What forecasters said that day
The local office's own words before this wind chill warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Duluth, MN wrote its last area forecast discussion before this wind chill warning went out at Jan 12, 12:09 PM CST, 2 hours 13 minutes earlier.
Area forecast discussion, Jan 12, 12:09 PM CST, 2 hours 13 minutes before
Area Forecast Discussion
National Weather Service Duluth MN
1209 PM CST Fri Jan 12 2018
.UPDATE...
Issued at 1209 PM CST Fri Jan 12 2018
High pressure continues to build into the Northern Plains. A clear
sky has resulted over much of the region. The exception is along
the south shore of Lake Superior where some lake enhanced clouds
persist. Some flurries are possible over Iron county early this
afternoon before ending as drier air prevails. Have dropped the
headlines. Will reassess for additional headlines tonight and
Saturday later this afternoon.
&&
.SHORT TERM...(Today through Saturday)
Issued at 325 AM CST Fri Jan 12 2018
At 330 this morning, it was bitterly cold across the Northland.
Temperatures ranged from 7 above at Ironwood, MI, to the 20s below
zero across much of northern Minnesota. Wind chill readings in the
25 to 40 below range were common across northeast Minnesota and
far northwest Wisconsin. Clouds lingered across most of northwest
Wisconsin, with snow showers downwind of Lake Superior.
The focus for today will be the potential for any additional snow
accumulation along the south shore of Lake Superior, as well as
wind chill readings across the rest of the region.
Today, we should see wind chill values improve somewhat by midday.
Will continue the current wind chill advisory through that time.
We will likely need additional wind chill headlines for tonight
and Saturday morning, as temperatures once again plummet across
the region. Snow showers will continue along the south shore of
Lake Superior, especially along the Gogebic Range. We could see
another inch or two, but the threat for significant additional
accumulation will decrease throughout the day as inversion heights
drop from about 1 km to 1/2 km by tonight.
Tonight, we will see lingering clouds and flurries/snow showers
across northwest Wisconsin, with mostly clear skies and bitterly
cold wind chills across the rest of the area. Overnight lows
should once again drop into the 20s to around 30 below zero in the
north.
On Saturday, we should see little change. The snow shower threat
should largely end along the south shore, with mostly sunny skies
area-wide. Highs will struggle to reach zero most areas.
.LONG TERM...(Saturday night through Thursday)
Issued at 325 AM CST Fri Jan 12 2018
The main challenges for the long term continue to be the
continued cold snap and potential for snow Sunday and Sunday
night.
Arctic high pressure will be centered in the Upper Mississippi
Valley Saturday evening and is expected to drift toward the Ohio
Valley by sunrise. A fast-moving clipper system will push out of
the Canadian Prairies and move through the western Great Lakes
Sunday and Sunday night. Light snow will accompany the passage of
the clipper system with 1 to 3 inches of accumulation expected
across the Northland. Confidence in precipitation is high. We
have increase POPs to likely or categorical, well above the
consensus blend. Nudged QPF a bit higher as well. Model profiles
suggest a deep dendritic growth zone of nearly 10kft. Think snow
ratios on the order of 20 or 22 to 1 will be likely. Another
Arctic cold front will move through the region with the clipper
bringing another round of strong northwest winds and reinforcing
the cold air over the Northland. In the wake of the clipper,
Monday through Tuesday night, northerly winds are expected over
Lake Superior which will support lake effect snow during that
time. Snow accumulations may exceed 6 inches in the snowbelt
areas of Bayfield, Ashland, and Iron Counties. The combination of
continued cold temperatures and winds will yield wind chills
colder than -25 for at least part of the Northland. Wind chill
headlines will likely be needed through Tuesday morning. Arctic
high pressure in the wake of the clipper will slowly slide
southward into the central Plains and eventually into the central
Mississippi Valley by Wednesday. As the ridge axis slides east
across Minnesota, winds will turn westerly and eventually
southwesterly ushering in warmer temperatures.
&&
.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1127 AM CST Fri Jan 12 2018
VFR conditions through the TAF period as high pressure situated
over North Dakota should remain in control through Saturday. The
main focus for this set of TAFs is the potential for MVFR and
possibly IFR ceilings and visibilities at KHIB due to upstream
anthropogenic sources. Current GOES East satellite imagery shows
the plume of clouds from these sources inching towards KHIB, so
maintained the TEMPO group from the previous KHIB TAF for the
next few hours.
