Shower Risk Today – A Fine Weekend Coming
Things that may not come back anytime soon: high-fives, random salad bars, grocery store food samples, standing in line and mosh pits. I’m going to miss the mosh pits.
I suspect the new normal will be anything but. There is one saving grace: our yards will be better maintained than anytime in our history. Nothing like power-mulching, or baking, or loitering on a Zoom call, to help you maintain your sanity.
Today won’t be nearly as extraordinary as Thursday was, with a few hours of showers and T-storms expected. The good news: a dry weekend is brewing, with afternoon daytime highs flirting with 70 degrees. Those low-humidity, bug-free, thunder-optional days you were daydreaming about are imminent.
Soak it up, because we will cool off next week, with showery rains Monday and Thursday – a few days with highs in the 50s.
The combination of Tuesday’s soaking, recent sunshine and warming temperatures is leading to an explosion of green. After our rough winters I’m amazed anything comes back to life!
Dueling Models. There’s a fair amount of agreement between ECMWF (top) and GFS (bottom), showing a temperature correction next week with 50s and low 60s. Is the frost/freeze risk over the Twin Cities this spring? Probably, yes. MSP Meteograms: WeatherBell.
Why Do So Many Anchors Sound Alike? A question I’ve wondered about all these years. Mental Floss has a good explainer: “…The more contemporary practice of sounding linguistically neutral is often referred to as having a General American accent—which is a bit misleading, since there’s really not much of an accent at all. Also referred to as Standard American, Broadcast English, or Network English, General American was a term first used in the 1920s and ’30s by linguists who wanted to isolate a more widespread accent than the New England or Southern dialects. The scholar George Philip Krapp used the phrase in his 1925 book The English Language in America; linguist John Kenyon referred to it in his 1930 title American Pronunciation, where he insisted that 90 million Americans spoke General American…”
German Doctors Pose Naked to Protest Protective Equipment Shortages. CNN reports on the tactics some doctors are using to raise public awareness: “A website apparently featuring photos of German medical workers is calling attention to the working conditions and protective equipment needed by frontline workers amid the coronavirus pandemic. The website, “Blanke Bedenken,” shows photos of apparently nude people, some of whom are partially obscured by medical equipment, paperwork and other props, including stethoscopes, anatomical skeletons and even toilet rolls. “We are your GPs. To be able to treat you safely, we need protective gear…”

May 1, 1966: Winter makes a last stab at Minnesota with a low of 5 at Cook. A widespread freeze hits the rest of the state.
May 1, 1935: An unusually late snow and ice storm hits east central Minnesota. The heaviest ice accumulations are between St. Paul and Forest Lake and westward to Buffalo in Wright County, with accumulations of 1 to 1.5 inches on wires. The downtown Minneapolis weather bureau records 3 inches of snow.

In Fast-Warming Minnesota, Scientists are Trying to Plant the Forest of the Future. The Washington Post has a powerful story about the changes underway in Minnesota; here’s a clip: “A Washington Post analysis of historical temperature data found that seven counties in Minnesota have warmed more than 2 degrees Celsius since the late 19th century — about twice the global average. Winters here have warmed even faster, with 59 of the state’s counties — about two thirds — eclipsing the 2C threshold during the months of December through February. Minnesota is home to a landscape like none other in the United States. It has the boreal forests to the north, with their stately conifers and the moose and lynx that roam them; temperate forests in the middle, dominated by deciduous trees such as oak and maple; and prairie stretching to the south and west. But rising temperatures are altering those boundaries. Experts in the state have testified about what is in store if temperatures continue to rise: more heat-related deaths, lower crop yields, damaging deluges and floods, a surge in pests, increasing drought and worsening air quality…”

Climate Change Threatens Drinking Water Quality Across the Great Lakes. Discover Magazine has a post that’s worth your time; here’s an excerpt: “…The culprit was a combination of high nutrient pollution — nitrogen and phosphorus, which stimulate the growth of algae — from sewage, agriculture and suburban runoff, and high water temperatures linked to climate change. This event showed that even in regions with resources as vast as the Great Lakes, water supplies are vulnerable to these kinds of man-made threats. As Midwesterners working in the fields of urban environmental health and climate and environmental science, we believe more crises like Toledo’s could lie ahead if the region doesn’t address looming threats to drinking water quality…”

