March 2019 – Warmer with less snow

Irishtown Nature Park, Moncton, 31 Mar 2019 (Dearing)

March seemed quite cold overall in Southeast New Brunswick especially given some frigid overnight lows during the first ten days of the month.

Daytime highs improved dramatically after that culminating with a maximum of 16.8°C on the 31st.

Only two days recorded temperatures with both highs and lows above freezing.

The month was also dry with less than half of the normal rainfall and snowfall received.

Weather bomb crosses the continent

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.

Winter 2018-19 in Review

Winter 18-19
Wintry weather will undoubtedly continue in New Brunswick for the next few weeks but meteorological winter (December, January and February) is officially over.

In Greater Moncton, winter proved to be slightly colder than normal (0.3 degrees cooler) although the extreme low was not as cold as previous years.

Precipitation was about average for the season with slightly above normal rainfall and slightly below normal snowfall.

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.

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.

Coastal B.C. gets winter wallop

Wintry weather doesn’t visit the coast of British Columbia very often but it certainly causes disruption when it arrives.

Following back to back snow days, Vancouver has picked up almost 25 cm of snow with higher amounts in the Fraser Valley and Victoria has recorded more than 40 cm.

An Arctic outflow pushing temperatures below freezing combined with low pressure off Vancouver Island is creating snowy rather than more typical rainy conditions.

Traffic and transit services were snarled, schools were cancelled and scattered power outages kept crews busy in the region.

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.

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.

Snow falling in west end Moncton, 09 Jan 2019 (Dearing)

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.
