I’ve seen the northern lights (aurora borealis) twice in my life. The most vivid northern lights that I witnessed were near Park Rapids, Minn., on a summer lake trip a few years ago.

We’ll have a chance to see northern lights Thursday night as a coronal mass ejection from the sun interacts with the Earth’s magnetic field.

Patchy clouds are expected over parts of Minnesota this evening, but those clouds are expected to break up a bit overnight into Friday.

The potential viewing area of the aurora includes most of Minnesota and Wisconsin, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center:

The red-shaded area that covers Canada and far northern Minnesota indicates where (weather permitting) the chances of seeing the northern lights are highest Thursday night. The thin red line in southern Iowa shows where aurora may be visible on the northern horizon.

Northern lights often surprise us. Sometimes they are more vivid and extensive than expected and sometimes they are limited in coverage and less vivid than expected.

If you go to NOAA’s Space Weather Prediction site, be aware that they use Universal Time, which is 6 hours ahead of Central Standard Time. Dec. 1 begins at 6 p.m. CST on that site.

The MPR News staff compiled some tips on northern lights viewing and picture-taking.

Back to the 30s

The Thursday high temperature at Minneapolis-St. Paul International Airport was 42 degrees, which is well above the average Nov. 30 Twin Cities high temp of 35 degrees.

The metro area will share highs in the 30s with much of Minnesota and western Wisconsin on Friday:

Saturday highs will be mainly in the 30s:

Highs in the 30s linger in most areas on Sunday, with some lower 40s to the southwest:

Twin Cities metro area high temps are projected to reach the upper 30s on Monday, then around 40 degrees Tuesday followed by lower 40s Wednesday and mid-40s next Thursday.

We may have more mild days than cool days in December, according to the temperature outlook from the National Weather Service Climate Prediction Center:

Weekend flake chances mainly to the southeast

A low-pressure system passes to our southeast this weekend. Some accumulating snow is expected in Iowa and southern Wisconsin late Saturday into Sunday.

Far southeastern Minnesota could see some light snow late Saturday into early Sunday. We can’t rule out a few few flurries Saturday night or early Sunday in the Twin Cities metro area.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from noon on Saturday to 6 p.m. Sunday:
