Weather Washington Cascades - Extended Outlook

Issued 9-23-2015

Forecast models are somewhat a mixed bag with the forecast through October 6. With several calling for below normal temperatures and above normal precipation. Thus low confidence in the forecast. I think we will have several weak systems moving over the 10 days period  with the next one moving in late Thursday (9-24) and into Friday (9-25). Then a ridge of high pressure rebuilding later this weekend and into this Monday. I think over the 10 day period we have weak systems that move in and out of our region with light precipitation at times but much of the time will be dry.
