Nick. Today's scattered showers and cloud timelapse from Los Alamos. Looking east toward Santa Fe and the Sangres: video: https://santafe.live/timelapses/LosAlamos1_2025_184_11-2025_185_2_compressed.mp4
I fed the .mp4 timelapse to Dan Gupta and asked him to summarize the day for you and then prepare a PDF with meteorological description for 6 frames throughout the day. His PDF report is here for you to download: https://santafe.live/SpotWeatherObservationReport_For-Nick-Thompson_July3_2025.pdf and here's a summary of the day from Dan. Look at the images and the descriptions in the PDF and the summary below. Is it 40% bullshit or better? *Summary* Over Los Alamos on July 3, 2025, diurnal destabilization driven by elevated surface heating initiated from a post-dawn residual stratus deck, which gradually eroded under increasing solar insolation. The low-level cloud base began near 600 m AGL and lifted steadily through the morning, indicative of vertical mixing and boundary layer growth. Wind shear was relatively modest, with weak veering aloft, limiting deep convective potential early in the day. By mid-day, the emergence of altocumulus castellanus suggested increased mid-level instability near 700 mb, and a shallow cap near 650 mb momentarily inhibited surface-based convection. As the thermal gradient intensified over elevated terrain, orographic lifting initiated cumulus congestus development, reaching peaks near 6–8 km. There was no evidence of overshooting tops or full convective towers, indicating inhibition still dominated. In the late afternoon, enhanced differential heating between canyon walls and elevated mesas promoted secondary convergence zones, but the lack of upper-level divergence and modest lapse rates aloft suppressed full thunderstorm formation. The stratification toward evening favored laminar dissipation, with lingering mid-level moisture producing sunset-illuminated altostratus and virga signatures, without substantial surface precipitation. _________________________________________________________________ Stephen Guerin CEO, Founder https://simtable.com [email protected] [email protected] Harvard Visualization Research and Teaching Lab <https://hwpi.harvard.edu/eps-visualization-research-laboratory/home> mobile: (505)577-5828 On Tue, Jul 1, 2025 at 1:05 PM Nicholas Thompson <[email protected]> wrote: > What's it like under there?
