Much calmer weather week ahead for southern Quebec

The weekend was spectacular across southern Québec, with sunny, warm weather. Conditions were less humid and thankfully no thunderstorms. (Valley Weather)

We are looking at the calm after the thunderstorms for most of southern Quebec. Last week was filled with multiple rounds of thunderstorms, wind damage, power outages, flooding and searing heat. By stark contrast, the weekend was calm and spectacular, finally dry for many, warm but less humid. 

High pressure has settled into eastern Ontario and southern Quebec to start the work week. This will keep low pressure well to our south across the Ohio Valley, eastward into the middle Atlantic states. This region will be the focus of heavy rainfall Monday along with thunderstorms. Flash flooding has occurred or is expected from Ohio east towards New York City. Flood watches are in effect from Virginia to southern New England.

Meanwhile here in Montreal and across southern Quebec and eastern Ontario, we can expect nothing but sunshine, with highs between 28C and 30C (83-86F). Overnight lows will remain pleasant, dropping into the middle teens. 

The next chance of shower activity will not be until Thursday, with the arrival of a cold front. Showers and scattered thunderstorms are possible. Skies clear out for Friday, with another fair weekend expected at this time.

Rainfall has been highly variable across our region this July. Parts of Ontario and Quebec have measured well over 100mm of rain to date, while Trudeau Airport sits at 24.5mm. I have recorded a paltry 2.6mm at my weather station on Ile Perrot. Municipalities on the West Island are still cleaning up from the major flood on June 22, while nearly 1900 homes were flooded in the Ottawa area on July 1st.
