What forecasters said that day

The local office's own words before this winter weather 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 winter weather advisory went out at Oct 9, 3:00 PM CDT, 11 minutes earlier.

Area forecast discussion, Oct 9, 3:00 PM CDT, 11 minutes before
Area Forecast Discussion
National Weather Service Grand Forks ND
300 PM CDT Tue Oct 9 2018

.SHORT TERM...(This evening through Wednesday)
Issued at 300 PM CDT Tue Oct 9 2018

Snow totals and winter headlines will be the main headaches for
the period.

Water vapor loop shows the main upper trough over CO/NM, with a
kicker system digging down through OR/ID that will help push the
more southeasterly trough into the Northern Plains by Wednesday
afternoon. The surface low is still well to our south over KS, but
will move quickly northeastward tonight into IA/southern MN and
then into the Great Lake for tomorrow. There will be plenty of
synoptic lift from the trough as it lifts into our area, and the
models continue to indicate strong 700mb frontogenesis setting up
over our area tonight into tomorrow. Rain currently moving through
eastern SD will enter our southern counties this evening, pushing
northward throughout the night. The main deformation band will
continue over the central CWA for much of the day tomorrow, before
weakening and pushing eastward during the late afternoon and
evening.

The biggest question is not if we will get rain and snow, which is
yes, but how much snow will accumulate and what the impacts will
be. GEFS plumes are still all over the place with snow amounts,
ranging from less than an inch of accumulation to near 10 inches
at KBDE. There will be a decent amount of cold air coming down the
backside of the low pressure system, along with strong northwest
winds. However, quite a bit of the QPF will be falling during the
daytime hours, and there should be at least some melting as snow
falls. With the melting and compaction of wet snow, think that
even with 0.5 to 1.5 inch of QPF there will be a pretty broad area
of 3 to 6 inches. The exception of this will be where any
mesoscale banding sets up, the exact location still unknown. Could
see more than 6 inches to even warning level snow amounts in that
band, but again, do not know the exact location at this point.
Thus, will put out a broad winter weather advisory, and highlight
in the wording there will be a narrow band of heavier snow.
Visibilities will also be reduced within that narrow band,
although with the wet snow it will be more splattering on north
facing surfaces vs blowing.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 300 PM CDT Tue Oct 9 2018

Potent storm affecting the forecast area on Wed will see snow
gradually taper off from southwest to northeast during Wed night
into Thu morning, ending over north central MN by early Thu morning.

Cool and breezy, but drier weather will move back into the region
for Thu as temperatures remain solidly in the 30s. Zonal flow and
modest warm air advection will result in some warming into the 40s
on Sat as a clipper system moving out of Canada brings rain and snow
chances to northeast ND and northwest MN. Overall winter weather
impacts are expected to be minimal at this time. Any residual pcpn
will move east during Sun with temps dipping well below average once
again. Another clipper offering chances for mixed pcpn is scheduled
for Tue with some hope for moderation in temps maybe to near normal
by the end of next week or next weekend.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1243 PM CDT Tue Oct 9 2018

MVFR conditions with some patches of BR and drizzle, although none
impacting the TAF sites at this point. Will amend as needed
through the afternoon hours. Mostly MVFR stratus will continue
into this evening, with deteriorating visibilities and ceilings as
a band of mixed rain and snow moves into the area. By tomorrow
morning, ceilings will be down below 1000 ft in most areas and
some vis will be down to 1-3SM with -SN. With heavier bands some
vis below 1SM is not out of the question, but unknown if the
heavier snow bands will impact a TAF site at this point. Winds
will be breezy out of the northeast today, shifting to the
northwest tonight and tomorrow and increasing. Speeds of 20 kts
with gusts to 25 to 30 kts are possible late in the period.
