What forecasters said that day

The local office's own words before this winter storm warning 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 winter storm warning went out at Oct 10, 6:59 AM CDT, 3 hours 40 minutes earlier.

Area forecast discussion, Oct 10, 6:59 AM CDT, 3 hours 40 minutes before
Area Forecast Discussion
National Weather Service Grand Forks ND
659 AM CDT Wed Oct 10 2018

.UPDATE...
Issued at 659 AM CDT Wed Oct 10 2018

Getting reports of up to an inch or so of snow in spots. Looking
at the ND/MN DOT road condition maps, the ND side is looking
worse, but so far it is mainly wet, slushy roads. There has been a
steadier snow band from Valley City to Larimore, where the ND DOT
map shows the roads to be snow covered. Will still have to monitor
for heavier snow bands today.

&&

.SHORT TERM...(Today and tonight)
Issued at 312 AM CDT Wed Oct 10 2018

The forecast remains on track, with no changes in headlines or
snowfall amounts seen at this point. The regional radars show the
steadiest band of rain from Fargo over toward Bemidji and the
Minnesota arrowhead. This band brought just under a half an inch
of rain in the past 6-8 hours to the Park Rapids area. Otherwise,
precipitation amounts so far have been lower than expected, and a
little slower moving northward. There is somewhat of a break now
over west central Minnesota, so not expecting too much more there
through sunrise. Surface temperatures have been a little cooler
from Jamestown down toward Aberdeen South Dakota. In this
corridor, the precipitation has switched over to snow. Aberdeen
mentioned that they have picked up about a half inch to an inch of
snow.

The switchover to snow should occur for most areas by sunrise.
However, not expecting enough snowfall to overcome the warm
ground temperatures this morning. So impacts this morning should
be minimal. Steady snow should occur today into tonight, with 3 to
6 inches across most of the area. Exceptions will be portions of
the Devils Lake region and west central Minnesota. A winter
weather advisory was already issued and see no reasons to change
it at this point. Will have to watch to see if any heavier bands
of snow set up. If they do, those areas will have to be closely
watched to see if more than 6 inches may occur. Lead time for
something like that would not be that great, but that is the
nature of banded snow events. Wind speeds may be a little higher
than expected, with gusts to 40 mph likely today into portions of
tonight. Outside of a heavier snow band, not expecting the snow to
blow. Conditions should begin to improve first over eastern North
Dakota this evening, but may not until very late tonight over
northwest Minnesota.

.LONG TERM...(Thursday through Tuesday)
Issued at 312 AM CDT Wed Oct 10 2018

A better balance of wet/dry weather is expected over much of the
extended forecast period, though below normal temperatures will
likely continue.

Thursday and Friday...

Precipitation is expected to gradually come to an end across north
central Minnesota early Thursday morning with slowly clearing skies
from eastern ND to northwest MN during the late afternoon/evening
hours. Drier weather will remain in place for Friday as surface high
pressure builds over the northern Plains. However, temperatures
during this period will remain on the cold side with afternoon highs
in the upper 30s and low 40s for Thur and Fri respectively.

Saturday and Sunday...

Rain and snow chances return to the region over the weekend. In the
wake of this mid week storm system a north/northwesterly flow regime
is expected to establish itself over the northern CONUS/Canada by
the weekend. An upper level shortwave embedded in this strong flow
will propagate into the northeast ND/northwest MN region early
Saturday, bringing rain north of the Highway 2 corridor. A
transition to a rain/snow mix, and eventually to all snow, is
expected overnight Saturday and into Sunday as a colder airmass on
the back side of the low swings into the region. Currently,
deterministic and ensemble guidance shows the best chance for
accumulating snow along the international border and across north
central Minnesota, however, overall snow accumulations are expected
to be light (less than one inch). Precipitation will be diminishing
during the day on Sunday with the last of the rain/snow moving out
of north central MN by the evening hours. Temperatures during this
period will continue to be on the cool side with afternoon highs
only reaching the upper 30s and low 40s.

Monday and Tuesday...

Another weak shortwave is forecast to push through the region late
in the day on Monday. This will bring additional light rain and snow
chances across the area. However, overall confidence in these precip
chances is low due to high model spread in the track of the upper
level low. As with the weekend, afternoon highs will struggle to
reach above the mid 40s.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 659 AM CDT Wed Oct 10 2018

Another day of fairly stagnant conditions, so little change is
expected for the next 24 hours. There may be some improvement
after about 18 hours, but not much until then. With daylight,
think visibilities in the snow should hold in the 1 to 3 mile
range, unless really intense snow falls. If that occurs,
visibilities could be a little worse. It will also stay on the
gusty side, with gusts to 40 mph possible.

A winter weather advisory has been posted for 3 to 6 inches of
snow, with locally higher amounts possible. Winds will also
gust up to 40 mph. The locally higher snowfall amounts may occur
within narrow bands. Impacts within these narrow snow bands will
be the greatest, with the wind driven snow causing low
visibilities. This could make the evening and Thursday morning
commutes hazardous in places.
