   Mesoscale Discussion 1965
   NWS Storm Prediction Center Norman OK
   0915 PM CST Fri Nov 18 2022

   Areas affected...portions of extreme southwest New York

   Concerning...Heavy snow 

   Valid 190315Z - 190715Z

   SUMMARY...Occasional bouts of heavy snow, perhaps briefly exceeding
   1 inch/hr, remains possible with a primary snow band this evening,
   which is shifting northward towards Buffalo, NY. Areas of heaviest
   snow should be confined to about 30 miles inland from Lake Erie.

   DISCUSSION...A lingering snow band continues to promote moderate to
   heavy snow to areas immediately east of the Lake Erie shoreline. The
   approach of a very subtle mid-level impulse, currently over the
   Great lakes, is contributing to increased cyclonic upper flow and
   slight backing of the vertical wind field, supporting a gradual
   northward shift of the snow band. Though deep-layer ascent should
   weaken across western NY, 8 C/km low-level lapse rates overspread by
   a near-saturated dendritic growth zone should continue to support
   moderate to heavy snow across the Buffalo, NY area through at least
   early tonight. While there are some indications that this snow band
   is weakening, it is not out of the question for occasional heavy
   bursts of snow (perhaps briefly exceeding 1 inch/hr rates) to occur
   near the Lake Erie shoreline. As such, areas closest to the shore
   may experience brief periods of significantly reduced visibility and
   hazardous road conditions.
