Simulated Radar From 1AM Sunday to 7AM Tuesday
Here's the simulated radar from 1AM Sunday to 7AM Monday. After a mostly dry and sunny Saturday, scattered showers and a few rumbles of thunder will scoot through the region overnight Saturday into AM Sunday. There might be a few lingering showers in the morning Sunday, but we should be able to dry out a bit during the middle part of the day before a few more isolated showers/storms develop late in the day.
Rainfall Potential Through AM Monday
The rainfall potential through AM Tuesday shows around 0.10" to 0.25" of rain across parts of the state. There could be isolated higher amounts with any thunderstorms that develop through the rest of the holiday weekend.
Sunday Weather Outlook
The weather outlook for the Twin Cities on Sunday, which shows a few showers still possible during the morning hours. It appears that we will have some drier weather around midday and into the early afternoon, but there could be another round of isolated showers/storms that pop up later in the afternoon. Temps will only warm into the mid 60s, which will be nearly -5F to -10F below average.
Minneapolis Meteograms
The meteograms for Minneapolis on Sunday shows temps warming from the lower 50s early in the morning to the mid 60s by mid/late afternoon. It'll be a somewhat soggy start with scattered showers in place in the morning. It looks like the midday hours will be drier, but there could be a be pop up showers/storms later in the day.

Spring freeze injury to corn in the northern half of Minnesota: What to expect
"Air temperatures dropped below freezing during the early morning hours on May 28 in portions of the northern half of Minnesota, resulting in freeze injury to corn in some fields. Most of the damaged corn was at the two to three leaf collar (V2 to V3) stages. Symptoms of freeze injury to corn initially appear as discolored water-soaked leaves, which later dry and turn brown. The growing point on young corn plants at the V2 to V3 stages is about 0.75 inches below the soil surface, and it will remain below the soil until the five leaf collar (V5) stage. Therefore, freezing air temperatures prior to the V5 stage typically do not kill corn unless prolonged cold temperatures freeze the upper part of the soil where the growing point is located."

Have a Plan B Today - Hot Front Next Weekend
By Paul Douglas
"So Paul, riddle me this. Why does it rain more on holiday weekends?" Actually it doesn't. But perception trumps reality. More of us spend time outdoors on holiday weekends, at the mercy of Mother Nature. We are more attuned to the state of the sky, more "weather sensitive". Rain impacts our plans - we remember it more than puddles on a weekday.
Exhibit A: today. According to Dr. Mark Seeley, in spite of Thursday's drenching rains, 70 out of 87 Minnesota counties are drier than average; 16 counties are still in moderate drought. The timing is a bit suspect, but yes, we still need rain. Today will be the coolest, cloudiest day of the holiday with a few hours of showers, especially this morning. A northwest breeze kicks in on Memorial Day with more sunshine and 70s, but watch for a late-day instability thunderstorm.
A sweaty ridge of high pressure pumps hot air into Minnesota later this week with 90 degrees next weekend.
We'll go from complaining about frost to whining about the heat in less than 1week.

What's in the Night Sky?
"On the mornings of May 30 to June 2, 2021, watch for the waning moon to sweep by two bright planets – two outer solar system gas giants – golden Saturn and bright Jupiter. Unless you're a night owl, you probably won't see the moon, Saturn and Jupiter rising into your sky before your bedtime. But they'll be glorious at dawn. Look for the threesome – the moon, Saturn and Jupiter – along the path that the sun and moon travel across your sky. They'll be visible just before dawn, and (in the case of Jupiter and the moon), as dawn is beginning to break. It's pretty easy to distinguish Jupiter from Saturn, because Jupiter is much brighter. Although Saturn shines as brilliantly as a 1st-magnitude star – or one of the brightest stars in our sky – Saturn pales next to Jupiter, the largest planet in our solar system. Jupiter outshines Saturn by some 16 times. Jupiter ranks as the 4th-brightest celestial body to light up the heavens, after the sun, moon and the planet Venus, respectively. Fortunately, there's no way to mistake Jupiter for Venus, or vice versa, because, in May 2021, Venus is up in the evening sky."
National High Temps Sunday
The weather outlook on Sunday shows cooler than average temperature in place east of the Rockies. Some of the coolest readings will be found in the Northeast including Washington DC to New York, where temps will be nearly -10F to -20F below average. Folks in the Western and Southwestern US will actually be warming up to well above average levels as we head into the late weekend time frame and into early next week.
National High Temps for Memorial Day Monday
Memorial Day Monday will be even warmer in the Southwest and also a little warmer in the Eastern US. Cooler conditions will across the Front Range with another round of showers/storms expected to continue.

