October 3, 2010 — The jet stream has divided the country up into two completely different weather systems. Depending on what part of the country you live in, you could either be experiencing warm, seasonal conditions or chilly and possibly wet weather.

Fall is here, but if you're in the western part of Canada, it hasn't exactly been feeling that way.

All across British Columbia, Alberta and Saskatchewan, temperatures have been warm with dry conditions. In fact, Vancouver residents took advantage of the weather by spending the day at the beach and playing volleyball seaside on Friday.

It was so warm, temperature records were broken. Creston peaked at 24.7C and West Vancouver hit 22.8C. And then on Saturday, Milk River, Alberta was the country's hot spot at 28.6C. It's all because of the ridge in the jet stream, and warm air is being pulled up from the south, explains The Weather Network's Dayna Vettese, a meteorologist.

Weather across the Prairies has also been unseasonably warm. Earlier this week, parts of Saskatchewan hovered around the 30 degree mark.

The west may be warm, but the same can't be said for the central and eastern parts of the country. Manitoba, Ontario and Quebec are all below seasonal because of the trough in the jet. Cold, arctic air is being pulled down from the north into eastern Canada. With the arctic high settling over Ontario, temperatures around the Great Lakes are around five to six degrees below seasonal. Earlier Saturday morning, some areas were also reporting snow flurries including Timmins and Kapuskasing.

As for Quebec, the cooler weekend air is a complete turnaround from Friday's record-breaking temperatures. Gaspe jumped to a warm 24.9C while Riviere-la-Madelaine reached 24.5C. Meanwhile for Saturday, Montreal and Quebec City are forecasting a high of 11C with overnight temperatures dipping down to the single digits.

The Maritimes is a different story altogether. Areas of low pressure have been tracking up the eastern seaboard bringing a southerly flow, explains Michelle Cassar, another meteorologist here at The Weather Network. For the second time this week, Ingonish, N.S. was the hottest spot across the country on Friday. Other cities that broke records were Greenwood at 27.1C, Halifax at 23.8C and Syndey at 22.3C.

Meanwhile, several cities across Newfoundland heated up as well. On Saturday, Deer Lake peaked at 26.4C and on Sunday, Badger climbed to 24.4C. Places like Corner Brook, La Scie and Rocky Harbour also broke records as they hovered in the mid 20's over the weekend.

However, all good things must come to an end. It's the last day of warm weather for the East Coast. A cold front is tracking through, which will essentially snap temperatures back to seasonal. In addition to the mercury drop, there's also a frost warning in place for parts of New Brunswick on Saturday evening.
