tonight and memorial day... Forecast confidence is high:
still looks like a few showers and a storm or two are possible
this afternoon, mainly affecting the northeast half of the
forecast area per latest mesoscale models. The front and
associated line of precip is expected to exit the east by early
evening, with mostly clear skies and dry weather overnight.
Another shortwave is progged to slide through on memorial day,
bringing a chance for showers and a few storms. The best chance
will be in the late morning afternoon and it won't be a washout,
so looks like there should be plenty of opportunities to enjoy the
holiday. Temps will be within a couple degrees of normal, with
the warmest conditions in the east where some sunshine will hang
on the longest.
Tuesday through Wednesday... Forecast confidence is high.
The upper low will continue to spin over ontario the next couple
of days. Tuesday will basically be a repeat of Monday, with
scattered showers, a couple rumbles of thunder, and gusty west
winds. Best chance for showers will be during the afternoon hours
ahead of a shortwave trough swinging through the area.
High pressure will spread into the midwest on Wednesday. That
upper trough will be exiting eastern wi by early afternoon. Aside
from some cumulus clouds, it looks too dry for any precip.
Thursday through Friday... Forecast confidence is medium.
A thunderstorm complex is expected to roll through the plains
early Thursday and track across northern il Thu afternoon, right
as a warm front starts to push into southern wi. Timing and
location are subject to change, so there is a chance for showers
and thunderstorms Thu afternoon evening for our area. Preliminary
model soundings show very marginal instability.
It looks like a cold front moving down the lake will keep at least
southeast wi dry for Friday, but the convergence zone along the
front could help trigger a few showers and thunderstorms during
the afternoon in south central wi.
Saturday and beyond... Forecast confidence is low.
The weekend looks unsettled at times. There is still a lot of
uncertainty so stay tuned.
watching clouds and showers storms developing along a frontal
boundary that has moved into the western forecast area at this
time. Looks like the northeast half of the forecast area will be
the focus for any showers or storms that develop in this area.
This activity will exit the east by around 00z. Should see mainly

Quiet weather this evening and overnight will be followed by
another chance for showers later Monday morning into the

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.
