Weather Synopsis for Saturday & Tuesday
A building upper level ridge positioned over the west coast will lift the drippy warm frontal rain currently plaguing the Olympics and Washington Cascades Saturday morning to the north and eventually out of our region. A clearing trend is expected on Saturday from south to north, with more afternoon sunshine expected for Mt. Hood and the south Washington Cascades and more lingering cloud cover closer to the Canadian border and a mix in-between. Snow/freezing levels will rise rapidly on Saturday as a warmer air mass builds over the region. The clearing trend will continue Saturday night with continued mild and dry conditions.
The strong upper level ridge will shift into eastern Washington on Sunday and the Pacific Northwest should enjoy a sunny and mild day. However, offshore flow will begin to increase late Saturday night, with cooler easterly flow muting temperatures a bit in the Cascade Passes and for the lower/mid mountain of Mt. Hood on Sunday. A weak Pacific frontal system will begin to spread mid and high clouds into the region Sunday night.
