We have had a very mild month so far here in November with 18 of the 24 days averaging warmer than normal. We will continue that pattern both today and tomorrow before we trend to below normal temperatures to close out November and start December. Rain chances increase toward tomorrow morning but end by afternoon. More rain arrives Thanksgiving morning and should last into Friday morning. The coldest air so far this season arrives for the weekend and high temperatures may struggle to get much above freezing in some spots.
It's going to be arctic cold here thanks to the ridge, I don't think melting of whatever we may have will be an issue. Lack of new snowfall is a bigger issue, which you also alluded to.
