July 19 in Minnesota Weather History:

1909: 10.75 inches of rain fell in 24 hours at Beaulieu in Mahnomen County. This record would stand for over 50 years. Bagley received an estimated 10 inches.
Monday Hot Front
The weather has always been extreme. The notion of "average weather" is a statistical pipe-dream; it rarely happens in real life.
But tracking daily weather over the last 40 years I've noticed an increase in the frequency and intensity of weather extremes, not just here at home, but worldwide. Insurance companies and the Department of Defense are tracking these same trends; an apparent spike in instability, volatility and weather-whiplash.
Here's another example: factoring in dew points in the mid-70s and temperatures in mid-90s tomorrow's heat index could reach 100-105F. An Excessive Heat Watch is posted. That's one week, to the day, after a miniature vortex of October-like air had Minnesotans reaching for jackets & sweatshirts. From wind chill to heat index in 7 days; a 60 degree jump in apparent "feels-like" temperature? That's highly unusual for mid-summer.
Expect more sun (and heat) today, the warm-up act for Monday's scorcher. T-storms Monday night and Tuesday may turn severe; the best chance of hail and damaging winds up north. We cool off by midweek before another warm surge sparks T-storms next Friday.
Tomorrow? A subtle (yet blunt) reminder that summer heat usually peaks in mid-July.
...DANGEROUS COMBINATION OF HEAT AND HUMIDITY POSSIBLE ACROSS THE TWIN CITIES METRO MONDAY AFTERNOON AND EVENING... AN EXCESSIVE HEAT WATCH IS IN EFFECT FOR MONDAY AFTERNOON AND EVENING FOR THE TWIN CITIES METROPOLITAN AREA. HIGH TEMPERATURES ARE EXPECTED TO REACH THE LOWER 90S MONDAY AFTERNOON. THIS COMBINED WITH DEW POINTS IN THE MIDDLE 70S WILL RESULT IN HEAT INDICES REACHING 105 DEGREES. IN ADDITION...IT WILL REMAIN QUITE WARM MONDAY NIGHT WITH LOWS IN THE MIDDLE 70S.
