December 2016 -Weather rollercoaster


A cold late afternoon in downtown Moncton, 16 Dec 2016 (Facebook)

So many ups and downs occurred during December in Southeast New Brunswick, one might say we were riding a weather rollercoaster.

Early on 17 December in Greater Moncton, the thermometer fell to a monthly (and almost record) low of -22.1 C which then rose to a monthly high of 10.6 C only 36 hours later before eventually dropping again to -18.6 by late on 19 December.

Although many nights were extremely cold (eight below -15 C), daytime highs were often slightly above or below freezing which overall led to a slightly below average monthly temperature.

Most snow fell during the first half of the month (three snowfalls were 12 cm or higher) and although rainfall was below normal, overall precipitation was about average.
