Area forecast discussion...updated 
National Weather Service Twin Cities/Chanhassen Minnesota
623 PM CST Friday Feb 5 2016

Short term...(this evening through saturday)
issued at 320 PM CST Friday Feb 5 2016

The light snow that was forecasted across the area today was
limited to flurries due to a very dry layer blw 5k. In
addition...forcing was centered in South Dakota/NE and western
Iowa...with little forcing across southern Minnesota. Although some
flurries...or perhaps a light dusting of snow is still possible
across SC Minnesota...NE to wc WI during the evening...most areas will
remain dry. Saturday will be mild with temperatures rising above freezing
ahead of a powerful storm system developing in the northern
plains. Highs along the Buffalo Ridge will likely rise above 40
degrees...but strong SW winds developing will keep it cooler.
Elsewhere...near or slightly above freezing looks reasonable.

Long term...(saturday night through friday)
issued at 320 PM CST Friday Feb 5 2016

The long term concern turns to potential ground blizzard developing
Sunday afternoon and Sunday night across west central and southwest
Minnesota.

Models coming in better agreement in strong winds developing Sunday
across western Minnesota as an Arctic cold front drops southeast and a
deep low pressure system exits over Wisconsin Sunday night. The
GFS and European model (ecmwf) bring in strong northwest winds Sunday
afternoon...with up to 8mb pressure rises nosing into southwest
Minnesota and strong cold air advection. BUFKIT profiles indicated steep lower level
lapse rates as the front arrives. Expecting momentum Transfer to
reach near top of The Channel over the southwest. Gusts around
50 miles per hour look possible over this region. Light snow/snow showers
will accompany front and continue into Sunday night over the
southwest. This will further limit visibilities along with the
blowing snow potential. Cips analog guidance indicated greater
than 30 percent chance of blizzard conditions lasting 2-3 hours or
more. Expect the strong winds to arrive by 18z into western Minnesota and
drop south and east over southwest Minnesota lasting through
Sunday night. We have issued a blizzard watch for the western County Warning Area
for Sunday/Sunday night.

The northwest winds will continue into Monday morning over the
southwest...but any accumulating snow should come to an end. As
the low fills and moves off to the east...winds will diminish
during the day from west to east. Temperatures will struggle to
rise and may be steady or slowly fall Monday as the colder air
moves in.

The cooler than normal trend will continue through the
week....with some potential below zero readings...especially late
in the week. There is some potential of clipper type systems
affecting the area. The models are not in agreement on timing
however...so have opted to keep the longer term dry after Monday.
