Area Forecast Discussion
National Weather Service Billings MT
316 PM MST Fri Nov 16 2018

.SHORT TERM...valid for Sat and Sun...

Rain was transitioning to snow over the area this afternoon as
colder air worked in from the north. Northerly winds gusting to 40
mph were also accompanying the cold air. Snow will continue
through the evening as energy moves south through the area and
upslope flow deepens. Expect roads to become slick this evening
and overnight as temperatures drop into the teens freezing the wet
and slushy surfaces. Snow will gradually decrease from north to
south overnight into Saturday. Total snowfall amounts of an inch
or two can be expected across most of the lower elevations, with
totals of 2 to 5 inches along the foothills, with locally higher
amounts possible. Totals of 5 to 10 inches can be expected over
the mountains, highest on north facing aspects. Have continued
the Winter Weather Advisories in effect for western and central
portions of the area.

Drier and cooler conditions can be expected on Saturday with highs
in the 20s, dropping into the single digits and teens Saturday
night. Lee-side troughing then looks to develop over central
Montana Saturday night tightening the pressure gradients and
increasing the winds along the western foothills for Sunday. Lows
in the teens can be expected Saturday night, with highs on Sunday
in the 40s. STP

.LONG TERM...valid for Mon...Tue...Wed...Thu...Fri...

Monday through Friday...A high pressure system builds in the west
allowing a warming and drying trend for the beginning of the
week. Lee-side troughing near the surface will allow for a tighter
pressure gradient and windier periods along the foothills and
Livingston area. Models are hinting at a shortwave to move through
the region Thursday, breaking down the ridge and allowing a more
unstable pattern to set up. Friday looks like the next chance of
precipitation so low POP`s have been added to the Friday forecast.
High temperatures look to be in the upper 40`s to lower 50`s with
lows in the high 20`s. Carrothers

.AVIATION...

The cold front has passed through the area but MVFR and IFR
conditions will continue through the evening with the passing snow
showers. Winds will continue into the early evening. Mountains
will become obscured. Conditions will improve from the north to
the south. Carrothers
