Snow falling in west end Moncton, 10 Nov 2017 (Dearing)
A low pressure system moved into New Brunswick today bringing heavy rain accompanied by a vigorous cold front with Arctic air behind it.
As a result, the temperature in Greater Moncton plunged dramatically in just one hour – from a daytime high of 10.3 C at 11am to only 1.8 C by noon.
The thermometer continued to drop below freezing and rain turned to snow before the sky cleared in the late afternoon.
Environment Canada is forecasting a cold but dry weekend with sunshine and temperatures at or slightly above freezing.

Autumn has made an abrupt return to Southeast New Brunswick.
The passage of a cold front lowered daytime highs in Greater Moncton from a near record of 19.3 C to a below seasonal high of 5.2 C over the past 24 hours.
Temperatures are poised to drop even lower later this week when the first blast of Arctic air this season moves into the Maritimes.
Environment Canada is forecasting a low of -7 C by early Saturday which will likely mean a hard, killing frost for any remaining sensitive vegetation.

The temperature climbed to 30 C for three days in a row in Greater Moncton which is an unofficial heat wave since 32 C is the maximum by definition.
Those warm daytime highs, 30.4 C (19 July), 30.4 C (20 July) and 30.0 C (21 July), still haven’t eclipsed the season-to-date maximum of 30.8 C recorded on 11 June.
A cold front moved west to east through New Brunswick yesterday triggering scattered thunderstorms with heavy rain, gusty winds and even hail.
The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

Environment Canada has issued a special weather statement for Southern New Brunswick over the potential for significant rainfall starting mid-week.
A slow moving cold front will approach the Maritimes Tuesday night and could draw in tropical moisture from a system off the Eastern Seaboard.
Rain would begin by Wednesday afternoon with heavy downpours possible by early Thursday.
Forecasters say there is still uncertainty but long range models suggest 100 mm or more for the event.

Southeast New Brunswick has experienced a dramatic temperature swing over the past 24 hours thanks to a double-barreled weather system which moved into the Maritimes.

After a brief clearing around midday, a cold front moved in and the temperature fell below freezing by early evening.
Forecasters say the region will experience below normal readings up until this weekend with another system bringing a mixed bag of precipitation by Friday.
