Aviation
Main concerns will be with frontal passage this evening through
all terminal locations. Timing appears to be around 03z for
western terminals through 06z for eastern terminals with wind
shift and increased gustiness. Some temporary low level wind
shear considerations with frontal pasage but not enough to warrant
inclusion. Rainfall may be limited along front due to limited
instability and lightning is not anticipated.VFR conditions
should prevail for much of the valid TAF period. 24 rr

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.
