Impressive lightning over Denver yesterday. (Fox News Denver)The A/C has already kicked in here at work, something that usually does not happen until late morning or early afternoon. The temperature in Montreal is at a hazy and humid 23C with a humidex already at 29C. Hot and humid air is streaming northward from the central US where triple digit heat has been baking the region for several weeks. Many locations in the southern plains have seen their warmest days since the 1980's. Oklahoma had temperatures near 110F over the weekend. Drought in the southwest continues to generate isolated sand storms, thankfully none as big as the monster one last week in Phoenix.
As far as our region goes, hazy sunshine will give way to clouds and thunderstorms by late today. Temperatures will reach 31 to 33C (88 to 92 F) in southern Quebec and eastern Ontario, and 32 to 35C (90 to 95F) in southern Ontario. Humidex values will approach 40C (104F), and into the 40's over Windsor and London where humidex advisories are in effect. Triple digit heat will spread from the southern plains into the middle Atlantic today. Meanwhile the leading edge of drier air is moving into the Midwest today. This morning strong thunderstorms and squall lines are producing wind damage from the eastern Dakotas across Minnesota and into Illinois and Indiana. Those storms will spread east today into Ohio and New York, and may graze southern Ontario. The storms in Montreal tonight will be gusty with lots of lightning, but they should not be severe. We will have to wait and see. Watch my twitter account for updates (link on upper left side of blog).
