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 Mar 25, 2:29 PM CDT, 16 minutes earlier.

Area forecast discussion, Mar 25, 2:29 PM CDT, 16 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
229 PM CDT Sun Mar 25 2018

.DISCUSSION...

Tonight...Forecast confidence is high.

High pressure will continue to keep the area dry and mostly clear
overnight. But, it will be sliding off to the east by morning.
Another cold night with temps in the 20s.

Monday thru Tuesday night...Forecast confidence is high.

This remains a wet period. Look for moisture to surge north into
the area during the afternoon as troughing develops to the west.
Precipitable water values are still expected to climb to around 1
inch Monday night. The H8 warm front reaches the IL/WI border
right around 00z Tue, signaling the arrival of the deeper
saturation. We could see some leading showers push into southern
Wisconsin by mid afternoon, but the main thrust of rain will hit
as that elevated warm front and eventually the surface warm front
move in. Monday night will see widespread showers and possibly
even isolated thunderstorms. Little spread in the temp/dew point
will result in areas of fog as well. Total rainfall is in the
0.50" to 0.70".

The surface/H8 trough are pushing east already by sunrise on
Tuesday with any lingering rain likely ending from west to east by
late morning. Areas from Madison on west may be dry all day on
Tuesday, with the rain hanging on a bit longer across the
southeast. Tuesday may not be a complete wash-out as was
anticipated earlier.

Wednesday and Thursday...Forecast confidence is high.

Wednesday is the pick day of the week. We should get into some
decent sunshine with highs in the 50s. Winds will be on the
lighter side.

A trough/cold front pushes across the Great Lakes Wednesday night,
exiting east in the morning. This could bring us some light
precip, but it also signals a shift toward a cooler stretch of
weather for the end of next week.

Friday through Sunday...Forecast confidence is medium.

The upper pattern is fast and noisy and results in lots of small
chances of precipitation at the end of the week. The GFS is trying
to bring in a focused band of snow across southern Wisconsin on
Saturday, while the ECMWF is looking drier, though it does have
developing low pressure to the west. This model discrepancy is
typical of a fast flow and resolving these details is difficult to
impossible this far out. We'll have to let this one play out for a
few days.

&&

.AVIATION(18Z TAFS)...

VFR conditions can be expected through 18z Monday. MVFR CIGS will
then spread quickly north through the area after about 20-21z
Monday as moisture moves in ahead of an approaching low pressure
system. Look for the east winds to subside tonight, then veer
southeast by Monday morning. The southeast winds will increase
again by mid day on Monday.

&&

.MARINE...

Another small craft advisory goes into effect at 10 pm this
evening and will run through 10 am on Tuesday due to persistent
elevated southeast winds ahead of approaching low pressure.
