Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
159 PM CDT Mon Apr 3 2017

.SHORT TERM...

.TONIGHT and TUESDAY...Forecast confidence is high.

The dry slot over southern WI will erode this afternoon as more
showers push into the region with low pressure lifting north toward
the region. There is still plenty of moisture around with models
showing PWs of almost 1 inch tonight. The low will move across
central IL and into MI tonight bringing another round of rain
showers late this afternoon through tonight. Southern WI will be
under cyclonic flow with the vertically stacked mid level wave. As
the low pulls away overnight, another shortwave drops through
providing additional forcing for showers early Tuesday morning.

Northwest winds behind this system will bring drier air on Tuesday
and will start to scour out the clouds during the afternoon toward
central WI.

Tuesday Night through Thursday...Forecast Confidence...Medium

A strong mid/upper trough moves out of the Rockies onto the
Plains Tuesday night. The north and south branch of the jet phase
as a strong trough/upper low move across the upper Ohio Valley.

The models are in fairly good agreement on the track of the
evolving surface low, across southern and central illinois and the
upper Ohio Valley. The NAM, GFS and GEM all have the maximum
precipitation band just to the south across northern Illinois and
Lower michigan.

The models are keeping the colder solution Wednesday and
Wednesday Night as the system cuts off. The colder air working in
on the back side, along with dynamic cooling, looks to be cold
enough for snow mixing in Wednesday and Wednesday night and even
changing to all snow. The only limiting factor is the air in the
lower boundary layer that is above 0 Celsius.  850 temperatures
around minus 2.5 Celsius across most of southern Wisconsin
Wednesday afternoon, 1000 to 500 mb thickness of 540 over
Kenosha. Expect some areas to receive 1 to 2 inches of snow.
Concern is if the max precipitation band shifts a little farther
north, snow amounts would be higher. This is reflected with the
experimental snow graphics Max potential on the winter section on
our website, which is around 5 inches.

Northeast surface winds become strong Wednesday in the strong
pressure gradient from the surface low approaching northern
Indiana.

The GFS/GEM and NAM are slower than the 00Z ECMWF in moving the
low to the east, with lingering precipitation into Thursday
afternoon far east areas. The ECMWF is quicker in ending the
precipitation and building the surface high into the Upper
Mississippi Valley.

.LONG TERM...

Friday through Sunday...Forecast Confidence...Medium

The large upper trough over the Eastern great lakes moves east as
an upper ridge moves exits the plains and reaches Wisconsin
saturday. By Sunday the next trough is entering the plains, with
a southwest flow across southern Wisconsin.

A ridge of high pressure should be over Wisconsin Friday evening
with warm air advection beginning Saturday into Sunday morning. A
weak trough approaches from the west later Sunday with a chance
of rain showers, especially on the ECMWF.

Sunday Night and Monday...Forecast Confidence...Medium

The GFS is quicker in taking an upper low into Minnesota Monday,
while the ECMWF has it still in the plains.

Both models have showers Sunday Night into Monday with a weak
cold front.

&&

.MARINE...

North winds tonight will become northwest Tuesday morning. Gusts
will reach small craft criteria during this time.

Another low pressure system passing by to the south will bring
strong north winds Wednesday night and Thursday. A Small Craft
Advisory will likely be needed but a Gale Warning is possible.

.MKX WATCHES/WARNINGS/ADVISORIES...
WI...None.
