What are the odds that viewers will be able to see the the partial eclipse of August 21, 2017 in the Twin Cities?

As the event draws near, follow the National Weather Service Forecast.

In the Twin Cities, 83% of the sun will be covered by the moon at 1:06pm CDT August 21, 2017. Looking at recent 1 PM observations in the Twin Cities since the year 2000, skies were mostly sunny (3/8 cloud cover or less) seven of the past 17 years, partly sunny (3/8 to 5/8 cloud cover) five times, and cloudy (7/8 cloud cover or greater) five times. Temperatures have ranged from 65 degrees in 2004 to 84 degrees in 2013. It can occasionally be quite windy with a sustained wind of 17mph with gusts to 24 mph in 2008.

And what should we expect from the August 21st, 2017 eclipse? We should see a noticeable loss of daylight, even if it's cloudy, because up to 83% of the available sunlight will be blocked by the moon. Partial eclipses of the past have produced dusk-like sunlight levels, even during the middle of the day. The 2017 eclipse will occur at a time when temperatures normally would be climbing by a degree or two per hour, but we should expect temperatures to lose ground for an hour or so, possibly affecting our ability to reach what would have been the high temperature otherwise. Although we will not be in the "path of totality," observant Minnesotans will have no problem recognizing the partial eclipse.

The National Weather Service has more Eclipse Information.
