Too Much Warning?
There's a nagging, dangerous perception that big, Oklahoma-size tornadoes can't hit the Twin Cities. Although rare, violent, long-track tornadoes are possible, especially in May.
On May 6, 1965 a swarm of 6 major tornadoes, 4 of them EF-4 super-twisters, hit the metro area. Fridley experienced 2 EF-4's, just 85 minutes apart. WCCO-AM saved countless lives with their coverage, but 13 people died, 683 were injured. These were the last EF-4's to strike the metro.
Now comes new research suggesting that longer lead times, 30 or 40 minutes, compared to a national average of 13 minutes, may lead to poor, even reckless decisions; people try to drive away from the approaching instead of sheltering in place, which greatly increases the risk. You don't want to be sitting in a car or truck when a tornado crosses the interstate. Bad idea.
Live TV video of an approaching tornado gets people moving MUCH faster than hearing a tornado warning. Seeing is believing. And motorcycle helmets may offer the best protection from head and neck injuries. Details on my blog below.
Nothing violent in sight, just a gray Saturday with a warming trend later this week. 60s return tomorrow; 70s by next weekend as a ridge of warm high pressure stretches north across the Plains. I could see 80 degrees in about a week.
A growl of thunder is possible Tuesday, again Friday but nothing severe is brewing just yet. Give it a couple of weeks.
1.5" at Embarrass, Kabetogama, and Ely
In addition Orr reported 3.0", Tower 2.0", and International Falls 1.9" but these were not new record totals for the date. Following the snow, the low temperature plunged to just 10°F at both Fosston and Embarrass, the coldest reading in the nation for April 23rd..."

Spring Regains Its Bounce. After a brief temperature relapse earlier this week, complete with obligatory snowflakes, milder air returns to Minnesota next week with highs in the 60s. European guidance suggests 70s, even 80s by next weekend. The best chance of a few showers and T-showers: Tuesday, again Friday of next week. Source: Weatherspark.
1) An American Motorcycle Association-approved helmet with a full face shield providing head and neck protection is the top helmet and is easily accessible. But a good motorcycle helmet can cost many hundreds of dollars.
2) Football helmet. A football helmet is designed to protect the head and face, including the sides of the head. It should be one approved for full contact. A good football helmet can cost more than $200..."

* If you've smoked at least 100 cigarettes over the course of your life you are at increased risk of COPD. Phil is a dear friend of mine (we worked together at WLOL-FM). He isn't letting COPD slow him down, but his mission is to raise awareness among the general population. Many people have COPD and they don't even realize it yet. Take the screening test from the COPD Foundation; it takes a minute or two.

What the present paper shows is that future changes to clouds will cause slightly more warming. Scientists describe clouds as a “positive feedback” on global warming. This finding is consistent with the work of Dr. Andrew Dessler. He had published work here and here showing changes in clouds are making the Earth warm more than otherwise expected..."
