Short term
Today and tonight... Forecast confidence is high.

A closed mid level low will continue to drift south from
minnesota into iowa today. This is part of a very large trough
system that extends up to james bay, canada. Temps aloft are quite
cold in the core of the low, down to -22c. At the surface, a low
pressure center will drift across southern wisconsin with
dewpoints in the 50sf. The weak convergence associated with the
low, coupled with the steep lapse rates due to the moist low
levels and cold temps aloft will lead to scattered showers and
isolated thunderstorms. Short wave perturbations rotating around
the upper low will help to encourage precip development. The rain
should focus best along the weak low level trough axis during
peak heat this afternoon where convergence will be maximized. This
could lead to some localized heavy rain. That axis should be
centered right over the middle of southern wisconsin. Given the
cold temps aloft, some small hail might fall out of out an over
productive shower/storm. No severe weather is expected today. The
activity will continue into tonight, but will begin to taper off
with the diminishing diurnal trends.

Long term
Wednesday and Thursday... Forecast confidence is medium to high:
the upper level low will continue to move slowly through the area
on Wednesday. This will keep shower chances going across southern
wisconsin. Below normal temps will continue with the precip
chances and mostly cloudy skies.

Should see a break in the precip on Thursday as the low pulls
away. Still looks like there should be a decent amount of
sunshine. High temps are expected to be back near normal, except
for cooler conditions near lake michigan.

Friday through memorial day... Forecast confidence is medium:
multiple shortwaves are expected to move through the area Friday
through memorial day. This will bring a daily chance for showers
and storms. No day looks like a washout through this upcoming
holiday weekend, but unfortunately no day looks completely dry
either. On a more positive note, there will probably be some
sunshine at times and temperatures are expected to remain around
normal values for late may.

Aviation(06z tafs)
We should see a lull in the shower activity early this morning.

But, this will pick back up by mid to late morning and continue
into tonight. A few thunderstorms are possible this afternoon and
evening, no severe weather is expected. Low pressure slowly
approaching from the west resulting in diminishing winds with high
low level rh lingering over southern wi. Seeing some increase in
sct-bkn MVFR clouds across southern wi so expect this trend to
continue as low edges closer during the late night into Tuesday
morning.

Marine
Low pressure developing and moving by to the south of lake
michigan will bring persistent northeast winds that will likely
build large waves resulting in small craft advisory conditions
Wednesday through Wednesday night.

Mkx watches/warnings/advisories
Wi... None.

Lm... None.

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.
