MD 0139 CONCERNING HEAVY SNOW FOR CENTRAL AND EASTERN KS

Mesoscale Discussion 0139
NWS Storm Prediction Center Norman OK
0123 AM CST Sun Mar 03 2019

Areas affected...central and eastern KS

Concerning...Heavy snow 

Valid 030723Z - 031130Z

SUMMARY...Periods of moderate to heavy snow with rates around 1 inch
per hour are expected across parts of central into eastern KS
through the early morning hours. Gusty winds also will lead to
blowing and drifting snow and further reducing visibility.

DISCUSSION...Moderate to heavy snow has been tracking east from
western in central KS over the last few hours. Some heavier bands
have been noted over southwest into south-central KS the last 1-2
hours in particular. This area of snow is associated with broad
ascent as a shortwave trough ejects from eastern CO into the central
Plains in otherwise low-amplitude westerly flow regime. 07z
mesoanalysis indicates the dendritic growth zone thickness ranges
from about 2-3 kft with a nearly saturated layer extending from near
the surface through the dendritic growth zone. This will aid in
periods of heavy snow, approaching 1 inch per hour at times, as
stronger forcing shifts eastward in conjunction with modest
frontogenesis around 700mb. Some areas across central KS could see
brief periods of heavier snow rates around 1.5-2 inches per hour. In
addition to periods of moderate to heavy snow, north-northeast winds
around 15 mph with gusts to 25 mph will create areas of blowing and
drifting snow and further reduce visibility into the early morning
hours.
