Environment Canada said the incoming cold front is expected to produce brief periods of intense snowfall and reduced visibilities throughout the city.

A drastic change in conditions is expected for southern and central Alberta on Friday, when a Pacific low will bring snow, wind and a big swing in temperatures.

The City of Calgary will outline its snow and ice-clearing strategy on Tuesday.

The first week of fall is now in the books and it's been full of sunshine in Calgary — a stark contrast to the weather in the province this time last year.

All of southern Alberta has been put under a special weather alert by Environment Canada, as a low-pressure system brings showers and possibly even snow. 

New daily maximum temperature records were set in 11 Alberta communities on Monday.

Environment Canada issued heat warnings for most of Alberta, saying over the long weekend temperatures will reach the high 20s to low 30s and not drop much overnight.

Calgary police are warning people to protect themselves against break and enters, saying warm weather normally leads to an increase in cases.

There is expected to be a slight break in the heat on Thursday, before the hot temperatures return for the long weekend, according to Environment Canada. 

Several Alberta communities have been placed under a heat warning Monday as temperatures are expected to soar to 29 C or higher for the next two days.
