   Mesoscale Discussion 0210
   NWS Storm Prediction Center Norman OK
   0545 PM CDT Thu Mar 19 2020

   Areas affected...North central NE through northeast CO

   Concerning...Heavy snow 

   Valid 192245Z - 200145Z

   SUMMARY...Heavy snow and periodic blizzard conditions will continue
   across north-central Nebraska through northeast Colorado through

   DISCUSSION...Recent regional radar imagery shows an organized snow
   band associated with a region of strong 700 mb frontogenesis and
   deformation extending from northeast CO northeastward into north
   central NE. Synoptic ascent associated with an ejecting upper level
   low overlapping with this mesoscale forcing are driving heavy
   snowfall rates between one to two inches per hour. 

   Additionally, strong cold advection in the low levels are steepening
   low level lapse rates that will enable efficient downward mixing of
   30-40 knot winds above the surface. The combination of heavy snow
   and strong winds are causing persistent blizzard conditions across
   northeast CO where low level winds are strongest and periodic
   blizzard conditions further northeast into NE. Recent hi-res
   guidance suggests that continued deep lift and cooling throughout
   the column will continue to support these winter conditions through
   00 UTC when pressure gradient winds and forcing for ascent diminish
   with the eastward translation of the low.
