Melbourne will feel the heat for the start of the week but it’s not sticking around for long.

In fact, it will nosedive before we even get to dinner.

A top of 38 degrees is predicted for today but a cool change before 8PM, will mean tomorrow will not exceed 19 degrees.

During the cool change between 6PM and 8PM, temperatures are expected to drop by 15 degrees.

Top temperatures for the rest of the week are forecast to be between 19 and 22 degrees.
