More thunderstorms for Montreal

It was a perfect day on Saturday for the annual Cruisin At The Boardwalk in Sainte-Anne-de-Belleveu on the shores of Lac St. Louis. (ValleyWX)
The good news is there is sunshine on the way for the balance of the work week here in southern Quebec. The bad news is we can expect more showers and thunderstorms today before we see any clearing. After a spectacular, near perfect Saturday with warm temperatures and sparkling blue sky, Sunday was less than perfect. Early highs of nearly 20C were quickly cooled with northeast winds and rain ahead of a slow moving warm front. About 10mm of rain fell here on L'Ile Perrot to increase the monthly total to over 120mm. A trailing cold front will move across the St. Lawrence Valley this afternoon with some fairly strong showers and thunderstorms along it. Small hail, gusty winds and a decent amount of rain as much as 25mm are possible with any storms from Ottawa to Cornwall to Montreal and points south. The threat will diminish by late in the day as the front settles south into New England. High pressure will then enter Quebec with sunny skies for the balance of the week and near seasonable temperatures warming from 22C to near 27C (80F) by Friday.
