Weyburn and area saw the biggest dump of snow it has seen so far this winter on Sunday. An average of 11 centimetres of snow fell yesterday and throughout the night, according to Environment Canada, which relies heavily on volunteers to measure snowfall in the Weyburn area.

Warning Preparedness Meteorologist Terri Lang explained that Environment Canada doesn't have anyone measuring snow on the ground in Weyburn.

"We do have a volunteer weather observer but he's only measuring the water equivalent so that doesn't really help us but we can kind of go by what the automatic weather station has and it kind of looks like seven centimetres worth off snow fell as far as I can tell," said Lang.

The automatic weather station Lang refers to is at the Weyburn Airport and is not a reliable source for figuring out snowfall amounts, according to Lang, due partly to high winds in the area and the fact that it is unmanned.

Thanks to measurements taken by the Discover Weyburn news team, Lang was able to calculate the average based on snow on the ground. She changed the average to 11 centimetres, averaging three measurements taken in areas protected from the wind and away from drifts.

Three separate snowfall measurements taken in downtown Weyburn show 9 cm, 10 cm, and 14 cm of snow early Monday morning.

Lang said they appreciate anyone taking snowfall measurements and passing the info onto Environment Canada via social media by tagging #skstorm.

More snow is on the way, according to Lang, with a few more centimetes falling tonight and another two to five centimetres falling tomorrow. After the weak weather system that is bringing the snow Tuesday passes, the southeast is in for an extreme cold snap.

"Right now it's cold, windchills getting down into the minus thirties, but it looks like we're going to get even colder. Temperatures, actual air temperatures, closer to -30 with windchills closer to -35 or lower so we may get into those extreme cold warnings by mid-week so people should be prepared for that," said Lang.
