Question: Will Spring "Stick" This Time Around?
People never ask me about the Twins, foreign policy or existential truth. But they're not shy about quizzing me about the state of the atmosphere.
Here are but a handful of the questions I've received recently. "Paul, are we done with snow?" What snow? We picked up 36.7 inches last winter. Average is 54.4 inches. Flurries could still brush the Minnesota Arrowhead - but accumulating snow is behind us now.
"Paul, is it safe to plant annuals?" Yes it is. GFS guidance hints at upper 30s by late next week but the odds of a widespread metro frost are less than 1 in 10. The old adage "wait until after Mother's Day to plant tender plants" rings true this year.
We cool off into the low 60s today with a stiff north breeze, but 70s return Thursday - low 80s will spark an outbreak of shorts and T-shirts Friday. A taste of sultry summer days to come.
A stray T-shower may bubble up late Friday ahead of a cooler front, but skies clear during the day Saturday; Sunday brings peeks of sun and highs near 70.
Enjoy the dry spell; cooler, showery weather returns for much of next week.

Weather Keeps Killing, But Experts Say Deaths Preventable. Here's a clip from a USA TODAY article: "...Floods, rip currents, lightning and heat kill hundreds of people each year, but experts say almost every one of those deaths is preventable. Heat is the nation's biggest killer, striking down about 130 people each year, according to data from the National Weather Service. Rip currents sweep about 100 people out to sea annually and floods take another 100 people, the data shows. Lightning strikes kill about 25 people a year. Data from the Centers for Disease Control, which uses broader criteria for calculating cause of death, says the numbers are even worse, attributing several hundred deaths to heat and cold..."
Crude Oil is Flooding Texas Rivers. Here's the intro to a story at Grist: "Dramatic, deadly flooding is the new normal for parts of Texas and Louisiana this past year. This weekend, a single flash flood killed six people. But the damage often doesn’t end when the skies are finally clear. In Texas — a state dotted with oil wells — extreme flooding can also mean contaminated water. According to El Paso Times, chemicals and oil from overfilled wells and fracking sites have flushed into majors rivers. Texas officials have reportedly taken dozens of images of waterways polluted with crude oil and fracking chemicals, which show the “sheens and plumes spreading from tipped tanks and flooded production sites.” Affected waterways include the Sabine River on the Texas-Louisiana border, which flooded in March, and the Trinity, Red, and Colorado rivers, which flooded last year..."

Early May Tends to be Feast or Famine for Tornadoes. U.S. Tornadoes has some interesting nuggets and statistics; here's an excerpt: "...tornado climatology is an interesting thing to look at but sometimes averages can be misleading, as tornadoes do tend to come in bunches. It is not until late May and early June that consistent and often day-to-day tornado activity becomes common around the entire country. By June, the potential for a major outbreak starts to decline as the jet stream slows and becomes less variable. However, the frequency of tornado days make this a prime choice for storm chasers who are looking to play the odds for chase prospects. This also serves as a reminder not to let your guard down after the peak of outbreak season passes, especially in the northern tier of the U.S..."
Earth's New Lightning Capital in the World: 233 Flashes Per Square Kilometer A Year. Move over Congo, we have a new, electrifying winner, according to NASA and a story at Space Coast Daily: "Earth has a new lightning capital, according to a recent study using observations from the Lightning Imaging Sensor onboard NASA’s Tropical Rainfall Measurement Mission. Lake Maracaibo in Venezuela earned the top spot receiving an average rate of about 233 flashes per square kilometer per year, according to the study.Researchers had previously identified Africa’s Congo Basin as the location of maximum lightning activity..."

The Awe-Inspiring Growth of the U.S. Solar Industry. A few very interesting and encouraging statistical nuggets in a Huffington Post story; here's an excerpt: "...Solar’s costs have come down to the point that we regularly see contracts for utility-scale solar power under 5 cents per kilowatt-hour – making solar, in many cases, a cost-competitive option for utilities. Last year our country added more solar than new natural gas capacity for the first time ever – and you can bet it won’t be the last. In fact, there have been times this year when California, one of the world’s largest economies, has gotten third of its power from the sun. It hasn’t always been sunny on the road to a million solar installations. Although there is sustained double-digit market and job growth, there have also been naysayers, big-moneyed opposition, nasty electoral politics, and stumbles from an industry in its early stages..."

Sea ice affects the large scale global ocean circulation patterns as well as weather patterns. Professor Tom Mote is a hydroclimatologist and head of the Geography Department at the University of Georgia. He studies Greenland and other cryospheric processes. He says,
The long-term record of sea ice, in particular, is important to our understanding of the Arctic. Reductions in sea ice amplify warming in the Arctic by increasing the absorption of sunlight (i.e., the ice-albedo feedback). Some scientists believe that a warmer Arctic may change the path of the jet stream, altering weather over further south, including the U.S. (See this paper for a summary of the literature).Climate models have been conservative with sea ice decline. They have underestimated the amount of change in many cases..."
