Area Forecast Discussion
National Weather Service Bismarck ND
344 AM CST Sat Dec 3 2016

.SHORT TERM...(Today and tonight)
Issued at 314 AM CST Sat Dec 3 2016

Current surface analysis places low over southern Alberta with
trough dropping through eastern Montana towards the Black Hills.
High remains over the central plains into the midwest. Upper level
analysis places short wave sliding through central into eastern
Montana producing some light snow. Over our area, skies have
gradually been clearing over western locations with some fog
developing, while cloud cover lingers over the east.

For today...areas of fog will dissipated by mid-morning as
aforementioned short wave continues its approach. Areas of snow
will develop and push over the area today into this evening,
although accumulations should remain on the light side.

.LONG TERM...(Sunday through Friday)
Issued at 314 AM CST Sat Dec 3 2016

Weak ridging between systems will bring dry conditions during the
day on Sunday. Our first real shot of cold air for the season
will start to push into the area on Monday as a surface low
deepens over the plains and lifts over Manitoba/Ontario allowing
an arctic airmass to pour into the region. This will also bring a
good chance for snow through the area with modest isentropic lift
to start followed by enhanced broad scale lift from trough
swinging around upper low to the north. Temperatures will fall
through the day on Tuesday as cold air continues to pour in, while
breezy conditions will contribute to bringing frigid wind chill
values, particularly Tuesday night/early Wednesday where readings
as low as 30 below are expected. Frigid airmass remains over the
area through remainder of the work week.
