June 23 in Minnesota Weather History. Source: NOAA.
2002: Heavy rains fell on already saturated ground on 24. 5.50 inches fell at Delano. Half of a mobile home park at Howard Lake was evacuated due to rising water.
1972: Frost across eastern Minnesota. Duluth had a low of 35 and Tower bottomed out at 32.
This is Lightning Safety Awareness Week across the USA. Odds are you've had an unpleasant close encounter with a lightning strike or two - it can be a religious experience.
It turns out the most dangerous time is at the beginning and end of a storm, when rain isn't falling. This is when people are often out on a lake or golf course, "pushing the weather", and their luck in the process.
Just because it's not raining doesn't mean there isn't a high threat of lightning, which can travel up to 10 miles from the parent thunderhead.
Lightning is lazy, often striking the tallest object in the area. NOAA data shows 37 percent of lightning fatalities since 2006 were water-related. Stay off the lake or beach when storm clouds threaten. That first growl of thunder? Head indoors.
Since 2006 81 percent of lightning victims have been men. Because men, as a rule, are more stubborn? My wife thinks so. Possibly, but more men work outside, more vulnerable to the elements.
We cool off a bit the next couple of days; a few instability showers pop up this afternoon, but dry weather should be the rule into Friday as Minnesota sees a much-needed break. Heavier T-storms fire this weekend as dew points rise; highs surging into the 80s. We may finally hit 90F next week. Yes we're due for a hot front.
A dry front would be nice too.

When large waves develop in the flow, cold Arctic air moves south (as seen here over eastern US) and warmer temperate air moves north (as seen here are central US). Such "wavy" conditions increase the chance of temperature and precipitation extremes." (Photo: NASA)
