The Agricultural Benefits of Lightning

I see enough sticky sunshine for 80s Sunday and Memorial Day, definitely beach and lake-worthy. How wet? Models print out 1-3" rains for central and northern Minnesota by Tuesday. Check the blogs for more details. -Todd Nelson

Historic Flooding on the Rainy River Basin

"High water levels are occurring across the Rainy River Basin in far northern Minnesota and adjacent parts of Ontario. This is a historic flood that has already exceeded the records set in the 2014 flooding, and will likely break the current all-time records. It will take a long time for these levels to decrease once they peak (crest), and those experiencing flooding should be prepared for weeks of high water levels into June. As of May 25, many of the major tributaries upstream (like Basswood River, Vermilion River, Kawishiwi River) have crested and are beginning to drop. However, this will only slow the rise of Namakan/Kabetogama and Rainy Lake - continued rises are still anticipated in the coming days: Namakan Lake and Kabetogama Lake are currently at 1122.0 ft (341.99 m), which is 17.7 inches (45 cm) above the 2014 peak level. A rise of 5 to 7 inches (12-19 cm) is expected between May 25 and June 1 with continued rises into mid June possible. At this rate, Namakan Lake will reach the all-time record high level of 1122.8 ft (342.24 m) set in 1916. Rainy Lake is currently at 1111.7 ft (338.85 m), which is 4 inches (11 cm) above the 2014 peak. A rise of 11 to 13 inches (27-33 cm) is expected between May 25 and June 1, with continued through at least mid June. At this rate, Rainy Lake is expected to break the all-time record high level of 1112.95 ft (339.23 m) set in 1950."

The Agricultural Benefits of Lightning
By Paul Douglas

Thunderstorms get a bad rap. A "threat" of storms, a "risk" of thunder and lightning. Of course any thunderstorm, even one that isn't severe with large hail and damaging winds, is capable of dangerous lightning strikes. But lightning also zaps nitrogen molecules in the air, allowing nitrates to be carried to the ground in rain. If anyone asks, lightning is a "super fertilizer".

Keep that in mind later this weekend when you're chased indoors by growling skies. Showers and a few thunderclaps early today give way to PM sunshine. It should dry out later today. A more unstable and volatile atmosphere ignites strong to severe storms late Sunday, and I do expect some watches and warnings. Another spirited round of storms may arrive late Monday.

On the positive side, I see enough sticky sunshine for 80s Sunday and Memorial Day, definitely beach and lake-worthy. How wet? Models print out 1-3" rains for central and northern Minnesota by Tuesday.

Cooler, drier(quieter) weather returns later next week. Have fun!

Climate Stories

(NOAA/The Minnesota Star Tribune)

"New Research On Tidal Flats Is 'Wake Up Call' For US Coastal Communities"

"About 29 percent of the United States' population live in coastline counties – more than 41 million are in Atlantic counties. This high population density poses a critical challenge to sustainable developments in coastal areas. Tidal flats, which make up coastal wetlands, are facing unprecedented challenges because of increased human activities. They are widely recognized as sentinels of coastal environment change. Importantly, they are the guardians for beachfront communities as they can largely mitigate destructive forces from the ocean. Without them, coastal communities are more vulnerable. Currently, there isn't an effective way to identify and quantify the interactions between urban areas and tidal flats, which is essential to preserve the nation's coastal communities. Moreover, existing research is limited to individual cities, which doesn't provide the big picture."

"Late May meteor shower has potential to become a major 'meteor storm'"

"The month of May could come to an end with a spectacular sky show — or a dud. That's what astronomy experts are saying about a fairly new meteor shower known as Tau Herculids, which is expected to be visible during the late-night hours on Monday, May 30, into the early-morning hours on Tuesday, May 31, 2022. How visible? That's the big question. Experts say this meteor shower is not one of the reliable ones that appears every year during the same general time frame, but it is forecast to come into view from our planet at the tail end of Memorial Day night. And some believe the Tau Herculids shower has the potential to become a rare "meteor storm," potentially producing hundreds of meteors — maybe as many as 1,000 per hour — for a short time."

"Photographer Captures the Many Colors of the Full Moon Over 10 Years"

"In a unique lunar composite that took ten years to complete, Italian teacher and astrophotographer Marcella Giulia Pace captured all the different colors she observed of a full Moon. Pace teaches at a primary school in Italy but also pursues her passion for astronomy, mountains, and optical illusions. Some of her astrophotography work has been published internationally and recognized in awards, like the Astronomy Photographer of the Year, organized by the Royal Museums Greenwich. Have collected a diverse set of full Moon shots over the past ten years, Pace brought them all together in one striking composite that showcases the many different faces, colors, and even shapes of the Earth's only natural satellite."
