forecast discussion for routine afternoon forecast issuance

Short term Tonight and Sunday
issued at 224 pm cst Sat feb 23 2019
the main and only concern over the next 24 hours will be the major
late winter storm that is forecast to sweep across the region
tonight.

The 19z msas surface analysis showed the strengthening area of
low pressure situated over eastern ks. An inverted surface trough
extended north into western mn with a warm front extended eastward
to just north of the ohio valley. The first round of
snow freezing rain rain has exited the region and there was a lull
in the precipitation back into northeast ia. While patchy drizzle
or freezing drizzle may still occur this afternoon, it appears
that most areas will be dry through sunset.

The intensifying area of low pressure is forecast to quickly move
northeast from the central plains to southwest wi this evening and
reach central or eastern upper mi by daybreak. The lull in the
precipitation will end abruptly early this evening as lift
increases from the approaching low pressure and mid-level q-g
frontogenetical forcing increases with the associated negatively-
tilted shortwave trough. Precipitation type remains the biggest
headache, especially across central far northeast wi where a
wintry mix of freezing rain sleet snow to exist. North-central wi
to see mainly all snow tonight (locally heavy at times), while
east-central wi should see mainly rain this evening before the
rain becomes mixed with freezing rain and snow after midnight as
colder air gets pulled south behind the surface low. The main band
of precipitation appears to move through northeast wi between 03z
and 09z. Anticipate 8 to 12" of accumulation across north-central
wi tonight, while east-central wi may only see a dusting. It
should be noted that there may be minor flooding issues over east-
central wi where storm drains are clogged and the combination of
rain and melting snow may create some localized issues.

Light snow will continue into Sunday morning as the intense
surface low tracks into southeast ontario. Perhaps an additional
inch or two (2 to 4 for vilas county) of accumulation with storm
totals to range from less than an inch over east-central wi, to 12
to 16" over north-central wi. The bigger story for Sunday to be
very strong winds expected between the strong surface low and high
pressure over the northern plains. Look for sustained west to
northwest winds at 20 to 30 mph north, 25 to 35 mph south with
gusts of 40 to 50 mph by Sunday afternoon. Have issued a wind
advisory for counties that are expected to see an inch or less of
snow (practically east-central wi) and allow other current
headlines to incorporate the blowing snow treacherous travel
conditions. MAX temperatures of upper 20s central wi, lower to
middle 30s eastern wi to occur early in the morning with falling
temperatures for the rest of the day.

Long term Sunday night through Saturday
issued at 224 pm cst Sat feb 23 2019
gusty winds will continue Sunday evening as low pressure pulls
away from the region. Gusts over 40 mph are likely during much of
the evening hours across east-central wisconsin and the lakeshore,
before diminishing by midnight. Therefore will continue the wind
advisory for these areas.

Light snow will continue across north-central wisconsin along
with blowing snow across the entire area during the evening hours.

The winter weather advisory will continue for portions of north-
central wisconsin during the early evening hours to account for
the ongoing snow as well as the blowing and drifting. Temperatures
will also plummet Sunday night, falling to around 10 below across
north-central, the single digits below zero across central, and
around zero across east-central wisconsin and the fox valley. The
combination of gusty winds and the cold temperatures will cause
wind chill values to fall to 20 to 30 below zero, which could
necessitate the issuance of a wind chill advisory for much of the
region later Sunday night into Monday morning. The areas with the
coldest wind chills will be across central and north-central
wisconsin where temperatures are expected to be colder.

Highs on Monday will not recover much, as daytime highs only rise
to 5 to 10 degrees above zero during the afternoon. An even colder
night is in store Monday night as overnight lows sink to 10 to 15
below zero across central and north-central wisconsin, with lows
in the single digits below zero across east-central wisconsin and
the lakeshore. Despite the colder temperatures, winds will be
lighter than Sunday night. However wind chill values will still
fall to 15 to 25 below zero Monday night into Tuesday morning,
which may require another wind chill advisory, particularly across
central and north-central wisconsin.

Temperatures begin to moderate by Tuesday as a low pressure system
tracks through the western great lakes region. This low may bring
a few inches of light snow as it passes through Tuesday afternoon
through Wednesday morning as highs moderate into the upper teens
to lower 20s by Wednesday afternoon.

Another low pressure system is slated to track through the western
great lakes region late in the week and into the early part of
next weekend. Temperatures will continue to be below normal during
this stretch with a few inches of snow expected from this system.

Aviation For 18z TAF issuance
issued at 1210 pm cst Sat feb 23 2019
lull in the precipitation for this afternoon, however CIGS to
remain ifr MVFR with patchy drizzle or freezing drizzle.

An approaching winter storm will produce a large area of mixed
precipitation across the area tonight, with ceilings and
visibilities falling to ifr to local lifr in heavier snow. The
snow is forecast to taper off Sunday afternoon with a slow
improvement to MVFR conditions.

Strong west to northwest winds will produce considerable blowing
and drifting snow Sunday where considerable new snow falls. Have
kept llws wording in all TAF sites for tonight into Sunday
morning.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
