Due to strong solar flares the past few days, the Northern Lights still may be visible at times during the evening hours all the way through the weekend. While the weather has certainly cooperated with mainly clear skies, the moon continues to get brighter and brighter, which will hamper some viewing of the Northern Lights through the weekend as well. However, if you're really looking for some great colors to possibly appear, it still may be worthwhile, to head out of the city limits and take a gander northward through the weekend.
Another thing that we have been watching for the past two weeks in particular, is the unusual cooling of the Equatorial Pacific Ocean, commonly referred to as La Nina. If you remember last winter (2010-2011), that was a La Nina year for the world and look at all of the snowfall we had, especially early in the season.
For La Nina to bring the exact same thing again this year, the active storm track will need to remain and set up right across Wisconsin, very similarly to last year. However, La Nina doesn't always settle on the same strom track location. So it's tough to say that even if we are sure we are going to experience La Nina this winter, that yields the same result as last season.
While the pieces are in place for a possible snowier than normal winter, it will be quite some time before we're able to make that prediction with any kind of confidence. The National Weather Service will issue their official "Winter Outlook" in the middle of October, while the Farmer's Alamanac is already out. The Farmer's Almanac calls for Colder than normal conditions, with "average snowfall".
