Our next band of rainfall is moving in as we speak. Some areas will see pocket of heavy rainfall overnight, with bands of heavy snow in the northern Cascades.
There is a winter weather advisory in effect for the Northern Cascades until 6 AM Sunday. Not only will there be accumulations of 4 to 8 inches at pass level and above, the winds will be gusting up to 50+ mph.
The rain and snow will taper off through Sunday morning, but a few isolated showers will stick around. While the heaviest snow will be out of the way for most of the day, make sure to take it slow and have the proper equipment when traveling through the passes. For current road conditions and advisories, you can always check ODOT’s website.
Through the week we’ll have chances of showers every day. However, not every day will be a complete wash out. Showers look a little more isolated Sunday and Monday, with temperatures warmer, in the low 50’s. The flow will be more zonal, so we’ll really only be receiving the moisture that’s coming in off the water.
Tuesday and Wednesday look to be a little wetter. We’ll be on the warm side again, with temps in the low to mid-50’s, but isolated showers on Tuesday will become scattered overnight. After that, the more persistent rain will set in Wednesday.
The coldest air will move in on Thursday with scattered showers still hanging around. Temps will likely fall into the upper 40’s, with snow levels falling to 2,500′ at times. Long range models have a nasty habit of over-hyping cold storms, so the last few I find interesting, but I’m not ready to commit. If the models prove true, a deep, cold trough will swing through by Friday afternoon. It will be some of the coldest air so far with highs only in the mid-40’s. IF (notice the all caps) this storm actually turns out to be cold, we could see the first dose of snowflakes for some of the higher hills such as the Coburg Hills. We’ll keep following this storm and see how the models trend.
