Things are going to get hot in the capital for the next few days.
The warming begins Wednesday, with a high of 32 C predicted, with humidity making that feel like 34 C and a UV Index of 8, or very high.
Environment and Climate Change Canada lists the highest May 31 temperature in history as 32.6 C in 1944, so the record is definitely within reach.
The average high for this date is 21.9 C.
Things are looking even more scorchy for Thursday, with a high of 33 C predicted. Humidity is expected to be about 35 per cent, while the UV Index looks like about 8, or very high.
The weather office says some relief should arrive Friday, as a weather system should be bringing a 40-per-cent chance of cooling showers through the day.
Still, the high is forecast at 31 C.
By Saturday and Sunday, the meteorologists are looking for highs of about 26 C, with clear skies Saturday and mixed sun and cloud Sunday.
While there has been no official heat warning yet health officials recommend hot weather protection measures, such as avoiding over-exertion, stay hydrated, seek shade, wear hats and cover open skin wear possible.
For about a week, weather patterns in most of Ontario have been government by a phenomenon known as a “Rex block.” Briefly, a Rex block is a strong high pressure system that pushes low pressure systems aside.
The description became popular on social media with a variety of humorous “illustrations” showing a high pressure system in the shape of a Tyrannosaurus rex.
In a tweet last week, ECCC drily noted such illustrations may contain scientific inaccuracies,
An extended period of warm and dry conditions is expected for most of the province due to a developing Rex block! Looking at the model loop below, only far northwestern Ontario expects rain in the coming days. Image may contain scientific inaccuracies 🦖 pic.twitter.com/ZFcOidneKD
