upper level low over central eastern va this afternoon will
slowly lift NE thru early evening, and will be accompanied by
sct-likely shras. Best likelihood appears to be south east of

A quick increase in pops (to 50-80%) Thu night as lo pres enters
the fa from the sw. Keeping pops 50-70% NE half of the fa fri

late Fri night with it moving off the sern coast Sat ahead of a weak
frontal passage. Meanwhile, the ECMWF is drier with little if any
support for pcpn even with the frontal passage sat. A model blend
results in low chc shwrs across the sern zones late Fri night and
sat keeping the rest of the local area dry for now. Lows Fri nite
upr 40s-mid 50s. Highs Sat upr 60s-mid 70s, cooler at the beaches.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
