A screenshot from this video shows how the winds strangely curve up, as if blocked by something, and carry the smoke plume aloft.
The wind trajectory in the video is in the reverse direction compared to Michal’s second diagram. Some people say the wind jumped the highway interstate. It changes direction like in Michal’s diagram.

Then the fire spread wider:
While according to NYT this is the most significant urban firestorm in recent history (except the Chicago fire), the residents in Athens, Greece, and many other congested towns in Greece and Italy found themselves in very similar situations. Too close to home!
While we stayed in Boulder hotel just 8km from the fires with many evacuees, my son remarked that perhaps we should be ready to leave at a moment’s notice during the night. We could still feel the wind gusts pounding on the window, and witnessed people carry their possessions in a trash bag as they had just minutes to leave their homes.
And here is the latest news:

Exactly! I want to add only a small note. What is frequently missed, is that besides the temperature gradients, there are air humidity gradients. The warmer air can go down and the colder up (counterintuitive for some) if the warmer air is considerably drier.

Subject: Re: [ERA] Boulder Initiative and a time-lapse video: Jan 2022
Dear colleagues,
concerning the wind directions. There are two issues here. First, the anomalous warmth and drought in the region (over months and more). What is the cause? According to the NYT, "the risks of the physical hazard of fire is increasing, which we know it is, for a range of reasons, including climate change and the historic policies of fire suppression and the lack of prescribed fire. ". We say instead that a major reason is the landscape drying due to improper management of vegetation cover.
The second problem is how exactly the drought has led to fire, what the winds were, what exactly could burn in the city and so on. It is an important but from ERA's perspective secondary issue. As Jan Pokorny rightly mentioned, when there are huge temperature gradients, they will equalize violently, in one way or another, which is exactly what happened. So I'd suggest to probably consider making less emphasis on explaining this particular fire but more focus on its fundamental causes and recurrent patterns.

Thank you, Jon. Sorry I haven’t been able to send it out yet, my Word document wasn’t saved on iCloud and I just came back home - had several appointments lined up for today afternoon.
I’d like to bring your attention to this fascinating time-lapse of the December 30th- a historically most destructive fire in CO history.

Boulder County, CO — Boulder County's Office of Sustainability, Climate Action & Resilience has launched a Climate Innovation Fund to support local projects focused on carbon dioxide removal (CDR) and landscape resilience and restoration. The Fund, totaling $450,000, is seeking proposals for these local projects during the application window of April 28, 2022 through May 27, 2022.
“The climate crisis is already impacting everyday life in Boulder County in the form of year-round wildfire seasons, poor air quality, and more days of extreme heat,” said Susie Strife, Boulder County Director of Sustainability, Climate Action & Resilience. “We need to continue to invest in rapid emissions reductions and the critical counterpart of restoring our atmosphere through carbon dioxide removal if we are serious about supporting the solutions needed to meet our climate goals."
Boulder County’s Office of Sustainability, Climate Action & Resilience is seeking innovative climate solutions with the goal to support carbon dioxide removal, and landscape resilience and restoration through a Request for Qualifications (RFQ). Boulder County seeks to foster local projects that respond to and mitigate climate change impacts in recognition of the fact that local government resources need to be mobilized in order to advance carbon drawdown, emissions reduction objectives, and climate adaptation strategies for increased resilience.
In developing this initiative, Boulder County has partnered with Carbon Direct Inc., a leading carbon management advisory and technology firm backed by over 40 of the world’s leading carbon scientists.
“We are excited to support Boulder County’s impressive efforts to promote place-based climate change mitigation through local carbon removal, and restoration and resilience projects,” said Sarah Federman, Senior Science Advisor for Carbon Direct and Boulder County resident. “This initiative is an essential building block towards confronting the reality of the impacts of climate change in our daily lives and creating foundations of resilience and sustainability in our communities.”
Learn more about the Climate Innovation Fund and how to apply during an informational webinar at 12 p.m. Mountain Time on April 28, 2022 hosted via this Zoom link. For more information on submission guidelines, please visit the RFQ.
Boulder County is experiencing the impacts of a warming climate in the form of reduced snowpack, earlier snowmelt, increased risk of high intensity wildfires, extreme weather events, and an increased number of “high heat” days. Boulder County’s Office of Sustainability, Climate Action & Resilience works to ensure that we are prepared to survive and thrive in the face of shocks and stresses related to climate change while also supporting programs and policies that fight the climate crisis through rapid emissions reductions and carbon dioxide removal.
