A series of solar flares this week may yield additional episodes of the aurora borealis (Northern Lights).
Areal coverage of the displays produced by each coronal mass ejection are difficult to gauge ahead of time. The Northern Lights were visible over part of the Great Lakes region Wednesday night.
The best chance for viewing the show tonight, if the Earth's magnetosphere cooperates, will be in the northern Plains, part of the Midwest and much of the West.
There will be a nearly full moon tonight, which could detract from viewing the show somewhat. However, the display was still impressive last night, despite the full moon.
Experts at Space Weather.com state that not only do the magnetic storms unleashed by the flares cause the aurora borealis, but they can be somewhat disruptive.
The expanse of the Northern Lights and disruptions depend on whether or not the flare directly strikes the Earth versus a glancing blow, as well as the strength of the coronal mass ejection itself.
In the extreme case, there can be brief disruptions to radio and gps signals.
Space Weather indicates that a strong magnetic storm can cause satellite onboard computer systems to reboot.
As a precaution, some commercial flights will reroute their trips from polar regions.
This weekend will feature snow showers and icy conditions for Minneapolis.
While the official start to winter is still days away, the cold, icy and snowy weather across most of the United States would indicate otherwise.
Another winter storm is on the way for the mid-Mississippi Valley, but areas hit hard by the recent ice storm will be spared the worst.
The holidays are a very busy time for firefighters and emergency medical personnel who deal with seasonal-related fires, falls and other emergencies.
Heavy snow and travel disruptions will spread from a large part of the Midwest Friday night to the Northeast during Saturday.
Two storms will bring high winds to the United Kingdom and Ireland this weekend.
