Spotty Frost This Morning - Best Chance of Salvaging a Fairly Nice Holiday Weekend?

47 F. high at St. Cloud Monday.
70 F. average high on May 18.
74 F. high on May 18, 2014.

May 18, 1980: Mt. St. Helens erupted. The smoke plume rose to 80,000 feet. The cloud circled the earth in 19 days. Brilliant sunsets were seen over Minnesota for days afterward.

The Gales of...May?

Sunday night was a vivid reminder that only the brave and foolish put their boats in the water before Memorial Day. Unless you have a sturdy lift or jet-powered sump pump. Winds gusted over 40 mph in the Twin Cities metro (tropical storm force), with 50+ mph winds out west.

Snow coated roads over the Dakotas yesterday; flurries spotted in Minnesota from Pipestone to Baudette. Hey, it gave us all something to babble about.

Gale force winds and flurries gave rise to clearing skies; dry Canadian air setting the stage for a late-season freeze over western Minnesota. It's another subtle (yet blunt) reminder to avoid the urge to plant annuals until after Memorial Day. The latest 32-degree or colder low temperature at MSP? May 24, 1925.

A few plants from Willmar to Fargo and Brainerd probably froze their buds off this morning but temperatures mellow as the week goes on. Expect generous sunshine and a dry sky into Saturday, probably the best day of the holiday weekend. Showers may pop up Sunday and Memorial Day; probably nothing severe to track. We warm up again next week as sticky air flows north; hints of sweltering evenings to come.

Yes there's something for everyone in May.

Too Close For Comfort. NOAA has issued Freeze Warnings for the Red River Valley and far western Minnesota, where winds may subside enough for a frost or freeze this morning. Winds ease later today and although the immediate metro area should avoid a frost or freeze Tuesday morning there may be some frosty issues from Willmar to St. Cloud and Brainerd.

Frost Advisory. NOAA has issued frost advisories as close to the MSP metro area as Willmar and St. Cloud for this morning. With any luck it won't be a killing freeze for central Minnesota, where enough of a breeze may linger to avoid the coldest temperatures.

Predicted 7 AM Temperatures. NOAA's NAM model suggests temperatures will dip below 32F this morning across much of the Dakotas, the Minnesota Arrowhead and northern Wisconsin. Source: AerisWeather.

Pass The Smelling Salts Please. Here is the accumulated snowfall product, showing a significant smear of accumulating snow spreading from the Rockies into the Nebraska Panhandle today and tomorrow.

Warming Trend. With some sunshine and less wind today will feel considerably better than yesterday, even with temperatures well below average. We start to return to normal by Thursday and Friday; clouds increase late Saturday with a spattering of showers Sunday and Memorial Day. There are some signs of a more significant warming the latter half of next week. Source: Weatherspark.

With Climate Change, Ticks Marching Farther and Earlier. Yes, the ticks are out in full force. Here's an excerpt of a story at Climate Central: "...But in a warming world, May is really too late to get people thinking about protecting themselves, said Richard Ostfeld, a disease ecologist at the Cary Institute of Ecosystem Studies in Millbrook, N.Y. “The nymphs used to peak in June,” he said, referring to immature ticks, which are most likely to transmit disease. “Now it’s happening in mid-May, and if you project forward with simple climate models, it’ll be early May within a couple of decades.” That’s the conclusion of a paper Ostfeld co-authored recently in the journal Philosophical Transactions B, published by Britain’s Royal Society..."

Scientists May Have Discovered a Critical Key to Predicting Volcanic Eruptions. Are we closer to a system that can predict volcanic eruptions with some degree of reliability? Huffington Post has the story; here's an excerpt: "...Understanding the triggers for volcanic eruptions is vital for forecasting efforts, hazard assessment and risk mitigation," Dr. Janine Kavanagh, a volcanologist at the University of Liverpool in England and the leader of the team, said in a written statement. "With more than 600 million people worldwide living near a volcano at risk of eruptive activity, it is more important than ever that our understanding of these complex systems and their triggering mechanisms is improved..."

