Heavy Rain In The Central U.S. – Weather Outlook For March 22, 2021

National Weather Forecast

On Monday, a system working through the central United States will bring the potential of storms to the Southern Plains, with showers and even a mix of rain/snow as you head into the upper Midwest/western Great Lakes. Another system in the Pacific Northwest will bring rain and snow to the region. Most of the eastern United States should be dry, with just some occasional showers in eastern North Carolina and in portions of Florida.

Through Tuesday evening, the heaviest rain will fall across portions of the central United States, where up to 3” of rain could fall. 1-3 feet of snow will be possible in some of the mountain ranges out west.

Long-Dormant Volcano in Iceland Awakens in Fiery Eruption

More from Earther: “A long-dormant volcano erupted on Iceland’s Reykjanes Peninsula on Friday, shooting a fountain of lava that lit the night sky roughly 19 miles (30 kilometers) southwest of the nation’s capital, the Icelandic Meteorological Office reported Friday. The eruption, estimated to be the peninsula’s first in almost 800 years, follows weeks of increased seismic activity in the region. “The eruption is considered small at this stage and the eruptive fissure is app. 500 m [546 yards] long. The magma area is app. 1km2. [0.4 square miles],” the IMO said in a tweet. “Lava fountains are small.””

Fossils in a Forgotten Ice Core Rewrite Greenland’s Icy Past

More from WIRED: “Andrew Christ remembers the day he became part of “this 60-year, weird, wild Cold War story.” It was 2019, and the University of Vermont researcher was just four days away from defending his dissertation. He was beyond stressed and had better things to do than help examine an ice core sample drilled decades earlier. The core was subglacial sediment and rock, taken from below a mile of ice in 1966 at Camp Century, an American research base in Greenland that had served as cover for a secret—and failed—military project. Since being pulled from beneath the ice sheet, the sample had been separated from the rest of the core, had criss-crossed the Atlantic, was lost, and then rediscovered. But it had never been analyzed.”

Summers could last for half the year by 2100

More from The Guardian: “Our summers are already about 20% longer than they used to be, and if the climate crisis continues unabated then northern hemisphere summers could cover nearly half of the year by 2100, making them more than twice as long as they were in the 1950s. And unlike their counterparts of the 1950s, future summers will be more extreme, with heatwaves and wildfires more likely. Researchers used historical climate data to measure how much the seasons have changed already. They defined summer as the onset of temperatures in the hottest 25% for that time period and winter as the onset of the coldest 25% of temperatures. Their results, published in Geophysical Research Letters, show that the average northern hemisphere summer has grown from 78 to 95 days between 1952 and 2011, while winter has shrunk from 76 to 73 days. Spring and autumn have contracted too.”
