Tale of two seasons

The country is seeing two distinct weather systems

August 28, 2010 — Two different weather patterns are sweeping across Canada. Summer has a strong hold in the east, but in the central and western Prairies, it's all about the fall-like conditions.

In the east, it's heating up, and in the west, it's cooling down.

The central and western Prairies are feeling like fall. Edmonton hovered around the 13C mark on Saturday, while Calgary was around 16C.

The chilly conditions will sweep through Saskatchewan on Sunday. Temperatures are expected to dip to a cool 11C for Regina.

What is the driving force behind all the cool air? We've got a big upper trough in the jet stream and that's what's keeping both provinces cool. The northwesterly winds are making it feel like fall, explains Michelle Cassar, a meteorologist here at The Weather Network.

However, it's a totally different story for the east. From Manitoba all the way up through James Bay and even into the East Coast, the conditions are hot and humid.

We've got a big, huge ridge that's tracking through the eastern portion of the country. Additionally, there's a continental high over the eastern U.S. which is bringing stable, fair conditions with sunny skies and summertime weather, says Cassar.

Major cities like Winnipeg, Montreal and Halifax will all be feeling the muggy air and baking sun. In Toronto, the forecast is calling for seven straight days of sunshine and warm temperatures. As for the rain, there isn't much in sight in the long range forecast. In fact, many regions have a zero per cent P.O.P. for the next few days.
