National Weather Forecast

On Monday, we are watching showers and storms across the eastern and southern United States, as well as in the Rockies, Upper Midwest and Pacific Northwest. However, all eyes will be on the Yucatan Channel where Idalia will be sitting before it heads toward the Southeastern United States in the early Wednesday timeframe.

The heaviest rain through the first part of the week will be in the Southeastern United States, where rainfall amounts of 3”+ will be possible.

Here is the expected track for Idalia. The system is expected to strengthen into a hurricane early in the week, and could rapidly strengthen before landfall as it moves across the Gulf of Mexico. We will have to watch this system closely over the next several days for its potential impact in the Southeastern U.S., including heavy rain, storm surge, and strong winds.


Record-Low Ice Levels in Antarctica Killed Thousands of Penguin Chicks, Study Says

More from Gizmodo: “Thousands of penguin chicks in four emperor penguin colonies likely died after Antarctic ice broke up earlier than usual last year, creating a “catastrophic breeding failure.” In a study published this week in Communications Earth & Environment, researchers from the British Antarctic Survey outlined the very high probability that most chicks from four out of the five known emperor penguin colonies died in 2022. Researchers monitored five colonies that range from about 630 pairs to over 3,000 penguin pairs. They counted the birds in the colony using satellite imagery from 2018 to 2022. Through those images, they noticed that significant sea ice loss at the central and eastern Bellingshausen Sea occurred before the penguin chicks would have developed their waterproof feathers.

New modeling method helps to understand extreme heat waves

More from the Cornell Chronicle: “To prepare for extreme heat waves around the world – particularly in places known for cool summers – climate-simulation models that include a new computing concept may save tens of thousands of lives. The concept, called “ensemble boosting,” uses computationally efficient modeling to simulate a large set of extreme but plausible heat waves, all while avoiding hundreds of hours of expensive calculations on large computers. The study on the new modeling method, led by scientists at ETH Zurich, Switzerland and Cornell, was published Aug. 22 in Nature Communications. “As a society, we don’t always need to learn from our mistakes,” said co-author Flavio Lehner, assistant professor of Earth and atmospheric sciences in the College of Agriculture and Life Sciences. “We can learn from our forecasts and predictions.”


More from The Cool Down: “A neighborhood in a city outside of Boston is making headlines for being one of the first to make a comprehensive transition to geothermal energy. Local gas utility Eversource has started connecting more than 40 buildings in Framingham, Massachusetts — including low-income apartments, homes, small businesses, and a fire station — into a network with zero-emission, ground-source heat pumps, Fast Company reported. This makes the utility the first in the United States to undergo such a project on a neighborhood scale. The pilot project resulted from the Home Energy Efficiency Team, a nonprofit that initially worked with Eversource to decrease methane emissions from gas leaks. The focus gradually shifted to solutions providing affordable heating for communities — without releasing any planet-warming pollution.
