| A powerful winter storm impacting the Pacific Northwest will drench Northern California with an atmospheric river before weakening as moves south through the area this weekend. Fair and warmer for Thursday and Friday as daytime temperatures top out around 60 degrees, while overnight lows cool to the 20's. Winds mostly from the west around 5-15 mph at times. Cool and unsettled weather is forecast to arrive this weekend as a new storm moves through Southern California. Clouds and winds will increase throughout the day on Saturday as highs cool to the lower 50's, southwest winds gusting to around 25 mph during the afternoon. Showers will develop Saturday night with rain likely on Sunday, windy with west winds gusting to 30 mph. Atmospheric rivers are inherently warmer, so as usual the snow level may start out at or above 8,000 feet, falling to around 6,000-7,000 feet by Sunday night or Monday. Highs will cool to the 40's as overnight lows remain in the 20's. Preliminary rainfall amounts of around a quarter to half inch are possible with a few inches of snow, mainly above 7,000 feet. Showers will taper off on Monday ahead of another storm that could impact the region Tuesday or Wednesday of next week. If you have travel plans into the mountains for opening weekend at Snow Summit, be prepared and carry tire chains. Weather conditions can change rapidly in the mountains and traveling could become treacherous on Sunday!
