What forecasters said that day

The local office's own words before this wind chill advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Grand Forks, ND wrote its last area forecast discussion before this wind chill advisory went out at Feb 7, 12:24 PM CST, 1 hour 58 minutes earlier.

Area forecast discussion, Feb 7, 12:24 PM CST, 1 hour 58 minutes before
Area Forecast Discussion
National Weather Service Grand Forks ND
1224 PM CST Tue Feb 7 2017

.UPDATE...

Issued at 1224 PM CST Tue Feb 7 2017

Removed the northern Red River Valley from the advisory where
conditions have quickly improved. The main snow band has exited
the forecast area to the east but elected to hold onto the
remaining Minnesota counties in the advisory for just a bit longer
due to some lingering visibility issues. Current expiration time
is 3 pm but thinking we should still be able to let it go at
least a little bit early.

Other than that, did some tweaking to sky grids with some sunshine
poking through across the Devils Lake basin and northern valley.

UPDATE Issued at 1002 AM CST Tue Feb 7 2017

Went ahead and cancelled the advisory for the far northwest
(Towner, Cavalier, Benson, and Ramsey counties) as conditions
continue to quickly improve as the system pulls away and high
pressure is beginning to nose into the western part of the state.

UPDATE Issued at 923 AM CST Tue Feb 7 2017

Ongoing forecast in pretty good shape as snow event is gradually
winding down from west to east across the forecast area. Will keep
current headlines going for now but will likely cancel the
advisory early with the next update across the west where snow has
ended and any blowing and drifting isn't too bad with visibilities
5+ miles.

Temperatures still expected to hold fairly steady for the next
few hours before cold advection behind this system really starts
to ramp up and the focus turns to tonight's wind chills.

UPDATE Issued at 636 AM CST Tue Feb 7 2017

PoPs updated this morning as intense snow band entering SE ND has
organized and extended southward into SD. Strong 700mb
frontogenetical forcing producing snowfall rates of 1 to 2 inches
per hour. Reducing the impacts of the intensity of the snow will
be the brief duration as the line clips along at 40kts.

&&

.SHORT TERM...(Today and tonight)

Issued at 400 AM CST Tue Feb 7 2017

Challenge for the forecast today includes the timing and placement
of the last round of snow in the parade of short waves that began
this past weekend across the northern plains. A robust but brief
area of snow entering the Devils Lake basin currently will
continue to quickly move to the east. Bringing the most intense
snow fall through the Red River Valley during the 6 to 9am time
frame. Snowfall rates will be up to an inch an hour however with
the quick moving nature of the system will generally see another 1
to 3 inches with the higher values along and north of HWY 2 line,
in the area of the ongoing winter weather advisory. No changes
will be made to the the headlines at this time, however a couple
runs of hires guidance do show the possibility of some 2 to 3
inch amounts across the I-94 corridor, currently a bit more than
forecast. Winds creating some drifting snow are expected with very
patchy blowing snow expected as speeds look to be in the 15 to
20kt range. Mixing layer is shallow, to 900mb at best, with around
20kts combined with the strongest cold air advection occurring
across the southern valley today.

By early afternoon the snow will quickly move east of the FA and
attention will turn to falling temps as 925mb temps crash to 20C
to 25C below by 06Z. Combined with winds will have apparent temps
fall into wind chill criteria overnight into Wednesday morning
with values ranging from 25F to 35F below.

.LONG TERM...(Wednesday through Monday)
Issued at 400 AM CST Tue Feb 7 2017

After a cold start Wednesday morning with lows 10 to 20 below
there will be minimal changes to the thermal profile, a west wind
will try to help max temps reach zero. SFC high to move to the
east and return flow with weak WAA begins Wednesday night. During
the day Thursday stronger WAA with highs to 10 to 20F continuing
to warm into the overnight. As a result there will be a brief
period of mixed precip possible Thursday night with the highest
chances across the NW MN.

Friday to Monday...Pattern changes from a split flow to high
amplitude. Longwave upper ridge over eastern Russia retrogrades
and dissipates through the period. Longwave trough over AK
amplifies through the period. Flat upper level ridge over the
western US amplifies to an upper ridge over western North America
and a longwave trough over eastern Canada. Pattern remains quite
progressive

The GFS was a little faster then the ECMWF, but by the end of the
period the GFS was the slower. Will blend the models.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)

Issued at 1224 PM CST Tue Feb 7 2017

Main snow band has exited the area but some IFR ceilings and
visibilities will linger at KBJI for a few more hours. The other
remaining sites could see a few on and off periods of MVFR
visibilities in blowing snow but conditions shouldn't be long
lived or very widespread. Northwest winds of 10-15 kts with gusts
up to 25 kts will gradually die down by this evening with VFR
conditions returning.
