southward over the great lakes and into the ohio river valley

canadian high pressure settles into the great lakes. Highs Thu in
the mid 70s. Highs Fri range from lower 70s over northern cwa

reach the mid to upper 40s, while highs 69-73f on Saturday.

A weather system moving east over the midwest Mon Tue could bring
isolated rain showers to the il river valley Monday night Tue but
fairly high upper level heights over CWA will keep most of area
dry. Temperatures will be warming during 1st half of next week as
southerly flow sets up with high pressure moving over new england

Monday and lower 80s tue. Cpc's 8-14 day outlook for oct 3-9th

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
