HANSEN

What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Milwaukee, WI wrote its last area forecast discussion before this river flood warning went out at Mar 28, 8:52 PM CDT, 1 hour 56 minutes earlier.

Area forecast discussion, Mar 28, 8:52 PM CDT, 1 hour 56 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Milwaukee/Sullivan WI
852 PM CDT Sat Mar 28 2020

.UPDATE...

Severe storm potential thinking remains similar to previous
discussion update. Hail and wind are the biggest concerns at the
moment...but a lot of shear out there, so still watching for quick
spin-ups.

&&

.MARINE...

Fog will remain an issue across roughly the southern half of Lake
Michigan into tonight, before winds shift to the southwest and
bring in a cooler/drier airmass. Will keep the Small Craft
Advisory going until later tonight while winds ramp up. The Gale
Warning for the nearshore and southern half of the open waters
later tonight into Sunday evening still looks reasonable.

&&

.PREV DISCUSSION... (Issued 704 PM CDT Sat Mar 28 2020)

UPDATE...

Still watching the thunderstorm potential this evening. Best
chance to sneak some surface based instability into the area
remains in the southwest forecast area. This area will have the
higher chance for a tornado/wind threat in addition to a hail
threat, with hail being the bigger concern elsewhere. Storms will
struggle as they head farther east/northeast given the
cooler/stable airmass from the lake under east winds. Should see
storms reach the southwest by around 8 pm, exiting the northeast
by around midnight.

Fog will linger in the east likely until the storms sweep through
and winds become south to southwest early tonight.

AVIATION(00Z TAFS)...

Thunderstorms are expect to continue to develop regionally this
evening, moving generally southwest to northeast through the
forecast area from roughly 01Z to 05Z. Best chance for severe
storms will be in the southwest forecast area and toward Illinois.

Fog and low clouds will hang on until the storms sweep through and
winds become south to southwest. May see a period of VFR late
evening into early tonight, with low clouds then moving back in
late tonight into Sunday morning as the surface low treks across
Wisconsin. Scattered showers, gusty winds, and low clouds are
then expected to persist through the day Sunday.

Still looks like a period of low level wind shear will be possible
this evening into early tonight...mainly from around 01Z to 07Z.

PREV DISCUSSION... (Issued 327 PM CDT Sat Mar 28 2020)

SHORT TERM...

Today through Tonight...Forecast Confidence is Medium to High.

Some 700mb warm air advection is responsible for the ongoing rain
over southern and central Wisconsin. This will continue to track
northeast though the rest of the afternoon. Fog is also impacting
portions of southeast Wisconsin with the lowest visibilites closer
to Lake Michigan. This fog will continue before clearing behind
the front tonight.

Once the first round clears, warm air advection will continue to
spark off showers and a few storms. Our main focus this evening
will be the arrival of the occluded front which will pop off some
surface based storms. This will be the focus of our severe storm
potential. Shear will be increasing this evening along with CAPE
around 500J/kg ahead of the front. In this high shear low CAPE
environment we could see a few strong to severe storms mainly
southwest and south of Madison. Main threat will be large hail
and strong winds. Can't rule out an isolated tornado looking at
helicity values on the hodograph in southwest Wisconsin. We'll be
keeping a close eye on the frontal boundaries over the next few
hours as they will impact the severe potential. At the moment it
looks like the warm front will stay just south of the area. Storms
are expected to clear the area between 10pm and midnight.

Sunday through Sunday Night...Forecast Confidence is High.

With the low pressure system over the state Sunday expect cloudy,
wet, and windy conditions through the day. Southwest winds will
gradually shift to the west and then northwest throughout the day.
Strongest winds are expected Sunday afternoon with gusts of
35-45mph. This could be an issue for any outdoor tents. As the
low pressure system shifts northeast expect winds to shift to the
northwest Sunday night and gradually become lighter. Rain showers
will also diminish with gradually clearing skies.

LONG TERM...

Monday through Wednesday...Forecast Confidence High...

North winds will slowly diminish on Monday as the surface low
continues east and high pressure builds into the area. Winds will
take on more of a northeasterly direction later in the day,
bringing cooler air in from Lake Michigan, and keeping readings
quite a bit cooler closer to the lake. Some lake effect cloud
cover is also possible. Highs are currently expected to reach the
low to mid 50s west, but only low to mid 40s closer to Lake
Michigan.

Relatively cool and quite conditions are expected for Tuesday and
most of Wednesday as well, with highs in the 40s and low 50s.

Wednesday Night into the Weekend...Forecast Confidence Low to
Medium...

The next chance for rain will develop later Wednesday as a surface
trough and frontal boundary move into the area. The front may
stall out just to our south Thursday, with rain chances continuing
into Friday. Still lots of uncertainty with timing and structure
with this system, so overall confidence is on the low side. Once
this system clears the area, northwest flow will keep temperatures
around or just a little below average heading into the weekend.

AVIATION(21Z TAFS)...

LIFR and IFR ceilings continue with LIFR and IFR visibilities
towards the lake. Will see some showers and a few thunderstorms
continue off/on this afternoon before our main round of storms
moves through 00Z-04Z this evening from west to east. Best chance
for any severe storms will be southwest and south of Madison with
large hail, strong winds, and maybe an isolated tornado. Once
storms clear expect ceilings and visibilities to increase to VFR.
Sunday morning MVFR ceilings return along with light rain showers.

MARINE...

Dense fog over the southern half of the lake will clear late
tonight as the front moves through. Behind the front southwest
winds will increase with gales expected Sunday morning and into
Sunday evening over the southern half of the lake. Winds will
shift to the west and then northwest Sunday night and gradually
become lighter as high pressure moves into the region.
