.SHORT TERM...
(Issued 341 AM CDT Sun Jun 26 2022)

Today through Monday night:

The light winds, mostly clear skies and high dewpoints earlier
this morning has allowed some dense fog to develop. More
widespread dense fog will be found across low lying and rural
areas. As the westerly winds behind to increase out ahead of an
approaching cold front this morning, the fog will begin to
dissipate. Winds will shift to northerly behind the frontal
boundary later this morning and become gusty.

High pressure will gradually move into the Great Lakes Region
tonight. As high pressure moves in the pressure gradient will
relax and the winds will weaken. Dry conditions will persist
through Monday as the high moves overhead then begins to exit
Monday night. High temperatures in the low to mid 70s and
overnight lows in the 50s are expected through Monday. Once the
winds calm down, ideal nights for bonfires :).

.LONG TERM...
(Issued 341 AM CDT Sun Jun 26 2022)

Tuesday through Saturday:

Winds will shift to southerly behind the exiting high pressure
system Monday night into Tuesday. With the return of southerly
winds, there will be a return of warm, moist air advection into
the state. Temperatures will return to the 80s on Tuesday ahead of
an approaching frontal boundary. As the frontal boundary moves
through the state Tuesday, there will be a chance for some showers
and storms during the afternoon and evening hours. There is still
some uncertainty in the timing of the frontal passage and the
aerial coverage of rain.

With the upper level steering pattern becoming more zonal for the
the middle and end of the week there is expected to be a few waves
that move through the flow. Warm air advection is expected to ramp
up Wednesday into Thursday. There will be a chance for additional
showers and storms Thursday into Thursday night. With the more
zonal flow there is some uncertainty in the timing of the wave
and associated surface low, so will have to keep an eye on the
rain potential for the end of the work week. Otherwise guidance
suggests high pressure returning for the weekend to keep
conditions pretty quite across the Great Lakes Region.

.AVIATION...
(Issued 953 AM CDT Sun Jun 26 2022)

VFR conditions are expected today in a dry post-frontal air mass.
We could have some cu develop, and there are some hints of cu
already developing over northern WI, but do think that if any
ceilings do form in southern WI, they`ll remain in VFR. Biggest
aviation concern today will be the winds, which will be out of the
northwest and will gust to between 25 and 30 knots this morning
and into the afternoon before subsiding this evening.

.MARINE...
(Issued 341 AM CDT Sun Jun 26 2022)

Southerly winds across the lake early this morning will shift to
northwesterly behind the passage of a cold front. Higher dewpoints
and light winds over the nearshore zones this morning has allowed
some dense fog to develop for areas north of Port Washington. As
winds increase behind the cold front, the fog will mix out.

A tighter pressure gradient will set up across the Great Lakes
Region as high pressure approaches Wisconsin today. The
northwesterly winds will be gusty across the open waters and
nearshore zones. Thus a Small Craft Advisory is in effect for the
nearshore waters. Gale Conditions are not expected. High pressure
will move overhead late tonight into Monday cause the
northwesterly winds to decrease then shift to southerly on the
back side of the high.
