Mesoscale Discussion 2057
NWS Storm Prediction Center Norman OK
0701 PM CST Wed Dec 21 2022
Areas affected...Southern SD...parts of NE... far southeast WY...and
northeast CO
Concerning...Blizzard
Valid 220101Z - 220500Z
SUMMARY...Reduced visibilities in blowing snow and localized
ground-blizzard conditions are possible across parts of the northern
and central Plains into the overnight hours.
DISCUSSION...Latest surface observations show 25-35 mph sustained
northerly surface winds (with gusts upwards of 45 mph) across parts
of the northern and central Plains -- behind a strong
southward-advancing cold front. These strong/gusty surface winds,
coupled with very cold surface temperatures (-05 to -15 F), are
yielding locally favorable conditions for reduced visibilities in
blowing snow -- despite only light to moderate ongoing snow over the
area. Visibilities of 1/2 to 1/4 mile are possible into the
overnight hours -- especially over areas that continue to experience
at least light to moderate snow showers amid the strong/gusty winds.
