forecast discussion for routine afternoon forecast issuance

Short term Tonight and Tuesday
issued at 323 pm cdt Mon may 29 2017
a cold front that was in eastern wisconsin moved out of the state
this morning.

The 00z sounding at grb was pretty much dry adiabatic above a
surface based inversion that topped out around 950 mb. There were
a few showers early in the morning and they rapidly increased in
coverage once temperatures warmed up a bit. Surface based cape
increased throughout the morning, reaching values in excess of
800 j kg in north central wisconsin by midday.

Expect showers and isolated thunder to diminish during the evening
and overnight hours due to the loss of daytime heating. Another
mid level short wave trough will be passing through the area on
Tuesday, so expect chances for showers to increase during the day.

It looks to be cooler on Tuesday than today. With highs generally
ranging from the lower 50s to the lower 60s.

Long term Tuesday night through Monday
issued at 323 pm cdt Mon may 29 2017
the models agree that northwest upper flow will continue
through Thursday night or Friday. Significant differences begin
Friday night and Saturday when the ECMWF and especially the canadian
model forecast a closed low over minnesota while the GFS just has
the sharp trough moving through. The ECMWF and canadian models
would suggest cool and rainy days Saturday and Sunday while the
gfs would be would just have a few showers. Seeing that there have
been a lot of closed lows this spring would not discount the
canadian and ECMWF solution.

The forecast offices in the central part of the united states use
a blended model forecast for the 3 to 7 day period, so the current
forecast for Saturday and Sunday is drier than it should be if
the closed low does form and move across wisconsin.

Temperatures will start off slightly cooler than normal Tuesday
night and Wednesday, and then warm a few degrees above normal for
Thursday and Friday with dry air allowing for good diurnal
ranges. It will be cooler than normal if Saturday and Sunday turn
out to be rainy, otherwise near normal.

Aviation For 18z TAF issuance
issued at 104 pm cdt Mon may 29 2017
a cold front pushed east of wisconsin today and showers were
scattered across the area early this afternoon and ceilings were a
mix ofVFR and MVFR. Lightning was not indicating any thunder as
of 1730z, but surface based CAPE was in excess of 800 j kg in
north central and parts of northeast wisconsin so would expect
thunderstorms to develop. Unsure of the when where for storms so
have not included them in tafs. Thunderstorms may reduce ceilings
and or visibility to ifr.

Expect MVFR ceilings across central and north central wisconsin
late tonight through Tuesday morning.

Marine
Issued at 323 pm cdt Mon may 29 2017
west winds with gusts around 25 knots this afternoon will
diminish during the evening and overnight hours.

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.
