.SHORT TERM...(Today and tonight)
Issued at 326 AM CST Sat Nov 18 2017

Current surface analysis places low over the southern/central
plains with high along the Alberta/Saskatchewan border stretching
into Montana. Upper level analysis places low pushing into western
Hudson Bay, with trough stretching south/southeasterly towards the
central plains. Weak wave sliding along the backside of the trough
is producing some light snow over portions of north central North
Dakota, though this has been diminishing some over the past hour.

Aforementioned light snow will continue to push to the east and
diminish early this morning. Otherwise, a quiet day is expected
with clearing skies as ridge to the west starts to build in. Quiet
weather remains into tonight.

.LONG TERM...(Sunday through Friday)
Issued at 326 AM CST Sat Nov 18 2017

Ridge builds into the area on Sunday bringing warming temperatures
to the area. Warmer temperatures remain into Monday before a
clipper zips through the area Monday night into Tuesday. No
precipitation is expected, though breezy conditions will develop
and temperatures will be much cooler on Tuesday. Ridge then
rebuilds into the area bringing a gradual warming trend to the
area Wednesday through Friday. Dry conditions expected through
Thursday, with some low precipitation chances over portions of the
area developing on Friday as the ridge flattens and some weak
waves push into the area.