"NEW NASA SATELLITE WILL BLAST EARTH WITH FLASHES YOU CAN SEE FROM THE GROUND"
"NASA is launching a bizarre satellite that will allow anyone to trigger a blinding flash of light in space that will be visible from the ground with the naked eye. The toaster-sized CubeSat, named LightCube, will launch sometime between 2022 and 2025, according to a NASA press release. The satellite, which was designed by the startup Vega Space Systems and Arizona State University students, is supposed to be an educational project. But as Forbes contributor Ethan Siegel notes, the invasive on-demand flashes of light could pose a problem for scientists' attempts to study the cosmos. NASA's decision to approve and back the LightCube project comes as a bit of a shock given the astronomy research community's recent and ongoing outcry against light pollution in space caused by the SpaceX Starlink constellation and the multitude of other satellites in the sky. Given those complaints, it's surprising to see NASA support a project that would allow anyone with a HAM radio to create a blinding flash in the sky. The satellite itself uses powerful xenon flash tubes — the same tech used in camera flashes and some medical imaging — to create lights that Siegel warns could interfere with both terrestrial and orbital observatories, potentially causing them to miss any short-lived natural phenomena in space that happens at the same time."
"GPS satellites can provide faster alerts when big earthquakes strike, scientists say"
"A GPS-based system can provide earlier alerts than seismic sensors when devastating earthquakes strike. A global GPS-based earthquake monitoring system can provide timelier and more accurate warnings than traditional seismic networks when powerful earthquakes strike, a new study suggests. It could also reduce frequency of false alerts. In the new study, published this month in the Bulletin of Seismological Society of America, a team of researchers detailed new progress in the development of a global earthquake warning system that measures the displacement of Global Positioning System (GPS) satellite receiver stations when an earthquake deforms the Earth's crust. The system assesses the magnitude of an earthquake within seconds and issues alerts in under two minutes from the first detection of the ground movement. According to lead author Timothy Melbourne, professor of geology at Central Washington University, the GPS-based detection system can provide earlier and more accurate alerts than the traditional seismic sensors distributed in tectonically active regions, which can be overwhelmed with an initial surge of data when seismic waves first emerge."
"The World's Northernmost Town Is Changing Dramatically"
"Mark Sabbatini first noticed the cracks in his apartment's concrete walls in 2014. It had been six years since he moved to Svalbard, a Norwegian archipelago far out in the Barents Sea, about halfway between Norway's northern tip and the North Pole. He was an itinerant American writer drawn by promises of an open, international society—and jazz music. Every winter the community of Longyearbyen, the world's northernmost town at 78 degrees North latitude, holds a jazz festival to liven up the perpetual darkness. Residents, university students, tourists and visiting scientists mingle in music halls, clinking champagne glasses to melodious tones as winds howl through the surrounding mountains. On his first visit Sabbatini had arrived just in time for the festivities. Svalbard, he says, instantly felt like home. "It was like when you look across the room and spot somebody and fall in love." But fissures were now appearing in the relationship. Sabbatini worried the apartment cracks were caused by a leaky roof; it had been raining more than usual. Then he realized the building's concrete foundation was buckling. Fractures slithered up the stairwells and defaced the building's beige exterior. The next year tenants discovered that part of a cooling system underneath the building, meant to help keep the permafrost ground frozen and stable during warm spells, was faltering. "And we were getting a lot of warm spells," Sabbatini says. Suddenly, on a February afternoon in 2016, town officials ordered the occupants to evacuate, afraid the building could collapse. Sabbatini and 29 others had only a few hours to pack and get out."
