While the first day of fall is still a few weeks away, it seems as though winter is on its way in Alberta after areas in the mountains saw snow this week.

Environment Canada also issued frost advisories for a large area of southern Alberta on Wednesday.

"Clearing skies combined with a cool air mass will allow temperatures to fall close to the freezing mark in portions of central Alberta. Patchy frost is expected," said the national weather agency on its website.

"Take preventative measures to protect frost-sensitive plants and trees."

While Calgary is not included, there are many areas under the advisory:

- Airdrie, Cochrane, Olds and Sundre.

- Drayton Valley, Devon, Rimbey and Pigeon Lake.

- Drumheller and Three Hills.

- Hanna, Coronation and Oyen.

- Leduc, Camrose, Wetaskiwin and Tofield.

- Okotoks, High River and Claresholm.

- Red Deer, Ponoka, Innisfail and Stettler.

- Rocky Mountain House and Caroline.

Rainfall warnings ended for the southwest corner of Alberta on Wednesday night.

But the rain also brought snow for higher elevations, which is typical for this time of year in the Rocky Mountains.

Web cams on some Alberta highways, such as Highway 22, showed the white stuff falling throughout the morning.

"A low pressure system moving through Montana continues to produce heavy rain in southern Alberta," said Environment Canada on its website. 

"Further amounts of five to 10 millimetres are expected in the warning regions. Heavy rainfall will end this evening as the low continues eastward."

CBC weather specialist Craig Larkins said nicer weather is on the way. He said it's supposed to warm up for the weekend.
