Hi, everyone and welcome to Melbourne Express on this already-sweltering Friday. I'm sure I'm not alone in being extra-tired this morning after a very stuffy, sleepless night. I'll have more on today's extreme heat and weather risks in a moment.

So far things are looking good on the roads and trains. Let me know if you see anything noteworthy on your commute in the comments, via Twitter or by emailing [email protected].
