Hot weather returns to Montreal this weekend

The heat and humidity will build as we head into this weekend with highs reaching 30C in Montreal. (AccuWeather)
It has been a rather soggy start to August across southern Quebec. I recorded nearly 36.6mm of rain at my home on Tuesday alone, with 47mm at Trudeau airport. The heavy rainfall of the last 48 hours has brought the monthly total at Trudeau Airport to 87mm. This is well above normal for August and nearly a full months rain in just the first 12 days. The long term average for Montreal is 94mm for the entire month of August. The forecast for the next couple of days will see a chance for more showers and thunderstorms, especially Friday afternoon. Afterwards we will begin to see an increase in temperatures as we head into the upcoming weekend. Sunshine both Saturday and Sunday will push the mercury up to 30C (86F) across southern Quebec. By Monday we may even see a few low 30's for highs, close to 90F from southern Ontario into Quebec and New Engalnd.

The heat is already building across western Canada. On Wednesday, Lytton, BC had a record high of 40.2C (104F) surpassing the old high of 39.7C. Estevan, Saskatchewan was 36.7C (98F), and Regina 32.9C (91F). The heat will remain into Saturday for the west with highs reaching well into the upper 30's with perhaps an isolated 40C. A strong cold front will bring an end to the heatwave out west by Sunday as it races across the Prairies and into Ontario and Quebec by next Tuesday. Strong to severe thunderstorms are likely with this front as it marches east across southern Canada.
