Discussion
The overall weather pattern will remain quite unsettled around here over the next few days with the threat for more torrential downpours and localized flash flooding. The combination of an extremely humid air mass, a stalled out frontal boundary zone, and multiple low pressure systems should be able to provide enough “lift” in the atmosphere to result in additional heavy rainfall and given the already well-saturated grounds, this can lead to flash flooding conditions. As far as temperatures are concerned, it will not be as warm today as recent days and below-normal temperatures should be the rule for Friday and the upcoming weekend as strong high pressure builds across southeastern Canada.
