SPOT WEATHER FORECAST

1/9/2010 Weather

Short term: The atmosphere will stabilize and dry today as high-pressure aloft builds in eastern Washington. The next wet system with the same temperature battle will arrive tomorrow night.

Long-term: A large low pressure system circulation off the coast will drive SW flow through the PNW for the upcoming week. This will allow a series of warm fronts to pass through for the start of the week. There is hope that this pattern change will eventually degrade the eastern/western temperature battle that has been plaguing us for the past few weeks.
