April Rain And Snow Showers – National Weather Outlook For April 11, 2021

National Weather Forecast

On Sunday, a system working into the Great Lakes will bring rain chances across the upper Midwest and Great Lakes. An associated cold front and additional low in the Southeast will bring the potential for storms from the Northeast to Florida. A second low dropping into the Northern Plains will bring rain and snow chances from Montana into the upper Midwest.

A couple areas of heavy rain are expected through Monday evening – one across the central/eastern Gulf Coast, and another in the Upper Midwest. In these areas, 1-3” of rain could fall. Several inches of snow will be possible from the Cascades across the Northern Rockies and into the Northern Plains.

‘Average’ Atlantic hurricane season to reflect more storms

More from NOAA: “Beginning with this year’s hurricane season outlooks, NOAA’s Climate Prediction Center (CPC) will use 1991-2020 as the new 30-year period of record. The updated averages for the Atlantic hurricane season have increased with 14 named storms and 7 hurricanes. The average for major hurricanes (Category 3, 4 or 5) remains unchanged at 3. The previous Atlantic storm averages, based on the period from 1981 to 2010, were 12 named storms, 6 hurricanes, and 3 major hurricanes. NOAA is updating the set of statistics used to determine when hurricane seasons are above-, near-, or below-average relative to the climate record. This update process occurs once every decade. “This update allows our meteorologists to make forecasts for the hurricane season with the most relevant climate statistics taken into consideration,” said Michael Farrar, director of NOAA’s National Centers for Environmental Prediction.”

Blizzard and historic April cold hit Alaska, with temperatures 50 degrees below normal

More from the Capital Weather Gang: “Springtime in the Last Frontier doesn’t always mean April showers. Blizzard conditions, wind chills of minus-70, and temperatures more than 40 degrees below zero are gripping the nation’s 49th state, beneath a record-cold air mass in the lower atmosphere. Alaskans have endured abnormally cold weather since February, and the intensity has set records in recent days. Temperatures on Tuesday morning fell to minus-24 degrees in Fairbanks and minus-33 in Bettles, both record lows for the date. Livengood, about 60 miles north-northwest of Fairbanks, plummeted to minus-31. A number of other locales dropped down to minus-25 to minus-30.”

First-Ever Observations From Under Antarctica’s ‘Doomsday Glacier’ Are Bad News

More from Earther: “Researchers have known that the Thwaites Glacier is in trouble due to encroaching warm waters, but they’d never actually analyzed data from beneath the glacier’s float ice shelf—until now. A new study published in Science Advances on Friday presents the first-ever direct observations of what’s going under the infamous ice shelf, including the temperature and salinity of the water that’s flowing under it as well as the strength of the current. What they found is pretty troubling. The authors explain that the supply of warm water to the glacier’s base is larger than scientists previously believed, which means it’s even more unstable than we thought. Given that it’s often called the “doomsday glacier,” that’s particularly ominous.”
