Canada's newest tropical destination: Hudson Bay

Tuesday, June 12, 2018, 7:27 AM - Hudson Bay isn't known to be a tropical destination, but this second week of June has featured stifling temperatures near the 60th parallel. How warm did it get, and more importantly why? Read on:

HEAT WAVE HIGHLIGHTS

  • On Sunday, Churchill, Manitoba shattered the daily record by 5°C to nearly 30°C
  • Monday's new record even warmer at 32.2°C, smashing the previous record of 24.4°C set back in 1950
  • It won't last – highs plummet back to the single digits by Wednesday

Well, as the Maritimes struggle to find even some resemblance of summer weather, a relatively narrow wedge of air from the Gulf of Mexico tracked into northern Manitoba and northwestern Ontario Sunday and Monday. The severe weather threat in the Prairies this past weekend developed a strong upper trough, while a fairly robust high pressure system near the Ontario and Quebec border enhanced the mild southeast flow across the region.

THE PATTERN



Something stand out below? This was the forecast for Monday, the most beautiful, tropical weather in the country is nestled along the shores of Hudson Bay. But shouldn't the chilly waters buffer and protect Churchill? Not in this case.

Strong southeast winds are downsloping towards the shores of Hudson Bay, so there's no influence from the chilly waters (think, low single digit water temperatures). As air descends, it has the ability to dry and warm as it is brought down towards sea level. And, in case you were wondering, water temperatures for reference remain in the single digits all year round in Hudson Bay – so I can't recommend swimming.

NATIONAL HOT SPOT...CHURCHILL? ALSO WARMER THAN FLORIDA?

Yeah, that's a little unusual for the national hot spot on Monday to be Churchill, the warmest place in the country!

But, will this pattern last?

No, it is only June after all, and this pattern was definitely an exception. Look where temperatures end up falling to by Wednesday

LONG RANGE TEASER

What's the deal with the second half of the month? 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. 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. 

Remember our summer forecast? That trough will play a pivotal piece of the puzzle of the next couple of months...
