.PREV DISCUSSION... (Issued 955 PM CDT Sat May 16 2020)

UPDATE...High based light showers have begun to move into far
srn WI. This will continue over the next few hours, with the
heavier rain not expected until after 07Z. Otherwise, the forecast
is on track for tnt-Sun.

MARINE...Low pressure of 29.7 inches will form over Iowa tonight,
and move east across the far southern portion of Lake Michigan
tomorrow night, while deepening to 29.6 inches. The low will reach
northwestern Ohio by Monday afternoon. Gusty east to northeast
winds are expected along and north of the low Sunday and Sunday
night, especially over the northern portions of the lake. Winds
then turn northeasterly Sunday night into Monday as the low
progresses east. Gales will be possible over the northern half of
the lake Sunday night through Monday, therefore a Gale Watch is in
effect. A Small Craft Advisory is in effect from Sheboygan to
Winthrop Harbor from 09Z Sun until 18Z Tue.

PREV DISCUSSION... (Issued 751 PM CDT Sat May 16 2020)

UPDATE...Water vapor shows a couple strong shortwave troughs
pumping moisture from the Lower MS River Valley to the Upper MS
River Valley this evening. The strong shortwave trough over NE
will slowly move ewd across IA and nrn IL through Sun nt, with a
gradual deepening sfc low to reach far nrn IN by 12Z Mon. The big
surge of low to mid level thetae advection and frontogenesis will
occur late tnt into early Sun afternoon. A dry slot will then
follow for late afternoon into the evening. Impressive PWs of 1.5
inches or 175 percent of normal are expected over se WI for Sun,
while QPF probs for 2+ inches are 50-70 percent over far ern WI.
Overall mdt rainfall rates will prevail for this system, but with
some periods of heavy rainfall rates. Some thunder will be
embedded at times, but overall the flash flood threat would be
low. At least some minor river flooding and lowland flooding can
be expected with this system with some potential for mdt river
flooding.

PREV DISCUSSION... (Issued 300 PM CDT Sat May 16 2020)

SHORT TERM...

Tonight through Tomorrow Night...Forecast Confidence Medium...

Surface troughing is beginning to take shape across the central
Plains this afternoon, ahead of a shortwave trough over the Black
Hills. A closed surface low will form over Iowa tonight, which
will slowly move east across far northern Illinois tomorrow.
Expansive warm advection ahead of this feature is already
generating showers and thunderstorms across Missouri and Illinois,
and this activity will expand in coverage as it moves north
tonight. Expect showers and a few thunderstorms to overspread the
region from the south and southwest late this evening, continuing
into the overnight hours. East winds will also increase as the
surface low starts to approach later tonight.

Widespread rain and some thunderstorms are expected through the
day on Sunday, as the low moves through the region, and an
occluding frontal boundary moves along the state line region.
Thunder chances will be highest along and south of I-94, where
instability will be highest. Will need to watch for somewhat more
widespread convection in the vicinity of the front, along with an
associated threat for heavy rain. At this time, the heaviest rain
is expected to fall southeast of a line from Sheboygan to
Janesville, though ultimate amounts will depend on the exact track
of thunderstorms. 1 to up to 3 inches of rain is possible, though
the heavier amounts should be relatively localized. Even with
recent rains, overall soil conditions are on the dry side, with
plenty of runoff capacity in most area rivers. Thus, while some
localized minor flooding is possible (i.e., urban and small stream
runoff), don't think we're looking at a significant hydro event,
so no Flood Watch is planned at this time.

Temperatures tomorrow will be cool, especially closer to Lake
Michigan given the onshore flow. Low to mid 50s are expected for
most, though areas right along the state line might crack 60,
depending on where exactly the front sets up.

The low will continue to very slowly push east-southeast tomorrow
night into Monday, with a mid level dry slot pushing into the area
by late tomorrow. This will likely cutoff a lot of the heavier and
more widespread rain, but drizzle and occasional showers will
persist.

As the low starts to move east later tomorrow, northeast winds
will become gusty over most of the area. This onshore flow will
result in a threat for minor lakeshore flooding along the Lake
Michigan shoreline tomorrow night into Monday.

Monday and Monday Night...Forecast Confidence Medium...

Speaking of Monday, the overall progression of the system has
trended slower, so it looks a decent amount of cloud and shower
activity will stick around through the day Monday and into Monday
night. Brisk onshore flow will keep temperatures close to the lake
in the upper 40s and low 50s. Readings should be around 60 from
Madison westward, where a few peaks of sun might try to mix in
late in the day.

LONG TERM...

Tuesday through Saturday...Forecast Confidence is Moderate

A rather broad 500mb cutoff low looks to linger for much of the extended
period before finally flattening back into the flow aloft over eastern
Canada and getting kicked off toward the NE Atlantic Coast by next weekend.
Luckily, higher 500mb heights and warmer temperatures will arc northeastward
around this cutoff low and keep most of Wisconsin with seasonable temperatures
throughout the week. The only exception to this may be lakeshore locales as
while this low’s influence is sitting off to the southeast this week, E and NE
flow is predominantly expected. This should drive wind flow from off of Lake
Michigan and keep lake shore locales cooler. We should remain mostly dry and
sunny this week after Monday as well, as a sfc high pressure ridge will extend
westward into our area from the east coast for much of this week.

As the cutoff low exits late in the week, we could see temperatures become
quite warm as a upper level ridge builds in from the west.

AVIATION(21Z TAF Update)...

VFR will prevail this afternoon into this evening. Showers and a
few thunderstorms will begin to overspread the area late tonight,
along with MVFR and then IFR ceilings and visibility. IFR is
expected to prevail through the day on Sunday, with widespread
showers and thunderstorms through most of the day.

Winds will be easterly through the period, with gusts increasing
tonight as low pressure approaches from the west.

MARINE...

East winds will increase across the southern portion of the lake
and the nearshore waters this afternoon into tonight. This will
result in building waves over the nearshore, and a Small Craft
Advisory is now in effect starting late tonight. This will
continue through mid day Tuesday.

Winds will become northeasterly by late tomorrow as the low passes
over the southern portion of the lake. A period of gales is
possible over the northern portion of the lake late tomorrow night
into Monday, and a Gale Watch is in effect. These higher winds
will also result in building waves over the western portion of
Lake Michigan, which will pose a risk for lakeshore flooding
tomorrow night into Monday.

The higher winds will diminish Monday, but elevated waves will
persist into at least Tuesday, along with breezy northeast winds.
Expect winds to gradually diminish heading into the latter
portion of the week, as high pressure builds into the area.
