12/2/2011 Weather
General Discussion: The high pressure system, sitting off the PNW coast, shifted slightly to the east last night. This shift allowed some cool, unstable air to makes its way south, hence the dusting of snow. These small weak disturbances with periods of sun shine will be the pattern through the weekend.
Long-term: With the exception of few disturbances hanging around, this dry weather pattern is expected to continue into and possible through next week. A change is anticipated by the middle of next week with a more active winter weather pattern hopeful by next weekend.
Another point of interest is that the same large high pressure system off our coast is also responsible for the record breaking Santa Ana winds in California. Impressive 180mph east winds pouring of the Sierra Mountains.
