Alberta; Saskatchewan - After a long cool-down, and dull days (consistent cloud covers brought by troughs after troughs), finally sunny and hot days arrive!

A low pressure system situated near the coast of Queen Charlottes Island is tracking its way along the jet stream. To the east of this system, are warm, southerly, desert air from Arizona and parts of Texas in United States. This pushes the jet stream way to the north. It is forecasted that it is even possible for the jet stream to reach Beaufort Sea by Monday. Even Yellowknife, Northwest Territories may experience temperature as high as 11 C on Monday.

While this is good news for Alberta and Saskatchewan, it is, in fact, a bad piece of news for West Coasters. Heavy rain and winds are expected on the West Coast. Environment Canada had issued warnings to the locales earlier today.

Back to discussing the low pressure system. As the system advances towards the East, the warm air follows the low pressure system. The core of the warm air, has a high of 40 C in Texas! Right now, as of 17:09 MDT, Calgary experiences a temperature of 16 C; Edmonton experiences a temperature of 18 C. This is such a contrast to the previous snowfall on Thursday. Major snowmelt is expected, as the 23 cm of snow that had fallen on last Thursday melt under the warm 18 C and sunshine. Rivers can easily break its banks. For local residents, it is advised to move further up to higher grounds. It will continue be warm for Sunday in much of Alberta.

This system will continue advance to the East, and so will the warm air. By Monday, much of the heat will move into Saskatchewan, while Alberta is left with a cold front, cooling down the locale. By Tuesday, much of Alberta will cool down slightly back down to seasonal temperatures. Some non-severe thundershowers may be expected with the cold front. Meanwhile, Saskatchewan will be scorching in this summer's heat. According to the models, it looks as if the hot air mass' core will move as north as South Dakota. As a result, it is possible for Regina to reach 26 C as a daily high on Tuesday. For my personal forecast, I think the national warmest spot for Monday will be around Estevan in Saskatchewan, where the temperature might reach as high as 30 C (this is the extreme value, of course, the actual temperature for that day can be anywhere between 23 C to 30 C)!

By Tuesday, it is Manitoba's turn. This time, the heat's core moved back down south, and slightly weakened. As for Saskatchewan, once again, the temperature will return to slightly above average value (as opposite to way over average values). On Tuesday, Winnipeg can reach as high as 23 C (forecast calls for 20 C, but I think anywhere between 17 C to 23 C is possible).

By Wednesday, it will be Ontario's turn. Without any more description (I am sure you are bored with my descriptions), Toronto will reach 15 C, and warmer down towards Windsor, Sarnia, and London.
