307 am edt Mon oct 21 2019

Discussion
An upper level ridge is building in across the region as a weak
"warm" front is beginning to lift across the peninsula, leading to
increased mid-level cloud cover to start off the day. Coupled with
diurnal heating, the weak forcing is expected to lead to scattered
showers, primarily around tampa bay and northward. While a
thunderstorm is not impossible today, the likelihood seems low,
given the thermodynamics of warm fronts and also the fact that the
atmosphere is warm. Last night's sounding showed the o-degree
celsius line to be around approximately 550mb (21,000ft). This is
nearly halfway through the troposphere. Model data continues to
support this trend continuing during the day.

As Tuesday arrives, another front will be approaching the area,
dragged by a trough axis beginning to negatively tilt over the great
lakes region. This will keep rain chances in the forecast, but
overall the front is expected to hit a wall and weaken substantially
over the central part of the state. From about tampa bay northward,
a hint of fall will be in the air, especially Wednesday morning,
but most of SW florida will barely notice the system. Drier air
will funnel into the region, though, leading to a more comfortable
day. This will not last long, however. Temperatures will warm
back up again on Thursday and moisture returns with scattered
showers and isolated thunderstorms possible.

By Friday, another front will be approaching the peninsula as
shortwave trough axis negatively tilts over the great plains and
propagates in a general ene direction. There are some timing
differences in model guidance at this point, but a generally
unsettled weather pattern is expected through the weekend as the
frontal system destabilizes the atmosphere around it in tandem
with the synoptic-scale ascent mechanisms accompanying the front.

This will keep decent rain chances in for the latter part of the
forecast period, but also slightly lower temperatures with the
increased cloud cover.

Aviation
In generalVFR conditions are expected to prevail throughout the
forecast period. With a very weak warm front making its way
northward, northern terminals do have vcsh in the tafs to account
for the convection that is expected to develop this morning closer
to the coast and make its way more inland by the afternoon. While a
thunderstorm cannot be ruled out, conditions are generally not very
conducive for thunderstorms, but more showery weather. Winds will
remain light through the early part of the day from the se, but will
become more SW during the afternoon around 6-10kts.

Marine
Scattered showers and isolated thunderstorms are expected this
morning in coastal waters. While seas are expected to remain in the
1-2ft range through the morning hours with light SE winds, showers
could cause higher seas and winds for brief periods. In general,
conditions will remain more or less the same through Wednesday,
before higher ene and eventually E winds and seas come back into the
forecast. Cautionary statements may be needed mid-week to account
for the higher winds and seas. Weather conditions will remain
somewhat unsettled into the weekend, making the latter part of the
week less favorable for boating.

Fire weather
Fire weather concerns remain low as values remain above critical
levels through the week.

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.
