I hope you've been enjoying the mild weather in recent weeks because the all too familiar pattern that we dealt with for much of the winter is setting up again.
A deep low pressure system will develop over Ontario and Quebec this week and then remain in place for at least the next 7 to 10 days as a blocking pattern sets up across the country. This will ensure us an extended period of chilly, unsettled weather.
Temperatures will turn progressively cooler each day and by Thursday and Friday, highs will struggle to climb out of the lower 40s. Overnight lows will dip below freezing in many areas.
A series of disturbances rotating around the main upper level low will bring scattered showers and gusty winds each day through Friday. Some flakes will mix with the rain at times but little accumulation is expected.
As mentioned, it doesn't look like this pattern will break until the first week in May so keep the sweaters out and pack away the shorts and t-shirts for awhile.
