Rainy Friday - perfect weekend for Montreal

More rain is forecast for southern Quebec today, prompting Environment Canada to issue a Special Weather Statement for the Townships. Over 30mm (1 inch) of rain is possible in the same area where cleanup continues from Tuesday nights flooding. (Photo Alex Leduc CBC News)
Another wave of low pressure and frontal boundary will pass south of Montreal over the next few hours with more rain and thunderstorms forecast. Expect 15-30mm of rain for Montreal through midnight with more than 30mm in some of the flood weary sections of the Eastern Townships.  It will be a mild and muggy day with highs near 23C (73F). It has been a wet month so far in southern Quebec with 54mm measured at Trudeau Airport through June 10 and 57.4mm here on L'Ile Perrot. Much more precipitation has fallen in other parts of southern Quebec, well over 100mm in portions of the Townships. Thunderstorms are possible as well but the strongest storms will remain south of Montreal in New York. Storms late Wednesday evening were rather spectacular all around L'Ile Perrot once again and especially across the southern Laurentians and Laval. So far every wave of severe weather this season seems to be skirting around the perimeter of Montreal.

The good news for eastern Ontario, southern Quebec and northern New England is that high pressure will build into the region for a sunny and dry weekend with high temperature near 26C (79F) both Saturday and Sunday. Overnight lows will be very pleasant near 16C (60F). More rain returns for Monday.
