The weather, currently.

Wee bit of snow possible for Friday

Colder air will slowly drain into the region over the next 24 hours. At the same time a little bit of moisture will ride from the southwest towards the northeast Friday afternoon and early evening. Since temperatures will be marginal some of this precipitation will fall as snow. It looks like if there's going to be a coding to an inch or two it will be north and west of Route 128 and Route 495. Roads should remain on the wetter side instead of becoming snow covered. The trickiest travel will occur along the Massachusetts border and into Northern New England. Skies will clear for the weekend with temperatures in the lower 40s on Saturday and reaching the mid to upper 30s on Sunday both with at least partial sunshine.

The US has a new emissions standard for heavy-duty trucks for the first time in over 20 years, the Environmental Protection Agency announced Tuesday.

This stricter pollution rule is part of the agency’s Clean Trucks Plan and is the first time pollution standards for buses and heavy duty trucks have been updated in more than two decades, according to reporting by Grist.

The standard will be enforced when 2027 vehicles are available to buy.

This is significant because heavy-duty vehicles are one of the major emitters of nitrogen oxide, which, in large concentrations can exacerbate heart disease, asthma, and other respiratory diseases.

The updated standard is particularly good news for communities that bare the brunt of vehicle pollution — such as low-income people of color — who are more likely to live and work near factories, major highways, and other places where vehicles cause the most pollution due to racist zoning laws and redlining.

The agency estimates that heavy-duty vehicle nitrogen dioxide emissions will decrease by 48 percent by 2045, because of the rule. The new standard is expected to prevent up to 2,9000 deaths by 2045.
