National Weather Forecast

On Saturday, the last of a system that has been impacting parts of the Northeast will start to move away, gradually bringing an end to rain and snow showers that stretch from New England down the Appalachian Mountains. A clipper moving out of Canada into the Great Lakes will bring the Upper Midwest and western Great Lakes some snowfall. A system continues to impact the West Coast with rain and higher-elevation snow.

The heaviest rain through the weekend will fall in parts of northern and coastal California, where tallies over 3” will be possible.

The heaviest snow through the end of the year will fall at some of the higher elevations of the Sierra, where a foot to a foot and a half will be possible.

Meanwhile, for the Ball Drop in Times Square Sunday evening, quiet conditions are expected with temperatures hovering around 40F.

Earth Was Due for Another Year of Record Warmth. But This Warm?

More from the New York Times: “Earth is finishing up its warmest year in the past 174 years, and very likely the past 125,000. Unyielding heat waves broiled Phoenix and Argentina. Wildfires raged across Canada. Flooding in Libya killed thousands. Wintertime ice cover in the dark seas around Antarctica was at unprecedented lows. This year’s global temperatures did not just beat prior records. They left them in the dust. From June through November, the mercury spent month after month soaring off the charts. December’s temperatures have largely remained above normal: Much of the Northeastern United States is expecting springlike conditions this week.

40% of US electricity is now emissions-free

More from ArsTechnica: “Just before the holiday break, the US Energy Information Agency released data on the country’s electrical generation. Because of delays in reporting, the monthly data runs through October, so it doesn’t provide a complete picture of the changes we’ve seen in 2023. But some of the trends now seem locked in for the year: wind and solar are likely to be in a dead heat with coal, and all carbon-emissions-free sources combined will account for roughly 40 percent of US electricity production.

Amazon plans to make its own hydrogen to power vehicles

More from The Verge: “Amazon is making plans to produce hydrogen fuel at its fulfillment centers. The retail behemoth partnered with hydrogen company Plug Power to install the first electrolyzer — equipment that can split water molecules to produce hydrogen — at a fulfillment center in Aurora, Colorado. The electrolyzer will make fuel for around 225 fork lift trucks at the site, although Plug says it has the capacity to fuel up to 400 hydrogen fuel cell-powered forklifts. This is the first time Amazon has tried to make its own hydrogen on site, and it’s not likely to be the last.
