Humid with Thunderstorms

A very warm and humid air mass remains in place over Montreal this morning. Overnight the temperature remained very warm, only dropping from yesterday's high of 29C down to around 25C at 1am when nocturnal thunderstorms rattled the city. The sultry air remained after the storms and the temperature only lowered to 21C. We are at 23C and should warm to 28C with a humidex of 36C today. This will be combined with afternoon showers and thunderstorms as a cold front arrives from Ontario. Some of the storms could produce very heavy rain again so be aware of that on area roads. The other night the Metropolitan (Highway 40) service road at L'Acadie flooded once again trapping several cars, so my advice it to steer clear of the area today if more storms occur.
