Mesoscale Discussion 2017
NWS Storm Prediction Center Norman OK
0241 PM CST Tue Dec 13 2022
Areas affected...portions of the central High Plains
Concerning...Blizzard
Valid 132041Z - 140045Z
SUMMARY...Blizzard conditions are ongoing from northeast Colorado,
across the Nebraska Panhandle, and into southwest South Dakota.
These conditions should continue through the evening and into the
overnight hours across South Dakota
DISCUSSION...Blizzard conditions continue to spread north across the
central Plains as a 991mb surface low lifts northeast across
Nebraska. A peak wind gust of 55 knots was recently observed at
Rapid City with persistent gusts near 50 knots over the last 2
hours. Heavy snow is approaching this region from the east with
rapidly deteriorating visibilities expected as snowfall rates of 1
to 2 inches per hour combine with the very strong winds. Winds will
likely peak this afternoon, but will be slow to wane as the surface
low stalls across eastern Nebraska tonight. Blizzard or near
blizzard conditions will likely persist for much of the overnight
period across southwest South Dakota.
