With winter just three weeks away, many are already asking what's in store for us here on the prairies.

Terri Lang, with environment Canada, explains that they are expecting La Nina to be a factor this season.

"Usually with the La Niña winter, we get colder than average temperatures," she said.  "We also get above average snowfall or precipitation through the winter so that's why the forecast is saying that, those are the indicators, but like we saw last month pretty much anything can happen."

Lang added that predicting the weather can be a tricky thing to do and we see that from time to time, especially here in Saskatchewan.

She explains how they try and determine what the long-range weather will be like.

"We do use indicators to try and tell us what the winter will be like," she said. "We usually use El Niño, La Niña, or La Nada are three indicators. We have a weak La Niña happening this year, and that's the colder than average sea surface temperature off the coast of South America.

Lang says that they are predicting a cold, and snowy winter for the area that should arrive on Sunday.
