Forecast – for Sep. 8, 2011

Last week’s forecast turned out pretty much as expected, with the only exception being that it was slightly cooler than forecast over the weekend. Luckily, the start of this forecast period is playing out toward the warm end of the weather models. These weather models were having a hard time trying to figure out what was going to happen this week, as they kept switching back and forth between warm and cold weather.

It looks like the warm to hot and dry weather will stick around until at least Saturday, before cooler weather moves in. A large ridge of high pressure will dominate our region all week before a large area of low pressure finally pushes it out over the weekend. This area of low pressure is forecast to push across the far northern parts of the Prairies over the weekend. While this will not bring any precipitation to southern or central regions, it will usher in some cooler air once the low pushes by on Sunday. Temperatures on Sunday and Monday will be on the cool side, with highs struggling to reach 20 C.

Next week the weather models show another ridge of high pressure developing to our west and then building eastward. This should bring mainly sunny skies along with warming temperatures. Daytime highs by Wednesday or Thursday should be back into the mid-20s, which is at the high end of the usual temperature range for this time of year.

Usual temperature range for this period: Highs:14 to 24 C. Lows:2 to 12 C.
