Area Forecast Discussion
National Weather Service Bismarck ND
601 AM CST Wed Dec 6 2017

Issued at 548 AM CST Wed Dec 6 2017

Little overall change with this update. A cool and breezy day is
expected as high pressure builds across the region. Did add PoPs
for lake effect snow showers downstream of Lake Sakakawea for late
this morning and through the afternoon with northwesterly surface
winds of 15-20kts, and a large lake surface- air temperature
differential with a cold airmass in place. Expect any lake effect
snow showers to remain west of Mandan/Bismarck for most of the
day, with a slight chance in the late afternoon or early evening
with a slightly more westward component to the wind.


.SHORT TERM...(Today and tonight)
Issued at 233 AM CST Wed Dec 6 2017

Light snow across southwest North Dakota will continue to diminish
this morning as high pressure moves in. Clouds will clear from
northeast to southwest today. A colder day is expected today
despite the clearing skies as cold air advection takes hold. With
fresh snow and mostly clear skies temperatures will fall near
zero tonight for most locations.

.LONG TERM...(Thursday through Tuesday)
Issued at 233 AM CST Wed Dec 6 2017

The long term appears rather quiet and mild as the main storm
track shifts east. We`ll see temperatures back in the 30s and 40s
by the weekend. Next week could be more active with the return of
several clippers.


.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 548 AM CST Wed Dec 6 2017

MVFR/IFR conditions in light snow and stratus across southwest and
south central North Dakota will diminish through the morning. VFR
conditions are expected thereafter across western and central
North Dakota. However, there is a slight chance for lake effect
snow showers south of Lake Sakakawea today with localized MVFR/IFR
conditions possible. Northwesterly wind gusts of 20-30kts are
expected across most of western and central North Dakota today as
high pressure builds into the area.
