A warm front will bring an initial push of precipitation and light snow at higher elevations. A cutoff low will follow, with a converging moisture flux which brought broader precipitation to areas of Del Norte and Humboldt in the following days. A colder air mass approaches in succession of the previously mentioned, bringing 500mb temperature of -27 to -29 Celsius, increasing instability over the weekend.
