Aviation
Vfr conditions will prevail at all of the terminals through the
forecast period. The biggest concern will be thunderstorms
developing between 18z and 00z today that could impact any of the
terminals for brief periods of time. Have included vcts wording to
reflect this risk at most of the terminals. However, at khum, have
included a couple of hours of MVFR visbilities and prevailing
thunder in a tempo group as rainfall probabilities currently are
highest at this terminal for this afternoon. The biggest concern
with any convection will be strong gusty winds and wind shear near
the thunderstorms as well as periods of ifr visibility
restrictions as the storms move through. 32

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
