MD 2013 CONCERNING BLIZZARD FOR NORTHEAST COLORADO…SOUTHEAST WYOMING…AND THE NEBRASKA PANHANDLE
Mesoscale Discussion 2013
NWS Storm Prediction Center Norman OK
1114 AM CST Tue Dec 13 2022
Areas affected...northeast Colorado...southeast Wyoming...and the
Nebraska Panhandle
Concerning...Blizzard
Valid 131714Z - 132015Z
SUMMARY...A blizzard is ongoing across portions of the central High
Plains with sustained winds of 30-35 mph and gusts to 50 mph, heavy
snow, and visibility less than 1/4 mile.
DISCUSSION...17Z surface analysis shows a ~990mb surface low near
the northwest Kansas/southwest Nebraska border with a significant
deformation zone to the west with moderate to heavy snowfall. In
addition, a tight pressure gradient on the western periphery of this
surface low has led to very strong winds of 30 to 40 mph with gusts
over 50 mph. These conditions have combined for very low visibility
with numerous observation sites at less than 1/4 mile.
Expect blizzard conditions to continue to the west/northwest of this
surface low as it lifts northeast through the day. This should
expand blizzard conditions into western South Dakota and eastern
Wyoming later this afternoon.
