It was not a bad weekend across southern Quebec, temperatures were rather warm with plenty of sunshine especially early in the day. There were also some decent thunderstorms around producing lots of hail in the Ottawa Valley on Saturday. We can expect another warm day today with an increased risk of showers and thunderstorms this afternoon. The trigger will be a backdoor cold front, one that moves from northeast to southwest across the St. Lawrence Valley. Temperatures today will reach 26C (79F), but will dramatically cool behind the front down to 14C (56F) tonight and not much better than 16C (61F) on Tuesday with showers forecast for Montreal. Wednesday looks like the best day of the week with sunshine and 21C (70F).

After a mainly sunny day Sunday in Montreal, a narrow but strong line of thunderstorms developed and rapidly moved across the St. Lawrence Valley around 6:15pm. There was lots of lightning on L'Ile Perrot along with gusty winds. Little rain fell with only 1.6mm at my home and 4.6mm at Trudeau Airport. The airport did report a wind gust to 65km/h with the storm. Some small hail was also observed across the West Island and off island to the northwest..
