What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

on mon, will see some weak onshore NE flow develop for awhile
along the coast. By aftn as the flow aloft shifts from the W to
the wsw... Expecting increasing moisture ahead of the next
approaching systems from the S and w. Partly sunny-mostly
cloudy W pops by afternoon rising to 30-50% (far) wsw tier
counties... While remaining AOB 15% toward the ERN shore. Highs
in the 70s at the coast to the l80s inland.

Warm front pulls N of the region Mon night (w possible sct

any lingering showers t-storms move south of the area by Thursday

from Saturday afternoon through the remainder of the weekend.

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.
