Rain, thunderstorms to sweep through Calgary on Thursday

We had a nice reprieve from the instability on Wednesday, with an ample amount of sunshine and temperatures within the seasonal range.

But that all changes once again later tonight.

An upper low pressure system circulating over central B.C. is heading our way and could bring rain and a thunderstorm risk as early as 11 p.m. tonight.

Following that event, more rain will push into Calgary early Thursday morning and won’t start to dissipate until around 4 p.m.

Rainfall totals are modelling to be anywhere from 10 to 20 mm for Calgary, but so far, no rainfall warnings or thunderstorm watches/warnings have been issued by Environment and Climate Change Canada (ECCC).

This will once again cool our temperatures across the province, with a below seasonal high of 15C expected for the city on Thursday.

Expect another bounce back on Friday though, with clearing conditions bringing sunshine and a comfortable high 22C --but again, it will be short lived.

An upper low pressure system will develop once again in B.C. and move into central Alberta on Saturday and Sunday bringing more rain and thunderstorm potential.

Expect temperatures to only reach the high teens from Saturday through to Monday.
