Temperatures continue to be the main challenge as Arctic air
continues to filter in across the area. Thus...adjusted temperatures a
degree or two through the rest of the afternoon. Rest of forecast
looks good.

Only minor adjustments made to temperatures over the region. Also
adjusted to reflect erosion of clouds in the Devils Lake basin as
drier Arctic air continues to push south. Otherwise...rest of
forecast on target.

Short term...(today through monday)
issued at 345 am CST sun Dec 28 2014

Surface high pressure in southern Manitoba will build southward
into the Red River basin through the day today...with northerly
winds and steadily clearing skies pushing from north to south
through midmorning... and sunny but chilly conditions throughout
the afternoon.

Deep cold advection will continue well into the overnight tonight
..and with light but persistent northerly winds...Will produce
subzero cold temperatures and bitter wind chills for tonight and
Monday.

Long term...(monday night through saturday)
issued at 345 am CST sun Dec 28 2014

Monday night and Tuesday...will see the center of our Arctic cold
airmass well entrenched over the dktas and Minnesota with overall
temperatures remaining well below seasonal normals. Sunny... dry
and cold persisting.

Wednesday through Sat... a by midweek we can expect a transition to more
of a upper level splt flow pattern across western noam... with
Arctic air shunting further into eastern Canada. Midweek
temperatures will climb back toward seasonal norms as a more mile
west to northwest boundary layer flow resumes over the northern
plains. A series of weak disturbances near the end of the week
will provide some low chances for light snow showers...but nothing
on the horizon as far as significant snow producers. Cold air
returns to the region next weekend after a stronger low pressure
system kicks out of the SW Continental U.S...moves up through the Ohio Valley
region and into the NE Continental U.S..
