Scattered frost!

Geranium with light frost damage in NE Moncton, 19 Sept 2019 (Dearing)

It was a cold morning in the Maritimes and frost advisories were posted for all three provinces.

Scattered frost was recorded in many areas including Greater Moncton where the thermometer fell to -0.4°C at the airport which is close to the 2008 record low of -1.2°C.

However, a minimum of -4.4°C was set in the area in 1945.

This was a light frost and much earlier than the average date of 04 October.

Chilly nights!

Last Zero
The last couple of nights have been chilly across New Brunswick with overnight lows in the low single digits.

While Greater Moncton fell to 5.5°C which was a few degrees away from the record, the same minimum in Bouctouche was cold enough to set a new low.

Edmundston dipped to a nippy 1.1°C which tied its record as did Grand Manan when it dropped to 3.8°C.

Over the last six years in Greater Moncton, the chart above shows temperatures have not fallen to the freezing point or lower after early June.

Finally above freezing!

For the first time in 12 days, the daytime high in Greater Moncton finally climbed above freezing with a balmy high of 1°C today!

The normal maximum for early March in Southeast New Brunswick is 2°C with a minimum of -8°C.

The last third of winter has been especially cold with overnights consistently below -10°C and even as low as -20.1°C early Friday.

However, there is some good news – Environment Canada is forecasting that the next five out of six days will have highs above freezing.

Unbelievable cold in the West!

COLD

An Arctic air mass has plunged much of Western Canada into the deep freeze with the coldest weather in nearly a decade.

Frigid temperatures have broken records in Saskatchewan, Alberta and British Columbia with the wind chill making it feel more like -50 in some areas!

Emergency responders had many calls related to frostbite and hypothermia with seniors and young children being especially vulnerable to the cold.

Auto clubs had almost ten times as many requests from drivers for dead car batteries.

The first half of February in Southeast New Brunswick was decidedly winter with frigid overnight lows dropping to a numbing -21 C in the first few days alone.

But the second half of the month was spring-like with most daytime highs above freezing and more tolerable minimums.

The average monthly temperature for Greater Moncton was about 3.2 degrees above normal and anything above 2 degrees is considered significant in meteorology.

Precipitation was slightly above average with more rain than snow falling compared to normal.

Near record cold in N.B.

The last couple of days had near record lows in Greater Moncton with temperatures dropping to near the freezing point.

A low of 1.0 C at the airport on Monday was close to the 1947 record of 0.6 C while a low of 0.0 C on Tuesday tied the minimum from 1995.

Fortunately cloud cover prevented frost in most of New Brunswick but another risk is possible by early Wednesday.

Folklore suggests frost can be expected until the full moon in June which is this Friday the ninth.
