The first of many storms systems this week will move into the Northwest today. This will bring in rain, wind and much cooler air. Snow levels will initially start off high today, around 6,000.’ By tonight and Wednesday morning they’ll hover around 4,000′ but could be as low as 3,500′ during times of heavier precipitation.
This of course means some travel impacts are likely for the Wednesday morning commute, most of concern is Siskiyou Summit. Highway 140 and Highway 66 will likely have travel impacts as well later Tuesday through Wednesday morning and then again Wednesday night and Thursday morning. If you are traveling into the passes the next few days, be sure to check TripCheck and carry chains.
Tuesday will bring periods of rain and even isolated t-storms to Southern Oregon. The best chance for a thunderstorm though will be west of the Cascades. Small hail and heavy rain is possible with any storms that do develop. Wednesday, another system will follow, continuing to bring wet weather to the region. An even more potent storm is expected to move in for the end of the week and into Saturday. This system will have a tropical connection, meaning a lot of rain is expected throughout this time period.
