304 am edt Tue apr 24 2018

Near term (today and tonight)
Cold front is pushing east across the area this morning and will
lower humidity levels today. Dry air in the mid-upper levels has
wrapped around deep layered low pressure to the northwest so no
precipitation is expected. Temperatures will be near average today
and tonight with gusty west southwest winds this afternoon.

Short term (Wednesday and Thursday)
Wednesday will be similar to today with west winds behind a
departing low pressure system to our north. Highs in the upper 70s
to low 80s are expected. Thursday also will be pleasant for the
most part, though winds will shift southwest and a broad area of
low pressure will develop across the southeast as a shortwave
trough moves through the tennessee valley. Other than just along
the altamaha river where we have just low end chance pops, this
area of low pressures should pass north of with little in the way
of rain for our area.

Long term (Friday through Tuesday)
A weak trough will remain in the wake of the low along the coast.

This could contribute a few showers on Friday, but for the most
part the remainder of the long term also looks dry. Upper level
trough will move through the eastern CONUS Saturday and strong
high pressure across the eastern great lakes will filter into the
area from the north. Upper level ridge will build to our west
Sunday and over the southeast by Tuesday, keeping high pressure in
place to start the workweek. Onshore flow will increase on Monday
and Tuesday which will moderate temperatures close or just below
normal for the beginning of may.

Aviation
Patchy low clouds moving east across NE fl will produce brief
periods of ifr MVFR CIGS until around 14z.VFR conditions will
prevail today with southwest winds.

Marine
Advisory will continue today offshore due to elevated seas. Low
pressure will track to the NW of the area with a cold front
crossing the region this morning. The low will track up the east
coast Wednesday with decreasing offshore winds and seas the next
few days.

Rip currents: moderate risk today and low risk Wednesday.

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.
