209 pm cdt Sun apr 22 2018

Short term
Tonight and Monday... Forecast confidence is high.

A 500 mb mid level low will remain well south of the area on
Monday, with weak ridging across southern wisconsin. The
influence of the surface high centered well east of the area will
keep things dry. Only a few high clouds.

Monday night through Tuesday night... Forecast confidence is
medium.

The 500 mb low moves slowly east northeast Monday night into
Tuesday, staying well southeast of the area. A few models bring a
hundredth of precipitation into the far southeast on the
periphery of the 500 mb low circulation. Kept a very low pop in
for now. The north edge of mid and even some low clouds may brush
the southeast.

Cold air advection occurs later Tuesday night on the backside of
the eastern u.S. Low. The models are in decent agreement with a
rather strong 500 mb shortwave trough moving southeast across
wisconsin Tuesday night.

The main question will be how moisture moves into the area ahead
of the trough. For now, have only a few north areas with low end
pops.

Long term
Wednesday through Sunday... Forecast confidence is medium.

A period of quiet weather looks in store for Wednesday into
Thursday morning, as high pressure passes through or just south of
the region.

Models then are indicating a cold front to move southeast through
the region Thursday or Thursday evening. They also bring a fairly
robust and deep 500 mb shortwave trough southeast through the
region. There is some moisture to work, along with steep low
level lapse rates. Continued blended model pops for Thursday into
Friday.

Quiet weather then returns Friday night into Sunday. Temperatures
should be a little below seasonal normals, moderating back to
normal Saturday and Sunday.

Aviation(18z tafs)

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.
