Weather Outlook For Thursday
High temperatures on Thursday will warm into the 70s and lower 80s across much of the state, which will be slightly above average for most locations. With mostly sunny skies, Thursday will be one of the nicest days of the week, enjoy! Note that temperatures across central and western North and South Dakota will be nearly 10F to 20F above average.
UV Index for Thursday - HIGH
Mild temperatures and mostly sunny skies will likely have many spending more time outside on Thursday. Keep in mind that the UV Index will be considered HIGH across much of the state of Minnesota, which means that it will only 25 to 30 minutes or less to burn unprotected skin. With that said, if you are planning on spending any extended length of time outside, make sure you wear appropriate attire and lather on the sun block!
"How Do the Chemicals in Sunscreen Protect Our Skin from Damage?"
"Recognition of the risks posed by UV rays has motivated scientists to study what’s going on in our cells when they’re in the sun—and devise modern ways to ward off that damage. The good news, of course, is that the risk of skin cancer and the visible signs of aging can be minimized by preventing overexposure to UV radiation. When you can’t avoid the sun altogether, today’s sunscreens have got your back (and all the rest of your skin too). Sunscreens employ UV filters: molecules specifically designed to help reduce the amount of UV rays that reach through the skin surface. A film of these molecules forms a protective barrier either absorbing (chemical filters) or reflecting (physical blockers) UV photons before they can be absorbed by our DNA and other reactive molecules deeper in the skin."

In 2014, more than 13,000 people visited the emergency room because of a heat-related illness such as heat stroke, according to data from the Centers for Disease Control. And on average, about 675 people die in the U.S. every year from heat-related illnesses.
Heat stroke is the most severe form of heat-related illness. It’s less common than other issues such as heat exhaustion (characterized by heavy sweating, weakness, cold, pale or clammy skin, fainting, a fast or weak pulse, and nausea or vomiting) or heat syncope (fainting). But heat stroke can happen quickly, to anyone, and can result in irreversible damage or death.

PRELIMINARY 2017 Tornado Count
According to NOAA's SPC, the PRELIMINARY 2017 tornado count is 942 (through May 30). Note that is the most active year for tornadoes since 2011, when there were nearly 1,400 tornadoes. Keep in mind there was a major tornado outbreak in the Gulf Coast region from April 25-28, 2011 that spawned nearly 500 tornadoes, some of which were deadly. That outbreak is known as the Super Outbreak of 2011 and has gone down in history as one of the biggest, costliest and one of the deadliest tornado outbreaks in history.
According to NOAA's NCDC, June is the 2nd busiest month for tornadoes behind May across the country, averaging 243! Note that most of these tornadoes occur across the Plains from Texas to Nebraska, which is also in a region known as "Tornado Alley". As it stands now, May was the busiest tornado month of the year thus far with a preliminary total of 278.
"Understanding tornadoes: 5 questions answered"
We asked meteorology professors Paul Markowski and Yvette Richardson to explain why tornadoes form...
1. Where are tornadoes most likely to occur?
2. How do actual tornadoes form?
3. How precisely can we predict tornado strikes?
4. What should I do during a tornado warning?
5. Is climate change making tornadoes bigger or more frequent?

