MD 0028 CONCERNING HEAVY SNOW FOR PORTIONS OF KS AND SOUTHERN NE
Mesoscale Discussion 0028
NWS Storm Prediction Center Norman OK
0458 AM CST Mon Jan 25 2021
Areas affected...Portions of KS and southern NE
Concerning...Heavy snow
Valid 251058Z - 251700Z
SUMMARY...Heavy snow, with rates of 1-2 inches per hour, will likely
develop northeastward across Kansas and southern Nebraska this
morning.
DISCUSSION...Strong forcing for ascent and frontogenetic lift in the
low levels, associated with a northeastward-ejecting shortwave
trough, will aid in the development of a heavy snow band across
parts of KS into southern NE this morning. An initial mix of wintry
precipitation across parts of southwestern into central KS is
expected to quickly transition to snow as low/mid-level temperatures
cool with the approaching shortwave trough. Pronounced lift through
the saturated dendritic growth zone will likely favor heavy snow
with rates of at least 1 inch per hour for several hours in a
southwest to northeast oriented band across KS. Higher rates,
perhaps up to 2 inches per hour, appear possible on a localized
basis. This heavy snow band should shift into parts of southern NE
by mid to late morning. A very narrow corridor of freezing
rain/sleet may occur on the southeastern fringe of the band, where a
modest low-level warm nose should remain.
