   MESOSCALE DISCUSSION 0070
   NWS STORM PREDICTION CENTER NORMAN OK
   0339 AM CST TUE FEB 02 2016

   AREAS AFFECTED...NWRN KS THROUGH SWRN...CNTRL AND ERN NEB AND
   EXTREME WRN IA

   CONCERNING...BLIZZARD 

   VALID 020939Z - 021545Z

   SUMMARY...MODERATE TO HEAVY SNOW INITIALLY OVER NWRN KS AND SWRN NEB
   WILL GRADUALLY DEVELOP NEWD THROUGH CNTRL AND ERN NEB AND EXTREME
   WRN IA THROUGH THE EARLY MORNING. BLIZZARD CONDITIONS WILL ALSO
   EVOLVE ACROSS PORTIONS OF NEB. SNOWFALL RATES OCCASIONALLY TO 1+
   INCH PER HOUR MAY OCCUR WITHIN THE HEAVIER SNOW BANDS.

   DISCUSSION...SFC LOW OVER SCNTRL KS AS OF 09Z THIS MORNING WILL
   DEEPEN AS IT DEVELOPS THROUGH ERN KS IN RESPONSE TO FORCING WITHIN
   EXIT REGION OF A NEWD-ADVANCING 150 KT UPPER JET. THE INCREASING
   GRADIENT BETWEEN DEVELOPING CYCLONE AND SFC HIGH OVER THE NRN PLAINS
   WILL RESULT IN STRENGTHENING LOW-LEVEL WINDS...WITH A 60+ KT ENELY
   850 MB JET LIKELY OVER ERN NEB BY 12Z. MODEST COLD ADVECTION AND
   EVAPORATIVE COOLING SHOULD RESULT IN SFC TEMPERATURES FALLING BELOW
   FREEZING IN MOST AREAS. SNOW BANDS SHOULD GRADUALLY BECOME BETTER
   ORGANIZED OVER NEB WITH RATES INCREASING IN ASSOCIATION WITH
   STRENGTHENING LLJ AND FRONTOGENETIC FORCING WITHIN EVOLVING
   DEFORMATION ZONE NORTH AND NORTHWEST OF THE DEEPENING CYCLONE. THE
   STRONG GRADIENT NORTH OF THE CYCLONE CENTER WILL CONTRIBUTE TO
   BLIZZARD-LIKE CONDITIONS FROM SWRN THROUGH ERN NEB AS SNOWFALL RATES
   INCREASE THROUGH THE MORNING.
