Currently in Boston — September 12, 2023: Unsettled weather days continue

The weather, currently.

Scattered showers and even the rumble of thunder will continue through the first part of the night. Some of these could contain heavy downpours and create some temporary street flooding. Temperatures will stay in the '60s overnight. During tomorrow look for a lot of clouds and other than an early morning shower I don't expect any rainfall. Temperatures will be in the '70s. Looking ahead towards Wednesday skies will be cloudy again humidity will go up and there's another chance for showers and thunderstorms especially in the afternoon and evening. Temperatures will be 75 to 80. On Thursday after any morning showers I think skies will start to clear. It will turn a bit drier as well.

The effects of Lee could arrive Saturday depending on how close to the coastline it comes.

What you need to know, currently.

The Kīlauea volcano on the big island of Hawai’i began erupting on Sunday afternoon — its fifth eruption in the past four years.

Kīlauea is one of the most active volcanoes on Earth, so this really isn’t a surprise, but it’s still a literally awesome reminder that we all live on a planet that is continually in motion at all space and time scales.

The Hawaiian islands were formed over the past 50 million years by the same plume of upwelling undersea magma in the middle of the Pacific. The island of Hawai’i is the largest and youngest island of the chain — Kīlauea emerged from under the ocean just 100,000 years ago. In 2018, the volcano’s summit collapsed and released a lava flow up to 500m (1600ft) thick that destroyed hundreds of homes and marked a shift into its current eruptive phase. In contrast, this week’s eruption is extremely minor — but still impressive.

The US Geological Survey has set up a live view of the eruption in Kīlauea’s Halemaʻumaʻu crater:
