A cut-off low is currently rotating off-shore and will bring increasing clouds to the region tonight and showers to the coast tonight into tomorrow morning. Showers will also reach northern California mainly after midnight with isolated showers through the morning along and west of the Cascades with only slight chance for light showers on the east side. Showers will taper off during the morning hours and well get a break from shower activity in the afternoon before a short-wave to our north slides in bringing another round of light showers to the region Sunday evening into Monday. Most showers will form in the mountains and we could pick up 1 to 2 inches of snow in the Cascades. Snow levels tonight will hover around 3,000′ then climb during the day on Sunday to 5,000′ only to plummet again Sunday night into Monday down to 1,500′ to 2,000′. We could see snow covered roads over Lake of the Woods and Diamond Lake Summit and potentially even a dusting over Sexton Summit but travel impacts will remain minimal.
A cooling trend will develop midweek into Friday as cold Artic air spills into the area with the brunt of the cold air landing on the east side with single digit lows for the coldest spots. Temperatures on the east side in the afternoon will struggle to climb above freezing by Thursday. A short-wave could bring isolated showers Thursday to the region, mainly in the form of snow for all but west side valleys and the coast. As we head into next weekend we’ll see our next chance for a potential large storm, but since this is still a week out this is worth a mention and we’ll continue to monitor as things could easily change.
Thanks for logging on and have a great evening!
