Arctic cooldown hits Ontario hard..10 Deg C
Temperatures plummet this week in Ontario, putting us colder than the daytime highs we saw in late December. As well, with the cold comes widespread rain and very gusty conditions
A low-pressure is expected to track into the lower Great Lakes region and stall, cycling showers as far as northern Ontario and southern Quebec. With this slow-moving system, Ontario can expect days of cloudy skies and rainfall–– in addition to the chilly temperatures.High pressure situated in Northern Canada and a stubborn upper trough in the U.S. will join forces to create a significant, late-May temperature rut that will take days to climb out of.Did you Know? Highs in the 8°C to 9°C range are typical of late-March weather in the Greater Toronto Area (GTA).By Saturday, close to 40 mm of rainfall is forecast to fall all across the GTA and a wide swath of southern Ontario. It’s a lot of rain, and about the same amount the region received in all of May 2020 (40 mm) and May 2022 (47 mm).
The jet stream, which normally keeps systems moving from west to east, will dive well south--leaving an upper trough detached from the main upper-level winds.By Wednesday evening, sustained winds along the west end of Lake Ontario are between 30-40 km/h, with gusts of 60-70 km/h possible through early Thursday.And, for those residing in the GTA, the pesky, easterly wind will further keep temperatures on the cool side in Toronto and other communities adjacent to Lake Ontario. Water temperatures right now are only at 10°C or 11°C.
Wednesday: 11°C | Thursday: 10°C | Friday: 10°C
