Check out all the frigid air in Canada! These are the 9 PM temps Monday. The real winter chill has remained out of the U.S. for most of this winter and there won’t be any big changes as February ends. We’ll turn warmer this week with highs well into the 70s. A little shot of cool air returns this weekend, but our chances of seeing another frost this season, let alone a freeze, are diminishing by the day.
