An unseasonably strong area of low pressure will move from the northern US plain states into southern Manitoba over the next 48 hours. This storm will push a surge of warm and humid air from eastern Saskatchewan across the Great Lakes and into Quebec this week. Along the path of the storm very strong thunderstorms are likely, with heavy rain, up to 30mm behind the system. There is an elevated risk of large hail and tornadoes across eastern Saskatchewan and southern Manitoba today into tonight. Already this morning watches and warnings are on place across the southern Prairies. Temperatures will soar into the low 30's (low to middle 90's) from Manitoba across southern Ontario and into southwest Quebec this week. Humidex readings will approach 40C (104F) in many locations including Toronto and Montreal.
MONTREAL
For the specifics, we are looking at hazy sunshine in Montreal through Thursday with daytime highs near 30C (86F) and overnight lows near 21C (70F). Areas of fog are reported this morning in the region, and may form each morning this week. Each afternoon into the early evening there is a 40 per cent change of scattered thunderstorms, some may be strong. A cold front will bring more widespread showers and thunderstorms by Thursday. Cooler and dryer weather will return to southern Quebec by next weekend.
