Today's scattered showers and cloud timelapse from Los Alamos. Looking east 
toward Santa Fe and the Sangres:

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.

    What's it like under there?  From the radar, its a tiny storm, back 
building off the sangres and heading right for Santa Fe and Santa Fe only.  
Because it is back building, it might go on a while.  It seems so localized 
that you should be able to look out from under it in all directions.  I dont 
remember thunderstorm coming from the East all that often.  There is a 
blossoming of moisture headed your way from both the ATlantic and the Pacific.  
If it gets there you may actually catch up from your drought winter.  Well 
done! N
