National Weather Forecast

Showers and thunderstorms will be possible across the eastern United States on Saturday with a cold front trying to move in and an area of low pressure off the coast. Showers and storms will also be possible in parts of the western United States, with some snow at the higher elevations of the Colorado Rockies. Smoke from wildfires in Canada could make it to the surface from Montana to the Front Range and even into parts of Texas. Numerous record highs are expected in the Northwest.

Through the weekend, up to around 3” of rain could fall across portions of the Southern Plains and along the East Coast.

Wet weather is expected for the PGA Championship on Saturday in Pittsford, NY. The best chance of showers and possibly a thunderstorm will be in the morning and midday hours, with drier weather likely moving in for the afternoon to get some golf in. The good news is that Sunday looks nice and sunny.

Hot summer ahead for much of the U.S.

More from Axios: “The climate outlook for June through August shows a broad swath of the Lower 48 states and Alaska are likely to see a hotter than average summer. Why it matters: Prevailing weather conditions during the summer lead to drought or destructive wildfires. Climate outlooks like this one can help power companies plan for higher electricity demand during heat waves. Context: Because of human-caused climate change, average summer temperatures are on the rise across much of the U.S. For example, this means a hotter than average summer in Phoenix now is far warmer than a hotter than average summer in a typical year during the 1970s.”

Warming and Drying Climate Puts Many of the World’s Biggest Lakes in Peril

More from Inside Climate News: “Water storage in many of the world’s biggest lakes has declined sharply in the last 30 years, according to a new study, with a cumulative drop of about 21.5 gigatons per year, an amount equal to the annual water consumption of the United States. The loss of water in natural lakes can “largely be attributed to climate warming,” a team of scientists said as they published research today in Science that analyzed satellite data from 1,980 lakes and reservoirs between 1992 and 2020. When they combined the satellite images with climate data and hydrological models, they found “significant storage declines” in more than half of the bodies of water. The combination of information from different sources also enabled the scientists to determine if the declines are related to climate factors, like increased evaporation and reduced river flows, or other impacts, including water diversions for agriculture or cities. A quarter of the world’s population lives in basins where lakes are drying up, they warned.”

El Niño could cost the global economy $3 trillion

More from Grist: “Forecasters are predicting the formation of an El Niño later this summer, a natural weather phenomenon that fuels above-average global heat and more intense natural disasters in parts of the world. A new study reveals that there are also strong economic repercussions to an El Niño — the pattern threatens to slow the global economy by as much as $3 trillion. The planet’s weather over the past three years has been dominated by El Niño’s opposite extreme, La Niña, which has had a cooling effect on the globe despite the warming effects of climate change. The shift to El Niño, which is characterized by warmer-than-normal sea surface temperatures in the eastern Pacific Ocean, in conjunction with accelerating climate change, means a wide array of exacerbated hazards may be coming down the pike. Those impacts come with a surprisingly steep price tag, according to the study, which was published in Science on Thursday. By the end of the century, El Niño cycles may spur a whopping $84 trillion in economic losses.”
