A cold air mass will move into the Pacific Northwest this evening, causing quite a temperature drop in the higher elevations. Moisture is still creating rain and snow showers across the region and this will continue through the evening. Snow levels will start off around 3,000′ this evening before dropping to about 2,000′ by Sunday morning. It is possible that the higher elevations in the Valleys see a dusting to a half an inch of snow from a passing shower. Graupel was reported in some locations Saturday afternoon and it’s likely to fall again as the cold air mass moves in.
Rain and snow showers will continue through the afternoon tomorrow before another stronger cold front sweeps through from our northwest again. This storm is capable of dropping anywhere from 3”-5” in the Cascades and 1”-3” in the Siskiyous. The Rogue Valley could see 1”-2” above 2,000′. East of the Cascades 1”-2” is possible. Again, this storm will be coming through Sunday evening, so unfortunately this means the morning commute and travel Monday may be problematic in some locations, especially the mountain passes.
A good amount of moisture will stick around throughout much of the day Monday and even into Tuesday morning before we then begin to dry out. As a result, occasional rain and/or snow showers will be possible into early Tuesday. Showers will for the most part be light, however it is possible that an isolated stronger shower may develop dropping moderate to heavy precipitation.
