Weather Washington Cascades - Extended Outlook

Issued 9-29-2015

Forecast models continue with the pattern of a ridge of high pressure (see 500 mb map) at the surface and aloft will remain over our region for much of the time between now and October 9 although it will break down at times, like later this Friday 10-2.  Thus above normal temperatures and below to  normal precipitation will be the rule. However low confidence in the models since they have been jumping around a lot lately.
