After a low pressure system brought heavy rain and strong winds gusting up to 74 km/h to Southeast New Brunswick early today, a cold front moved through the region plummeting temperatures below freezing.
The thermometer in Greater Moncton dropped an incredible 14 degrees in just one hour – from 15 C at 11am to 1 C at noon – and then fell below zero shortly afterward.
Today’s daytime high of 16.7 C has unofficially broken the 13 January record of 12.2 C from 1972.

The puddles of rain became covered in ice this afternoon in Greater Moncton as the temperature took a dramatic tumble during a flash freeze.
The thermometer peaked at 9.0 C by 11am before dropping like a thud to 2.0 C by 2pm and falling below freezing by 5pm.
The extreme cold will be short-lived as Environment Canada is forecasting a snow event on Wednesday with up to 20 cm possible.

Although much less snow has fallen in Southeast New Brunswick this winter compared to last, the region has still had its fair share of cold and numerous flash-freeze periods.
Arctic air gripped the region over the weekend and yesterday the early morning low fell to -20.1 C at the Greater Moncton Airport – the coldest so far this season.
But temperatures elsewhere were even colder, dropping to -33.4 C at Edmundston, -30.3 C at St. Leonard and even -25.5 C at the Saint John Airport.
The cold will not last with rain and milder air on the way by Tuesday.
