Our first round of valley rain and mountain snow has passed over northern California. Isolated thunderstorms have been bubbling up over the valley, and a second round of valley rain and mountain snow arrives tonight and Wednesday morning. The unsettled weather pattern which began the last week of January continues on this second day of February in northern California. Isolated showers and thunderstorms have been popping up over Shasta and Tehama counties, but they will disappear after sunset. We can expect brief clearing tonight before more clouds roll in from the northwest Wednesday morning, and we'll have the best chance for valley rain and mountain snow late tonight through early Wednesday afternoon.
As the second disturbance quickly exits California late Wednesday afternoon and evening, we can expect a rapid clearing of our sky late Wednesday night with more sunshine and a gradual warming trend into the weekend. We can expect a mostly sunny to sunny sky Thursday through Sunday, with temperatures rising to above average levels. A small Pacific storm will approach California late Sunday, and at this time it appears it will move northern California early next week. There is a slight chance for light rain and snow showers, but it is more likely that we'll get more clouds than actual precipitation. Mountain highs will rise from the 30s into the 40s and lower 50s, while valley highs will rise out of the 50s and into the mid 60s.
