Occasional storms but not a washout for the weekend in southern Ontario; cool pattern next week

Thursday, July 24, 2014, 4:27 PM -

Once again, Friday will feature some of southern Ontario's nicest weather of the week as sunshine returns and temperatures warm to near seasonal for the afternoon. However, the dry weather will not last into the weekend. 

EXTENDED ACTIVE WEATHER COVERAGE: Tune in to The Weather Network for live updates on the summer storms in your area. Our team of reporters and meteorologists in the field provide you with the most accurate and up-to-date coverage.

Saturday will be mostly cloudy with the threat for occasional showers and thunderstorms, especially during the morning and then again late in the day, but we will have rain-free periods as well during the day.

Sunday will also bring the threat for scattered showers and thunderstorms, but at this point Sunday looks like the better of the two days this weekend with the potential for several hours of sunshine and temperatures rising to the mid to upper twenties.

However, late on Sunday widespread rain and thunderstorms will approach the GTA, bringing a period of wet weather for Sunday night and into Monday.

For next week, a slow moving upper level low will bring occasional showers and cooler temperatures. Each day next week will bring periods of dry weather with a mixture of sun and clouds, but we will also have the threat for showers, especially on Monday.

Temperatures early next week will feel more like early fall with highs only near 20 in the GTA for Monday and Tuesday and in the mid to upper teens across cottage country.

Our temperatures will slowly recover for the end of next week, but there is no sign of any hot weather in the long range forecast. For the civic long weekend, temperatures should be near to just below seasonal. Our average high temperatures during early August are near 27ºC in the GTA and 24ºC in Muskoka, so temperatures that are just below seasonal can still be enjoyable for most outdoor activities.

It is too early to determine the threat for rain on specific days during the long weekend, but at this point we do not see signs of a major system. However, with the expected pattern we will likely see the threat for at least scattered showers at times. We will continue to post updates as we get closer to the long weekend.
