Spring is nearly over with the official start to summer this Sunday, June 21. It has not been a very good month so far after what was a brutal winter. Montreal has had over 90mm of rain so far and the month is not over. Southern Quebec remains north of a sultry air mass affecting the central and deep southern US. More showers and thunderstorms are expected today as a cold front crosses southern Quebec. As with Tuesday, some of the showers may be rather heavy. Over 25mm of rain fell on Tuesday across the island of Montreal. The rain caused some minor flooding in several neighborhoods. Before the showers and storms arrive today we are looking at sunshine mixed with clouds and a high of 27C (81F). Behind the front tonight cooler air arrives with a low of 10C (50F). On Friday and Saturday look for sunshine with low humidity and highs from 22 to 24C (72-75F).

Terrible flooding continues in Texas and Oklahoma from the remains of Tropical Storm Bill. Over 1 foot of rain fell just in the overnight period. More rain is forecast today.(Twitter @Ginger_Zee)

Tropical Storm Bill
Bill, the second tropical system of this young season moved inland near Matagorda Island, Texas on Tuesday. The storm has been downgraded to a depression moving slowly northeast over Oklahoma this morning. Bill brought rough surf and some coastal flooding to the Texas Gulf Coast, but the biggest threat continues to be from heavy rain. The region has been saturated so far this month with additional rainfall of over 200mm (8 inches) falling from Bill. Severe flooding is occurring in portions of northeast Texas into Oklahoma and spreading northeast into the Ohio Valley. Some of that moisture will make it into southern New England by Sunday and even enhance the showers and storms forecast for southern Quebec. At this time it looks like the heaviest rain will remain south of Montreal over New England.
