MD 0041 CONCERNING HEAVY SNOW FOR SOUTHERN NEBRASKA PANHANDLE AND NORTHEASTERN COLORADO
Mesoscale Discussion 0041
NWS Storm Prediction Center Norman OK
1252 PM CST Wed Jan 11 2023
Areas affected...southern Nebraska Panhandle and Northeastern
Colorado
Concerning...Heavy snow
Valid 111852Z - 112145Z
SUMMARY...A band of heavy snow will continue to shift eastward
across the Nebraska Panhandle southward into northeastern Colorado.
Snowfall rates of 1-2"/hr will be possible.
DISCUSSION...A band of heavy snow has been ongoing across eastern
Wyoming this afternoon and continues to shift eastward across the
Nebraska Panhandle into northeastern Colorado. Surface objective
analysis and RAP model sounding indicate mid-level lapse rates
around 7 C/km coinciding with deep saturation of the dendritic
growth zone across much of the region from northeast Colorado into
the southern Nebraska Panhandle. This will support snowfall rates of
1-2"/hr. Surface observations have indicated areas of heavy snow
with <1/4 visibility across I-80 in Nebraska. Expect quick
accumulation and hazardous driving conditions due to low visibility
and accumulating snow on roadways.
