Easter long weekend: What will the weather be like?
Tuesday, April 15, 2014, 7:57
After a rough start to the week, many Canadians may be looking for a reprieve during the upcoming long weekend. This week Mother Nature has a taste of winter in store for many of us, with daytime highs expected to be slightly above the zero degree mark for many in Ontario and Quebec by mid-week. In fact, on Tuesday, some communities in eastern Ontario and Quebec may be lucky enough to start their day with a thunderstorm, and end the day off with snow. Meanwhile parts of Manitoba and Saskatchewan shiver with single digit highs on the other side of the zero degree line. The good news is the weekend is looking a lot less volatile.
Here’s a look at the forecast:
From the Great Lakes east to Newfoundland, Friday is looking like a great day to head outdoors. With a ridge of high pressure in place from Quebec to Atlantic Canada the forecast calls for a mix of sun and cloud and seasonal temperatures across the board. The exception may be communities along the Superior shorelines where rain and possibly some mixed precipitation is not out of the question.
Central Saskatchewan and east towards Manitoba and northwestern Ontario look to also have a fairly dry day in store with daytime highs inching up above the zero degree mark just in the nick of time. Although for this time of year temperatures will be a little chilly, a substantial warm-up is expected between Thursday and Friday.
British Columbia looks to have some lingering precipitation in store for Friday with some coastal showers earlier in the day before drying off through the afternoon. The interior is also likely to see showers, with snow in the higher elevations. This produce showers throughout Alberta as well, but the start of the day looks to be a dry one. Across the region temperatures are also expected to be seasonal, so a fairly pleasant day is in store.
Eastern Alberta and western Saskatchewan however, should watch out Friday night, with temperatures dropping through the evening. Expect some of the rain showers to change into snow.
On Saturday a system is set to move into southern Ontario, bringing cloud cover and passing showers for a portion of the day. Temperatures may drop slightly as a result of all the cloud cover, however most regions should remain in the seasonal range.
The rain will likely make its way to Quebec mid-day and then track east along the St. Lawrence eventually reaching the Maritimes late Saturday or alternatively Sunday morning. There is some disagreement with regards to the forecast for the Maritimes however, as some models have started to move the precipitation into Nova Scotia earlier on Saturday. Even if this does happen the precipitation would be light to start, and initially New Brunswick, Prince Edward Island and Newfoundland would be largely spared until Sunday. The image below representing rain in the green and snow in the blue, highlights that Saturday afternoon parts of Quebec and New Brunswick may still be dry while parts of Ontario and Nova Scotia see rain.
In the west the forecast is a little bit more uncertain as weather models are disagreeing on the track of the system lying over eastern Alberta and Saskatchewan. Some models weaken the low and then move it out of the region, pushing it state-side. This would provide Saskatchewan and Manitoba with a mainly dry day, except for the possibility of some lingering moisture along the international border. The alternative to this forecast however is that the low pressure system heads east across the Canadian Prairies bringing moisture to Saskatchewan Friday overnight into Saturday, and subsequently Manitoba and northwestern Ontario Saturday through Sunday morning. This precipitation has the potential to be both rain and accumulating snow along with some gusty winds.
Along the B.C. coast there is an incoming system which will bring rain and gusty winds to the south coast likely later in the day rather than earlier. This system is the start of a showery weekend ahead for the province.
