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.
Travel hazards, delays and disruptions associated with rain, ice and snow will continue over the Central states through the balance of the Thanksgiving weekend.

The current reprieve from heavy rain across southern India will not last long with the threat for flooding downpours set to return for the final days of November.
Wet weather with areas of ice and snow will stretch from Texas to Michigan and could impact shoppers and slow travel during Black Friday.
Several days of heavy rain will bring the potential to cause flooding from the southern Plains to the middle Mississippi Valley into early next week.

Famous "Portland" storm formed off Cape Cod with loss of 200 lives. Many others were lost to the raging sea in 50 small vessels. A total of 27 inches of snow in New London, CT; 15 inches at Waterbury, CT. Peak wind was 72 mph in Boston. Boston received more than a foot of snow.
Second heavy snowfall in three days hits the region with 12 inches on the ground in NJ; 14 inches in NY; greatest November snow in New England since 1898.
