Short term
Tonight though Friday... Forecast confidence is high:
high pressure will exit to the southeast tonight into Thursday in
advance of a trough of low pressure. Skies will remain mostly
clear into tonight under the influence of the high, with
increasing clouds from the west later tonight into Thursday.

Should be mainly dry through the day Thursday, with maybe a shower
or two northwest toward evening. Better chance for showers will be
Thursday evening into Thursday night as the front pushes through.

Temps should be a few degrees above normal Thursday.

There should be a break in precipitation later Thursday night into
Friday morning between waves. A stronger wave is then expected to
move through during the day Friday, with showers likely. Could
even be a rumble or two of thunder during the afternoon. Temps
will be near to a few degrees below normal Friday and will likely
cool several degrees when the showers move in given the relatively
low dewpoints. The showers will wind down by late evening. Not out
of the question too see a few snowflakes at the buzzer later
Friday evening in the northern forecast area.

Long term
Saturday and Sunday... Forecast confidence is high:
dry weather is expected over the weekend under high pressure. It
will be cooler Saturday behind the departing cold front, with
temperatures returning to around normal Sunday, except for cooler
conditions near lake michigan.

Monday through Wednesday... Forecast confidence is medium:
the overall pattern for early next week suggests above normal
temperatures with an eventual chance for showers and
thunderstorms. The main challenge with this period is the timing
of the main cold front. Models with a faster front suggest temps
not as warm as the slower models along with earlier shower storm
chances. Would see temps push 80 if the slower model solutions pan
out.

Aviation(18z tafs)
Vfr conditions will continue through Thursday. Skies will remain
mostly clear into Thursday, with mid high level clouds increasing
from the west in the afternoon as a cold front approaches. A few
showers are then possible mainly Thursday evening and early night
as the cold front moves through.

Will have to watch winds near lake michigan tomorrow. Prevailing
winds may be strong enough to keep the lake breeze offshore into
early afternoon, but it seems the lake breeze will eventually win
out near the lake.

Marine
A small craft advisory remains in effect until 7 pm from port
washington southward as waves gradually subside.

Winds and waves could approach advisory levels again Thursday
night into early Friday, with a better chance for higher gusts
Monday and Tuesday.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory until 7 pm cdt this evening for lmz644>646.

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.
