What forecasters said that day
The local office's own words before this small craft 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 small craft advisory went out at Oct 6, 3:33 AM CDT, 15 minutes earlier.
Area forecast discussion, Oct 6, 3:33 AM CDT, 15 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
333 AM CDT Fri Oct 6 2017
.DISCUSSION...
.TODAY AND TONIGHT - Confidence...Medium.
Initial surge of mid-level warm air and moisture advection producing
a few lingering -shra over southern WI. These should exit the area
in the next several hours. Another small batch is located in
eastern IA, moving northeast. Thinking most of the morning hours
will be dry as weak short wave ridging moves across southern WI but
due to lingering weak warm air advection, need to continue a lower
chance. Showers will become more widespread this afternoon and
evening as upstream mid-level short wave over MT/WY area gets nudged
eastward into the central and northern Plains ahead of increasing
zonal flow coming off the Pacific into the northwest CONUS.
Increasing southerly winds ahead of this feature will shift the warm
front now over northern IL northward across southern WI tonight.
Precipitable water values will increase to over 1.5" by 00Z with
increasing wind and moisture convergence as low level jet increases
across the area. Several periods of showers and a few t-storms are
expected during the afternoon and evening, with the shower threat
diminishing over southeast WI later tonight after the warm front
moves to the north. Central and western WI will be the primary
focus of enhanced synoptic lift from a coupled jet and this is where
the heaviest rainfall can be expected. Wl keep high pops through
the night in northwest CWA but if northward trend continues, may be
pulling back on pops in this area as well for later tonight. Lowered
rainfall amounts as well for the next 24 hours.
Saturday - Confidence...Medium
A potent 500 millibar shortwave will become slightly negatively
tilted as it rides northeast across WI. Surface/850 lows lift
across nrn WI. Plentiful moisture and enough forcing to result in
a fairly widespread rainfall with embedded thunder not out of the
question though overall instability will be limited. A little
concerned with the better focus of the dynamics and coupled jet
action being further north limiting the better rainfall amounts in
the areas that need it most in the southeast. Latest QPF reflect
this trend.
Sunday and Monday - Confidence...Medium
Mid level flow remains strong from the southwest but no
discernible waves of concern. There is a frontal boundary that is
proggd to be across the state Sunday and this shifts off to the
east for Monday. Models are dry both days. Warm 925 temps ahead of
this feature Sunday with a trend towards cold advection for
Monday. Mid level trough axis draws closer, with ECMWF faster
though still well west.
Monday night through Tuesday night - Confidence...Low
Model uncertainty pretty high this period. The GFS develops a
southern 500 millibar system at base of progressive trough and
lifts it towards WI with a more northward positioning of stronger
cyclogenesis off to our southeast. this result sin a shield of
rainfall in srn WI while the ECMWF shows ridging more pronounced
here with the 500 millibar low tracking further south and showing
a weakening tendency. This results in a much drier look for srn
WI. So at this time will carry the blended pops given the model
discrepancies in this time frame.
Wednesday - Confidence...Medium
While some synoptic details are not in sync between the ECMWF and
GFS the message is that in either case there is enough ridging to
suggest a dry forecast. 925 thermal pattern a bit warmer on the
ECMWF.
Thursday - Confidence...Low
The ECMWF eventually brings some remnants of their southern low up
into the area with a potential for some shra. Meanwhile the GFS
keeps the influence of the high in place with broad anticyclonic
wsw mid level flow. At this time the blended solution is favoring
the dry look of the GFS.
&&
.AVIATION(06Z TAFS)...General downward trend in ceiling heights
most areas with MVFR cigs now widespread over south central WI. Cigs
flirting with MVFR levels in southeast and expect downward trend to
continue as moist easterly winds increase this morning. MVFR or
lower cigs then likely to stick around until warm front passage
tonight. Some patchy fog will accompany the warm front in addition
to showers and an isolated t-storm. Wl need to include some low
level wind shear in TAF as low level jet increases across the area.
&&
.MARINE...Unsettled period expected through Saturday. Strengthening
frontal boundary over northern IL will move northward later today
and tonight across southern Lake Michigan. Deepening moisture ahead
of this approaching front will contribute to periods of showers and
possibly a t-storm this afternoon through later tonight. As warm
front moves across northern Lake Michigan late tonight and Saturday,
more scattered showers will be expected farther south, with a
continued chance for a t-storm. The approach of the warm front may
result in some patchy fog developing later today and this evening.
Increasing south winds can be expected once the warm front passes
later tonight. Wind gusts to 25 knots are expected later tonight,
and up to 30 knots on Saturday. A few wind gusts will get close to
Gale criteria on Saturday, especially later in the day as winds veer
to the southwest to west.
