It is currently looking like we will miss out on any significant storm systems for this forecast period. The main weather maker across central North America will be an area of low pressure moving out of the American Midwest. This low will be staying well to our south as it slowly meanders towards southern Ontario.

Over our region weak high pressure will be in place for the middle of the week. This high should bring some sunshine with it, but clouds look to move back in during the latter half of the week as a weak area of low pressure pushes in from the West.

This area of low pressure may bring some showers with it over the weekend but it does not look like there will be any significant precipitation with this system. For the first half of next week it looks like we will be between systems with no strong systems nearby. Temperatures should continue to be fairly nice with highs on most days in the 6 to 10C range.

Looking beyond this period, the models are hinting at an outbreak of cold air late next week – hey it is getting close to winter!

Usual temperature range for this period: Highs: 2 to 15C Lows: -7 to 2C

Probability of precipitation falling as snow: 40 per cent
