Update
Smoke and ash was affecting portions of charlton and nassau

as the inversion breaks.

Low level moisture on the backside of low pressure across north
carolina will shift to the east and northeast today, with mostly
sunny skies across the region by the afternoon. Westerly winds
will prevail, and after a cool start, temperatures will rebound
into the low to mid 80s.

Aviation
Vfr conditions will prevail through the period. Wrap-around low
level moisture on the backside of low pressure across north
carolina will lift to the northeast today, with clearing skies
through the afternoon. Westerly winds around 10 knots with gusts
to 20 knots will prevail this afternoon. Light and variable winds
are expected tonight.

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.
