Widespread breezy winds Sunday. && .SYNOPSIS... Calm conditions expected Friday night. A stronger system Saturday into Sunday will bring widespread lowland rain, mountain snow, and widespread breezy winds. && .DISCUSSION... Tonight through Sunday: The breezy winds behind the earlier cold front will calm through the evening and overnight Friday into Saturday. By Saturday morning, a brief ridge pattern will be in place over the region as a robust Low begins to press into the Pacific Northwest. The Low will support a decent plume of moisture pushing into the Inland Northwest and bring widespread showers. Precipitable water values will increase to 0.75-1.0 through Sunday. Snow levels will range from 4000-4500ft. Ensembles have increased the snow amounts for the Cascade Mountain passes. An advisory has been issued for Washington Pass for possible winter travel conditions on Sunday. It can bring travel issues to Stevens and Washington Passes with a 60-70% probability of 24 hour snow total of 4 inches. The lower elevations of Washington can expect rain ranging from 0.10-0.40. Idaho Panhandle amounts range from 0.70-1.00. Winds will increase across the Basin with the system passage with sustained speeds of 25 to 25 mph and gusts peaking around 40 mph on Sunday afternoon. Winds could be locally stronger around the Blues with gusts near 50 mph possible. Highs will continue to 50s to low 60s. Overnight lows will trend warmer with the increasing clouds decreasing the radiative cooling efficiency. Lows will be in the upper 30s and 40s. Monday through Thursday: Ensembles are building a ridge over the region for the start of next week. It will bring a dry trend through Wednesday. The ridge will also stall a Low over the Gulf of Alaska. Ensembles are bringing the Low across the Pacific Northwest next weekend. It has potential to bring impactful mountain snow and rain to the Inland Northwest. Highs will continue to be in the 50s and low 60s. Lows will drop back to the upper 20s and 30s. /JDC && .AVIATION... 00Z TAFS: Sky conditions are clearing behind the exiting cold front. TAF sites are generally expected to be VFR.
