Most of Alaska is now covered in clouds, and snow is predicted. All we can do is hope for a clearing each night.
The forecast for tonight is still looking great! I have read in the news media that the storm will begin on Monday night. Do not be fooled. The forecast is for TONIGHT, Sunday night, and may last 3 nights. The aurora storm is due to a high speed solar wind stream from a coronal hole (CH HSS). Last time we saw this coronal hole was a month ago, during the big Oct 6 show we had, where we saw streaks of purple with the naked eye.
Northern and mid latitude states, all of Canada, and all of Alaska be on alert tonight. If you cannot stay up to wait, check again in the morning when it is still dark. There is a possibility that it may not arrive tonight, but it CAN. Also be ready for Monday night!
