What forecasters said that day
The local office's own words before this frost advisory 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 frost advisory went out at Sep 28, 2:42 AM CDT, 2 minutes earlier.
Area forecast discussion, Sep 28, 2:42 AM CDT, 2 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
242 AM CDT Fri Sep 28 2018
.DISCUSSION...
Today and tonight...Forecast confidence is high.
The surface cold front has pushed south of the border, but won't
move much farther south. Most of the shower activity will end for
while, with most areas dry through about mid morning. However, a
mid level short wave trough will swing through the area today,
helping to produce a post frontal narrow axis of h8-h7mb
frontogenesis. This will result in a similarly narrow band of
showers from late morning through mid afternoon that will impact
mainly our very southern counties. The NAM has been the farthest
north with this band, but has shifted south with the 00z Fri run.
Some of the guidance is keeping this band just south of Wisconsin,
so that's a possibility. Will keep the chances limited to the far
south, with the northern half of our forecast area likely dry
through the day.
Things clear out quickly by this evening. Cold air advection and
lower dew points will allow temps to fall into the lower and mid
30s. There are some wind concerns, meaning too much, especially
just above the shallow inversion. This would limit some of the
frost potential due to mixing, especially closer to Lake Michigan.
Saturday - Confidence...Medium
Chilly and frosty start to the day with high pressure in control.
The high shifts slowly east in the afternoon but the lingering
influence is expected to keep any precipitation to our south and
southwest. A weak return flow does set up but airmass likely to be
too dry to support precip. The 12z ECMWF and 00Z GEM bring very
light qpf into the far southern cwa during the afternoon but at
this point would prefer to side with the dry look of the 00z NAM/
GEMreg and GFS. Should at least see some increase in clouds as the
day wears on though.
Saturday night through Monday night - Confidence...Medium
Low pressure will move from the central Plains towards the lower
Lakes region later int he period. This low will ride along a
frontal boundary that will largely remain to our south. However,
the surface front may sneak into the far southern cwa for a time
on Monday. Decent 850 waa/moist advection gets underway Saturday
night into Sunday with precipitation becoming fairly widespread.
Elevated cape is pretty modest but there is an uptick later Sunday
into Monday so retaining the thunder mention seems reasonable at
this point. Enhanced vertical motion may result from the influence
of a right rear quad of upper level jet. The passing low will
pull that front through the area as a cold front Monday evening
gradually bringing an end to the rain chances for the time being.
PW's rise to 1.5 or higher getting into Monday so some decent rain
potential within the tighter 850/925 baroclinicity and then as
the front pushes through Monday evening.
Tuesday - Confidence...Low to Medium
May see some drying work in with ridging extending southward into
the area from Canadian high pressure. This may push far enough
south to keep rain chances out of the area. The GEM and ECMWF are
more supportive of a dryer look while the GFS keeps front near
WI/IL with a pretty quick turnaround to a renewed return flow.
Blended pops are fairly quiet so will stick with that for now.
Tuesday night through Wednesday night - Confidence...Medium
A more northward moving low pressure system is expected to result
in a strong return flow setting up with 850/925 winds proggd to
50 knots or better on the GFS. things could end up being rather
warm and windy as this front lifts north rather quickly. With the
better mid level energy riding to our north and 850 front also
shifting north it appears we just get a quick shot of waa induced
precip as the front lifts north with higher qpf residing across
nrn WI. Cold front proggd to swing by then Wednesday afternoon or
evening. Instability axis and some higher bulk shear could result
in some heftier storm development ahead of the cold front. The 12z
ECMWF was a slightly faster solution. The GFS hangs onto the
warmer airmass into Wednesday evening. 925 temps from the GFS and
ECMWF shoot over 20c so depending on cloud cover could see some
temps near the 80 degree mark ahead of the fropa. Cold advection
will work in Wednesday night with front likely to nor traverse too
far south before yet another develops and holds it up somewhere
likely in the mid Miss Vly region.
Thursday - Confidence...Medium
A much cooler airmass settles in with cold advection in the wake
of this fropa. Although it looks like another short lived break as
the pattern continues to look active for the end of the week.
&&
.AVIATION(09Z TAFS)...VFR conditions are expected through the TAF
period. We should be dry through mid morning. Then look for a narrow
band of showers to develop mainly over far southern Wisconsin and
south into Illinois later this morning and afternoon. This may
only hit KENW, staying south of the other TAF sites, but it will
be close. CIGS/VSBYS should still remain VFR today. Then skies
clear out for tonight. Winds will be northwest to west through the
TAF period.
&&
.MARINE...A low pressure trough over the Great Lakes will continue
to push off to the east while a large high pressure system of 30.36
inches becomes centered over Wisconsin by Saturday morning. The
pressure gradient between these two systems will keep winds elevated
across Lake Michigan through tonight. The high will then drift
across the Great Lakes with light winds under that high continuing
through the weekend.
The weather becomes unsettled next week. Weak low pressure will
drift across southern Lake Michigan on Monday, bringing southerly
winds to the far southern basin with northeast winds to the north.
In the outlook, a strong low pressure system is forecast to track
from Nebraska to Lake Superior around mid week. We could see a
period of Gale Force southwest winds around that time.
