Unsettled, chilly weather week ahead for Montreal

The weather will not feel like May this week as a series of frontal boundaries and an upper level low combine to bring us a chilly damp week. Monday will be mostly cloudy, but with some breaks of sun, allowing temperatures to reach into the upper teens, perhaps 20C (68F). It will likely be the best weather day of the work week. 

Clouds thicken this afternoon and showers arrive Monday night into Tuesday, along with a few rumbles of thunder. Temperatures will remain mild through Tuesday evening, dropping to 11C (52F) and perhaps reaching 21C (70F) Tuesday. By Wednesday, and upper level low over the Great Lakes will move towards Quebec City, keeping a damp, chilly airmass in place over the St. Lawrence Valley. Temperatures will drop into the lower teens for daytime highs, along with cloud cover and occasional showers. Overnight lows will be in the single digits.

The aforementioned low will slowly drift into Atlantic Canada by the weekend, but may be replaced by another area of low pressure. While the week will not be a complete washout, the weather will certainly not feel very springlike. However as we have seen in the last week or so, it does not take much sunshine to push temperatures up quickly. We can only hope those breaks of sun will be more numerous than the forecast predicts.
