Forecast impact is summarized as follows:

• Speed up the timing of precipitation (snow) compared with either AVN or Eta models.
• Precipitation should be more scattered in nature due to the lack of a uniform and longer lasting Q-G (quasi-geostrophic) ascent.
• Snowfall will be tapering off by early afternoon (~20 Z, 1 PM) across the CWA as opposed to around 5 PM (00 Z) as the models suggest.
• Snowfall should be tapering off over northeastern Washington by noon (19 Z).
