Mesoscale Discussion 0470
NWS Storm Prediction Center Norman OK
0430 AM CDT Wed Apr 13 2022

Areas affected...central and northern ND

Concerning...Heavy snow 

Valid 130930Z - 131330Z

SUMMARY...Heavy snowfall rates around 1.0 to 1.5 inches per hour
(localized rates around 2 inches per hour) are forecast through the
early morning.

DISCUSSION...Water-vapor imagery shows a slow-moving mid-level low
over the western Dakotas with a mid-level dryslot wrapping
cyclonically through the southeast quadrant of the larger-scale
mid-level circulation.  Radar mosaic shows a substantial snowfall
shield from near Bismarck northward to Minot during the past few
hours.  Model guidance indicates strong frontogenesis in the 850-700
mb layer.  Coupled with the strong large-scale ascent via the
mid-level low, a deep layer of forced ascent within a saturated
column will continue to yield heavy snowfall rates for the next
several hours from near I-94 in central ND northward to the 48th
parallel.  Snowfall rates 1.0-1.5 inches per hour will likely occur
with locally heavier bursts possible.
