Markham, ON - The Colorado Low finally departed from us, and we have seen approximately 30 mm across the Greater Toronto Area, while significantly more (up to 50 mm) of rain across Cottage County, the "Nickel Belt", and Simcoe County. Barrie, Ontario had reported around 43 mm, for instance. They were primarily affected by the stationary warm front that "lags" the area, dumping continuous rain, while the GTA bathed in sunshine in the warm sector of the low pressure.

Cooler air funneled through behind the bulk of the system. With that, strong northwesterly winds affected much of Southern Ontario and Southeastern Quebec last night. Wind warnings were issued in some parts of these regions, as wind gusts were as high as 100 km/h in some open areas. In Toronto Downtown, the wind gust was reported at 89 km/h.

The cooler air affected the region today, as the high pressure comes along. Northerly flow of air gives Southern Ontario a cool, yet pleasant day. Most of Southern Ontario had reached their daytime high today, at 6 C for the GTA.

Tomorrow, as the high pressure tracks east, we will enter the sector where we see southerly flow from the high pressure (high pressure circulates clockwise), and hence, with that, a "bump" in temperature. Expect partly cloudy skies tomorrow and a high of 10 C for GTA, up to 17 C possible for Windsor and the Niagara Peninsula.

One last note... Windsor, Ontario and St. Catharines, Ontario made the national warmest spot for the past 3 days! Congratulations! We had not have this type of news since January!
