We’ve had a lengthy run of chilly temperatures to start the month of December. After a 24-hour surge of mild air during the first couple of days of the month, temperatures have been consistently below normal to kick off December…and in some cases have been quite chilly. Readings over the weekend averaged 10 to 15F degrees below average as highs were only in the upper 20s and lower 30s on Saturday and in the lower and middle 30s on Sunday. The average high for December 10th is 45F at Hyannis.
The theme of colder than normal weather will persist through most of the upcoming work week as temperatures will struggle to crack 40F through Thursday. And the period from Tuesday night into Thursday will once again be solidly below normal as a reinforcing shot of cold air builds into the area.
With the cold air bleeding southward on northerly winds, we’ll have a rather persistent deck of ocean effect cloud cover to contend with today, tomorrow and Wednesday. As cold air deepens over the region Tuesday night and Wednesday (and the northerly flow strengthens) that deck of ocean effect cloudiness will likely start to yield some flurries and snow showers. In fact, during the day on Wednesday and into Wednesday evening, it’s possible we see a few hours of steadier snow which could lead to a bit of minor accumulation.
Our first shot solid opportunity for widespread normal daytime temperatures won’t come until Friday.
