Record setting cold is on the way mid-week. Overnight lows in the mid-20s and daytime highs hovering around freezing Wednesday will make this week feel more like January than mid-November. Luckily, this bitter cold snap will be short-lived, with temperatures rebounding back into the 50s by the end of the week.
Rest of today – temperatures will be falling through the 40s during the day. Precipitation should end as an Arctic front pushes through. Temperatures will continue dropping into the 30s throughout the evening and bottoming out in the mid-20s. Precipitation should end before it gets cold enough to produce snow. Winds will become stiff with the parent low strengthening and a tight pressure gradient forming between that and an incoming high pressure center.
Wednesday – sunny with record low high temperatures in the low-30s as a frigid Arctic air mass takes hold. Overnight lows continue to be cold, in the upper-20s.
Thursday – temperatures start to rebound into the upper-40s as a warm front approaches and we enter the warm sector of the next storm. Return flow around the western edge of the high pressure exiting east will also assist in helping move some warmer air in. Overnight lows in the mid-30s.
