Heat warnings remain in the south with thunderstorms possible in central Alberta

Risk of thunderstorms in central Alberta. Jodi Hughes has a look at the five-day forecast from the Sky Watch Weather Centre.

Calgary was one of five Alberta communities to set a new maximum temperature record on Tuesday with a high of 31.8 C.

The old record of 31.7 was first set in Calgary in 1886, and that temperature was repeated in 1908 and 1919.

According to Environment and Climate Change Canada (ECCC) the other maximum temperature records were set in the Bow Island area (32.6 C), Drumheller area (33.6 C), Esther area (32.5 C) and Sundre area (31.8 C).

Wednesday’s highs will be cooler for most of the province outside of the southeast corner, but they will still sit above seasonal in most locations.

Heat warnings remain for the southern portion of Alberta and Saskatchewan due to elevated temperatures but these warnings should be lifted by Thursday.

A frontal system will move through Alberta on Wednesday and heighten atmospheric instability.

This will contribute to thunderstorm development in the central zone and assist in cooling things down by Thursday.

Some of those thunderstorms could become severe in nature, with the greatest threats including large-sized hail and damaging winds.

Heavy rain in possible in the east-central portions of British Columbia, prompting ECCC to issue a special weather statement for that area.

Rain is possible in Calgary on Wednesday and expected on Thursday, before a nice start to the weekend.

Daytime highs from Friday to Sunday will range from 25 C to 28 C, with a chance of rain on Sunday.
