OTTAWA -- It’s not the heat—it’s the humidity.

For the next couple of days, that old maxim could be the case in the capital. The high on Tuesday will be a seasonal 22 C, but the humidex will make it feel more like 27.

There’s also a 30 per cent chance of showers late in the afternoon, along with the risk of a thunderstorm. The UV index will be high.

On Wednesday, the high will be 21 C with a humidex of 25. There’s a 30 per cent chance of showers early in the afternoon.

Thursday and Friday will see a mix of sun and cloud with highs in the mid-20s. Expect that trend to continue into the weekend.
