Area Forecast Discussion
National Weather Service Glasgow MT
226 PM MST Sun Feb 14 2021

.DISCUSSION...

Afternoon Update: The most notable change from the previous
forecast is with respect to precipitation potential on Tuesday.
While some of the typical blended ensembles are trending towards
almost no chance of precipitation over the region, many of both
the higher and lower resolution deterministic models are painting
a fairly broad brush of slight chances for some precipitation.
Thus, the forecast this afternoon was altered to trend somewhat
more towards the deterministic solutions. However, the rest of the
forecast remains fairly unchanged and is in good shape.

PREVIOUS DISCUSSION:
With the worst of the coldest winds chills finally moving behind
us as today progresses, we will be able to recover from the this
prolonged cold spell. Even though the coldest temperatures and
most dangerous wind chills will end later this morning, the Wind
Chill Warning will likely need to be replaced by a Wind Chill
Advisory. Will let the next shift handle that to avoid public
confusion will multiple headline products at the same time.

The unusually cold arctic air mass will shift more toward the
Great Lake region later today which will allow the beginning of a
shift in the weather pattern, bringing more moderating
temperatures to northeast Montana.

No great ridge of warm high pressure is forecast, but something of
a more progressive NW flow is expected amid a more relaxed
temperature field. Thankfully, as this next week progresses,
temperatures will steadily climb to above freezing by the latter
half of the week.

It should be noted that from Monday evening through Tuesday
morning, that a subtle embedded short wave disturbance has begun
to introduce slight chances for snow moving into portions of NE
Montana. Light accumulations if any are expected.

Otherwise, most of the expected precipitation over this next week will
be confined to the more terrain-induced areas of central and
southern Montana.

.AVIATION...

Expected Flight Category: VFR

Synopsis: A few high clouds will pass over the area, with no
impact to flight conditions. Scattered areas of light haze from
low level ice crystals will be possible today. More overcast
conditions are expected tomorrow, however ceilings should remain
VFR through the period.

Winds: Expect mostly light and variable winds through Monday for
most of the region, though areas west of and including GGW will
see a gradual increase in wind speeds out of the southeast through
the period, topping out Monday afternoon in the 15-20 kt range.
