Area Forecast Discussion
National Weather Service Bismarck ND
238 PM CST Tue Dec 19 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 152 PM CST Tue Dec 19 2017

Models now in general agreement in spreading snow across northern
North Dakota beginning late tonight and continuing through
Wednesday night. Consensus among the models suggests a widespread
3 to 5 inches north of Interstate 94 with a band of 6 to 8 inches
of snow northwest and north central, along the highway 2
corridor.

So placed the winter storm warning along the expected 6-8 inch
snow band with an advisory along the southern and eastern
periphery of the warning.

The snow will begin this evening across the southwest in a broad
warm advection field associated with the baroclinic zone initially
across Montana into western South Dakota.

By Wednesday, weak h850-700 mb frontogenesis is focused across
northwest into north central North Dakota with broad scale lift
above. The above mentioned ingredients, while not particularly
strong or outstanding for heavy snow, should be aided with a deep
layer dendritic growth zone seen on model soundings between
Williston and Minot. This tilts the decision in favor of more
efficient snow production there and went with a winter storm
warning for heavy snow.

As is common with snow, there will be a rather strong gradient
and the better accumulations will fall across portions of
northern Burleigh, northern Kidder and northern Stutsman with
southern sections of these counties getting on an inch or so.

Added mention of some patchy blowing snow Wednesday and Wednesday
night with the approaching pressure rise as the low tracks east.
However widespread blowing snow is not expected.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 152 PM CST Tue Dec 19 2017

The long anticipated change to much colder weather will be seen
this extended period as temperatures steadily decreases through
the period as a deep and cold upper low migrates southwest of
Hudson Bay. The primary concern will be the cold temperatures and
the associated bitter wind chills that arrive Christmas eve
through Christmas Day and beyond. The chances for snow will be
small due to the dry nature of the arctic airmass.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1244 PM CST Tue Dec 19 2017

Vfr cigs/vsbys at all terminals through 00z Wednesday. Thereafter
expect deteriorating conditions from west to east through the
forecast period. KISN is expected to reach mvfr status by 03z
Wednesday with snow. Vsbys at KISn will worsen into the lifr range
by 15z Wednesday with snow/blowing snow. KMOT will be on a similar
path as KISN, while KDIK/KBIS should remain primarily vfr. Mvfr cigs
and ifr vsbys expected at KJMS by 14z Wednesday. Brisk easterly
winds will occur at all terminals ranging between 15kt and 25kt,
with reduced vsbys in snow/blowing snow at KISN/KMOT/KJMS.
