Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1126 AM CST Mon Jan 21 2019

.UPDATE...Immediate concern is enhanced lake effect snow band just
offshore, moving NNW to eastern Ozaukee and Sheboygan counties.
NAM indicating enhanced low level omega and convergence lingering
in eastern Sheboygan county into the early evening as low level
winds from the SSE increase, enhancing the low level convergence.
Bumped up pops and snowfall in eastern Sheboygan county, and could
potentially get 1-3 inches into the evening in this area. Will
watch closely and may need to issue quick Advisory as the snow may
interfere with evening commute.

&&

.AVIATION(18Z TAFS)...Lower ceilings and vsbys will accompany lake
effect snow showers in eastern areas through the afternoon, but a
general diminishing trend is expected from south to north. Lower
ceilings and vsbys will return later Tuesday as snow and a mixture
of precipitation spreads into southern WI. There may be a period
of Low level wind shear later tonight into Tuesday as well.

&&

.PREV DISCUSSION... (Issued 942 AM CST Mon Jan 21 2019)

UPDATE...

Shifting low level winds to the southeast and delta-T around 17C
will continue to generate scattered to numerous snow showers over
the lakeshore areas through the day. Fortunately, the low level
convergence looks weaker, but the cloud bearing layer is firmly
entrenched in the dendritic growth zone. Therefore, bumped up snow
totals to one half inch to one inch, but could have locally
higher amounts of 1 to 3 inches right at the shore. No changes to
Tuesday event.

MBK

MARINE...

Nearshore Waters...

Issued a Small Craft Advisory from 23Z today until 12Z Wednesday
for the nearshore waters of Lake Michigan. South winds will
increase by early this evening and continue into Tuesday, with
gusts of 25 to 30 knots at times. Waves will build to 3 to 5 feet
by early this evening, and 5 to 9 feet later tonight into Tuesday
evening. The winds should weaken somewhat Tuesday night, with
waves subsiding later Tuesday night as well. Freezing spray is
also expected into Tuesday.

Open Waters...

Considering a Gale Warning for the southern two thirds of the open
waters of Lake Michigan. South gusts to 30 knots are expected
tonight into Tuesday night/Wednesday morning. There is some
potential for 35 knot gales to occur, mainly over the southern two
thirds of the lake, later tonight into Tuesday evening.

Also considering a Heavy Freezing Spray Warning for tonight into
Tuesday, though conditions may be too borderline. Freezing spray
is expected into Tuesday, just not sure if it will be heavy enough
for a headline.

Will make decisions on these headlines for the afternoon issuance
of the marine forecasts.

Some gusts to 30 knots may occur later Tuesday night into
Wednesday as well, as winds shift to the northwest.

PREV DISCUSSION... (Issued 514 AM CST Mon Jan 21 2019)

UPDATE...Lake effect band slowed the westward push towards shore
but still expecting a trend onto portions of the shore this
morning. Adjusted some pops a bit. Otherwise bitterly cold temps
in place with some inland areas well into the teens/low 20s below
zero.

PC

AVIATION(12Z TAFS)...Watching lake effect band offshore as it
slowed its westward push since last update. Still expecting a few
snow showers to eventually work onshore this morning with minor
accums. Otherwise some MVFR cigs will drift inland for a time
today before southeast winds start to carry these clouds north of
the area. Mid and high clouds increase today into this evening. A
small chance of light snow will be in place this evening with the
waa regime. Otherwise expecting dry conditions. Snow will develop
Tuesday with widespread IFR conditions likely with some LIFR
potential as well Tuesday afternoon/evening.

PC

PREV DISCUSSION... (Issued 323 AM CST Mon Jan 21 2019)

SHORT TERM...
Today - Confidence...Medium
Main story early on is the bitterly cold temps. Overnight
readings tanked with clear skies, light winds and snow cover.
Many locales seeing double digit negative readings to start the
day. The other focus is lakeside with band of lake effect snow
showers trending westward from offshore. Have bumped up some pops
with some isolated accums of an inch or less. As traj shift
around to being more onshore some of these lake clouds will likely
shift westward and then get carried northward as low level flow
becomes more sse throughout the day. Otherwise plenty of mid/high
clouds upstream heading this way ahead of our next storm system.
Developing waa will be offset by very cold start and existing lake
clouds and increase in system clouds throughout the day. So will
steer towards colder guid numbers.

Tonight - Confidence...Medium
Developing waa regime ahead of the low likely to set up. Models
have been hinting at the potential of a band of a little light
snow or flurries with this forcing. Will have some small pops for
this. Otherwise with clouds and a a sustained southerly wind flow
it will be a much milder night.

