Near term through tonight ...

high pressure will be southeast of the region this period. Away from
the immediate atlantic coast prevailing winds will be southwesterly.

With this flow, expect the gulf coast sea breeze to push well
inland, with convection developing along it as it moves northeast.

The east coast sea breeze will likely not push much past i95, so
there could be a sea breeze collision with a few stronger storms in
the i95 corridor later in the afternoon. Temperatures will be above
normal today, except near to below normal southwest where clouds and
precipitation coverage will increase earlier in the day. Convection
is expected to dissipate this evening, with the loss of diurnal
heating, with clouds decreasing through the night.

Short term Sunday through Monday night
Deep layered ridge centered over the western atlantic will
stretch across the florida straits to southern florida through the
short term period. An upper low is forecast to be across the
northern gulf coast near the border of tx la, and a shortwave is
forecast to be east of the region over the western atlantic on
Sunday. The shortwave east of the region will lift northeast, and
the upper low will weaken through Monday. Deep west to
southwesterly flow will strengthen through Monday.

Convection is likely to be ongoing across the gulf coast and
suwannee valley region Sunday morning, and then quickly spread
eastward across the rest of the region. Similar conditions are
forecast for Monday. The east coast sea breeze will be pinned to
the east coast due to the west to southwest flow. Showers and
storms will end in the early evening each day, but showers storms
will redevelop along the gulf coast overnight and towards
daybreak. 40-60% rain chances are forecast each day. High
temperatures will generally be in the upper 80s to lower 90s, with
heat indices around 100f. Overnight lows will range from the low
to mid 70s inland to the upper 70s to near 80 at the beaches.

Long term Tuesday through Saturday
Deep-layered atlantic ridging will extend across south florida or
the florida straits through much of the week. The weather pattern
on Tuesday will be very similar to Sunday and Monday under the
deep west to southwest flow. Weak troughing will then be over the
region from the middle to the end of the week, with shortwaves
extending from the florida panhandle to the coast of north
carolina. Deep tropical moisture will be across the region with
precipitable water values of 2+ inches. Temperatures aloft are
forecast to warm through the end of the week, which would lead to
less lightning. Cloud cover from the shortwaves over the region
may also lead to lower rain chances Thursday into the weekend. A
strong upper low and trough will then carve out across the eastern
conus by next weekend.

Scattered to numerous showers and storms are forecast Tuesday and
Wednesday, with storms beginning along the gulf coast and pushing
towards the east coast in the afternoon. Scattered showers and
storms are then forecast into next weekend. Temperatures are
forecast to be near normal.

Aviation
PrevailingVFR conditions are expected this 06z TAF period.

Convection is expected to spread northeast across the region from
the gulf today, which could produce brief restrictions.

Marine
High pressure will be southeast of the region through the weekend.

The high pressure ridge will be east of area waters early next week.

A trough of low pressure will slide southeast across the region mid
week, and dissipate.

Rip currents: moderate risk today, low risk Sunday.

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.
