The Northern Lights: Will We Be Able to See Them Tonight? #Aurora

The Northern Lights are sometimes visible around here. Not too often but SOMETIMES.
Because of some recent geomagnetic storm action, there's a chance that tonight (July 13th)  we might be able to see the Aurora Borealis/ Northern Lights. Although NPR is now saying the Northern Lights forecast has changed.
Notes:
- best time to look for the Northern Lights is 10p to 2a.
- This site gives the NLI (Northern Light Index... that's not what they call it but...)
- Thanks to Wanita who suggested that we try these apps...
