It’s going to hit a low of 4°C this week in Mississauga and Brampton

A cold front coming through Mississauga and Brampton makes for a seasonally appropriate and cooler week ahead.

Some rain came down in the region today (Sept. 18) with a 70 per cent chance of showers expected to continue overnight. The wind is coming from the west at 20 km/h, gusting to 40 km/h at times.

Thunderstorms are possible in the afternoon tomorrow (Sept. 19) ahead of a cold front making its way through the region.

Some storms could become severe tomorrow with the threat of up to 3 cm of hail and winds gusting to 70-90 km/h.  Large hail can damage property and loose objects may be tossed by the wind and cause injury or damage.

Uncertainty is high, as the timing of the cold front moving through southern Ontario will affect the likelihood of severe weather.

Tuesday (Sept. 20) is expected to be sunny with a high of 24 degrees Celsius and a low of 15.

The rain then returns on Wednesday (Sept. 21) with a 60 per cent chance of showers lessening to a 30 per cent chance into the evening.

The high will sit around 23 degrees Celsius but with the combination of humidity values and showers it will feel more like 32 degrees.

Thursday (Sept. 22) marks the autumnal equinox and official first day of the fall season. The day will be characteristically cooler with a 30 per cent chance of showers and a high of 15 degrees Celsius.

Overnight on Thursday the low is expected to reach plus 4 as the chance of showers continues.

Friday (Sept. 23) remains cooler with a high of 16 degrees Celsius and low of plus 4 overnight.

Even with the cooler seasonal temperatures expected this week, the heat is not quite gone yet.

Weather historian, Rolf Campbell said that a high of 28.5 degrees Celsius recorded this afternoon marked the hottest Sept. 18 Peel Region has experienced in 67 years.

The last time it was this hot on Sept. 18 was the year 1955 when the temperature hit a high of 32.2 degrees Celsius.
