Cooler and wet weather on the way for Montreal

This is what is left of winter 2014/2015 in many parts of the city of Montreal. It amazes me every spring just how much people litter in the winter. Do they not think it will surface in the spring? I keep a a bag in my car, it takes a few seconds for each of us to put garbage where is belongs and avoid this mess each year. The highways are lined with it, especially near shopping malls.(ValleyWX)

The weather will be spectacular today with sunshine and warm high temperatures up to 17C (63F) in Montreal. L'Ile Perrot is currently -2C (28F) as we continue with the wild diurnal temperature swings. This is common in spring, but the difference from high to low this past Monday was truly amazing. The overnight low at my home was -0.4C (31F) reached around 6am. By 3pm in the afternoon the temperature had warmed all the way up to 25.6C (79F) here on L'Ile Perrot. You can do the math on that one, a remarkable warm-up in such a short period of time.

Not much snow left on the ground on a 26C April day in Montreal.

High pressure that has been in control of the weather for most of this week will slide off the east coast today with a warming southerly flow. A frontal boundary will arrive overnight with showers into Friday before some clearing late in the day. On Saturday more showers are possible as another weak disturbance moves across southern Quebec. The mild temperatures of this week will begin to cool by the weekend with an extended period of below normal weather expected next week. High temperatures will range from 10 to 12C (50 to 55F) with lows of 4 to 6C (40 to 43F) into next week. In addition to the cooler weather, there will be frequent periods of rain next week with perhaps some significant amounts.
