And we're back, to normal late-December temperatures. A cold front swept through the city last night, putting an end to the unseasonably mild weather. The last six days were more than fourteen degrees warmer than normal, and this was the first time since January 2013 that Central Park has had six consecutive days where the temperature was at least ten degrees above average. Despite the cold front's passage this afternoon's high will reach the lower 40s, which is slightly above average for the end of December.

Colder air will be here by tomorrow as a cold Canadian air mass slowly moves in. Highs tomorrow and Wednesday will only reach the mid 30s under mostly sunny skies. It is likely to be below freezing when the big ball drops on New Year's Eve but, unlike Las Vegas, we won't see any snow.

The new year will start with another cool day on Thursday, but we should see some warming as we head into the weekend. Friday's high should reach the upper 30s and we should be somewhere in the 40s, albeit with the possibility of rain, on Saturday and Sunday. The passage of that weekend storm should bring on another cold outbreak next week.
