MD 2058 CONCERNING HEAVY SNOW FOR SOUTHEAST NE…NORTHERN KS…SOUTHWEST IA…AND FAR NORTHWEST MO
Mesoscale Discussion 2058
NWS Storm Prediction Center Norman OK
1148 PM CST Wed Dec 21 2022
Areas affected...Southeast NE...northern KS...southwest IA...and far
northwest MO
Concerning...Heavy snow
Valid 220548Z - 220845Z
SUMMARY...A band of heavy snow with rates around 1 inch/hour and
reduced visibilities will persist during the next few hours.
DISCUSSION...Latest mosaic radar data depicts a band of moderate to
heavy snow (around 1 inch/hour) spreading east-southeastward across
parts of south-central NE behind a southward-advancing cold front.
This activity should continue to be supported by broad upper-level
divergence in the exit region of a mid/upper-level jet, along with
strong frontogenetic forcing in the 925-850-mb layer. Over the next
few hours, this band should continue spreading slowly
east-southeastward across southeast NE into far northern KS and
parts of southwest IA/northwest MO. In addition to heavy snowfall
rates of 1 inch/hour, strong/gusty northerly surface winds will
favor reduced visibilities -- even in areas of light to moderate
snow.
