The animation below illustrates the Futurecast Temperature Anomaly for the week ahead, through Sunday, January 18.
Just as temperatures moderate to near-average territory mid-week, another blast of Arctic air will arrive Thursday morning that will bring the coldest air of the season!
Morning lows will drop into the upper teens to low 20s Friday morning, so we will need to mind the 4-Ps through the end of the week.

The reality is that we are looking at a potential weather event one week away, and as such, there are too many variables that will change between now and then.
Below is the timeline as to when to expect certain details within a winter weather forecast:
Stay tuned, but don’t buy all the milk, eggs, or bread just yet!
