today and tonight... Forecast confidence is medium.

The rain is gradually diminishing from north to south as the low
level jet veers over northern il. I left the southern tier of
counties in the flash flood watch since it's still lightly raining
there. We heard that lafayette county is having a lot of issues
with flooding right now, but no specific information. We will know
more after daylight. We will be extending the flash flood warning
for that county in a later update.

The morning will be quiet and cloudy across southern wi. Drier air
will be spreading into the area as the day GOES on, although
lingering moisture in the low levels will lead more broken cloud
cover. The atmosphere is expected to be capped around 800 mb
today, so despite the 1000 j kg of cape, thunderstorms are going
to be hard to come by. Kept a slight chance going in southeast wi
this afternoon.

A robust shortwave trough upper low will track across lake
superior tonight. The vorticity advection and associated trough
sliding through central wi may trigger a few showers and storms
tonight north of i-94. There is a slight risk of severe with
steeper mid level lapse rates and 1000-1500 j kg cape. Hail would
be the main risk.

The warm and humid air will persist over the area, with highs in
the lower to mid 80s today and lows tonight in the upper 60s.

Sunday through Friday Forecast confidence is high.

Didn't focus too heavily on the extended given the ongoing flooding
concerns tonight. There is a small chance for a shower or storm on
Sunday as a weak cold front moves through. Thereafter, expect quiet
and dry weather on Monday and Tuesday, with high pressure in
control. Our next shot for showers and storms is on Tuesday night
into Wednesday morning as a cold front sweeps through. High pressure
returns into Thursday morning, with shower and thunderstorm chances
returning later Thursday into Friday. Look for slightly below normal
temperatures on Monday into Tuesday, trending towards normal
thereafter.

Aviation(06z tafs)
Showers and a few thunderstorms may affect eastern and far
southwestern portions of the area for the next few hours.

Otherwise, light winds are expected overnight. Low ceilings down
to 600 feet or so are expected into early this morning, before
rising above 3000 feet this afternoon. Visibility values should
drop down to 1 to 2 miles at times between 09z and 13z Saturday as
well, possibly lower in low lying areas. These should improve
above 6 miles by middle to late morning as well.

There are small chances for showers and thunderstorms this
afternoon into tonight across portions of the area. For now, left
mention out of tafs due to low confidence. Light north to
northeast winds are expected Saturday, with light west winds
Saturday night. There is some possibility of low ceilings and
visibilities with fog once again later tonight. For now, not
confident enough to go with lower values at this time.

Marine
Fog is possible through mid morning. North winds will increase
Sunday night and Monday but are expected to remain below small
craft levels.

Mkx watches warnings advisories

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.
