Update
Convection has begun to wind down with just some patches of light
rain expected for the next few hours. Later tonight mostly clear
to partly cloudy skies are expected as the mid high level debris
clouds gradually dissipate. However, with many areas seeing some
rain today and a light north to northeast flow overnight would not
be surprised to see some areas of low clouds and patchy fog
develop toward morning, especially from around the interstate 4
corridor northward. For the rest of Monday we'll see a northwest
flow develop and with some drier air moving in from the north
during the day the rain chances will be lower, 30 percent or less,
with best chances over the interior. Current forecast looks on
track with no evening update needed.

Aviation
Scattered convection will continue to wind down this evening. Then
overnight and toward morning some patches of low clouds may
develop and mainly effect areas around lal, otherwise mainlyVFR
conditions are expected for the forecast period. During Monday
afternoon an isolated shower or thunderstorm will be possible,
but overall chance too low to include in terminal forecasts at
this time. Light north to northeast winds overnight into Monday
morning will shift to northwest and increase to between 7 and 12
knots during Monday afternoon.

Marine
Weak high pressure will hold over the region for the early
portion of the week with generally light winds and seas. During
midweek a weakening cool front is expected to push through the
region with stronger high pressure building in from the north
bringing increasing winds and seas for the second half of the
week. Wind speeds are expected to reach exercise caution criteria,
possibly advisory levels, during the second half of the week.

short term...

a complex synoptic pattern is currently in play across the region
complements of an upper-level low to the west and tropical storm
humberto to the east. Sandwiched between these two features, a weak
trough axis is draped across the florida peninsula, helping to steer
humberto off to the northeast around the subtropical high.

Similar to dorian a couple weeks ago, humberto is influencing the
flow across the region at the surface. As winds rotate
counterclockwise in a cyclonic fashion, winds are out the of nne for
northern regions, then gradually turning to a more nnw flow
across the southern region of the state. Humberto is caught in a
larger easterly flow pattern at the surface that has been
advecting a large plume of tropical moisture from the western
atlantic, across the peninsula, and ultimately across most of the
gulf. Subsequently, coastal areas are continuing to see more of a
ne flow despite humberto's influence as the upper level low in the
central gulf fights for moisture and energy from the environment.

With ample moisture and a fairly unstable environment, showers and
thunderstorms are developing this afternoon across the region, on
track with this morning's forecast as expected. The highest rain
chances will be concentrated in and around tampa bay extending east
into the interior counties primarily south of i-4.

As humberto continues to move away from the florida coastline, the
pattern will begin to shift to a drier one. The nne wind will
no longer be advecting tropical moisture for humberto over the
region, but drier continental air making its way down from the
conus. Combined with the strong subsidence (sinking air) from
humberto, a dry start to the work week is anticipated.

Long term...

drier conditions will continue through the rest of the work week.

By Wednesday, a "cold" front is expected to enter the scene. While
only contributing a miniscule drop in temperatures, surface
dewpoints are expected to drop significantly. Lower dewpoints will
make conditions feel much more comfortable than usual.

Unfortunately, this too shall pass. By the weekend, a more typical
late summertime pattern is expected to return as easterly flow
brings moisture back into the region and temperatures go back up.

Scattered showers and thunderstorms are expected to return by
next weekend.

Fire weather...

scattered showers and thunderstorms are possible across the region
in the afternoon and evening hours. By tomorrow conditions begin to
dry out and will remain drier through the entire work week. Despite
the drier conditions, sufficient moisture will be present to keep
relative humidity levels above critical thresholds.

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.
