Aviation
A approaching cold front will bring increasing instability to the
region, allowing for the chances of shra and TS to increase later
this morning. Some of the TS may be strong with gusty wind, and a
very slight chance of a tornado, mainly north of a line from
apf over to pbi. The frontal passage currently looks to be late
this afternoon, into the evening hours.Behind the front, the wind
will shift to the northwest for the overnight hours.

update...

a few brief showers moved across the atlantic metro areas during
the early evening hours as prevailing southerly flow keeps
advecting moisture from the caribbean and the western atlantic.

Cloud cover and shower coverage will increase overnight, with
highest chances during the mid morning hours, starting around 10
am through noon on Thursday over the gulf areas, and through the
early afternoon hours for the atlantic metro areas.

breezy SE winds will strengthen and become S tonight as surface
high pressure slides further off to the east ahead of an
approaching cold front. This cold front will push through the area
tomorrow with showers and thunderstorms possible both along and
ahead of the front. The latest guidance has been trending earlier
with the frontal passage. The timing is now looking more like 5
am to noon for the gulf coast through lake okeechobee to 10 am to
4 pm for southeast florida. This timing may speed up a little
more as we get closer to the event if current trends continue. The
primary threats associated with these storms will be isolated
strong wind gusts, lightning, and perhaps a brief tornado or two.

The storm prediction center has portions of south florida from the
gulf coast through lake okeechobee outlooked in a marginal risk
for severe weather tomorrow to account for these threats. The
front and associated showers and thunderstorms should be pushing
out of the area by mid afternoon tomorrow.

Nw to N winds are expected in the wake of the front as high
pressure settles in over the southeast us. This will allow colder
air to filter in over the area once again, with Friday
night Saturday morning the coldest of the forecast period. Low
temperatures Saturday morning are forecast to range from near 40
west of lake okeechobee to the mid 50s along the east coast metro
with wind chills in the mid 30s to the low 50s across those same
areas. By Sunday the high expands eastward, allowing our winds to
become more easterly just in time for the next system to approach
the area. The details with this next system are still a bit
unclear, but for now it looks like some kind of surface low or
elongated trough over the gulf will push across the area from
west to east around Monday. This will likely bring another round
of showers and thunderstorms to the area late Sunday through
Monday night.

The next cold front will push through the area around midweek
next week. Not a lot of precipitation is expected with this front
as it doesn't look like enough moisture will be able to return to
the area prior to its arrival.

Marine... A persistent southeasterly flow will continue through
today with advisory conditions continuing over the atlantic waters
and offshore gulf waters. The wind should begin to diminish over
the gulf waters late tonight into early Thursday morning, allowing
conditions to slowly improve. Increasing shower and thunderstorm
activity is expected on Thursday as a front moves across the
region. A brief dry period is expected Friday and Saturday before
the next disturbance arrives on Sunday into Monday.

Beach forecast... A high risk of rip currents remains along the
atlantic beaches today and Thursday due to breezy southeast winds
and elevated surf.

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.
