National Weather Forecast

A new system will impact the Northwestern United States on Saturday, bringing the region more rain and snow. A system working east will bring some snow and rain concerns to the Upper Midwest. Meanwhile, just a few other scattered areas of precipitation are expected in the eastern U.S.

Heavy rainfall will continue to impact the Northwest through the weekend, with three-day totals of over 3” for some – especially along the coast and up into the Cascades where most of the precipitation will fall as rain.

A few inches of snow can’t be ruled out, though, in the Cascades and Northern Rockies.


Study links changes in global water cycle to higher temperatures

More from Washington University in St. Louis: “A study from the Past Global Changes (PAGES) Iso2k project team, led by Bronwen Konecky at Washington University in St. Louis, takes an important step toward reconstructing a global history of water over the past 2,000 years. Using geologic and biologic evidence preserved in natural archives — including 759 different paleoclimate records from globally distributed corals, trees, ice, cave formations and sediments — the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.

Full steam ahead for electric freight trains

More from Canary Media: “Electricity is taking over the transportation sector, with batteries replacing fossil-fuel engines in a growing number of passenger cars, big-rig trucks, school buses, delivery vans, speedboats and ferries. Yet one category in particular is only just starting to get on board with battery power: freight trains. In the United States, tens of thousands of locomotives rumble down railroads every year, pulling cars that collectively carry around 20 billion tons of cargo. All of these powerful engines run on diesel fuel — and, as a result, generate both planet-warming emissions and harmful air pollution that afflicts communities surrounding rail yards and railways. This week, Wabtec Corp., a rail technology company, took what it says is a ​“major step” toward electrifying this heavy-duty industry.

Without Warning: A Lack of Weather Stations Is Costing African Lives

More from Yale Environment 360: “In early May, heavy rainfall led to severe flooding and hundreds of landslides around Lake Kivu, on the border between Rwanda and the Democratic Republic of the Congo (DRC), killing at least 600 people. The floods, which caught many as they slept, also displaced thousands of people, destroyed water infrastructure, and damaged productive farm fields. Floods are one of the deadliest natural disasters worldwide, but deaths linked with flooding aren’t distributed evenly. They most often occur in places that lack weather data and warning systems — and most of those places are in the Global South. While the rainfall around Lake Kivu this past spring was extremely heavy, it was the lack of warming that turned this weather event into a humanitarian disaster. To avoid similar disasters in the future, countries in Africa and other parts of the world need funding for early warning systems, weather stations, and climate modeling. Such investments will benefit people the world over.
