Sharp drop in temperature!

Temperature contrast 8pm, 12 Nov 2019 (earth nullschool.net)

Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.

The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.

But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.

Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.

Deep snow cover across N.B.

This has been a very snowy winter across northern New Brunswick with Edmundston and Bas-Caraquet recording 114 cm of snow on the ground as of today (06 March).

Some unofficial reports have indicated a snow depth of more than 160 cm in some mountainous areas.

Southern New Brunswick also has plenty of snow but often it has been mixed with rain, freezing rain or ice pellets which have lowered accumulations.

Greater Moncton now sits at 53 cm (the most so far this season) and snowbanks are getting high enough to cause visibility issues at some intersections.

Second heaviest snowfall of the season

A low pressure system approached the Maritimes from the northeastern United States late Sunday night.

Snow began in New Brunswick early Monday and intensified throughout the day before tapering off to freezing drizzle by evening.

About 24 cm fell in Greater Moncton which was the second heaviest snowfall of the season after the storm on 13 February.

The system also brought snow to western and central Newfoundland later on Monday with freezing rain to the Avalon Peninsula.

Snowfall amounts (cm) as of 1AM Tuesday from Environment Canada:

  • Sydney: 26
  • Saint John Airport: 26
  • Greater Moncton Airport: 24
  • Deer Lake: 23
  • Fredericton: 21
  • Miramichi: 21
  • Charlottetown: 19
  • Greenwood: 19
  • Halifax Stanfield Airport: 17
  • Bathurst: 14
  • Gander: 14
  • Yarmouth: 12

Heaviest snowfall of 2019

Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.

A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.

Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.

Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.

Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.

January 2019 – Wet and wild!

The beginning of 2019 proved to be wild and crazy in New Brunswick.

Precipitation was well above normal for January as storm after storm brought rain, freezing rain, snow and ice pellets with rapidly fluctuating temperatures.

Ice and snow often blocked storm drains which created flooding during heavy rain and when the thermometer plunged, it all froze.

The average monthly temperature was actually about one degree above normal although it didn’t seem like it given the roller coaster of highs and lows.

Rain, freezing rain cause flooding

It’s been quite a week for stormy weather in New Brunswick.

The latest system brought heavy rain and a period of freezing rain to the province.

Ice-clogged storm drains caused the water to backup turning streets into rivers in areas such as downtown Moncton.

Municipalities were urging residents to help public works crews by trying to clear drains near their homes.

Mild temperatures contributed to snowmelt and the added rush of water was enough to washout some roads and bridges.

Strong winds along the coast also gusted to more than 100 km/h.

Rainfall amounts (mm):

  • Mechanic Settlement 68
  • Miramichi 61
  • Sussex area 55
  • Kouchibouguac 44
  • Fredericton 34
  • Saint John 25
  • Moncton 13

Major winter storm approaches

A strong winter storm will track across the Maritimes Sunday bringing a mixed bsg of precipitation to Southeast New Brunswick.

Snow at times heavy will begin in the morning changing to ice pellets and freezing rain by noon and eventually to rain later in the afternoon.

Greater Moncton is expecting about 20 cm snow, 20 mm of rain and possibly several hours of ice accumulation.

Strong winds will develop giving reduced visibility in blowing snow with gusts reaching 80 km/h along the Fundy coast.

Conditions may not improve until Monday afternoon as the storm moves eastward.

Risk of frostbite

A good old fashioned January cold snap continues in New Brunswick with well below normal temperatures since last weekend.

Wind chill values have dropped to -30 giving the risk of frostbite on exposed skin.

After a frosty -21.4°C in Greater Moncton earlier this week, forecasters say a further tumble to -23°C is likely before a potent winter storm arrives on Sunday.

Environment Canada is tracking a system moving across the U.S. which is expected to bring at least 30 cm of snow, 50 mm of rain, a period of freezing rain and strong winds to the Maritimes.

Winter storm stretches across central, eastern U.S.

A major winter storm brought heavy snow and mixed precipitation from the American Midwest to the mid-Atlantic states over the weekend.

The snow began falling in Kansas and Missouri with some areas getting almost 50 cm.

The storm knocked out power, disrupted air travel and created slippery highways with numerous collisions including an Illinois crash which killed a police officer.

Freezing rain led to a build-up of ice on surfaces in North Carolina and Virginia.

Between 15 and 30 cm of snow fell over the Washington, DC area – its heaviest snowfall in three years – which closed schools and federal government offices on Monday.

Forecasters say melting during the day would create hazardous black ice after sunset as temperatures fell back below freezing.

The storm system has moved out into the Atlantic but will brush Cape Breton Island and eastern Newfoundland on Tuesday.

Messy mix and a freeze!

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.
