We’ll pass the midpoint of January this week, and it’s likely that we’ll have done so without any measurable snow or extreme cold. High temperatures this week are mostly in the 40s, perhaps touching 50 a couple of times midweek. Some cooler air may arrive on Friday or at the beginning of the weekend when we can’t rule out a shower.
