Areas affected...Portions of far eastern CO into western KS

Concerning...Heavy snow 

Valid 251640Z - 252145Z

SUMMARY...Moderate to heavy snow, with rates up to 1 inch per hour,
should continue in a narrow band through the afternoon.

DISCUSSION...A relatively narrow band of moderate to heavy snow is
ongoing late this morning from parts of far eastern CO into western
KS. This band is being aided by modest isentropic ascent/upslope
flow at low levels, along with mid-level frontogenesis preceding a
shortwave trough over the Great Basin and central Rockies. Within
the band, there is a focused area of 30+ dBZ reflectivity based on
recent data from KGLD. Given that the entire thermal profile is
below freezing, this area of greater reflectivity is producing
moderate to locally heavy snowfall, with rates up to 1 inch per
hour. Indeed, multiple recent surface observations confirm that
moderate to heavy snow is occurring across this area. Current
expectations are for this band to develop slowly east-southeastward
across parts of western KS through much of the early to mid
afternoon in tandem with the progression of the shortwave trough. By
21-22Z, most guidance suggests the intensity of the band should
begin to diminish as low/mid-level forcing for ascent gradually
weakens.
