STEVENS PASS MOUNTAIN WEATHER

2/28/2012 Weather

General Discussion: This morning’s radar shows the leading edge of the next front just hitting the Washington coast. The front is expected to lose some energy as it makes its way inland, so snow totals have been downgraded from earlier forecasts.

Long-term: Intermittent snow showers will continue for most of the week. Convergence conditions developing tomorrow night may bring periods of heavy snow from time to time on Thursday. The trickle in effect may produce a surprising amount of snow accumulation by Friday. Sounds like another great week of sliding.
