Yes, it's chilly and no it's not going to get that much warmer

If you’ve started to miss summer weather – bright sunshine, warm breezes, high temperatures – then you’re going to have to keep on missing it today.
At 7:00 a.m., Environment Canada measured the temperature in Ottawa (weather is officially observed at the airport) at a downright chilly 3 C.
Today’s high is going to be a not very summery 9 C. There’s also a chance of showers (mostly in the morning) and the rest of the day should be a mix of sun and clouds.
