The hot, hot heat that's been blanketing Waterloo region, Guelph and Wellington County this week came to an end Thursday morning.

Environment and Climate Change Canada issued a heat warning for the area earlier this week, warning temperatures would reach daytime highs of up to 34 C, feeling like up tp 42 C with humidity, and there would be little relief overnight.

"Showers and thunderstorms moving through Thursday morning are expected to keep daytime temperatures relatively cooler for most regions, bringing an end to the heat event," the weather agency said in its heat warning.

"For regions not affected by showers, a cooler airmass will bring an end to the event by Thursday night."

Rain on Thursday morning over Waterloo region brought a reprieve from the heat.

The weekend forecast shows more average temperatures for this time of year in the mid-20s:

  • Friday, sunny and 24 C.
  • Saturday, mix of sun and cloud with a chance of showers at 25 C.
  • Sunday, mix of sun and cloud with a chance of showers at 26 C.

By Monday, the temperature is expected to start creeping back up to the high 20s with a mix of sun and cloud.

When the heat returns, people are reminded to take precautions such as drinking water, seeking cool and shaded spots and watch for signs of heat exhaustion.
