It's really a matter of luck - where are the steering winds. If there's no steering wind to shift it north then it'd head toward land.

Photo shows dozens of people walking & rolling bikes on a narrow sidewalk. It is crowded.

Shared use paths (bikes & peds sharing space w/o separation) are great for low density & low traffic areas.

Lyndale Ave S is neither of those.

It would be a HUGE mistake to put a shared use path here.

For safety & accessibility we need bus lanes, wide sidewalks & protected bikelanes.

Probably! Joined in the Lyndale walk yesterday - we need to get more involved in group rides.

For all the fall lovers out there, that vertical line coming in on radar represents decorative gourd season. That's our cold front that switches us from August to October. #mnwx

MJ Carpio, executive director of Move MN, telling rally attendees to contact their city council members and ask them to deny municipal consent for Hennepin County's Lyndale Ave reconstruction. A shared use path is not acceptable. Dedicated bike space is the demand.

Yes, she is also 100% for protecting wildlife and plants/trees as long as she can easily drive there from her part of Minneapolis and there are no improvements to make parks more inviting to human beings.

It's 91F in Madison in western Minnesota right now.
83F at MSP and climbing. 🌑️
Temperatures much closer to records (89F at MSP) than our normal high of 67F today.
Enjoy it. A true October cold front arrives next week.

7-day tropical weather outlook for Sept 24, 2025. Hurricane Gabrielle is over the central Atlantic. Two disturbances show high chances of development: one near the Bahamas and another east of the Caribbean.

7-day tropical weather outlook for Sept 24, 2025. Hurricane Gabrielle is over the central Atlantic. Two disturbances show high chances of development: one near the Bahamas and another east of the Caribbean.

A tropical wave over the northeastern Caribbean Sea will bring periods of heavy rain, thunderstorms, flood risk, and landslides to Puerto Rico and the USVI this morning through Thursday night. Late this week, a tropical depression is likely to form as the tropical wave nears the Bahamas.

Dense fog advisory for northeast Minnesota; best weather week of fall overall? Thick fog will blanket northeast Minnesota again Tuesday morning. Afternoon sunshine and milder temperatures will make this one of the best weather weeks of the year for many.

Happy autumnal equinox, Minnesota! πŸ‚πŸ
This could be the best weather week of fall overall.
Some morning fog gives way to blissfully mild and sunnier afternoons. β˜€οΈ
Get out there!

There’s a boundary (circled) that will stay across central Minnesota and the Twin Cities metro today.

As more moisture (my lovely arrows) gets pulled up from the south, and we heat into the mid 80s, expect more storms later this afternoon and evening.
