After at times, an up and down start to the summer season, the heat is going to linger for quite some time.

Sunshine and hot temperatures are in the forecast for a period that is expected to last anywhere from one to two weeks, according to Environment Canada.

Meteorologist John Paul Cragg says that it will be mostly dry as well.

"We're not looking at any general rainfall coming to the area. But with pop-up thunderstorms, some areas could see a lot of rain, while others could be very dry over the next couple of weeks."

"It's going to be luck of the draw," he noted.

Cragg says that the thunderstorms are created directly because of the heat.

"It's the time of year when you start seeing temperatures get that high. With that air, the ground wants to rise up. It's like a hot air balloon," he explained. "You've got the sun pounding down on the ground, it's warming air on the ground and then that air starts to rise and you get these thunderstorms."

With temperatures on the edge, or into the low 30's, the humidex could push conditions closer to the mid 30's to 40-degree mark.

Cragg says that is when they issue "too hot" notices.

"We've changed our heat warning criteria," he said. "We issue a heat warning when the humidex is over 38 degrees, or if we are forecasting that. We've also changed the heat warning for extended periods of heat."

Daily highs will average around 30, with lows hanging around the 15-degree mark.
