Aviation (for the 00z tafs through 00z Monday evening)
issued at 649 pm cdt Sun sep 23 2018
progressively invading cloud cover and spotty showers is forecast
for late tonight, starting in our SE counties and advancing north
and northwest during the morning into early afternoon. The overall
coverage of rain looks to be in the chance category, based on
most high resolution models, so only used vcsh in the tafs for
late morning through afternoon. A break in the rain is projected
for late afternoon, but MVFR or ifr clouds will remain in place
for the balance of the afternoon, after developing in the mid-late
morning.

Winds will be e-se for most of the next 24 hours, with wind speeds
primarily below 10 kt.

Ilx watches warnings advisories

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.
