Update
Upper level ridging will build in over the region in the
wake of yesterday's upper level trough and cold front as
surface ridging builds down the eastern seaboard. A very
dry stable air mass via 12z RAOB data across the forecast
area will support pleasant dry weather today with ample
sunshine expected. Despite the ample sunshine though cool
air advection will keep temperatures below normal with highs
only reaching the mid upper 50s across the nature coast and
lower to mid 60s central and south. Ongoing forecast is in
good shape with no morning update required at this time.

Aviation
Vfr will prevail at all terminal sites during the next 24
hours with northeast winds AOB 10 knots.

Marine
Winds via c-man and offshore buoys have dropped below
advisory criteria this morning as high pressure builds in,
however seas will take a while longer especially over the
offshore waters where cautionary headlines will be depicted
for the remainder of the day with north-northeast winds
around 10 knots closer to shore slowly veering to the
northeast during the afternoon. Will add cautionary
headlines for the offshore waters in the next forecast
issuance around 10 am to account for the residual elevated
seas, otherwise the rest of the forecast is on track with
no other changes planned at this time.

Fire weather
A very dry air mass over the region will support 3 to 4
hours of humidity values below 35 percent over portions of
the forecast area this afternoon, however lighter winds
combined with low erc's will preclude red flag conditions.

An increase in moisture is expected on Tuesday as the flow
veers into the east with no other fire weather issues
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.
