May 13, 2011 — Temperatures have been steadily climbing in southern Ontario this week. The heat and humidity triggered thunderstorms across the region Friday.

With a combination of sunshine, mild temperatures, humidity and even thunderstorms, it's been looking and feeling a little more like summer in southern Ontario this week.

On Friday, southwest winds and a ridge in the jet stream let to above-normal temperatures and even some summerlike humidex readings across the region.

Toronto's seasonal average for this time of year is 18C, but the city hit a high of 26C on Friday, with the humidex making it feel like 32C. In Hamilton, it felt like 34C.

The warm temperatures, humidity and an incoming cold front created ripe conditions for thunderstorms, which began to pop up in the late afternoon along the Huron shores.

The storms were non-severe, producing only brief heavy downpours and pea-sized hail in places like Stratford, Guelph and Kitchener before fizzling out over the north shore of Lake Ontario.

On Thursday morning, thunderstorms rolled across parts of southwestern Ontario, including Windsor and Leamington. By the afternoon hours, storms producing pea-sized hail and heavy downpours were reported in Sarnia and Chatham.

The heavy rain has also flooded farm fields in several areas. The onset of wet weather has significantly delayed the crop season for Ontario farmers.

And it's a gloomy outlook for producers. Rain showers are expected to persist through Wednesday, washing out any improvements farmers have made so far.
