STEVENS PASS MOUNTAIN WEATHER

10/28/2010 Weather

General Discussion:
The low pressure system stalled just off the coast, this allowed additional moisture to be entrained, so today will be more soggy than forecasted. We can still expect it to break up and be mostly dry conditions tomorrow.

Long-term:
Early next week will be very wet and very active. Typhoon Chaba, off the SE coast of Okinawa, is expected to join the deepening low in the Gulf of Alaska – this will drive several potent systems with significant amounts of moisture toward the PNW coast early next week. Rain or snow you ask, it’s too early for specific details so stay tuned.
