SHORT TERM. (Issued 215 PM CST Fri Dec 4 2020)

Tonight through Sunday:

A pair of shortwaves will drop through Saturday night and again Sunday night, possibly bringing a few flurries to southern Wisconsin. Expect increase clouds as these waves move through as well. Otherwise, quiet weather will continue through the weekend with temperatures near normal for early December.

DDV

LONG TERM. (Issued 215 PM CST Fri Dec 4 2020)

Monday through Friday:

High pressure overhead Monday into Tuesday will gradually shift southeast into mid-week as a trough of low pressure approaches. A switch to southerly low level flow will allow temperatures to warm up a bit through Wednesday, with high temps at least 10 degrees above normal by mid-week.

Quiet weather is likely to continue through Friday, though a weak wave may bring a little light precip late in the work week. Temperatures will probably be a bit cooler for the second half of the week behind the mid-week trough, but still look at least a few degrees above normal.

DDV

AVIATION. (Issued 215 PM CST Fri Dec 4 2020)

A few clouds may continue to fill in across the eastern forecast area later this afternoon into the evening behind a departing cold front. May see brief MVFR conditions into the evening, but most places should remain VFR. Clouds should largely clear out for tonight and Saturday as high pressure builds into the area.

DDV

MARINE. (Issued 215 PM CST Fri Dec 4 2020)

High pressure will continue to build into the northwest Great Lakes into Saturday. Northerly winds will persist into the weekend while gradually becoming lighter. Winds will stay on the lighter side for at least the first half of next week.

DDV

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 numerous 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.
