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 Bismarck, ND wrote its last area forecast discussion before this winter storm warning went out at Apr 1, 11:35 AM MDT, 1 hour 32 minutes earlier.

Area forecast discussion, Apr 1, 11:35 AM MDT, 1 hour 32 minutes before
Area Forecast Discussion
National Weather Service Bismarck ND
1235 PM CDT Sun Apr 1 2018

.UPDATE...
Issued at 1228 PM CDT Sun Apr 1 2018

Guidance continues to come in with the NAM remaining further north
on the H700 mb low and the QPF. Latest Superblend keeps the QPF
across the southern third of teh state. Will probably trend toward
this solution.

UPDATE Issued at 855 AM CDT Sun Apr 1 2018

Without much new guidance will update the current observations
only. Will want to see the new NAM as yesterday it was the
outlier.

UPDATE Issued at 629 AM CDT Sun Apr 1 2018

Current temperatures dropping below forecast in some areas so
updated latest temperatures and blended to mid-morning values.
Otherwise no changes to the current forecast. Updated text
products will be sent shortly.

.SHORT TERM...(Today and tonight)
Issued at 322 AM CDT Sun Apr 1 2018

Quiet for the short term period.

Clear and cold today but not windy like Saturday so drifting snow
across roadways, melting and re-freezing should not be a problem
today. Although icy spots still remain from yesterday. With abundant
sunshine, even starting out so cold, we should still recover nicely
with highs in the 20s most areas but 30s southwest. Not great for
early April, but it will feel much nicer than Saturday.

Clouds begin to increase late in the day west with skies becoming
mostly cloudy tonight ahead of the next system that impacts the area
on Monday.

.LONG TERM...(Monday through Saturday)
Issued at 322 AM CDT Sun Apr 1 2018

Upper level low along the central British Columbia coast will
continue to drop south into the northern Rockies by early
Monday. The low then propagates south and east through the
northern high plains and into the northern plains by early
Tuesday. Surface low pressure develops ahead of the trough over
the central high plains Sunday night, and tracks across the
central/southern plains through Tuesday.

The mid and upper level system tracks across southern Montana and
along the ND/SD border producing a swath of precipitation that
spreads across North Dakota Monday and Monday night.

Previous runs have been farther south, but the latest 00 UTC runs
from the ECMWF and NAM have shifted farther north. The GFS did
shift the qpf a little south from its previous run but qpf
amounts were higher. A look at the GFS shows an extended period
of synoptic scale ascent across southern North Dakota Monday and
Monday night. But the lower level frontogenetic forcing is
maximized south of the forecast area. this seems reasonable, but
the forcing is close enough to the far southwest to be concerned.
The track of the 70H low is favorable for southwest ND and with
the NAM and especially the EC farther north with the qpf pattern,
have decided to issue a watch for the far southwest portion of
North Dakota. We do think the NAM may be too far north so it's qpf
pattern was minimized on Monday. SuperBlend seemed too far north
due to the northern displacement of NAM QPF, so we tempered this
solution with a mix of GFS/EC and Canadian qpf, which maximized
precipitation over the far southwest, instead of as far north as
Lake Sakakawea given the NAM. The O6 UTC NAM remains north, so
much uncertainty still remains with the eventual snowfall. Models
continue to favor all snow, so we got rid of the widespread
freezing rain the model blend was giving us Monday morning.

At this time it looks like the far southwest would be favored for
Warning criteria snow amounts, thus the warning. And with
collaboration with MT offices and UNR it blends well with their
snowfall solution. We will continue the SPS and expand it
eastward to cover the entire forecast area along and south of
Interstate 94, as Advisory Snow amounts could occur if current
model trends hold.

Northwest flow aloft and surface high pressure over western and
central North Dakota will allow for dry conditions through the
week. The exception to this will be light snow potential across
southwest North Dakota Wednesday night through Friday, closest to
a meandering baroclinic zone with weak synoptic scale ascent
periodically pushing over this boundary. The rest of western and
central North Dakota looks dry and cold Tuesday through Friday.
Although there are timing differences, both the GFS/ECMWF show a
more significant system possibly impacting western and central ND
next weekend and/or into early the following week.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1228 PM CDT Sun Apr 1 2018

Arctic high over the region at Noon CDT will move east of teh
region as a developing winter storm across Wyoming and Montana
will move east tonight. Expect deteriorating conditions to MVFR
after 06-10z across the region and IFR KDIK in snow after 12Z.

Issued at 855 AM CDT Sun Apr 1 2018

Primary river gauge at MDNN8, the Heart river at the highway 10
