National Weather Forecast

A frontal boundary and wind flow off the Great Lakes will lead to continued lake-effect snow across the region. Some rain is expected with a frontal boundary across much of Florida and the eastern Gulf Coast. Rain chances continue across parts of Texas with some morning mixed precipitation as well. Meanwhile, we’ll watch the next system start to approach the Pacific Northwest.

Heavy lake effect snow is continuing this weekend in the Great Lakes, with some of the heaviest additional snow expected off of Lake Ontario where a couple more feet will be possible. Some areas of the southern United States could pick up an inch or two of rain.


Air pollution high at US public schools with kids from marginalized groups

More from the AGU: “Race- and ethnicity-based discrepancies in exposure to air pollution, especially regarding proximity to roadways and industrial zones, are well-established. A new study reports the first nationwide patterns in atmospheric fine particulate pollution and nitrogen dioxide exposure at U.S. public schools. On both national and local scales, schools with more students of color and students who receive free or reduced-price lunches, a proxy for poverty, are located in areas with higher concentrations of the pollutants, the study found. The study, led by members of NASA’s Health and Air Quality Applied Science team, was published in GeoHealth, AGU’s journal for research that investigates the intersection of human and planetary health for a sustainable future.

Sea level rise to dramatically speed up erosion of rock coastlines by 2100

More from Imperial College London: “Rock coasts, which make up over half the world’s coastlines, could retreat more rapidly in the future due to accelerating sea level rise. This is according to new Imperial College London research that modelled likely future cliff retreat rates of two rock coasts in the UK. The forecasts are based on predictions of sea level rise for various greenhouse gas emissions and climate change scenarios. The study found that rock coasts, traditionally thought of as stable compared to sandy coasts and soft cliffs, are likely to retreat at a rate not seen for 3,000-5,000 years.

COP27: Without Greta, activists make waves at climate summit

More from BBC: “Young people are a more powerful force than ever in the UN climate summit, the UN’s youngest climate advisor tells BBC News in Egypt. ”Young people are definitely shaping outcomes here at COP27,” Sophia Kianni says. Swedish campaigner Greta Thunberg has skipped the Sharm el-Sheikh meeting, calling it a forum for “greenwashing”. But young people from countries at high risk from climate change say they are “calling it out” from inside. In an address on Tuesday, climate activist Vanessa Nakate from Uganda will tell governments to wash their “oil-stained” hands.