Feds Say That Banned Researcher Commandeered a Plane. Well this should give you a nice, warm fuzzy as you board your next flight. Pray it doesn't get hacked. Wired has the story; here's the intro: "A security researcher kicked off a United Airlines flight last month after tweeting about security vulnerabilities in its system had previously taken control of an airplane and caused it to briefly fly sideways, according to an application for a search warrant filed by an FBI agent. Chris Roberts, a security researcher with One World Labs, told the FBI agent during an interview in February that he had hacked the in-flight entertainment system, or IFE, on an airplane and overwrote code on the plane’s Thrust Management Computer while aboard the flight..."

Climate Stories....

Global Warming Fueling Fewer But Stronger Hurricanes, Study Says. Which matches the trends of what we're seeing in the data, especially during the warm weather months: fewer storms overall, but the storms that do spin up have a much better chance of producing excessive rains from the Upper Midwest to New England. Here's an excerpt from The Capital Weather Gang: "Warmer ocean temperatures appear to be fueling more intense hurricanes at the expense of the overall number of storms, says a new study published today in Nature Climate Change. Over the past decade, studies have analyzed ad nauseam how warmer temperatures might be changing the annual number of hurricanes, or the maximum intensity. In theory, the hurricane hypothesis has always been a simple one: Tropical cyclones are fueled by warm ocean surface water, so warmer oceans should be fueling stronger hurricanes..."

May CO2 Peak Shows Trend is Up, Up, Up. Here's a clip from an update at Climate Central: "...The amount of heat-trapping carbon dioxide in the atmosphere has been measured at the observatory atop Hawaii’s Mauna Loa volcano since 1958, producing a record that shows not only the yearly maximum and minimum driven by the spring bloom and fall dieback of plants, but also the steady climb in CO2 levels every year. The last few years have seen a spate of atmospheric CO2 milestones in the Mauna Loa record: The first measurement of CO2 above 400 parts per million (ppm) in May 2013, the first month entirely above 400 ppm in April of last year, and this year will likely see several months with an average above that level..."

Shell Accused of Strategy Risking Catastrophic Climate Change. The Guardian has the article; here's an excerpt: "Royal Dutch Shell has been accused of pursuing a strategy that would lead to potentially catastrophic climate change after an internal document acknowledged a global temperature rise of 4C, twice the level considered safe for the planet. A paper used for guiding future business planning at the Anglo-Dutch multinational assumes that carbon dioxide emissions will fail to limit temperature increases to 2C, the internationally agreed threshold to prevent widespread flooding, famine and desertification..."

Shell Oil's Cold Calculations for a Warming World. Here's an excerpt of a New York Times Magazine story that made me do a double-take: "...In 2008, Shell surprised observers by announcing that it had a preferred scenario. The company would prepare for both outcomes, but for the good of the world and the good of Shell itself, it hoped for the carbon-constrained future of “Blueprints.” The oil giant awaited government action: a market signal in the form of a carbon price. But when I interviewed him four years later, Bentham admitted to me that the future, so far, was looking a lot more like the chaos of “Scramble.” We had no working international climate agreement and no real price on carbon. Instead, we had a global race for gas, coal and the last drops of conventional oil..."

What Can We Do About Climate Change? Here's an excerpt of a very interesting interview at The New York Times: "...When coal is burned to produce electricity it produces pollution that kills more than 10,000 Americans each year, and more than a quarter million Chinese. In addition it does severe damage to fish, birds and waterways. And we haven’t even gotten to its contribution to climate change. Getting off coal will by difficult. Lot’s of things are difficult. Quitting smoking is difficult. Abolishing slavery was almost unimaginable for people living in those societies. For centuries European and American economies depended on coerced labor..."

The Really Awful Truth About Climate Change. Joe Romm at ThinkProgress has the story - here's a snippet: "...No, the really awful truth about climate change is that while climate scientists, the International Energy Agency, and many others have been increasingly blunt about how dire our situation is — and what needs to be done ASAP to avoid catastrophe — much of the so-called intelligentsia keep ignoring them. The most recent example comes in a report out earlier this month from 70 leading climate experts (click here)..."
