Conditions will remain dry through the evening and into the first half of Presidents’ Day. As Monday evening nears, cloud cover will increase and winds will pick up ahead of the next storm system. Snow levels are going to drop quite a bit with a much colder air mass moving into the higher elevations. The widespread and heaviest precipitation will move to our South, so Siskiyou County will be seeing a good 2″-4″ from this storm system by the time all is said and done. Snow will begin in Northern California by late evening Monday, with the heaviest snow occurring between about 6AM and Noon Tuesday. Snow levels will start off around 4,000′ Monday night and lower to about 2,500′ through Tuesday. Showers will remain in the area throughout the afternoon and evening. This storm will certainly be impacting travel Monday evening and Tuesday morning in Northern California. The heaviest snow should be to the West of Siskiyou Summit but conditions will still be hazardous on I5. The NWS has not yet issued an advisory for this system, but I suspect they will do so within the next 12 hours or so.
Southern Oregon will see showers from this system, just not as widespread as Siskiyou County. Snow levels will start around 3,000′ Monday evening and drop to about 2,500′ by Tuesday morning. Up to 1″ of snow could fall in the higher elevations of the Rogue Valley. The Cascades will see 1″-3″ of snow from this system, but to the East of the Cascades only 1″ of accumulation with snow levels slightly higher (starting off around 3,800′). The Coast is looking at anywhere from a half an inch of rain to three quarters of an inch.
This wet and cooler pattern is going to continue through the week. Wednesday we will see a slight break in the morning and early afternoon hours but by the evening the next system is on our doorstep. This system will again bring rain and snow with snow levels around 2,500′. Friday’s storm will bring a warm front through during midday, before then bringing a cold front in. Again, another system moves through Saturday so Friday evening into Saturday rain and snow are a possibility also.
