Update Isolated to scattered showers and also a couple of
thunderstorms continue across the southeast zones as a strong
mid upper level shortwave passes through the area. Best forcing
is moving offshore this morning and expect shower activity to
move east with perhaps a couple of light sprinkles possible over
the southeast zones about 11am-3pm near low level troughing.

Skies will continue to improve with mostly sunny to partly cloudy
today... With most of any low level moisture mainly southeast
zones. Temps will rise quickly as warm air just above the sfc
mixes down with highs just above normal today. Highs in the lower
to mid 60s over the ERN zones with lower 70s over the interior
areas.

Aviation
Vfr conditions will prevail today with ceilings at or above 10,000
feet through the morning hours. Some cumulus clouds around sgj
this aftn early evening but likely to be above MVFR. Any showers
this morning will remain south of the TAF sites. Low clouds are
expected to lift north into the area tonight and ifr conditions
cannot be ruled out prior to sunrise, but confidence remains too
low to add to the tafs at this time.

Marine No significant changes for today. Winds relatively
light and variable at 5-10 kt will be east to northeast at 5-10 kt
this aftn. Seas around 2-3 ft with dominant period around 10
seconds. Included a few storms over the SRN waters for the morning
update.

Rip currents: low risk given surf heights generally below 2 ft.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