America’s Northernmost City Just Recorded Its First Record-Low Temperature in 13 Years. Capital Weather Gang has some much-needed perspective: “…Sea ice is perhaps the greatest influencer of the weather in Utqiagvik; the hasty retreat of sea ice and the emergence of exposed ocean waters in recent years have amplified Utqiagvik’s climate-driven warming rate even more. So while Wednesday’s morning low did beat out a previous record by a mere degree, it’s negligible in the face of 112 record high temperatures tied or broken in the time since Utqiagvik’s last record low. “In baseball, you don’t see 112 to 1,” Thoman said. “That’s a blowout.” Utqiagvik is ground zero for climate change in the United States, with the city rapidly warming more than five degrees in the past century…”

Meteorologists Say 2020 On Track to be Hottest Year Since Records Began. Where have we heard that before? Oh yeah – just about every year since 2000. I’m sure this must all be a cosmic coincidence. Here’s the intro to a Guardian post: “This year is on course to be the world’s hottest since measurements began, according to meteorologists, who estimate there is a 50% to 75% chance that 2020 will break the record set four years ago. Although the coronavirus lockdown has temporarily cleared the skies, it has done nothing to cool the climate, which needs deeper, longer-term measures, the scientists say. Heat records have been broken from the Antarctic to Greenland since January, which has surprised many scientists because this is not an El Niño year, the phenomenon usually associated with high temperatures. The US National Oceanic and Atmospheric Administration calculates there is a 75% chance that 2020 will be the hottest year since measurements began…”

More Days of Heavy Rain. Climate Central takes a look at the trends; here’s an excerpt: “...If the old adage is anything to go by, May should bring plenty of flowers (to much of the country)! While seasonal weather patterns like April showers seem to endure, long-term averages show that climate change is fundamentally changing other aspects of precipitation—making heavy rainfall events more common and more intense. In recent years, an increasing percentage of precipitation has come from intense, single-day events. Climate Central analyzed how heavy rain events are changing in U.S. cities since 1950. Since the amount of rain that falls in a heavy rain event varies dramatically from the Desert Southwest to the downpours of Florida, this analysis calculated trends in ½, 1, 2 or 3-inch events, as appropriate to the location (see Methodology for more details). Over the past 70 years, 79% (191) of the 242 stations analyzed recorded an increase in heavy rainfall...”
Tropical Deforestation Releases Deadly Infections. Ah, science. Climate News Network is connecting the dots: “As forest destruction continues unabated in Brazil, scientists are alarmed that, as well as spurring climate change, it may unleash new and deadly infections on humankind. There is growing awareness that large-scale tropical deforestation, as in the Amazon, not only brings disastrous consequences for the climate, but releases new diseases like Covid-19 by enabling infections to pass from wild animals to human beings. As one well-known Amazon scientist, biologist Philip Fearnside, puts it: “Amazon deforestation facilitates transmission both of new diseases and of old ones like malaria…”
How Concern Over Climate Change Correlates with Coronavirus Responses. I’m sensing a trend here. Here’s a clip from Morning Consult: “Adults who say they are not concerned about climate change are less likely than the general public to be taking personal actions to mitigate the effects of the coronavirus, new Morning Consult data shows. And in contrast, climate-concerned U.S. adults are more likely to be taking these actions, which include wearing masks in public, social distancing and disinfecting the home and personal electronics. In a poll conducted April 14-16, 54 percent of climate-concerned respondents said that they have “always” worn a mask in public spaces such as grocery stores or parks over the last month, whereas just 30 percent of the climate-unconcerned said the same — a 24-point gap...”
Fact Check: How Electric Vehicles Help to Tackle Climate Change. Zeke Hausfather has an illuminating post at CarbonBrief: “Here, in response to recent misleading media reports on the topic, Carbon Brief provides a detailed look at the climate impacts of EVs. In this analysis, Carbon Brief finds:
- EVs are responsible for considerably lower emissions over their lifetime than conventional (internal combustion engine) vehicles across Europe as a whole.
- In countries with coal-intensive electricity generation, the benefits of EVs are smaller and they can have similar lifetime emissions to the most efficient conventional vehicles – such as hybrid-electric models.
- However, as countries decarbonise electricity generation to meet their climate targets, driving emissions will fall for existing EVs and manufacturing emissions will fall for new EVs.
- Comparisons between electric vehicles and conventional vehicles are complex. They depend on the size of the vehicles, the accuracy of the fuel-economy estimates used, how electricity emissions are calculated, what driving patterns are assumed, and even the weather in regions where the vehicles are used. There is no single estimate that applies everywhere...”
