Area Forecast Discussion
National Weather Service Billings MT
307 PM MST Fri Feb 5 2021

.DISCUSSION...
Tonight through Saturday Night...

Widespread severe winter weather coming through the weekend.
We're just getting started. Have made no changes to the winter
weather highlights that go through Sunday.

Backdooring cold front has finally pushed through Big Timber,
where winds have just shifted to the northeast. Temps are slowly
falling but not enough to prevent area roads from becoming wet. In
addition, temps are still in the low 30s at Livingston where winds
are still downsloping. As a result, expect roads to turn icy as we
reach the late afternoon and early evening. A heads up for your
evening commute.

Snow has taken a banded form over our west in response to steep
mid level lapse rates (7.5 C/km) in a region of intense 850mb
frontogenesis. Over the next several hours, locations from
Billings west will likely see locally very heavy snow with these
bands, which will slowly push toward the foothills (i.e.
Livingston-Red Lodge) as the front backs all the way to the
foothills. Something to watch.

Satellite imagery shows a shortwave dropping thru southern
Alberta. This wave along with deepening cold air will enhance the
snowfall across our cwa tonight (including our southeast). Late
tonight we should see snow become lighter and be focused in our
west, with a push of drier air in our east. By early Saturday,
onset of next period of moist isentropic ascent begins as a wave
drops out of the NW (this is the well-defined feature currently
over southeast AK). Mid level warm advection combined with
continued surface cooling will result in a deepening of the
dendritic layer, expected to extend from the surface to near
650mb, with steep lapse rates remaining on top of this layer.
Saturday afternoon and night should see healthy snow accumulations
with fairly high snow ratios. All of this is well-covered in our
winter highlights, but have raised pops and QPF a bit for this
period of time, especially across our west and south, but eastern
areas will see precip too.

Temperatures north of the arctic front are quite cold, -4F at
Calgary at 22z. We will tap into this air mass late tonight and
tomorrow. Today was our transition day while Saturday will be the
first of some really cold days. Should see lows push or fall below
zero tonight, with highs in the single digits and lower teens most
areas Saturday.

JKL

Sunday through Friday...

Moist northwest flow moving over the cold air in place will
continue snow through Sunday morning, gradually diminishing from
the northeast into Sunday night. Another impulse dropping in from
the northwest should increase snow chances once again into Monday,
although amounts look to be on the light side. After Monday, snow
looks possible at times through much of the week as an arctic
airmass remains over the region, and weak moisture and energy
advection continue. Given dendritic growth will be limited to
nonexistent with the cold air in place for the coming week, snow
accumulations will generally be light.

The bigger story for the coming week continues to be the very cold
temperatures that are expected as strong surface high pressure
settles into the region. High temperatures are forecast to range
from the single digits above and below zero most days through at
least Wednesday and perhaps through the coming weekend, although
there is some uncertainty from Thursday onward. For now we
gradually warm temperatures into the end of the week (lower teens
instead of single digits). Low temperatures down into the teens
below zero will be commonplace, along with bitter wind chills.
Some of the coldest nights could see many places dropping into the
20s below zero for temperatures as well. If and when the Arctic
airmass decides to leave, downslope flow would increase winds
along the western foothills, and causing blowing snow concerns. STP

.AVIATION...

Poor flying weather will impact the region through Saturday (and
the entire weekend). Expect widespread MVFR-LIFR in snow, with
lowest cigs/vsbys west of KMLS. Mountains will be continuously
obscured.
