We get tempertaure dumps like that in summer. I don't like it! Our temp here today is 16C.
We will get drops in temp but never like this.
It was 9C this morning - brrrr!
This afternoon it warmed up to 25C with no humidity to speak of.
Currently it’s 23C forecast low of 13C.
The heat is back on again tomorrow, and risk of severe weather.
