What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jul 7, 2:40 PM CDT, 2 hours 45 minutes earlier.

Area forecast discussion, Jul 7, 2:40 PM CDT, 2 hours 45 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
240 PM CDT FRI JUL 7 2017

.TONIGHT - Forecast Confidence...Medium.

Water vapor/RAP animation shows fairly compact vort center dropping
southeast from vcnty of wrn Lake Superior. Influence of this wave
and some colder temps aloft will keep the chance of shra/tsra going
into the mid evening hours. Already seeing a fair amount of precip
development across NW WI. So going forecast pops look reasonable.
Once the precip diminishes things quiet down for the remainder of
the night.

.SATURDAY - Forecast Confidence...Medium.

Mid level flow remains strong from the northwest though little if
any perturbations are proggd so the going dry forecast looks good.
In the low levels an anticyclonic flow is expected. 925 temps will
be in the 16-18c range with warmest temps inland away from influence
of any onshore component.

.SATURDAY NIGHT THROUGH MONDAY - Forecast Confidence...Medium.

Short term guidance a bit less aggressive on developing warm front
and moisture return spreading into southern WI on Sunday. Low level
jet Sunday afternoon and evening looks to focus on northern IL and
IA.  Even 12z ECMWF has backed off on stronger low level moisture
convergence in southern WI. However will keep smaller chances for T
going Sunday afternoon and night. Better chance for convection over
northern WI during this time period due to passing upper level jet,
and some of the activity may sag southward into southern WI.

Better chance for more widespread convection later Sunday night into
Monday as low level jet reinvigorates and nose of jet shifts farther
northward into southern WI, shifting warm front into the area.
Precipitable water will increase to around 1.7 inches by 00z/11
which is above the 90th percentile for southern WI.  Ensemble
Situational Awarness standardized anomolies getting close to 2 units
for pwat and mean specific humidity in the low levels.  Deep warm
cloud deth over 11k feet expected by afternoon.  However Corfidi
Vectors and storm motion showing 10-20 kts which is so-so for flash
flooding concerns. Would like to see more persistent and stronger
low level convergence into the area on Monday. For now will mention
threat of heavy rainfall in Hazardous Weather Outlook for Monday.

.EXTENDED PERIOD...

MONDAY NIGHT THROUGH FRIDAY - Forecast Confidence...Medium.

The unsettled conditions look to continue through mid-week as upper
level steering winds back slightly to more zonal flow.  Zonal flow
will ensure deeper atmospheric moisture will remain close by after
frontal boundary slips just to the south Monday night.  GFS and
ECMWF in reasonable agreement on strengthening low pressure trof in
the northern plains on Tuesday, sweeping east later Wednesday into
early Thursday. Frontal boundary to the south will likely move back
north into southern WI during this period increasing the threat of
storms. 00Z ECMWF brings weak low pressure across southern WI on
Wednesday which would increase the severe weather and heavy rain
risk into the evening.  Drier conditions look to return late in the
week.

&&

.AVIATION (21Z TAFS)...

No changes to TAFS with shra/tsra development across NW WI trending
southeast. Expect this within srn WI in the 21-03z time frame. Water
vapor shows circulation vcnty western lake Superior dropping
southeast so some of the DCVA associated with this will arrive and
aid in the development despite the low level cool advection
underway. VFR CU field along and west of lake breeze boundary.
Bufkit shows several hundred J/KG of skinny CAPE so the going
POPS/timing look overall quite good at the moment. Once this settles
down towards mid evening it looks quiet into Saturday with high
pressure taking hold.

&&

.MARINE...Winds and waves are expected to remain below small craft
levels through the weekend. Onshore flow of 10 knots or less
expected on Saturday.

&&

.MKX WATCHES/WARNINGS/ADVISORIES...

WI...None.
