"We have a trough of low pressure that's moving through the province and unfortunately that, in combination with some upslope flow, is causing some snow over Southern Alberta," explained meteorologist Heather Pimiskern. "Not insignificant amounts of snow either; we've seen and heard reports of between 10 cm. and upwards of 40 cm. as of 8:00 a.m."
"We have a band of precipitation that's moving through the Drumheller region and there's quite a bit of heavy snow imbedded within it," she extrapolated. "Because of the way these bands are setting up, it does mean that there will be some localised heavier snowfall amounts in some regions."
The snow is expected to last throughout the day and into the night, but Pimiskern says a ridge of high pressure should move into the area tomorrow, bringing sunshine with it.
