A slow moving low pressure system brought a wintry mix of snow, ice pellets, freezing rain, rain and strong winds to Southern Ontario and Southern Quebec over the weekend.

Icy conditions led to more than 1,600 highway crashes, numerous power outages from falling trees and downed lines, cancelled flights, transit delays and school closures.

Officials were forced to close the CN Tower due to falling ice from the structure.

Winter storm

Whiteout conditions in the first of three winter storms, west end Moncton, 08 March 2018 (Dearing)

The first of three successive snow events dropped 15.3 cm and slight amounts of rain on Greater Moncton yesterday.

However, the intermission is a short one with Environment Canada issuing another snowfall warning for most of New Brunswick.

The next low pressure system arrives tonight and will persist into Saturday with flurries still possible on Sunday as the storm stalls in the Gulf of St. Lawrence.

Up to 25 cm could fall by the time it finally leaves the province and even more is expected in northern New Brunswick.

Monday is expected to be partly sunny before another system with more snow arrives on Tuesday.

1-2-3 Winter Punch Coming

After days of cloudy skies and mostly dry conditions, it seems Old Man Winter is returning.

While no weather warnings are currently in place for Southeast New Brunswick, snowfall advisories have been issued for areas to the north and west.

Environment Canada says a low pressure system approaching from the U.S. Northeast could bring 10-15 cm of snow Thursday with a changeover to rain by evening as temperatures climb above freezing.

But another storm system will move into the region late Friday and into Saturday with rain changing over to snow.

And early next week could bring yet another storm system.

Meteorological winter 2017/18 is now in the books since the three month period of December, January and February is over but we all know winter is not over yet in Southeast New Brunswick.

What a ride it has been in Greater Moncton with temperatures fluctuating wildly from very mild to extremely cold in just hours and in one case in mere minutes.

Snowfall was lighter compared to normal especially in February but the bigger concern were frequent periods of mixed, icy precipitation such as freezing rain and ice pellets.

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.

Rivers spill banks in SW Ontario

Days of rain, melting snow and ice jams have created swollen rivers and streams in Southwestern Ontario causing historic flooding.

A young boy was swept from his mother’s arms in a stranded vehicle along the Grand River near Orangeville and efforts to find him are still underway.

Streets, homes and businesses in low-lying areas of Chatham-Kent were flooded after officials say the Thames River peaked at 5.25 metres above normal Saturday.

Emergency responders had to rescue some residents by boat who were taken to a local convention centre for shelter.

Another flash freeze!

Environment Canada issued a flash freeze warning for much of New Brunswick, Nova Scotia and Prince Edward Island early today.

A low pressure system brought snow, later rain and then snow again after the temperature plummeted as Arctic air pushed back into the region.

The daytime high in Greater Moncton was 3.0 C at 11am and pooling water began freezing when the thermometer dropped below freezing by 3pm.

By early Saturday, forecasters say the low could drop to -20 C but temperatures will moderate on Sunday before falling again on Monday.
