Don't like the weather - just wait a few minutes

Water from Lake St Louis continues to produce minor flooding in shoreline communities in and around Montreal. Above, flood waters creep in Summerlea Park in the borough of Lachine on Wednesday. The municipality has raised the level of the walking path as well as built some reinforcements to hold the water back.(Valley Weather Photo)

Scattered thunderstorms are possible in Montreal and across southern Quebec today, as a warm and humid air mass is in place. Some of the storms may produce heavy rain and gusty winds. Temperatures will be near 27C (81F), along with elevated humidity levels. Temperatures will be slightly cooler tonight and into the weekend, with lows down to 16C (61F), and highs both Saturday and Sunday near 24C (76F). Unfortunately the weekend will display the same weather we have become accustom do for the last few months. I hate to reuse the same word over and over again, but unsettled comes to mind. The atmosphere will be busy, changing frequently and quickly, with fair skies in the morning, building instability, and showers or thunderstorms in the afternoon. This type of weather will prevail into early next week.

Where is all the hot air? 
If you want heat, go western North America. However, the sunny, hot weather comes at a price. Wildfires are running rampant from California to Montana and in especially hard-hit Colorado. Heat emergencies have been declared in many communities. The hot air has arrived in Canada, from southern interior B.C., eastward into Alberta and Saskatchewan. Temperatures this week have been in low to middle 30's, and may approach 40C along the Montana border by next week. Heat warnings have been issued by Environment Canada for several locations in Alberta and southwest Saskatchewan.

As we head into summer vacation time in Quebec and Ontario, please be extra careful around any body of water. Levels on the Great Lakes, Ottawa and St Lawrence Rivers continue to run very high. When you add any wind to the mix, the water can easily overwhelm a boat, or make swimming dangerous. Minor shoreline flooding also continues in several communities.