Tuesday into Wednesday - Confidence...Medium to High
The main story precipitation-wise is with the system that moves
through the region Tuesday/Wednesday.

A mid-level trough currently in Nevada will propagate east-
southeast into Central Plains today/tomorrow with a briefly closed
off vort max developing Tuesday morning in Nebraska/Kansas. This
deep trough will lead to some very strong/deep lift ahead of it as
it approaches southern Wisconsin Tuesday. In the lower levels, an
850mb closed low develops in NE/KS as well late Monday night/early
Tuesday morning. This 850mb trough will become elongated into
Tuesday, but will still provide some very strong low level flow
out of the Gulf to provide this system will ample moisture to work
with. Down at the surface, a deep low is expected to develop in NE
Colorado Monday night and then track through northern Kansas,
southern Iowa, NW Illinois, and then southeast Wisconsin Tuesday
evening.

There are some differing opinions between the guidance on the
details of this event, which is typical at this range. First, the
NAM has been a consistent, low-end QPF outlier for the past few
runs with this event due to the trough not being as negatively
tilted as the GFS/ECMWF show. The ECMWF is on the other side of
this and brings across a much more amplified/closed 500/850mb
trough and a deeper/slower surface low. In between these two is
the GFS, which is the path we chose to follow at the moment. WPC's
preferred blend for this system is currently the 00z UKMET/GEM,
which doesn't appear to be too far off from what the GFS offers up
in our region.

Digging into the details with this system, there are a lot of
positives in terms of the potential for heavy snowfall rates. Of
note is the deep forcing due to the surface to mid level trough
and high moisture availability. To go along with this, there
appears to be some strong low level (surface-850mb) frontogenesis
with some negative EPV just above that circulation Tuesday
afternoon northeast of the surface-850mb low. So, am expecting
some banded precipitation to occur with this event, particularly
Tuesday afternoon/evening.

The negatives with this event are the low snow-liquid ratios
which will likely be in the 8-1 to 12-1 range with the higher
ratios occurring the further northwest you go. Also, there is the
issue with a warm front/nose moving into southeast Wisconsin which
could briefly turn the snow over to rain for a period when the
heaviest precipitation should be falling. Also, winds do not
appear to be very strong when the heaviest snow falls, but they do
pick up a bit overnight Tuesday into early Wednesday.

So, this left us with a decision on what to do with a potential
winter storm watch. We have a concern that there will be an area
that sees some heavy snowfall rates Tuesday afternoon/evening but
there is still some uncertainty for where that band would be. Due
to this, we decided to match up with ARX and DVN and put out a
watch in the area that we think has the highest chance of seeing
the heavy snowfall rates and the least likely chance of having a
change over to rain. This watch will run from southwest Wisconsin
through east central Wisconsin and go from Tuesday morning through
Wednesday morning.  There is the potential that some/all of the
watch area transitions to a winter weather advisory, particularly
the southern tier of counties, which if the low tracks a bit
further north could end up in the mix. Also, for simplicity, did
the watch for the same time for the whole area but should see the
snow develop first in southwest WI and work its way eastward. Will
let those details come out with any upgrade to a warning/advisory.

LONG TERM...
Thursday into Sunday - Confidence...Medium to High
The next story will be on the cold air progged to push down into
the region Thursday as an arctic front pushes through. Likely will
be doing some wind chill advisories with wind chills getting below
-20F. Beyond that, there are a few northwest flow type systems
 would could briefly 'warm' temps up and bring some light snow
 along with it. Didn't focus much on this period with the pending
 snow Tuesday/early Wednesday.

AVIATION(09Z TAFS)...Localized IFR conditions possible closer to
the lake this morning as lake effect snow showers move onshore.
Expecting minor accums of mainly half an inch or less. Otherwise
some MVFR cigs will drift inland for a time today before
southeast winds start to carry these clouds north of the area. Mid
and high clouds increase today into this evening. A small chance
of light snow will be in place this evening with the waa regime.
Otherwise expecting dry conditions. Snow will develop Tuesday with
widespread IFR conditions likely with some LIFR potential as well
Tuesday afternoon/evening.

MARINE...Still likely some higher wave action to account for so
will let ongoing small craft expire naturally at 10z. Another
small craft headline will be needed starting tonight. This is due
to tightening pressure gradient ahead of next low pressure
system. This will kick in the south/southeast winds and lead to
some higher wave generation.
