Heavy rain & thunderstorms

A large area of heavy rain and thunderstorms is moving north into eastern Ontario and Quebec. A heavy rain warning is in effect in southern Quebec and may be extended west into Ontario. About 30-60mm can be expected. The culprit is low pressure that will lift north into the central lakes as the day moves on. Some snow will occur around northeast Ontario (Sudbury, North Bay) on the western flank of the system but should not occur in our area.

While rivers and streams will rise they should remain below flood levels as a result of this rain. Some frost may occur Tuesday and Wednesday night on the backside of the storm as cold air moves in and clearing skies.
