THUNDER BAY — A shift in weather patterns may threaten some high-temperature records in Northwestern Ontario in the days ahead.
Environment Canada says the thermometer will climb into the high twenties and low thirties in the Thunder Bay region through the first 10 days or so of June.
It's forecasting plenty of sunshine and temperatures in the city ranging from 24 C to 31 C between Wednesday and next Monday, and likely for at least a couple days beyond that.
The normal daily maximum in Thunder Bay at this time of year is only 19 C.
Meteorologist Jeff Coulson said the new weather pattern will draw warm air into Northwestern Ontario from the U.S. deep south.
"Temperatures will continue to be well above normal through the weekend and into the middle part of next week. In fact, we may even see some records threatened, especially for Friday, and then later on, especially the 7th, 8th and 9th. Those records look vulnerable if we get into the low 30s," Coulson said.
He cautioned, however, that people living along the lakeshore will have a different experience.
"It's going to be a lot cooler. Lake Superior is still that big refrigerator."
Environment Canada reported Monday that last month was slightly colder than normal in Thunder Bay, with an a daily average temperature of 9.2 degrees.
