Atl. Canada's soggy system drags temps well below normal

Thursday, June 14, 2018, 8:14 AM - Just as much of Atlantic Canada set new record LOW temperatures earlier this week, another miserable system is dumping heavy rain AND snow on the region. Temperatures are about 10 degrees cooler than normal as well. More on the brief improvements, below.

WEATHER HIGHLIGHTS:

  • Incoming system brings 20-30 mm of rain to Maritimes through Thursday
  • Newfoundland sees the rain Thursday-Friday with chilly single digit temperatures as well
  • Chance of some flurries for parts of coastal Labrador through end of week

As several parts of the country have already been thrust into mid-summer like heat (including Hudson Bay!), Atlantic Canadians struggle to find any resemblance of summer weather on the horizon.

WIDESPREAD RECORD LOW TEMPERATURES

On Monday, widespread record low temperatures were set right across Atlantic Canada with several places even dipping below the freezing mark, smashing some pretty long withstanding previous records. 

Edmunston, New Brunswick for example dipped to -1.7°C on Monday, beating the old record of -0.6°C set back in 1923. 

More record lows fell across Labrador on Wednesday with Hopedale and Nain both beating 30+ year record cold temperatures. 

HEAVY RAIN SPREADS ACROSS THE MARITIMES

The bulk of the system responsible for Thursday's rain, which also brought severe weather to Ontario on Wednesday, is pulling north through eastern Canada. While widespread rainfall is expected as the tail end of the system droops through the region, we don't expect much - if anything - in the way of thunderstorms.

A secondary low pressure centre is expected to spin up over the Maritimes through the day on Thursday, prolonging the rain and unsettled conditions through the day. Once this low moves past and off into the Atlantic, some wrap-around colder air may bring flurries back, once again, to parts of Labrador.

Between 15-30 mm of rain is expected in southern New Brunswick with about 10 mm likely in Nova Scotia. And with the system sliding a little more to south, this means cooler air across much of the east with temperatures about 10 degrees colder than seasonal.

HIGHEST TIDES OF THE YEAR

Environment Canada issued a special weather statement for Nova Scotia's Digby, Shelburne and Yarmouth Counties for "one of the highest tides this year."

"This combined with weak storm surge will bring higher than normal water levels, but is not expected to pose a significant flood threat at this time," says EC in the statement.



BETTER WEEKEND FOR THE MARITIMES, STILL COOL IN NEWFOUNDLAND

The good news is things are looking up for the weekend. As high pressure builds, dry weather moves back in with milder temperatures finally spreading into the region, though still rather chilly for Newfoundland. An active and unsettled pattern looks to return early next week, but temperatures will be closer to seasonal values at times.

"We're keeping a close eye on some substantial heat for the Pacific Northwest (including B.C and Alberta), and also eastern Canada early next week," says Weather Network meteorologist Tyler Hamilton. "Some of this heat will also spill into Atlantic Canada, as well, but, the eastern Canada warmth will likely not be prolonged as a trough will help balance out the second half of the month in terms of temperature anomalies."
