A trough has set up off shore dipping down to central California bringing arctic air to the region, cold enough to bring snow! Snow accumulation on roadways has already been seen this morning and will be impacting roads during this event that will last for the next several days. Roadways being impacted by snow and ice included I-5, HWY 97 and HWY 140 while other roadways can be impacted by low visibility and ponding of water from rain. If you’re traveling in northern California, in the mountains or east of the Cascades you may want to carry chains. By the end of the event we could see 8-14″ of rain at higher elevations and 2-4″ a day at lower elevations. Chance for snow east of the Cascades and in northern California continue for some areas into early afternoon and returns again tonight, areas in Josephine county could even see snow as we head into tonight and especially valleys in northern California; Mt. Shasta City could see 2-4″ of snow.
Besides snow the chance for thunderstorms at the coast will last throughout the day and inland areas could see some lightning in the afternoon. In thunderstorms locally heavy rain, strong winds and small hail are possible. Remember if you hear thunder roar, head indoors.
Have a great day and remember to stay safe out there.
