This morning several records were broken with a new overnight low record in Redding of 29 degrees and Red Bluff's new record at 30 degrees. This afternoon is another mild, slightly below average day as far as temperatures are concerned with mostly sunny skies. Tonight we'll cool into the 30s in the valley but most will avoid freezing again.
Tomorrow expect increasing clouds through the day ahead of an approaching winter storm.
The next could drop more snow in the mountains down to 4000 feet in elevation. Rain will also be possible in the foothills. As far as valley rain amount, it could be anywhere from just a trace to half an inch. But better than nothing. I do believe it will trend toward the dry side of that, though. Rain & snow will be possible around midnight on Friday. With the best rain chances late Friday into Saturday.
Sunday and Monday should be mostly quiet, although showers possible in Siskiyou, Trinity, Modoc, and Northern Shasta counties on these days. Otherwise, partly cloudy skies prevail.
Another winter system could be here by Tuesday and Wednesday, bringing more rain & snow and keeping temperatures cool.
