The extraordinary run of warm weather has come to an end. The six straight days of 60+ temperatures falls one day short of 1998's record of most consecutive days reaching 60 degrees in December. The last three days also either set or tied Central Park's all-time record for that day, something that has not happened since May 2001. We'll get to experience normal December temperatures this weekend—but don't blink, as another bout of unusually warm weather is coming next week.
It's kind of crazy: even though it felt chilly out this morning, the low of 46 is three degrees warmer than the normal high for December 16th. Thanks to a northerly breeze, for much of the day the temperature is going to hold steady, only reaching 50 or so this afternoon.
Tonight we'll get hit with a classic late-fall/early-winter storm where the massive low pressure system that is pulverizing the Rockies and Midwest passing over the Great Lakes has enough energy to produce a weak coastal storm. That secondary storm will make for a rainy Thursday. The warm weather will make a brief return as tomorrow's high is expected to reach the upper 50s. Friday is looking like a mixed bag with some sun and clouds, a slight chance of showers, and a high hovering around 50 degrees.
Near normal temperatures arrive for the first time this month on Saturday behind a cold front passage. Look for the high to only reach the lower 40s. Sunday should be a couple of degrees warmer and that will be it for seasonable temperatures this year. Temperatures will rebound to the 50s on Monday and will be back to record, or at least near-record, levels in the mid to upper 60s from Wednesday through Sunday. Merry Christmas!
