354 am edt Thu mar 30 2017

Short term
Another warm, dry day expected across the area as high pressure
remains in control of our weather. Surface high will shift eastward
during the day allowing winds to become more southerly by the
afternoon, although we should still have a sea breeze right near the
coast. Overall, there should be enough suppression from the ridge to
keep rainfall out of the forecast once again. Temperatures will
remain on the warm side with middle to upper 80s expected, a bit
cooler at the coast courtesy of the seabreeze.

On Friday, a mid/upper level trough will dig into the SE u.S.

Allowing a surface trough to move through our area bringing some
rain chances with it. Mid/upper level support will be moving away
from our area so will likely end up with a broken line of showers
and isolated thunderstorms moving through the area. But with as dry
as it has been the last few months, we will take any rainfall we can
get.

Long term
Progressive pattern continues with upper low over the NE us moves
into the western atlantic as upper ridging builds from the N carib
through the region. Surface high pressure moves N of the area with
low level flow quickly veering easterly bringing atlantic moisture
over the state for a warm and humid weekend.

Next system to move through thru the region next week with southern
stream upper low from the desert SW Sunday quickly moving through
the deep south mon/tue pushing surface storm system and attendant
cold front through area the with a chance of showers and
storms.

Aviation
Vfr conditions are expected through most of the overnight
period. However limited br mainly inland may impact the fog
favoring terminals at lal and pgd which have tempo MVFR toward
dawn. Winds increase from the SE in the morning... Then become
southerly with modest gusts in the afternoon.

Marine
Winds will become onshore with the sea breeze this afternoon and
into the evening. A more southerly flow will develop over
the waters today ahead of an approaching cold front, which
will bring shower and possibly some thunderstorm activity
for Friday. Winds this evening and into Friday could
increase close to cautionary criteria, otherwise no
headlines are expected. Lighter winds and drier conditions
return for the weekend as high pressure moves back over the
area.

Fire weather
Relative humidity values will fall near critical levels east of
the i-75 corridor for this afternoon and may briefly drop just
below 35%, but long durations are not expected and light winds
will preclude red flag conditions. Low-level moisture will
increase for Friday, and relative humidity values are expected
to remain above 35%.

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.
