Aviation(12z tafs)... A swly 45-50 kt LLJ will develop early this
evening and exit SRN wi from 05z to 07z late tnt. Thus llws is
likely once again. Otherwise, winds will gust around 25 kts from
late this morning through the afternoon. Mostly clear to partly
cloudy skies will continue withVFR conditions, although fog may
form early Thu am in the wi river valley.

today and tonight... Forecast confidence is high...
a shortwave trough will track across SRN wi and NRN il from late
this morning through the afternoon. Too dry for clouds or precip.
But it will contribute to the pressure falls and gusty winds
through the day. The breezy sswly winds will maintain a mild
airmass over the region with the low level thermal ridge settling
over the area this afternoon into the early evening. Went with
high temps similar or slightly warmer than yesterday. A dry and
weak cold front will then pass tonight with perhaps scattered
clouds with its passage. The winds will become light late tonight
as a ridge of high pressure approaches from the west. Areas of fog
are possible in the wi river valley.
Thursday and Friday... Forecast confidence is high:
high pressure will bring continued pleasant weather to southern
wisconsin to end the work week, with mostly sunny skies and above|
normal temperatures expected. Bumped temps up Friday a fair
amount above most models, as model surface temps aren't reflective
of the very mild airmass aloft.
Saturday and Sunday... Forecast confidence is medium to high:
low pressure and an associated cold front will approach the area
on Saturday, with models in fair agreement in the trough front
passage Saturday night. Pretty good surge of moisture ahead of
this system, with model precipitable water values rising to around
1.50 inches. Decent forcing with this system too, so feel good
with likely precip chances for now. Best chance for showers and a
few storms will be Sat evening into Sunday morning.
Saturday looks mainly dry during the day, so mild temperatures are
likely. May not have gone warm enough if the Sun is out for a
while given the 925 mb temps. Temps will be cooler on Sunday
behind the departing system.
Monday and Tuesday... Forecast confidence is medium:
models show a potent broad trough pushing through the area early
next week. Decent confidence that there will be showers at times
as impulses rotate through the trough, but not great agreement in
models with the timing and placement of these waves. Thus just
have some low end precip chances Mon and tue.
Temps will be near to a little above normal Monday ahead of the
main trough, with below normal temps likely Tue on the back side
of the system.
Aviation(09z tafs)... Areas of llws is possible through 12z this
morning via a swly 35 kt llj. A swly 45-50 kt LLJ will then
develop early this evening and exit SRN wi from 05z to 08z late
tnt. Thus llws is likely once again. Otherwise, winds will gust
around 25 kts from late this morning through the afternoon. Mostly
clear to partly cloudy skies will continue withVFR conditions,
although fog may form early Thu am in the wi river valley.
Marine... A small craft advisory is in effect today and tonight
for breezy sswly winds and increasing wave heights. Waves of 3-6
feet is forecast north of port washington with 2-4 feet from port
washington to winthrop harbor il.

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.
