gonna be tight this evening...

Looks like the evening peak started mid-morning instead ...

Yes, yesterday and today have had fairly flat and high day time
demand profiles. Unlike the working days last week (or even the
weekend) with lower demand morning/afternoon and defined early
evening peak.

Why?

It's been colder.
