Winter Storm Xerxes became the latest nuisance storm to pound the Northern Plains, dealing yet another snowy blow to the Dakotas and Minnesota on Sunday.

"I'm not sure which is more cruel -- the blizzard in Bismarck, which has had a few tastes of 60-degree weather this spring, or the snowstorm ahead for Grand Forks, which hasn't gotten above 40 degrees even once so far in 2013," said weather.com meteorologist Nick Wiltgen.

CME IMPACT: A coronal mass ejection (CME) swept past Earth on April 13th around 22:55 UT. The impact rattled Earth's magnetic field and induced electrical currents in the ground around the Arctic Circle. Rob Stammes recorded the effects of the impact from a geophysical monitoring station at the Polar Light Center in Lofoten, Norway:

 

"On my instruments there was a clear sugnature of the incoming coronal mass ejection," says Stammes. "The impact was not as strong as expected, but there were nice variations on my magnetometer and ground current instruments. There were also Northern Lights."

A look at a powerful M6.5 class flare, the strongest of 2013 at the time, at 3:16 EDT on April 11, 2013. This image shows a combination of light in wavelengths of 131 and 171 Angstroms.

The most powerful solar flare of the year erupted from the sun Thursday, sparking a temporary radio blackout on Earth, NASA officials say.

The solar flare occurred at 3:16 a.m. EDT and registered as a M6.5-class sun storm, a relatively mid-level flare on the scale of solar tempests. It coincided with an eruption of super-hot solar plasma known as a coronal mass ejection.
