A high pressure offshore is wrapping around tropical moisture and funneling it into the Pacific Northwest today. Although this is tropical moisture because it is being wrapped around the ridge it is moving into the cold Gulf of Alaska before reaching our area so snow levels will start the day around 2,000 feet then climb to 3,000 feet this afternoon. We could see over a foot of new snow in the Cascades today and up to 8 inches of snow in the Siskiyou’s, including the Siskiyou Summit. Expect strong winds at the coast and east side with the strongest winds on the ridges with gusts up to 50 mph. A Winter Weather Advisory has been issued for much of the area above 2,000 feet due to snow and wind. Be prepared for hazardous winter travel over the passes today with snow covered roads and strong winds causing reduced visibility at times. Be sure to carry chains and extra supplies and check road conditions before heading out, you can find a link to Tripcheck’s website under Weather Links.
We’ll continue to see rain and snow tomorrow with the winds finally easing tomorrow afternoon and gradually drying as the high pressure offshore shifts east. With this shift we’ll see valley fog return and dry weather and we’ll again have to keep our eye on air quality by the end of the week. As of today all areas are back in the “Good” level for air quality levels thanks to all the rain, snow and wind over the weekend. Depending on how long the fog lingers into the day will really determine how much warming we can do during the day, if the fog breaks up quickly I wouldn’t rule out the valleys getting into the mid-50s in the afternoons.
I’ll be updating my Facebook with weather and road reports! Thanks for logging on and have a great Monday!
