There is a lot going on this week as far as weather is concerned. Rain, wind, and snow are in the forecast. This active weather pattern will last through the week and could even stretch into the weekend.
First, we’ll start with the wind. A WIND ADVISORY is in effect for the Shasta Valley until 8 p.m tonight and Eastern Klamath and all of Lake Counties until 11 p.m. Sustained winds in these areas will strengthen ahead of the front up to 35 mph. Gusts up to 40 mph have already been reported from Montague and other areas could see gusts up to 45 mph. High Profile vehicles may feel crosswinds if driving in these areas tonight. Winds will calm overnight after the frontal boundary has moved through the region.
Rain has been moving in towards the region since the early afternoon and the radar is showing more on the way. Some locations along the coast and in the Cascades have reported up to a half an inch in rainfall already. The heaviest amounts will fall in the later hours of today into tomorrow. Rain will continue in the form of scattered showers tomorrow through most of the day. Cooler air aloft is creating instability in the atmosphere ahead of the system moving in. There is a slight chance of thunderstorms for tonight and tomorrow, especially along the coast and in the mountain locations. Areas to the west of Bend have already seen lightning strikes.
Snow levels are starting around 6,000′ tonight and after the cold front moves in and brings cooler temperatures, the snow levels will drop to around 3,500′. A SPECIAL WEATHER STATEMENT is in effect for the Southern Oregon Cascades and Siskiyous. Anywhere from 2-4″ of accumulating snow down to 4,000′ in the early morning hours of Tuesday. This is expected to impact mountain passes for the morning commute. Temperatures will begin rising above the freezing mark once the sun comes up, so snow is not expected to last long and any accumulation will melt off pretty quickly. Slushy and slippery roads will be the biggest concern for Tuesday morning’s commute. Allow for extra time and drive slowly.
Another round of precipitation is expected to move in with another couple of fronts on Wednesday evening. Snow levels will, once again, drop to 3,500′ and light snow accumulation is expected. Wednesday morning’s commute will be a lot like Tuesday’s. Warmer air is expected to return to the region Thursday so areas that will have been seeing snow will transition back to rain. Rain will continue at least until Saturday where we may get a slight break.
