Meteorology: A Blend of Science and Art
Today should, in theory, be sunnier than yesterday with a shot at 80F. More clumps and clusters of thunderstorms bubble up tonight into Thursday; a few may be severe over southwest Minnesota. I still see showers for the Fishing Opener; maybe heavier, steadier rain Saturday night. A wet start Sunday gives way to clearing by afternoon. Check the blog for more details. -Todd Nelson
"No Mow May has captured the public's attention in the last few years. The idea of not mowing a lawn during the month of May in order to promote flowers for early season pollinators was first promoted by a research paper that has since been retracted. But there is still quite a bit of public interest in the initiative. Several cities in Minnesota have scaled back mowing ordinances for the month of May and have even created lawn signs for promoting the movement. And people have reached out to me to see if I would support a mandate outlawing mowing in May."

"2023 Minnesota Fishing Opener"
"Across Minnesota, 2023's ice-out dates ranged about a week to ten days behind the median in general. Here's median dates calculated since 1950. The 2023 Minnesota Governor's Fishing Opener will be in the Greater Mankato Area. The ice out for lakes in the Mankato area for 2023 ranged from April 10-14. Lake ice out was making a steady progress northward during the first week of May. Ice-choked lakes have dogged fishing openers of the past, including as recently as 2013. The 1950 opener was one of the worst known, with iced-over lakes extending to Mille Lacs, Osakis, and the Brainerd Lakes area. That year produced many of the late ice-out records for lakes with long records. Other years with ice on northern lakes include: 1966, 1979, 1996, 2008, and 2009. Minnesota's Fishing Opener weather can be variable in every sense of the word. We have seen hot, cold, wet, dry, stormy and even snowy. With such a large state and so many lakes, we have had years that were seemingly perfect in one area, only to be blustery and miserable in another."

MN Fishing Opener Forecast
Here's the weather outlook for Saturday's MN Fishing Opener across the northern half of the state. Note that it can still be very chilly at this time of the year and there have been a few years in the past that have had snow falling across the state. This year, we won't have any snow to worry about, but there will be areas of showers and perhaps a few thunderstorms. Sunday could be a little warmer, but it will depend on how much sunshine we can manage. Latest model trends are trying to hold the clouds and showers in place through the day Sunday now too. Stay tuned...

Meteorology: A Blend of Science and Art
By Paul Douglas
Breaking news: no matter how much weather models improve (better math, more data fueling the simulations) the forecast will never be perfect. Thank you chaos theory. Natural cycles and oscillations flavored by a warming climate with local influences from water and mountains? An unsolvable Rubik's Cube.
Things have improved. There is now some skill looking out 7-10 days. We will almost always see the larger, more dangerous tornadoes, but small spin-ups are more problematic. A flood or hurricane or blizzard with no warning? Probably not.
During the warm season the daytime high is a function of how much sunshine we see. Today should, in theory, be sunnier than yesterday with a shot at 80F. More clumps and clusters of thunderstorms bubble up tonight into Thursday; a few may be severe over southwest Minnesota.
I still see showers for the Fishing Opener; maybe heavier, steadier rain Saturday night. A wet start Sunday gives way to clearing by afternoon.
Pro tip: Sunday is Mother's Day. Really.

"Heads up! These Special Six Clouds Linger In Our Skies Everyday"
"Puffy cumulus and drab stratus are mainstays in the scenery of our everyday life, but there are some extraordinary clouds that lurk above our heads on a regular basis. Clouds play a starring role in the background of our lives, so much so that it's noteworthy when we get to gawk at the spectre of a crystal clear sky. Every cloud is worthy of a gaze to admire nature's artwork, but there are some clouds that are truly remarkable. Take a look at the sky the next time you're outside, and you might catch a glimpse at one of these six fantastic and special clouds. Winds don't blow in a straight line as they race above our heads. Winds twist and turn as they zip around the jet stream, and they'll rise and fall as they encounter storms and mountains in their path. That rising and falling motion often leads to wave clouds forming downwind of mountain ranges. Wave clouds are similar to the ripples that result from stones jutting up out of a stream. Winds blowing up and over a mountain range continue oscillating up and down as they flow away from the rough terrain."
"El Niño ripple effects may extend to hurricane season"
"With an El Niño likely taking shape in the equatorial tropical Pacific Ocean, forecasters are already taking into account the likely knock-on effects. Why it matters: Such an event may alter global weather patterns for at least the next six months to a year, including by limiting the number of Atlantic tropical storms and hurricanes this upcoming season. Driving the news: Two ripple effects — known to meteorologists as "teleconnections" — that El Niño is associated with are already becoming evident. First, El Niño events can inhibit Atlantic tropical storm and hurricane formation by increasing winds in the upper atmosphere over the tropical Atlantic. Such wind shear can tear apart incipient storms before they can strengthen. Zoom in: According to a new outlook from the University of Pennsylvania, the 2023 Atlantic hurricane season is likely to feature between 12 and 20 named storms, with a "best guess" of 16. This is slightly above the 30-year average of 14 named storms. The outlook took into account unusually high ocean temperatures in the tropical Atlantic, and the likelihood of at least a mild-to-moderate El Niño event during the summer and into the fall, among other factors."
"Long Blackouts Are Up to 50 Times More Likely in Parts of the U.S."
"Not all power outages in the U.S. are created the same. Populations that are already socially vulnerable are being exposed in some areas to high levels of threatening blackouts—while climate change is making long power outages much more likely, according to new research published in Nature Communications.A power outage that lasts just a few minutes can be an inconvenience, but one that goes on for hours can be deadly. People who rely on medical equipment like ventilators, oxygen machines, and home dialysis are threatened by every additional hour without electricity; during an intense heat wave or serious winter storm, not being able to turn on your air conditioner or electric heat could be life-threatening. As our planet continues to warm and storms and heat waves get more intense, our electric grid is also feeling the strain: reports of weather-related power outages between 2011 and 2021 were 78% higher than in the previous decade, according to the nonprofit Climate Central."
