Friday will be mainly sunny and hot. The days that follow? No so much...

Friday should be warmer than Thursday, and Thursday was already pretty warm! It's expected to cool off again over the weekend, though, especially Sunday.

One more day of sun and heat before things cool and the rain returns on the weekend.

Friday will be mainly sunny, with a high of 28 C.

The clouds will creep in later in the day, and it will be breezy at times.

Late Friday in Calgary, there is a small chance of showers or thunderstorms.

On the weekend in the city, expect on-and-off rain, heavy at times.

We will likely pick up 15 millimetres of rain (Friday night through Sunday).

Temperatures will cool, too.

By Sunday, we’ll be in just the low 20s.

You’ll see some weird clouds off to the west over the next 24 hours. Here is a picture from Dawn Erickson taken in northwest Calgary on Wednesday:
