area forecast discussion... Updated
national weather service milwaukee sullivan wi
546 am cst Fri feb 22 2019

Update
The forecast is on track for the upcoming day.

Aviation(12z tafs)
Vfr conditions and light winds are expected through today under
high pressure. Mid level clouds will move through the forecast
early this morning, with mostly sunny skies then into the
afternoon. Will eventually see lower ceilings visibilites later
tonight as low pressure and precip head for the area. Mixed
precipitation is likely by late tonight, with a pretty good chance
for freezing rain most places by daybreak Saturday.

Prev discussion (issued 438 am cst Fri feb 22 2019)
short term...

today and tonight... Forecast confidence is high:
scattered mid to high level clouds will be possible into early
morning... But otherwise high pressure should bring plenty of
sunshine today. Temps will be near normal.

Strengthening low pressure will approach the area tonight,
bringing a mix of precipitation later in the night. Precip may
start off as snow, especially in areas northwest of madison. A
warm layer aloft will move in quickly though, with precip quickly
changing to freezing rain. There are sizable differences among
models with how much precip will arrive with this first round of
forcing. Some of the more aggressive models would suggest more
icing by daybreak than in the current forecast, but either way,
icing is expected to occur later tonight. Best chance of a quick
glaze of ice by early morning will be from the madison area
southwestward.

Saturday through Sunday night... Forecast confidence is medium.

Cyclogenesis will ensue over the tx ok panhandles Fri nt as a
strong shortwave trough approaches from the desert sw. The
deepening low will track to SE ia by 00z sun. Well ahead of the
low, a sly 30-40 kt LLJ and associated warm, moist advection and
frontogenesis will shift ewd across the region Sat am. Fairly
strong lift and steepening mid level lapse rates will lead to a
large area of moderate pcpn moving east across SRN wi. A strong
warm layer aloft of 2-6c will move nwd into SRN wi by late Sat am.

Initial pcpn chances will be mixed, but transitioning to freezing
rain as the column becomes saturated and relatively warm aloft.

Some models produce relatively heavy QPF totals but looks
overdone. Went with a blend of QPF which gives 0.25-0.45 over
south central wi and .15-.30 over east central and SE wi. Ice
accums are .10-.25 inches with lesser amounts toward central wi.

Sfc temps will warm above freezing over all of S wi by noon with
areas of light rain expected the remainder of the day. A winter wx
advisory has been issued for Sat am.

The 994 mb low over SE ia at 00z Sun will then track to the nrn
end of lake mi by 12z Sun and deepen to 979 mb. Widespread
moderate rainfall will arrive Sat eve on the nose of a strong llj,
and strong upper level divergence via PVA and warm advection at
the jet level. Strong cold advection will then ensue from west to
east after midnight. Much of the pcpn will move out before
changing to snow so only an inch or less is forecast toward
central wi. The occluded low will continue to deepen as it moves
into ontario on sun. A strong pressure gradient and well mixed
atmosphere should be a slam dunk for a wind advisory with wly wind
gusts of 45-55 mph. Higher wind gusts cannot be ruled out and
will depend on the details of the cyclogenesis and pressure
gradient. A high wind watch may eventually be needed for Sunday
into Sunday evening.

In addition to the winter weather and high winds, minor river
flooding and lowland flooding will be possible due 0.5-1.0 inches
of rain along with several inches of snow melt. Ice jams will be
possible.

Long term... Monday through Thursday... Forecast confidence is low.

The ECMWF drops another reinforcing upper trough and cold temps
into the NRN great lakes and SRN canada for mon-wed while the gfs
is weaker and farther north with this feature. Thus, the gfs
produces more warm advection and frontogenesis with chances of
light snow for this period. Overall, below normal temps are
expected with chances of light snow mon-wed. High pressure and dry
for thu.

Aviation(09z tafs)...

vfr conditions and light winds are expected through today under
high pressure. Will eventually see lower ceilings visibilites
Friday night as low pressure and precip head for the area. Mixed
precipitation is likely by late tonight, with a pretty good chance
for freezing rain most places by daybreak Saturday.

Marine...

kept the gale watch timing as is for now for late Sat night
through Sunday night. Might have to consider an upgrade to a
storm watch warning given gusts to 50 knots
possible... Particularly for the open waters. Less of a chance for
storm force gusts across the nearshore waters... Though not out of
the question. Heavy freezing spray will be also possible Sunday
night into Monday. The highest waves through this event will be
across the eastern half of the lake in ice free areas.

Lighter winds will return for early next week.
