Aviation Vfr conditions expected for the net few hours but by
12z we should begin to see some low clouds build and then the cold
front is expected to quickly surge through the area through the
late morning hours and should be through all of the terminals
before 18z. MVFR CIGS will begin to develop from northwest to
southeast beginning around 15 16z by mcb and btr. Precip should
begin to slowly develop and fall over the area also from northwest
to southeast and should begin as either light rain, maybe even
light freezing rain but more likely as sleet at btr and mcb and
then likely quickly switching to snow at mcb between 18-20z and
likely around 19-21z at btr. All terminals will likely show some
frozen precip tomorrow afternoon and into the evening hours. Cab

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.
