338 pm edt Sun apr 22 2018

Short term (tonight-Monday)
Scattered showers and thunderstorms continue to move northwestward
across the eastern half of the peninsula and into the central part
of the state. As the west coast sea breeze forms and starts to push
away from the coast, expect additional activity to pop up, with the
greatest areal coverage still expected near the i-75 corridor. Most
of this rainfall will come to an end by around midnight or so. Having
said that, rain chances will still be in the forecast overnight due
to an approaching area of low pressure and associated cold front.

This front will still be well to our northwest by daybreak tomorrow,
with a steady southerly flow in place across the area. Overall, it
will be a pretty muggy night, with lows only in the mid 60s to lower
70s and dew points not far off from those values.

For the rest of Monday, the frontal boundary will make its way into
the northern part of the peninsula, with the highest rain chances
for our area across levy county. An increasing southwest flow
through the day will then allow the highest rainfall coverage to be
over the interior and east coast of the state. As the boundary will
not have passed through the region by the end of Monday, conditions
will remain on the warm and muggy side.

Long term (Monday night-Sunday)
Deep upper-level trough and associated cold front will be moving
slowly east southeast through the region Monday night and Tuesday.

The upper-level trough will move east of the peninsula Wednesday
night and Thursday. Another system will impact the area in the
Friday through Sunday time frame, but models are still having issues
resolving the southern stream energy dropping out of the mid-west
toward the northern gulf coast on Wednesday.

Showers and thunderstorms will be ongoing Monday night ahead of the
surface cold front and associated upper-level trough. Rainfall
chances will increase as we head through Tuesday with some surface
heating resulting in more surface-based convection. Still, shear and
stability are both lacking with this system, so while we could see a
few strong storms, no severe storms are expected.

Drier air will move in for Wednesday and should hold into Thursday
as well. A weak upper-level disturbance is forecast to pass north of
the region, but impacts should remain well north of our area.

The next system to impact our weather will arrive over the weekend.

Confidence in timing and extent is very low as global models are not
showing any consistency with upper-level features. Will continue to
keep rain chances at or below 30 percent, but just like yesterday,
the ECMWF is much wetter indicating a frontal boundary and upper-
level trough over the region Saturday night and Sunday.

Aviation
Periodic MVFR ifr CIGS and or vsbys will be possible with scattered
showers and thunderstorms moving across the region today. These are
currently across the east coast and parts of the interior, moving
toward the northwest. The best chance for these to affect the
coastal sites will be starting around 19-20z, possibly lingering
until 01-02z and will include a tempo group from 20-22z to account
for this possibility. Light southeast winds tonight will become more
south to southwest through tomorrow afternoon.

Marine
A frontal boundary will approach the region tonight into Monday,
with winds becoming more south to southwest along with increasing
chances for shower and thunderstorm activity. This front will move
through the region late Tuesday, with drier conditions and west to
northwest winds behind it for mid week.

Fire weather
No fire weather concerns for the next several days as relative
humidity values will remain above critical levels. Some patchy
ground fog will be possible tonight, but no widespread or dense fog
is expected.

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.
