National Weather Forecast
A stalled-out boundary from the Southern Plains to the Southeast will help spark showers and thunderstorms to end the work week. A frontal boundary moving into the upper Midwest will also bring a storm threat – some of which could be strong.
Meanwhile, record heat can be expected Friday out in the western United States, with over two dozen locations potentially setting record highs.
The heaviest rain will be in the southern United States through Saturday, where some locations could see at least 3” of rain.
Meanwhile, we are closely watching several areas in the Atlantic. First, Danielle has formed west of the Azores and has been quickly strengthening on Thursday. A broad area of low-pressure east of the Leeward Islands has a high potential of becoming a tropical depression over the next few days. And an area of low pressure near the Cabo Verde Islands has a low chance of development.
Record-threatening, long-duration heat wave to roast Western U.S.
More from the Washington Post: “Large parts of the Western United States face a prolonged and extreme heat event that is expected to break scores of records over the next week. California’s Central Valley may be particularly hard hit by this heat wave, which the National Weather Service has warned could threaten monthly records over the holiday weekend. Sacramento could be near 110 degrees on Labor Day. Abnormally hot weather has already swelled over the Pacific Northwest; Seattle and Portland set record highs of 90 and 100 degrees on Tuesday. This heat will intensify, spread over more territory in the West and become entrenched in the coming days — lasting at least a week. Even as the heat wave was only beginning on Wednesday, California ISO, the state’s grid operator, issued a “flex alert” calling for voluntary electricity conservation between 4 and 9 p.m.”
International report on 2021 climate: record-high greenhouse gases, ocean heat, and sea level
More from NOAA’s Climate.gov: “Greenhouse gas concentrations, global sea levels and ocean heat content reached record highs in 2021, according to the 32nd annual State of the Climate report. The international annual review of the world’s climate, led by scientists from NOAA’s National Centers for Environmental Information and published by the Bulletin of the American Meteorological Society (AMS), is based on contributions from more than 530 scientists in over 60 countries. It provides the most comprehensive update on Earth’s climate indicators, notable weather events and other data collected by environmental monitoring stations and instruments located on land, water, ice and in space.”
NYC may ban e-bikes in public housing following a spate of fires
More from Canary Media: “Delivery workers represent a significant share of the micromobility movement that’s taking hold worldwide as cities work to curb tailpipe emissions and reduce reliance on cars. Yet in New York City, this burgeoning group of e-bike users has encountered hurdles, ones that raise complicated questions about who can access electrified transportation and how. Most recently, the New York City Housing Authority (NYCHA) has proposed banning the loosely defined category of “e-bikes” from public-housing apartments, where many delivery workers live. The proposal, announced in July, is meant to address a serious problem: the rising number of building fires linked to lithium-ion batteries. In the latest incident, in early August, a 5-year-old girl and a 36-year-old woman died after the battery of an electric moped — also referred to as scooters — exploded inside an apartment in Harlem.”
