Friday and Saturday were beautiful, with plenty of sunshine and comfortable temps. Our Sunday will be fairly nice too. A few spots in Minnesota and western Wisconsin could see a brief shower late Sunday afternoon or early Sunday evening.

You can hear updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News network, and you can see updated weather info on the MPR News live weather blog.

Lunar eclipse Sunday evening

There will be a total lunar eclipse this Sunday evening. That means that the full moon will pass through the earth’s shadow.

Times on the eclipse image above are in Universal time; subtract 5 hours to get Central Daylight Time. For example: 03:29 a.m. Monday Universal time is 10:29 p.m. Sunday Central Daylight Time.

According to NASA, this is why the moon will look coppery-red during the total eclipse phase:

The Moon moves into the inner part of Earth’s shadow, or the umbra. Some of the sunlight passing through Earth’s atmosphere reaches the Moon’s surface, lighting it dimly. Colors with shorter wavelengths ― the blues and violets ― scatter more easily than colors with longer wavelengths, like red and orange. Because these longer wavelengths make it through Earth’s atmosphere, and the shorter wavelengths have scattered away, the Moon appears orangish or reddish during a lunar eclipse. The more dust or clouds in Earth’s atmosphere during the eclipse, the redder the Moon appears.

According to timeanddate.com the timing of the lunar eclipse looks like this in Minneapolis:

9:27 p.m. partial eclipse begins.

10:29 p.m. total eclipse begins (moon is coppery red)

11:53 p.m. total eclipse ends.

12:55 a.m. partial eclipse ends.

Times will be slightly different in other parts of Minnesota and western Wisconsin. The linked location also has an excellent animation of how the eclipse will progress.

NASA also has several excellent eclipse animations. You can select Central Daylight Time or just subtract 5 hours from each image at the NASA site that uses Universal Time.

If you miss tonight’s lunar eclipse, when is the next one?

According to timeanddate.com, the next total lunar eclipse visible in the Twin Cities is Nov. 7 into Nov. 8. After that date, the next total lunar eclipse visible here is in March of 2025.

Flooding update

Flood warnings (shaded green) continue in portions of northeastern Minnesota and a small part of north-central Minnesota:

Snowmelt plus generous rains the past couple of weeks are causing very high river and stream levels in some areas and lake levels are also high in many locations.  According to the NWS, the Pigeon River near Grand Portage has exceeded its record water level:
