A Significant Heat Wave Will Send Temperatures Soaring Across the U.S.
Summer isn't wasting any time.
A 'significant and extremely dangerous heat wave' is expected to send temperatures soaring across much of the United States in the coming days, stretching from the Central Plains to the East Coast, according to forecasters with the Weather Prediction Center.
'This will certainly be the first big heat wave of 2025 for the Northeast and Mid-Atlantic, as well as a large portion of the Midwest,' said Alex Lamers, a forecaster with the center, a part of the National Weather Service.
Temperatures at the end of spring have been relatively mild across the East. Mr. Lamers warned that those cooler-than-normal temperatures may mean that this sudden first burst of extreme heat is all the more dangerous because people in many areas have not acclimated to it yet.

This Essential Lawn-Mowing Tip Will Keep Your Grass From Dying in Summer Heat
Mowing the lawn during summer is a time-honored tradition and one household chore you might not think contains much nuance. To keep your grass looking sharp and green, there are fatal mistakes to avoid, especially during hot weather. Beyond supplying your grass with proper nutrients and water, these grass-cutting hacks will ensure your lawn stays healthy, even in the sweltering summer heat. With a little strategy and a few easy adjustments, you can turn your lawn from a sorry brown to a glittering green -- and do it in less time. So grab your best mower and read these four essential tips for when to mow, how to mow, and how to keep your mower happy. Read more: The gardening tips everyone needs to know. 1. Keep it long I short trim can cause damage to your lawn, especially during hotter months. Chris Wedel/CNET For some, a perfect lawn is always well-trimmed and consistently kept short. Unfortunately, while this may look nice, it can be a detriment to the overall life of your grass. During the hottest days of summer when your yard is competing with sweltering heat, blazing sun, and less rain, it's best to keep the grass around 4 inches high after a cut. That may seem long, but taller grass retains more water and has longer, healthier roots. So, you'll have to go to the golf course to see that short grass during the summer months if you want your lawn to thrive year-round. 1. Wait until the grass is dry Cicada chimneys look kind of like anthills. Russell Holly/CNET It may seem obvious during the summer when it reaches unbearable temps during the day to try and get started mowing early in the cool morning hours. But if there's still dew on the ground, you can lose time and damage your lawn. This is due to the high likelihood that wet grass will clump up in the discharge chute (that flappy thing on the side), requiring you to stop and remove the clog. Plus, your mower tires won't get great traction either and could put tracks in your yard. Instead, wait until later in the morning when the dew dries, or mow the lawn late in the day before the evening dew. Also, time your sprinklers to start up in the late evening or at night so there isn't extra moisture on the grass when you mow. Here are some more watering tips for your lawn. 3. Go slower Keep your speeds low to make mowing go fast. Alina Bradford/CNET Short on time or just want to get the chore over faster? Then going fast makes the most sense, right? But while it's tempting to go fast while mowing, it can actually create more work for you. By not taking your time and letting the mower do its job properly, there's a good chance it will leave some areas uncut and give the lawn an uneven, sloppy look. This means you'll have to take more time to re-mow it to make the lawn look correct. Instead, take the path of the turtle -- slow and steady. A slower, mid-speed mowing session is faster and better for your lawn than zooming around the grass and ultimately needing to re-mow it later. Also, remember that the choke needs to be lower for slower speeds to run properly. 4. Be consistent My yard has never had such a professional look. Chris Wedel/CNET Mowing randomly across your lawn can take up more time and lead to an uneven cut. Follow a pattern instead, using this technique: Start on the edge of your lawn with the discharge chute pointing toward your lawn Mow around the perimeter of your lawn When you get to your starting point, make a U-turn so the discharge chute is facing the strip you just cut Keep mowing around the perimeter, making sure the discharge chute is pointed toward where you just mowed. In the end, your lawn will end up with a nice pattern and the discharge chute won't clog.

Prep your mower for the next round Regular maintenance on your mower is important to ensure it is reliable and does a great job each and every time you take it out. Spending a little time after you finish mowing will keep your mower in tip-top shape and lasting longer. Start by turning the mower over and rinsing the blades and discharge chute with a garden hose before putting it away. This will prevent grass from building up, drying out, and being much harder to remove. If the air filter on your push mower looks dirty, give it a good wash with some mild dish soap and rinse it with the garden hose. Set the filter aside to dry so you can put it on right before mowing next time. One of the best time savers is keeping your lawn mower blade sharp. A dull blade will require you to go over the same patch of lawn more than once to cut any raggedy bits left behind. A sharp blade allows you to zip around your lawn just once and still get great results. Most mower repair shops will sharpen the blades for a small fee, or you can do it yourself with these tips. FAQs to help you get the best-looking lawn What order should I mow my lawn? It's best to start mowing around the edges of your lawn, with the grass clippings going into your uncut grass. After cutting around the entire perimeter of your yard, turn back around and mow in the opposite direction, with the grass chute pointing towards the perimeter grass you already cut. Continue this mowing direction until complete. Want to make watering your lawn easier? Here's CNET's guide to making your own automated lawn watering system.

Flooding and rock slides close heavily damaged I-40 section in Smoky Mountains
HARTFORD, Tenn. -- Heavy rain, flooding and a rock slide have again closed a section of the major cross country highway Interstate 40 along its narrow corridor through the Great Smoky Mountains. The slide and flood happened Wednesday afternoon around mile marker 450 in Tennessee, just to the west of the state line with North Carolina, the Tennessee Department of Transportation said on social media. Crews continued to work Thursday to get the water and rock off the highway and had not released when they think the road could be reopened, the DOT said. The flooded section is part of 12 miles (19 kilometers) of I-40 in North Carolina and Tennessee that was washed away or heavily damaged by flooding that roared through the Pigeon River gorge during Hurricane Helene in late September. Crews repaired and shored up enough of the old highway to open one narrow lane in each direction in March. The lanes are separated by a curb several inches high that had to be removed to let vehicles stuck by the flooding and rockslide to turn around and go the other way. About 2.5 to 3.5 inches (63 mm to 89 mm) of rain fell in the area over about three hours, according to the National Weather Service. The permanent fix to stabilize what's left of the road will involve driving long steel rods into bedrock below the road, filling them with grout and spraying concrete on the cliff face to hold them in place. It will take years. I-40 runs from Wilmington. North Carolina to Barstow, California, and any detour around the Great Smoky Mountain section is dozens of miles. Trucks have gotten stuck on twisty narrow mountain roads and are banned on another major highway through the area U.S. 441 through Great Smoky Mountains National Park.

EDF May Curb French Nuclear Output From June 25 Due to Heat Wave
Electricite de France SA said a heat wave that's spreading across the country may force it to curb nuclear output from June 25 due to the rising temperature of the Rhone river that's used for cooling some of its reactors. Due to the high temperature of the Rhone, production restrictions are likely to affect EDF's nuclear output from June 25, particularly the Bugey power station, the state-owned utility said in a regulatory filing Thursday. The forecast will be reviewed on June 24.
