Bomb cyclone

A so-called bomb cyclone brought blizzard conditions to Colorado and now heavy rain,  flooding and even tornadoes to the U.S. Midwest.

The weather bomb occurs when there is a rapid drop in atmospheric pressure over a 24 hour period.

Further north, the storm is dumping snow across Minnesota as it moves into northwestern Ontario.

Severe thunderstorm watches have been posted for Southern Ontario with strong winds expected along with heavy rain.

New Brunswick will the effects this weekend with significant rainfall and gusty winds in the forecast.

February 2019 – Cold & Stormy

February may be the shortest month but it certainly seemed a lot longer this year with bitterly cold and stormy conditions.

While January was snowy in Greater Moncton, all was quiet until the largest single snowfall of the year arrived at mid-month.

After several freeze-thaw cycles which produced icy conditions, the latter half became decidedly colder with bitter overnight lows and wind chills.

Strong winds and blowing snow created dangerous whiteout conditions during the last week wreaking havoc with transportation across New Brunswick.

Dangerous whiteout conditions across N.B.

Open areas like West Main Street were prone to drifting snow, 26 Feb 2019 (Dearing)

Strong winds created blowing and drifting snow across New Brunswick today which caused whiteout conditions on highways.

RCMP say a multi-vehicle pileup on Highway 11 near Cocagne late this morning involved 15 vehicles in a series of collisions.

Visibility was poor in whiteouts near the Cocagne Bridge.

The highway was closed as emergency responders cleared the wreckage and waited for the weather to improve.

Winds gusted as high as 85 km/h in Greater Moncton which created a bitterly cold wind chill giving a risk of frostbite on exposed skin.

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.

Frigid air follows ice storm

Southern New Brunswick received several hours of freezing rain Friday morning – enough to make highways and other surfaces extremely icy.

Schools were cancelled, many businesses delayed opening until midday, pedestrians were forced to walk like penguins and even salt trucks slid off the road in Nova Scotia.

Ice coated my own steps to the point where I had to slide down them and crawl to my car which was a few metres away.

Greater Moncton only received about 10 mm of rain but the water eventually froze when a cold front followed the ice storm and temperatures plummeted by early Saturday.

Winds were also strong behind the system gusting at times up to 90 km/h.

Environment Canada is forecasting colder than normal weather but mostly clear skies over the next few days.

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.

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.

Snow ushers in new year

About 12 cm snow fell in Moncton on New Year’s Day, 01 Jan 2019 (Dearing)

New Year’s Eve celebrations were just getting started in Greater Moncton when snow flurries began falling from the latest low pressure system moving through the region.

By the time the snow stopped late this afternoon about 12 cm had fallen in Southeast New Brunswick with higher amounts toward the north and east.

Rain had been expected but the temperature never climbed above freezing as forecast.

In the wake of the storm, strong northwesterly winds will usher in frigid air creating windchill values near minus 30 and a risk of frostbite.

Storm ravaged B.C. to get more active weather

Almost 7,000 customers are still without electricity in British Columbia after the most powerful windstorm in 20 years struck the province a week ago.

BC Hydro says most of the remaining outages are in the southern Gulf Islands and those customers should be back on the grid by New Year’s Eve.

At the storm’s peak about 700,000 customers were in the dark after wind gusts of between 90 and 123 km/h were recorded on Vancouver Island and the Lower Mainland.

After a brief quiet period over Christmas, the next system is coming this weekend bringing more active weather including rain, snow, and gusty winds.
