Update
Marine Light sly winds will continue tnt into Tue with modest
nwly winds to develop Tue nt-wed with the passage of a cold front.

Wind gusts may reach into the lower 20 knot range.

Prev discussion (issued 705 pm cdt Mon sep 25 2017)
update... Showers and isold tstorms west of madison
have been mostly initiated by outflow boundaries from previous
convection. Expect the showers and storms to gradually weaken over
the next few hours but may not completely dissipate as the sfc
trough is nearby. Pressure falls will occur over NW wi tnt with
low pressure developing newd across lake superior on tue. Thus the
cold front will slowly progress ewd across SRN wi. Dynamics and
heights falls will be very minimal on Tue as the main upper trough
over the NRN and central rockies lifts newd into the NRN great
plains and canada. The sfc convergence along the broad front will
be weak as well, thus only chances of showers and tstorms on tue.

Aviation(00z tafs)... Areas of fog may form late tnt mainly west
of madison where rainfall has occurred this evening. The passage
of a cold front on Tue will bring chances of showers and tstorms
but the lowest CIGS should remain from 5-7 kft.

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.
