forecast discussion for routine afternoon forecast issuance

Short term Tonight and Tuesday
issued at 226 pm cdt Mon may 22 2017
the latest rap analysis and satellite/radar imagery show upper level
low pressure centered across lake superior, a compact shortwave
moving east over south dakota, and a surface trough positioned over
southern mn into nebraska. Scattered showers will continue to move
east from northwest wi into north-central and far NE wi for the rest
of the afternoon. Instability has been slow to build over central
and east-central wi so far today, but continue to see CU build up in
this area, and hi-res mesomodels continue to point towards some
showers developing. Any thunderstorms will most likely be isolated
given the lack of forcing and instability. More widespread shower
activity exists over sd with the compact vort max. As this
shortwave moves towards the area late tonight into Tuesday, rain
chances and trends will be the main forecast concerns.

Tonight... Upper troughing will continue to reside across the
northern great lakes, while the shortwave trough over eastern south
dakota moves into southwest wisconsin late in the night. A few
showers over far northern wi and also over east-central wi could
linger into the mid-evening hours. Once the lingering showers
diminish, should see a lull in the precip chances until the
shortwave over sd and associated surface low move into southwest
wisconsin late. Did slow the chances down somewhat based on the
latest model data. Low temps ranging from the upper 30s in the
north to near 50 over the southern fox valley.

Tuesday... The shortwave will swing northward across western
wisconsin, and will lay out a convergence zone just west of the fox
valley and bay of green bay. Though some showers will likely be
moving northeast across central wi at the start of the morning, this
convergent zone looks to be the focus for shower activity for the
rest of the day. Do not see much instability with clouds and precip
arriving in the morning, so left the mention of thunder out of the
forecast. Temps will be cooler in many spots, and range from the
upper 50s to low 60s across the region.

Long term Tuesday night through Monday
issued at 226 pm cdt Mon may 22 2017
precipitation trends are the main forecast concern.

An upper level trof and inverted surface trof will bring
showers to the entire region Tuesday night, and to the
southeast portion of the forecast area on Wednesday.

A weak ridge of high pressure will bring dry conditions
Wednesday night into Thursday evening, but small rain
chances will return as WAA develops late Thursday night
into Friday.

A series of weak short-wave trofs and associated cold fronts
will continue to bring periodic bouts of scattered showers
thunderstorms through the memorial day weekend, but the majority
of the period should be dry. Have sided more with ecmwf, as the
gfs has been exhibiting signs of convective feedback issues with
the weekend forecast over the last few days.

Below normal temperatures at the beginning of the period will
moderate to slightly above normal by Friday and Saturday, then
back to normal for the end of the holiday weekend.

Aviation For 18z TAF issuance
issued at 1146 am cdt Mon may 22 2017
weak disturbances will pass across wisconsin this afternoon,
which will result in scattered showers developing over the
north-central wi and also over east-central wi. An isolated
thunderstorm could also develop over east-central wi as well.

Ceilings will rise this evening once the disturbance departs, but
then looking at a weak low pressure system bringing showers to the
area from early Tuesday morning through the rest of the day.

Ceilings will gradually fall Tuesday morning as showers arrive.

Grb watches/warnings/advisories
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.