Weekend Weather Now Looks A Bit More Promising
By Paul Douglas
The world isn't ending, not yet, but it is warming. That's not from a much-maligned climate model but based on actual observations.
But it's human nature to react to day-to-day weather, not slow shifts in climate.
"But Paul, wasn't it hotter in the 1930s? We had a Dust Bowl don't you know!" On May 31, 1934 the mercury hit 106F in Minneapolis, 107F at St. Paul and 110F at Rush City! Careful analysis shows that record heat (several years when 100s were prevalent) were regional in scope. It wasn't a global phenomenon, but a heat spike limited to the Great Plains and central USA.
No heat waves are brewing, but 80s and sticky dew points topping 60F are likely by Friday and Saturday. This sudden summer surge ignites a few strong to severe T-storms, especially Friday night into Saturday morning. Sunday still looks like the drier day with a drop in humidity and low 70s.
According to NOAA only 4 percent of the USA is in drought right now. That's the lowest percentage since regular observations were started in 2000. That compares to 65 percent in September, 2012. Good news, right?
THURSDAY: Warm sunshine. Winds: S 5-10. High: 80
THURSDAY NIGHT: Mostly clear and quiet. Winds: SE 5. Low: 60.
FRIDAY: Some sticky sun, strong T-storms late. Winds: SE 7-12. High: 83
SATURDAY: Unsettled, more showers, T-storms. Winds: NW 8-13. Wake-up: 64. High: 81
SUNDAY: Drier and less humid with some sun. Winds: NE 7-12. Wake-up: 61. High: 73
MONDAY: Patchy clouds, stray showers? Winds: NE 7-12. Wake-up: 55. High: 70
TUESDAY: Sunny pleasant. Winds: NE 5-10. Wake-up: 52. High: 75
WEDNESDAY: Blue sky, warming up. Winds: E 5-10. Wake-up: 55. High: 79.

Weather Outlook for Thursday
Winds will finally be a little tamer across the region on Thursday. Instead of gusty west to northwesterly winds, we will have more of a southerly wind, which will help to pump warmer air into the region through the end of the week!
Thursday will be another bright, sunny day across the region with only a few clouds drifting in across the southerly part of the state late in the day. Enjoy it because clouds will be on the increase Friday through the weekend with widely scattered showers and storms then.
5 Day Precipitation Outlook
According to NOAA's WPC, the next several days could produce areas of locally heavy rainfall in the Eastern half of the country. Some locations could see as much as 1" to 2"+ through early next week, while areas in the Southwest will stay dry.
"Climate change is literally keeping us up at night"
"Rising temperatures caused by climate change seem to be disrupting America’s sleep patterns, according to a new study. A temperature increase of 1.8 degrees Fahrenheit causes three bad nights of sleep per 100 individuals per month. Across the United States, that amounts to 9 million sleepless nights a month and 110 million nights each year. “Our study represents the largest ever investigation of the relationship between sleep and ambient temperature,” the authors wrote, “and provides the first evidence that climate change may disrupt human sleep.” Scientists have long known that a comfortable body temperature is key for a good night’s sleep. But this research is the first to find a correlation between hotter-than-usual nights and an increase in self-reported sleeplessness. The findings were published May 26 in Scientific Advances."

"Climate change could make cities 8C hotter – scientists"
"Combination of carbon emissions and ‘urban heat island’ effect of concrete and asphalt gives rise to worst-case scenario by end of 21st century. Under a dual onslaught of global warming and localised urban heating, some of the world’s cities may be as much as 8C (14.4F) warmer by 2100, researchers have warned. Such a temperature spike would have dire consequences for the health of city-dwellers, rob companies and industries of able workers, and put pressure on already strained natural resources such as water. The projection is based on the worst-case scenario assumption that emissions of greenhouse gases continue to rise throughout the 21st century. The top quarter of most populated cities, in this scenario, could see temperatures rise 7C or more by century’s end, said a study in the journal Nature Climate Change. For some nearly 5C of the total would be attributed to average global warming. The rest would be due to the so-called “urban heat island” effect, which occurs when parks, dams and lakes, which have a cooling effect, are replaced by concrete and asphalt – making cities warmer than their surrounds, the researchers said."

"Research uses heat to predict species most threatened by climate change"
Climate change is a threat to all species, but which species will be under the greatest threat? The question is at the centre of research by a Monash University biologist Dr Vanessa Kellermann, who examines heat resistance – or 'thermal history' - to determine which species will suffer more as a result of climate change. The latest development in Dr Kellermann's work was published recently in Proceedings of the Royal Society B. "Getting accurate predictions of a species' risk to climate change is no easy task," Dr Kellermann said. "One way is to take species from the field and estimate heat resistance and see how close this estimate is to future climate projections," she said. The closer a species' heat tolerance is to maximum temperature of the environment the more at risk a species is to climate change. However, estimates of heat tolerance might be influenced by the environment a species is collected from.
