Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.
Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.
However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.
About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

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.

The massive system began on the West Coast as a bomb cyclone bringing wind gusts up to 160 km/h and heavy amounts of snow in the mountains.
Strong winds accompanied by a mixture of rain, freezing rain, ice pellets and snow fell from the Great Plains to the Midwest and into the Northeastern U.S.

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.
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.

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.

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.
