July 24 in Minnesota Weather History. Source: MPX office of the National Weather Service:
2000: An F4 tornado hits the town of Granite Falls. One person is killed and there is 20 million dollars in damage.
1915: Frost hits northeastern Minnesota.
Camping in the North Woods can be a transcendent experience, at one with nature, disconnected from the rat race back home. Until severe thunderstorms turn those majestic towering pines into weapons of mass destruction.
Every summer the question arises: how do I protect myself when I'm cowering in a tent, trying to furiously dig a tornado shelter with a spoon? It's best to ride out storms in a shelter or even your vehicle. If none is available a cave or outcropping of rocks offers some protection against falling trees. There's no perfect solution.
Smartphone Doppler radar and warning apps don't always work, but NOAA Weather Radio has great reception statewide, even up in the BWCA. Take a portable radio and monitor the weather to lower the risk of unpleasant and dangerous surprises.
Storms rumble across the region this morning as warmer, stickier air pushes back into Minnesota. Plan your lake adventure for tomorrow - the sunnier, warmer, drier day of the weekend.
Southwest winds Saturday turn around to northwest Sunday - as temperatures fall through the 70s with a few windblown showers.
Next week looks dry and relatively comfortable; 80s returning by late week. Not a heatwave in sight.

- Move to the campground shelter house. Get on your knees and cover your head.
- If there is not a shelter house, evacuate your tent or camper and lie flat in a depression, such as a ravine, and cover your head with your hands.
- Never get in your vehicle to escape a tornado!
Lightning, Wind and Hail:
- If tenting, move to the shelter house or your hard-topped vehicle.
- If no shelter is available, seek refuge in a cave or under a thick grove of trees that are taller than your tent.
- Never camp next to streams, creeks, or rivers as heavy rain can cause water levels to rise rapidly.
- Never cross rain swollen creeks, rivers, or streams as the under-currents will carry you downstream.
- If flash flooding does occur, move to higher ground immediately!

Scientists Identify Potential Tipping Point. Here's an excerpt of a story at Nature World News that got my attention: "Scientists have long been concerned that global warming may push the Earth's climate system past a "tipping point," and a new study from Oregon State University (OSU) may have finally identified that threshold. According to the research, synchronization of climate variability in the North Pacific and North Atlantic Oceans is that tipping point - where rapid melting of ice and further warming may become irreversible. This is what happened a few hundred years before the rapid warming that took place at the end of the last ice age about 15,000 years ago..."

Neil DeGrasse Tyson: "Cherry-picking Your Science Because It Conflicts With Your Philosophy?" Salon has an interview with the host of "Cosmos"; here's an excerpt: "...In science, when you perform experiments and observations, and when the experiments and observations begin to agree with one another, and they’re conducted by different people — people who are competitive with one another, people who are not even necessarily in your field but do something that relates to your field — you start seeing a trend. And when that trend is consistent and persistent, no matter who’s doing the experiment, no matter where the experiment is being done, no matter whether the groups were competitive or not, you have an emergent scientific truth. That truth is true whether or not you believe in it...."
