NWS Storm Prediction Center Norman OK
0446 AM CST Sun Dec 29 2019

Areas affected...portions of northern/western Minnesota...eastern
North Dakota and northeast South Dakota

Concerning...Heavy snow 

Valid 291046Z - 291445Z

SUMMARY...Snow will increase in intensity through 15Z with rates of
one inch/hour possible.

DISCUSSION...Upper-level low pressure was gradually deepening in the
vicinity of the KS/NE border at 10Z while moving slowly northeast. 
Broad surface low pressure was located over Iowa with a warm front
extending east/southeast across northern IL. An increase in
large-scale lift is expected across the discussion area through mid
morning as heights fall with the approaching/deepening system,
coupled with low-level warm advection in the 850-700 mb layer.  As a
result, snow intensity should increase over the next few hours with
rates of one inch/hour possible through 15Z.
