Why are snowstorms rare over the western Washington lowlands?

  • To get snow you need cold and wet.

  • It is easy to be mild and wet here

  • Sometimes we are cold and dry (this week!).

  • To get cold and wet is very hard…but why?







































Why so icy?

  • Since it is usually mild here, the surface ground temperatures are generally above freezing.

  • Snow falls on the roads and is not removed or plowed to the side (you know who to talk to about that!).

  • The snow starts to melt, but then cooler temperatures behind the weather disturbance freezes the air slush into ice.

  • Now it is impossible to remove without salt or a warm up.









Snowstorms are the most difficult forecast problem for meteorologists

  • Why? Have to accurately predict temperature and precipitation amount to get the forecast right.

  • Not much practice!

  • Often right on the edge of rain or snow



Seattle Times Feb 1999



We are getting many of the snowstorms generally right now, but not all.





Communication of snow forecasts is still an issue. There is a major problem for local meteorologists…..
