Roughly 7 months out of the year the term "Canadian cold front" is a pejorative, a negative, cringe-worthy expletive. "Canada exports wheat, oil, hockey players and cold fronts!" But give credit where credit is due: much of America is broiling; tens of millions of our brethren wilting under a heat index above 100F. But a persistent west/northwest jet stream wind flow aloft has allowed a conga-line of (refreshing, wondrous!) Canadian cool fronts to burp south of the border, taking the edge off the heat from St. Paul to Detroit and Boston.
I'm sending a Hallmark thank you note to Canada for the comfortable, sun-scrubbed sky outside my window. A/C optional? Highly unusual for late July.
Fasten your seat belt and prepare to ride out some of the best weather of the year: 80s into next week, with occasional puffs of Canadian air keeping the dew point very tolerable - little chance of severe weather or monsoon rains. A few T-storms may pop up late Sunday, but most of the upcoming weekend will be dry and pleasantly warm.
Rainfall since June 1 is running 3.7 inches above average in the Twin Cities. No drought, no storms, no midsummer sweat. What's not to like?
