   Mesoscale Discussion 0063
   NWS Storm Prediction Center Norman OK
   0401 PM CST Mon Feb 03 2025

   Areas affected...Southwest OR into extreme northern CA

   Concerning...Heavy snow 

   Valid 032201Z - 040100Z

   SUMMARY...Locally heavy snow rates will continue through the
   afternoon.

   DISCUSSION...Moderate to locally heavy precipitation is ongoing this
   afternoon from northern CA into southwest OR, in association with a
   midlevel shortwave trough and an extensive plume of moisture
   emanating from the eastern Pacific. Colder temperatures to the north
   of a stationary front across northern CA are supporting heavier snow
   rates across parts of southwest OR, including recent observations of
   heavy snow at KMFR. Moderate to locally heavy wet snow may persist
   at lower elevations through the afternoon, given the presence of
   heavier precipitation rates and a lack of near-surface warm
   advection, while heavy snow rates will continue across favored
   upslope regions at higher elevation.
