon. By
20 2200z, most activity should have pushed westward over the
interior and gulf coast region. Winds and shower storms are
expected to dissipate this evening.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
