forecast discussion for routine afternoon forecast issuance

Short term Tonight and Tuesday
issued at 243 pm cdt Mon sep 25 2017
the main forecast focus to be on precipitation trends both tonight
and Tuesday as a slow-moving cold front shifts across the state.

The 19z msas surface analysis showed the cold front stretched from
roughly ironwood south-southwest to la crosse and then farther
southwest through central ia. All the showers thunderstorms have
been along and behind the frontal boundary with one cluster of
storms that will impact central wi by late afternoon. Temperatures
were once again unseasonably warm with record or near record high
temperatures over eastern wi.

The stalled synoptic pattern across the CONUS finally begins to
move starting tonight as the upper trough over the western conus
lifts northeastward toward the northern plains and helps shove the
cold front into central wi. Models also show a weak surface wave
lifting north along the frontal boundary tonight which would tend
to slow the front down or even briefly stall its eastward
progress. Deeper moisture and stronger forcing to remain behind
the front, thus highest pops will be placed across north-central
wi where the front should reach first. Eastern wi may see a stray
shower toward daybreak, but anticipate a mainly dry night. One
more mild night can be expected with min temperatures around 60
degrees north-central wi, lower to middle 60s east-central wi.

The upper trough is forecast to move from the northern plains
toward northern sections of the upper ms valley southwest ontario
on Tuesday and gradually weaken in the process. Meanwhile, the
slow-moving cold front edges farther east and should reach lake mi
by 00z Wednesday. The deeper moisture modest instability finally
overspreads the rest of northeast wi on Tuesday, therefore showers
should become more likely. Since forcing is weak, thunderstorms
should be scattered about, but no severe weather is anticipated.

Max temperatures will be noticeably cooler with readings around 70
degrees north-central, upper 70s to around 80 degrees east-central
wi.

Long term Tuesday night through Monday
issued at 243 pm cdt Mon sep 25 2017
cooler and less humid air will return to wisconsin
Wednesday night and continue through the end of the week, as upper
flow becomes northwest and a surface high drops south from
central canada into the great lakes. A shortwave trough moving
through the upper flow should produce enough upper support to
produce scattered showers and thunderstorms Thursday afternoon and
evening. Temperatures will be close to normal Thursday through
Saturday.

Warmer temperatures will return Sunday and Monday as heights rise
and winds become southerly as the large surface high moves east.

There should be some showers and thunderstorms Monday as upper
flow becomes southwest and a weak surface front approaches from
the west.

Aviation For 18z TAF issuance
issued at 1235 pm cdt Mon sep 25 2017
vfr conditions are expected to persist through this afternoon. As
a cold front slowly approaches the area over the next 24 hours,
there will be an increasing chance for showers and thunderstorms.

This is expected to begin late this afternoon across north-central
and parts of central wi with vsbys dropping down into the MVFR
category under any precipitation. These showers storms will
continue in scattered fashion tonight, mainly across central parts
of the state, while eastern sections remain dry. As the front
reaches central wi late tonight Tuesday morning, CIGS will quickly
drop into the ifr range and remain there through the rest of the
day. Scattered showers thunderstorms to also persist on Tuesday,
thus flying conditions will not be optimal across central or
north-central wi. Eastern sections of the state may not see rain
chances pick up until Tuesday afternoon as the front is a slow-
mover.

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.
