Discussion
Today through Monday
Southeasterly winds aloft will prevail in response to anticyclonic
flow around the building western atlantic ridge. The upper level low
responsible for briefly wetter conditions will move away into the
central gulf of mexico. Surface ridging will be supported by the
upper high as it builds southwest into south florida while
maintaining the prevailing easterly low-level flow. Subsidence and
decreased moisture through the atmospheric profile should switch us
back to a more typical pattern of late night early morning atlantic
and east coast showers, followed by afternoon sea breeze driven
convection mainly over the interior. Given the easterly low-level
winds, the gulf breeze should have a tough time making it too far
from shore, leading to better convergence just inland from the
west coast once the atlantic sea breeze arrives collides by mid
to late afternoon. This should lead to better coverage of showers
and thunderstorms over the western interior areas during the
afternoon and early evening hours. High temperatures will be
seasonal and in the upper 80s to lower 90s both days.

Tuesday
A broad low pressure area now 200 miles south-southwest of bermuda
will be drawn poleward around the atlantic ridge to near offshore of
the carolinas. While the associated troughing should extend
southwestward towards florida, no appreciable increase in deep layer
moisture is suggested by the current deterministic model solutions.

Therefore expect a similar pattern to days prior with late
night morning atlantic east coast showers followed by mainly
interior west coast thunderstorms along the sea breeze. With the low-
level flow turning more southeasterly this could favor better
thunderstorm coverage from lake okeechobee south-southwestward
towards the naples area.

Wednesday through Saturday
The mid-level ridge will slowly retrograde across florida and into
the western gulf of mexico. Concurrently, the western atlantic
surface ridge will flex westward ahead of troughing advancing
through the southeastern CONUS by late week. The easterly flow
pattern should be maintained, along with the diurnal spatial shower
and thunderstorm trends described for the previous days. The
deterministic guidance do show some weak perturbations passing
through the mean flow, and these could lead to the occasional
uptick in shower and thunderstorm coverage at times. Temperatures
should remain seasonal, with values typical of late september.

Marine
Prevailing easterly winds are anticipated over the next several
days, with a gulf breeze along the west coast leading to afternoon
variable or west-southwest winds there. Speeds should average around
5 to 10 knots. A disturbance south of bermuda will push a 1-3 ft
northeasterly swell into the northeast local atlantic waters
(particularly off palm beach county) through the early part of this
week. Scattered showers and thunderstorms are anticipated, with
greater coverage favoring the atlantic waters during the overnight
and morning hours, and the gulf and lake okeechobee waters through
the late afternoon and evening.

Aviation
Drier air moving into the area will keep mainlyVFR in place
through much of the day. Vcsh may develop after 14z on the
atlantic terminals, and after 17z over apf as the west coast sea
breeze pushes inland. Light and variable winds prevail through
14z, then mainly ese flow will prevail from the late morning and
through this afternoon. Only exception will be apf as the
aforementioned sea breeze brings onshore flow in the 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.
