Convergence Zone snow hits I90
My son is turning back from his trip to Snoqualmie Pass for his snowboard lesson. The reason....too much snow and chains are required. The convergence zone has moved south and is now aligned nearly NW-SE...with the heaviest amounts aligned on I90 at and west of the Pass. The radar shows the story...and look at the cam up there--snowy driving. Convergence zones can greatly enhanced the snow at Stevens or Snoqualmie...depending exactly on how they set up. Outside of the convergence zone, some of you getting bright sunshine (see high res sat picture).
The heavier showers are now approaching western Washington....
