Discussion
Today-tonight... A strengthening deep layer high pressure ridge will
build from the ms valley this morning across the eastern conus
today, then elongate and extend eastward into the western atlantic
by tonight. As this occurs, another elongated short wave trough will
drop southward along the eastern flank of the ridge, similar to what
took place a little farther NW about 36 hours ago. Also like that
event, a piece of its western flank will pinch off into a sw-moving
mid-upper low that begins to cutoff over south florida by Friday
morning.

This pattern will cause surface ridging to develop and strengthen
over the western atlantic, with freshening onshore flow by late this
afternoon and continuing into tonight. Global and mesomodel guidance
continue to show minimal coverage of diurnal convection along the
east coast, but increasing from i-95 westward across the interior.

Pops will follow suit, ranging from 20 along the atlantic coast to
40-50 percent for the interior. Development of the upper low over
south florida tonight appears likely to enhance nocturnal shower and
thunderstorm coverage and intensity. As such, have raised pops into
the scattered category and kept mention of thunderstorms from the
cape southward across the treasure coast and inland to the lake o
region. Highs look to be a degree or two lower than Wednesday, with
maxes around 90f for the coast and 93-94f for the interior. Mins in
the m70s inland, u70s along the coast due to the developing onshore
flow.

Friday-Sunday... The mid upper level low will be in the process of
pushing westward across the southern florida peninsula Friday
morning. Cooler temps aloft associated with this feature and higher
moisture will exist across areas south of orlando, leading to higher
rain chances up to 40-50 percent across the treasure coast and
okeechobee county into the afternoon. North of this area shower and
storm coverage is expected to be lower, with rain chances around 30
percent. As low aloft shifts west, deep layer ridging north of the
area will continue an onshore flow across the area that will
increase moisture over central florida through the weekend. Easterly
flow will favor showers and isolated storms pushing onshore during
the overnight and morning hours, with scattered convection
developing and pushing inland through the afternoon along a diffuse
east coast sea breeze. Greatest coverage rain chances will be across
the interior each afternoon with pops up to 40-50 percent.

Increase in onshore winds will keep highs closer to normal values
through the period with values in the upper 80s, except low 90s over
far inland areas. Lows will remain mild in the mid 70s for many
locations, and upper 70s will be possible along the coast where
winds don't drop off completely overnight.

Monday-Wednesday... Low pressure currently east of the mid atlantic
is forecast to shift E SE and weaken into the weekend, with a ridge
building to the north of this feature and steering it back to the
west through early next week. Both models have this low over the
atlantic weakening to an inverted trough as it approaches east
central florida Monday. The GFS then has this feature moving through
the area Monday night into Tuesday, while the ECMWF has it recurving
just east of florida. The GFS solution would lead to an increase in
moisture and higher rain chances into Monday night Tuesday. Forecast
leans in this direction for now, and have increased pops up to 40
percent along the coast to 50-60 percent inland for Tuesday.

Otherwise scattered afternoon showers and storms generally expected
through early to mid week, with highs remaining near seasonable
values.

Aviation Vfr for the coast, and for the interior through about
18z-19z, with diurnal sea breeze convection developing increasing
in coverage through about 00z or so. Pattern will warrant limiting
mention of vcts to the interior 4 aerodromes (klee-kism-ksfb-kmco).

Marine Today-tonight. Minimal wind chop and continued 9-10sec
period swell of 2-3ft continues. Developing onshore ene-e winds
tonight will introduce a shorter period wind chop into the mix,
and bring combined seas up to 3-4ft.

Friday-Monday... Ridge north of the area will maintain an onshore
wind flow through the period, with E SE winds increasing up to 10-15
knots at times. Seas 3-4 feet Friday are expected to increase up to
5 feet offshore into the weekend.

Climate High temperature records for Thursday, september 20th.

Coastal record highs look to be safe, however the record high at
sanford will be approached again this afternoon.

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.
