Mesoscale Discussion 2047
NWS Storm Prediction Center Norman OK
1046 AM CST Thu Dec 15 2022

Areas affected...Northwest Minnesota...eastern North Dakota...and
far northeast South Dakota.

Concerning...Heavy snow=20

Valid 151646Z - 152045Z

SUMMARY...Moderate snow will advance westward through mid-afternoon.

DISCUSSION...Moderate to locally heavy snow is currently being
observed near the North Dakota/Minnesota border and vicinity. This
area of enhanced snowfall is associated with a westward moving
upper-level trough which has now wrapped around the parent
upper-level low. Moderate to locally heavy snow will continue to
advance westward through mid-afternoon before starting to weaken as
the shortwave trough slows and eventually stalls as it gets absorbed
by the upper low.=20

In addition to the moderate to heavy snow, some visibility
reductions can be expected amid surface winds of 25 to 30 mph and
gusts to 40 mph within the tight pressure gradient on the west side
of the surface low. Despite weakening snowfall rates this
afternoon/evening, blowing snow and associated visibility
restrictions are expected to persist through the overnight period as
the surface low moves slowly northeast and the pressure gradient
remains across the region.
