Update
Upper trough southward through the great lakes keeping wsw
flow aloft over the region and stream of cirrus overhead
from mexico. Weak surface pressure gradient to allow light
and variable winds overnight with dew points in the 60s to
produce some locally patchy shallow fog in fog prone fields
and low lying areas with above average temps. Guidance
suggests small vort MAX to move over the area starting
Tuesday morning providing enough lift for some light rain
showers as well. Latest grids and forecasts on track.

Aviation
Light winds and mainlyVFR conditions expected overnight
with the exception of shallow field fog in prone areas at
klal, kpgd, and krsw. Light showers possible Tuesday.

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.
