Atypical warmth hangs on in Ontario, but pattern change and rain looms

We're nearing the midway mark for October and temperatures still don't reflect the time of the year, with a prolonged period of warmth remaining across the south for this week. The very warm pattern continues ith temperatures more typical of September, and near record warm overnight low temperatures, too. There will be some chances of some unsettled weather to come, though, during the final days of the mild temperatures. A trough will look to bring temperatures back down to near seasonal in the region for the weekend, and a developing potent stateside system is expected to bring considerable rainfall, as well. More on the warm stretch, how much longer it will last, and the incoming bout of heavier rain on the weekend.

THIS WEEK: STRETCH OF BALMY TEMPERATURES HANGS ON BEFORE PATTERN CHANGE

The string of mild October days is set to persist for at least another few days. Daytime highs will remain into the low 20s right into Friday for many places.

The pleasant temperatures won't be without a bit of unsettled weather, however. Wednesday and Thursday will see the chance of spotty showers, thanks to multiple weak systems trekking through, though no days will be a washout as there will be some glimpses of sunshine mixed in.

Enjoy the September-like warmth while you can as a trough will bring a pattern change heading into the weekend, but the good news is that the tumble won't be too drastic. In fact, temperatures will still be a couple of degrees above seasonal.

A rapidly strengthening system will track into the Great Lakes region Friday night and Saturday, bringing a widespread soaking rain to southern Ontario. Moisture from what will be the remnants of Tropical Storm Pamela will help boost rainfall amounts.

Much cooler temperatures will funnel in behind this system with some lake effect showers expected into Sunday. There will be a brief warm-up early next week, then another shot of cooler weather later in the week.

More changeable daytime highs are expected for the second half of October, but temperatures will still tip to the warm side of seasonal.
