A weak disturbance has moved over northern California today, but all it was able to bring was some high cloudiness and stronger breezes. We'll lose most of those clouds tonight, but many more clouds are coming our way. Tonight we can expect decreasing clouds and another seasonably chilly night with lows ranging from the 10s and 20s in the mountains to the 30s and 40s in the valley and foothills. Thursday will be a mostly sunny and mild day with the breezes continuing. There will be a slight chance for showers over our northwest mountains, but little rain and snow will fall. Highs on Thursday will range from the 40s and lower 50s in the mountains to the upper 50s and lower to mid 60s in the foothills and the valley.
Friday will begin fairly quiet, but it will also be the day our weather pattern begins to change. We can expect increasing clouds with a chance for valley rain and mountain snow in the north and west by late in the day, and temperatures will cool significantly. A Pacific storm will then bring much better chances for valley rain and mountain snow on Saturday and Sunday. Lingering showers are still possible Monday, but most of the rain and snow will have fallen. After a brief, breezy break late Monday and Tuesday, another slight chance for showers arrives late Tuesday and Wednesday. Highs will finally fall to more seasonable levels, with 30s and 40s in the mountains, along with 50s and lower 60s in the valley and foothills.
