A tight pressure gradient will prevail over the local atlantic that will generate a moderate to fresh southeasterly breeze on Saturday. These winds will maintain poor to hazardous seas for most of the upcoming weekend. Winds will diminish to a moderate east-southeast breeze on Sunday as the ridge axis gradually weakens over the western atlantic.

Discussion
Tonight-sat... Highly amplified mid/upr lvl flow pattern over the
conus will prevail for the next 24-36hrs as a deep lyr short wave
trof over the central plains works its way into the midwest. Ridging
over the ERN seaboard will be reinforced by warm swrly flow from the
gomex/deep south, which in turn will keep an h100-h70 high pressure
stacked over the SE conus/wrn atlc nearly stationary. Meanwhile, a
short wave trof will riding over the NRN flank of the ridge will
gradually erode it, allowing a tight low/mid lvl pgrad around the
base of the ridge to slacken. Brisk easterly flow will diminish as a
result, bcmg e/se flow by daybreak sat.

These winds will tap a relatively dry/stable airmass over the w
atlc... Pwat values btwn 0.75"-1.00", h85-h70 lapse rates 3.0-
3.5c/km. H100-h85 mean rh values along and upstream from the
treasure coast btwn 70-80pct are just high enough to squeeze a few
light coastal shras out of the airmass overnight, but measurable
precip will be limited to the immediate coast and only a few
hundredths at best... Total coverage AOB 20pct.

The onshore flow will maintain mild temps acrs central fl... Though
marine influence will decrease along with the weakening sfc/low lvl
winds. Overnight mins in the m60s along the coast, u50s/l60s
interior. Aftn maxes in the m70s along the coast, u70s/l80s
interior.

Saturday night... East central florida will be between a couple of
mid level lows, one over the bahamas and another lifting NE over the
central plains with a wedge of upper ridging over fl peninsula. In
the low levels, the high pressure ridge to the north over the
western atlantic will maintain an onshore (e/se) flow. Model
soundings show considerable dry air in the mid levels but
considerable high clouds may filter the sunshine. Some fair weather
cu possible below the strong subsidence inversion near 850 mb which
could produce more clouds than sun. Rain chances will be too low to
mention.

Sunday-Thursday... (prev disc)
weather looks rather tranquil as mean layer ridging remains nearby
and a couple of mid/upper level disturbances pass to the north of
the peninsula through the period. As a result, rain chances will
remain quite low and are not mentioned in the extended forecast.

With no significant frontal passages or intrusions of cool air, high
temperatures will be above normal in the low 80s coast and mid 80s
interior with a few upper 80s possible late in the week. Lows will
be a little more seasonal in the upper 50s and lower 60s.

Marine
Tonight-Saturday... A strong high pres ridge centered off the
carolina coast and trailing back into the deep south will maintain
poor to hazardous boating conditions for the next 24-36hrs. Fresh to
strong e/se breeze overnight bcmg moderate to fresh by daybreak sat
as the ridge slowly weakens over the W atlc. Seas 5-7ft nearshore
and 7-9ft offshore early this evng, subsiding to 4-6ft nearshore and
6-7ft offshore by midday sat.

Extended though Tuesday... E/se pressure gradient will slowly weaken
Sunday and Monday supporting wind speeds around 10 knots, veering
southerly Tuesday. Seas however will remain near 6 feet due to long
period swells thru early next week. This should produce hazardous
conditions near inlets for small craft especially during the
outgoing tide. So will likely need a caution for all marine zones.

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.
