Wintry mix for New Year’s Eve

A wintry mix falls in NE Moncton, 31 Dec 2019 (Dearing)

The same storm system which impacted Ontario and Quebec is now creating travel havoc in the Maritimes with a mixed bag of precipitation.

Snow along with ice pellets began in Southwest New Brunswick on New Year’s Eve morning and gradually spread to Greater Moncton by early afternoon.

About 14 cm of snow and ice pellets could accumulate in the Southeast before a changeover to rain around midnight as temperatures rise above freezing.

Snowfall warnings have been posted in western and northern New Brunswick with 15 to 30 cm likely with lesser amounts for Prince Edward Island and mostly rain is forecast for mainland Nova Scotia.

UPDATE

Moncton received 5.4 cm of snow, Saint John had 3.4 cm while about 10 cm fell in Fredericton but near 30 cm in Woodstock.

Messy mix falls over Maritimes

After exiting Ontario, a Colorado Low moved into the Maritimes bringing freezing rain and rain to Nova Scotia along with mixed precipitation to Southeast New Brunswick.

The system shut down schools in many parts of the region on Tuesday with icy roads being a major factor.

Greater Moncton had several hours of freezing rain and ice pellets mixing with snow (3 cm) and later rain (15 mm) as the temperature climbed slightly above freezing.

Northern and western New Brunswick received mostly snow with 10 cm in Fredericton, 18 cm in Miramichi and 27 cm in Woodstock.

November 2019 – Colder and snowier

November got off to a mild start in Greater Moncton – the monthly high 19.4 C was actually 0.1 degrees warmer than October’s maximum – but temperatures quickly tumbled especially overnight.

Only two nights were actually above freezing with the coldest weather around the middle of the month.

The first measurable snow was recorded on 07-8 (18.8 cm) which was more than half of the November total and rainfall was lighter than usual.

Daytime highs struggled to climb above freezing especially during the last two weeks which led to a below normal monthly average.

After taking a look at the past seven growing seasons in Greater Moncton including 2019, the last freezing temperature in Greater Moncton in the spring has been recorded from a month-long period from early May to early June.

Meantime in the fall, the first freezing temperature has been recorded from a month-long period from mid-September to mid-October.

Warmest since early November!

The last day of March proved to be the warmest day in Greater Moncton since 03 November when the thermometer hit 17.1 C.

The daytime high reached a balmy 16.8 C and the New Brunswick hot spot was 19 C in Sussex which brought residents outdoors to walk, run, hike and play.

The maximum was actually close to the record for the date which was 17.5 C from 2006.

But a passing cold front will drop the temperature considerably overnight as rain changes to snow and Monday’s high struggles to reach slightly above freezing.

Spring arrives early in the North

A warm air mass has surged into Western Canada this week bringing record temperatures to the region and also to the North.

Many communities from Yukon to Nunavut were well above freezing and into the double digits breaking March records.

Yohin Lake hit a record high of 18.8°C Monday and spiked to 20.2°C Tuesday marking the first time in March the thermometer has climbed above 20°C in Northwest Territories.

Daytime highs in British Columbia’s Fraser Valley hit the mid 20’s while Alberta residents enjoyed maximums in the high teens.

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.

1-2-3 New Year Punch

For the third time since the start of 2019, Southeast New Brunswick was hit with snow.

Another low pressure system initially brought snow with 21 cm recorded in Greater Moncton following briefly by ice pellets and then 5 mm of rain as the temperature climbed above freezing.

Higher amounts of snow fell in central and northern New Brunswick while more rain fell over mainland Nova Scotia with localized flooding in the Halifax region.

Environment Canada expects calmer but colder conditions over the next few days.

Messy mix and a freeze!

Icy conditions at Cap-Pele Harbour, 29 Dec 2018 (Dearing)

A low pressure system from Quebec moved across New Brunswick Friday and into Saturday bringing a mixed bag of precipitation.

Snow began in Greater Moncton by late afternoon which later changed to ice pellets and then freezing rain followed by rain as the temperature climbed above freezing.

After 9 cm snow, 2.5 hours freezing rain and about 7 mm rain, some of the snow melted but by early evening, the thermometer dropped below freezing again which led to ice.

While this may be the last major weather event of 2018, Environment Canada is forecasting another system bringing snow or rain for New Year’s Day.

Bitter cold hangs on

An Arctic air mass continues to have its grip over the Maritimes with today marking the sixth day of below freezing temperatures in Greater Moncton.

The early morning lows dropped to -16.1°C yesterday and -16.5°C today.

Brisk northwest winds have also created bitter wind chills into the -20s this weekend giving a risk of frostbite on exposed skin.

The normal high for early December is 0°C and the low is -8°C.

Environment Canada says temperatures may not climb above freezing until Friday making this one of the longest cold snaps in recent memory.
