Looks like the cold front is finally coming to Minneapolis and St Paul, but hopefully you enjoyed a summer like day! You can see the cold front on radar - the line there is a wind shift. Expect a slight storm chance soon, and also around 5pm or 6pm.

According to Henn Cty Sheriff there they had followed a stolen car with youth smashing windows by helicopter and stopped them here. According to bystanders there was an ICE vehicle with some youth inside. I saw none of this myself so interpret what you will. Thanks to whistles for drawing me in.

Something happening with county and feds on Nicollet between 26th and 27th.

The closest I’ve come to death in Minneapolis was a right-on-red driver turning into me on the two-way at Stinson & East Hennepin. My bike hit her front quarter-panel and I barrel-rolled over her windshield. I was lucky with only a concussion. This directive can’t be acted upon fast enough.

Today the Minneapolis City Council's Climate & Infrastructure Committee will be discussing the city's 2-way bikeways and conflicts with right turning vehicles at signalized intersections. Most of these intersections don't have signage prohibiting a right turn through a red light.

Thanks to @mprnews.org Kirsti Marohn for this article on our newly-opened Avivo Village Central Minnesota! They really captured what we're looking for in the new space as people move in ahead of the winter. Also, a huge thank you to JD for sharing his story! www.mprnews.org/story/2026/1...

mprnews.orgNew Avivo shelter in St. Cloud offers privacy, security to people experiencing homelessnessPeople sometimes avoid going to homeless shelters because they don't feel safe there, or they don't want to be separated from their pets, partners or belongings. Avivo is changing that model.

At 7am in Mendota Heights the grass on the soccer field next store was covered with crunchy frost.

Frost at our farm in Stanton Township. It’s the end of the garden season.

Near Lake Hiawatha frost on the ground and roofs.

Meteorologist Aaron Shaffer@ashafferwx.bsky.social

What's everyone's frost or freeze report? We seemed to not frost in South Minneapolis at our house - airport was at 38° at 7am, but I hear Eden Prairie Airport was 31!

Just north of St Mary’s Cemetery, we had frost on the car roof and a very thin layer of ice on the dog’s outside water dish.

Prospect Park was mostly clear of frost, but I saw some frosty grass along the Short Line rail right of way.

Almost forgot, cover or pick your tender vegetation tonight - even in Minneapolis or St. Paul. I am guessing/gambling it'll mostly be a frost in city limits vs. a freeze, but be cautious in that gamble. Dewpoint is below 30 degrees + calm winds could equal trouble for gardens.

So heartbreaking to see what is happening in Toronto right now. I'm 100% in solidarity with these people fighting for their safety and rights. Hopefully Ontario will have a better leader in the future. ✊

This year, federal agents terrorized our streets, killed our neighbors, and detained our children. Minnesotans were changed forever. Michele Tafoya thinks ICE treats kids “really well.” I think ICE should be ripped apart and replaced by a system grounded in dignity and due process.

Rain is very gradually moving east, away from Minneapolis, and wind is moving in. Expect gusts to 30+ mph overnight and into Friday morning. This is radar sampled wind behind the storm, maybe a touch high vs surface, but still high - immediately. #mnwx

Chilly and wet this morning in Minneapolis, with moderate rain coming shortly. We might see a break in rain late morning, with a new wave converging over us later today. Expect somewhere in the neighborhood of 0.5" of total rainfall. #mnwx

They're almost here as of 5:48 p.m. in Minneapolis - expect light to moderate rain, depending on where you are. These are doing all of it. #mnwx

Possible showers incoming to Minneapolis and St. Paul! Not everyone will get rained on, but if you are outside or planning to be, plan accordingly. #mnwx

I’m ok. Make no mistake: this is an attempt to target political enemies and weaponize federal law enforcement. For ten years, Trump has targeted me with baseless lies and smear campaigns. This is just the latest escalation in his campaign of political intimidation. I will not be silenced.

During the ICE surge, Lisa Demuth signed a letter thanking ICE and praising Kristi Noem for her "steady leadership."

Now that we're sufficiently soaked, the rain is departing soon from Minneapolis - expect some lingering mist/drizzle not picked up by radar after but accumulating rain should be done soon. #mnwx

Our next soaker in the Twin Cities is incoming, expect rain within the next hour for much of the region. #mnwx

Looks like maybe first round of rain could pass early (incoming) and a break in rain follows for Nicollet Open Streets. Fingers crossed. #mnwx

Meteorologist Aaron Shaffer@ashafferwx.bsky.social

Unfortunately iffy weather for Nicollet Open Streets tomorrow. Looks like spotty showers closer to the beginning (morning through 11ish) and then more organized showers trying to edge in. Slow moving, so possibly with some luck they hold off until afternoon. #mnwx

Tornado forecasting had to start somewhere. In the 1880s, US Army Signal Corps meteorologist John Park Finley studied tornado patterns, built a network of observers and pioneered experimental tornado forecasts. Meet America’s first tornado forecaster: www.noaa.gov/heritage/sto... #NOAAHeritageWeek

Today’s Fall Equinox at 8:05 pm ET marks the start of astronomical fall in the N. Hemisphere and is when the Sun is directly over Earth’s equator. Now through the Winter Solstice, the Northern Hemisphere will receive less ad less direct sunlight as Earth continues along its tilted orbit.

Some light rain or sprinkles possible over the next couple of hours as some dying rain showers move north. It's a race against time for them - but either way another cool and damp day. Quite a shift from our intensely hot summer. #mnwx
