Here's the release from Environment Canada:

Snow squall watch in effect for:
- Foothills Co. near Cayley
- Foothills Co. near High River and Aldersyde
- Foothills Co. near Longview and Eden Valley Res.
- Foothills Co. near Okotoks and De Winton

Brief, heavy snowfall is expected. Poor visibilities in heavy snow and blowing snow are possible today.
An intense cold front is bringing a band of heavy snow and strong winds to southern Alberta.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather. Visibility may be significantly and suddenly reduced to near zero.
Snow squall watches are issued when conditions are favourable for brief but intense bursts of heavy snow producing near zero visibilities.
