Area Forecast Discussion
National Weather Service Green Bay WI
350 PM CDT Wed Apr 13 2022

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Thursday
Issued at 350 PM CDT Wed Apr 13 2022

Lots going on in the short term forecast. Immediate focus is on
developing showers across southern and western WI and potential
for any thunderstorms this afternoon. Cooling temps will lead to
minor snow accumulations across the north tonight and again
tomorrow. The main story tomorrow will be the wind. Gusts of 35 to
45 mph has prompted a Wind Advisory for much of the area.

This afternoon...The main surface system remains back across the
ND/MN border, while a second low pressure has setup across
western Wisconsin. The warm front extending east from this low has
been a little farther south than initially anticipated today,
keeping temperatures and dew points cooler and the low clouds in
place. Over the past hour or two, the warm front has inched
northward into the southern forecast area, which is noted by the
wind direction and temperature differences at KOSH compared to
farther north. The main impact this has on today's weather is the
lack of instability and thunderstorm potential. Current
mesoanalysis shows barely any instability in WI, yet alone
northeast WI. There are a couple small areas of MUCAPES 200 to 400
J/kg across southern WI as of 19Z. CAMs vary on developing any
CAPE later this afternoon, with some backing down to 300 to 500
J/kg across east-central WI from about 4pm to 8pm. Will continue
to carry chance of thunderstorms across the Fox Valley and
northeast WI until around 03Z/10pm. SPC reduced this area to a
marginal risk (down from a slight earlier) as well. There could be
isolated strong storms which produce hail or brief, gusty winds.
But think overall severe threat is limited at this point.

Tonight...Attention then turns to the rain/snow potential tonight.
As the first low rotates north through WI this evening and
overnight expect light to moderate precipitation to develop. As
temperatures drop across northern and parts of central WI rain
will mix with and change to snow, leading to minor accumulations
by Thursday morning. Less than 1 inch of snow is expected across
north-central WI. Overall QPF (mainly from rain) will range from
quarter to half an inch in most places, allowing for some minor
ponding on roadways and continue to swell the slowly rising
rivers. Lows will range from the upper 20s in the Northwoods to
the lower 30s across east-central WI.

Thursday...There will be a lull in the precipitation through much
of the morning. As the upper low/main surface low track across
northwest WI this will provide enough lift to produce scattered
showers through the late morning and afternoon--primarily across
northern and central WI. Moisture is not considerably deep, so
expect scattered and light amounts. Ptype will mostly be snow by
this point as cooler air wraps around from the low. Additional
snow amounts will range from a dusting to half an inch across
north-central WI, with little to no accumulation elsewhere. Highs
Thursday will range from the middle 30s in the Northwoods to the
middle 40s in the Fox Valley.

.LONG TERM...Thursday Night Through Wednesday
Issued at 350 PM CDT Wed Apr 13 2022

Fairly progressive flow expected over much of the CONUS through
the period, sending several systems across the Great Lakes. Not
much warm air to push into the region, so looking like reaching
the 50s will be a struggle into early next week. Flow turns more
southerly toward the middle and end of next week, which should
allow temps to climb back toward normal.

Thursday night into Friday...vertically stacked low pressure will
continue to sit and spin and slowly meander northeast across
Ontario. This will keep a cool, cyclonic flow across the region.
Combined with embedded pieces of weak shortwave energy and
moisture wrapping around the low, still expect rain/snow shower
activity to continue at times across much of north central WI,
with a few flurries or sprinkles possible farther south/east. Will
not be impactful with only some slushy accumulation possible on
grassy surfaces. The left over boundary and baroclinic zone will
also be lurking to our south and could have some light precip
associated with it over the southern CWA, but this should push
southward during the day on Friday. Wind will decrease in the
evening as better mixing comes to an end, but gradient remains
tight through the night, so expect winds to remain gusting up to
30-35 mph. Friday will be less windy than Thursday, but gusts to
around 30 mph are still expected. It will be a cold April night,
with lows ranging from the teens and 20s over central and northern
WI to closer to the freezing mark near Lake Michigan. Friday will
be another cool day with well below normal temps. Highs only in
the 30s to lower 40s are expected, with wind chills in the teens
and 20s...brrrrr.

Rest of the long term...lingering sprinkles or flurries are
possible Friday night as the low slowly pushes into Quebec and
high pressure builds into the western Great Lakes. This high will
bring quiet weather and less wind to the area for the start of the
weekend. The next system will track across the northern Plains
this weekend and arrive in the Great Lakes by Monday morning. It
will spread a round of precip across the area Sunday night into
Monday morning. Temp profiles support mainly snow with some rain
mixing in over the south. Slushy accumulations are looking more
likely, especially over central and northern WI. Additional
rain/snow showers are expected on Monday as the upper trough
pushes through the area. Brief ridging builds in behind this
system with another system bringing more unsettled weather to the
area mid next week. No above normal temps are in sight, with no
sustained push of warm air through the middle of next week.

.AVIATION...for 18Z TAF Issuance
Issued at 1244 PM CDT Wed Apr 13 2022

A mix of mainly IFR/LIFR flying conditions are expected through
the rest of today and most of tonight. Occasional breaks in the
low clouds and good visibility will create brief windows of VFR
or MVFR conditions, but the general trend will be for cigs around
200 to 600 ft. Vsbys improved early this afternoon from the
morning fog, but expect vsbys to drop again once rain arrives
mid- afternoon. Thunderstorms are still possible from mid
afternoon to early evening (generally 3PM to 8PM CDT) and tailored
each TAF forecast to the most likely timing via TEMPO groups.
Outside of the thunderstorm window, rain showers will persist
through most of the night. Cigs and vsbys improve tomorrow morning
with the main impact becoming winds. Southwest gusts to 35 to 40
kts are possible.
