Area Forecast Discussion...UPDATED
National Weather Service Milwaukee/Sullivan WI
1148 PM CST Thu Feb 13 2020

.UPDATE...

Temperatures have dropped into the single digits below zero
across all but the lakeshore areas. Wind chill values are only a
little colder than the temps since winds are fairly light, but
any puff of wind will bring those values into more critical
levels. Thus, the Wind Chill Advisory is in effect.

&&

.AVIATION(06Z TAFS)...

VFR conditions with clear skies through Friday afternoon.
Southerly winds will begin increasing Friday evening and some high
clouds may start to stream in. Low level wind shear is a concern
for Friday night.

&&

.PREV DISCUSSION... (Issued 853 PM CST Thu Feb 13 2020)

UPDATE...

No change to the forecast for tonight.

MARINE...

Northerly winds and high waves will gradually weaken tonight.
Southwesterly gales will develop late Friday night and persist
through Saturday as low pressure of 29.2 inches moves from
northern Manitoba to Hudson Bay. A Gale Watch is in effect for all
of Lake Michigan. Much lighter winds will return for Sunday as
polar high pressure moves over Lake Michigan.

For the nearshore waters from Sheboygan to Winthrop Harbor, a Heavy
Freezing Spray Warning remains in effect until midnight.

PREV DISCUSSION... (Issued 606 PM CST Thu Feb 13 2020)

UPDATE...

No change to the forecast for tonight. Skies are clear, winds are
diminishing, and temperatures are dropping quickly.

AVIATION(00Z TAFS)...

VFR conditions with clear skies through Friday afternoon.
Southerly winds will begin increasing Friday evening and some high
clouds will start to stream in.

PREV DISCUSSION... (Issued 304 PM CST Thu Feb 13 2020)

SHORT TERM...

Tonight through Friday night...Forecast Confidence is High.

Nwly sfc winds will become light by early evening, while polar
high pressure over the nrn Great Plains will move to the MS River
Valley by 12Z Fri. Clear skies will prevail tnt-Fri with a good
radiational cooling setup for tnt. Thus 10 below to 15 below zero
temps still look good well inland from Lake MI with possibly 20
below zero in the WI River Valley. Sfc winds will become very
light over south central WI late tnt, with perhaps 5-10 mph of
wind toward east central and far ern WI. After coordinating with
surrounding NWS offices, will go with the Wind Chill Advisory from
8 pm tnt until 10 AM Fri. Overall ranges will be from 15 below to
25 below zero.

Swly winds and warm advection will begin Fri afternoon and
increase Fri nt as the polar high moves east and strong low
pressure tracks across srn Canada. Temps will warm through the
night.

LONG TERM...

Saturday through Sunday...Forecast Confidence is High.

A quick hitting system is expected Saturday as a front swings
through the area. There is some upper level divergence with the
jet at 250mb along with some positive vorticity advection that
will provide support for a light dusting of snow. Dry conditions
then return Saturday night and continue into Sunday. Gusty
southwest winds will help temperatures get into the mid 30s on
Saturday. Lighter winds are expected behind the front Saturday
night into Sunday.

Sunday Night through Thursday...Forecast Confidence is Medium.

Southwest flow at 850mb looks to develop Sunday night with warm
air advection over southern Wisconsin through Monday afternoon.
Additionally there will be added support at 500mb with some
positive vorticity advection Monday evening into Tuesday. With
these lifting mechanisms light snow will be possible Sunday night
into Tuesday morning and may mix or transition to rain Monday
afternoon. There still remains some uncertainty with the exact
timing and track of this system so expect a few more tweaks as we
head into next week. Dry conditions are expected for Wednesday
and Thursday as high pressure builds over the area.

AVIATION(21Z TAFS)...

VFR conditions and mostly clear skies tnt-Fri.

MARINE...

Brisk north winds and high waves will gradually weaken
into tonight. A ridge of high pressure around 30.5 inches will
move across Lake Michigan on Friday. Southwesterly gales will
then become possible late Friday night into Saturday as the high
moves away and low pressure of 29.2 inches moves from northern
Manitoba to Hudson Bay. A Gale Watch is in effect for all of Lake
Michigan. Much lighter winds will return for Sunday as polar high
pressure moves over Lake Michigan.

For the nearshore waters from Sheboygan to Winthrop Harbor, a
Small Craft Advisory remains in effect until 6 PM for lingering
high waves. A Heavy Freezing Spray Warning remains in effect until
midnight.
