30s To Begin Sunday In Northern Minnesota
It’s Labor Day weekend, and of course, we have to track some chilly morning temperatures up north! The Superior QD #4 RAWS site made it down to 30F, with 33F at the Seagull RAWS station. Meanwhile, the Ely and Eveleth airports dropped to 34F.
National Weather Forecast
There isn’t a lot of change across the country as we head from Sunday into Labor Day Monday with storms expected from the East Coast to the Southern Plains and some showers in the Pacific Northwest. Some of the rain on Monday could be heavy in the Ohio Valley and the Northeast.
You can see those potential heavy rains from the southern Appalachians to the Ohio Valley and into the Northeast over the next couple of days, with the potential of 3”+ of rain through Tuesday evening.
In the Atlantic, we are currently tracking two named systems. Hurricane Danielle continues to spin in the central Atlantic, meandering and not causing any concern to landmasses. That system will eventually get kicked off to the northeast this week. Earl is sitting north of the Virgin Islands and Puerto Rico and will slowly move north and eventually northeastward this week, curving back into the Atlantic before directly impacting land. It’s likely to pass south and southeast of Bermuda. Meanwhile, Javier has become a post-tropical cyclone in the Pacific, with the remains of the system expected to head west. And Tropical Storm Kay has formed and is expected to become a hurricane later this week before moving near Baja California.
NASA’s Megarocket Will Head Back to Garage After Second Failed Launch Attempt
More from Gizmodo: “A serious and unmanageable hydrogen leak prevented NASA from launching its SLS rocket on Saturday. Teams continue to evaluate the reason for the second failed launch attempt, but NASA says the rocket will have to return to the Vehicle Assembly Building to undergo safety checks. For rocket scientists, hydrogen is an important propellant, but it’s also a serious pain in the ass. It’s the tiniest molecule in the universe, and as such, it has a propensity to leak out through tiny gaps and cracks. Hydrogen leaks bedeviled the Space Shuttle program, and now SLS—a rocket heavily modeled after the Shuttle launch system—is likewise experiencing problems with hydrogen leaks. The most recent leak, which prevented the Space Launch System from blasting off today, was more severe than the one experienced during the first launch attempt on Monday, Mike Sarafin, Artemis mission manager, told reporters during a press briefing held earlier today.”
These rooftop solar vacuum tubes that make both electricity and heat are US-bound
More from Electrek: “UK-based solar tech developer Naked Energy’s rooftop solar vacuum tubes, which produce both electricity and heat, will soon be sold in the United States. Peoria, Illinois-headquartered ELM Companies, a US energy storage and microgrid specialist, is funding Naked Energy, along with banking giant Barclays and US venture capital firm Big Sky Partners. ELM Solar, ELM Companies’ new division, will distribute Naked Energy’s solar thermal and PV thermal products, which are called Virtu (pronounced “virtue”). ELM Solar will also distribute Virtu products through ELM Companies’ large dealer network and partnerships across the United States.”
The long, leguminous quest to give crops nitrogen superpowers
More from WIRED: “Given all that nastiness, scientists have long been on a quest to reduce agriculture’s dependence on fertilizers by giving cereal crops their own nitrogen-fixing powers. And with the rise of gene-editing technology over the past few decades, that quest has been making progress. Last month, in the Plant Biotechnology Journal, researchers described a breakthrough with rice, engineering the plant to produce more compounds that encourage the growth of biofilms, which provide a cozy home for nitrogen-fixing bacteria, much like legumes provide nodules for their partner microbes.”
