North American Monsoon–August 2024

A curtain of light rain from a dissipating thunderstorm is brilliantly illuminated by the setting sun.

Storms in August were more plentiful than in July although there were still some extended breaks in the monsoon. Rainbows remained elusive for me. I was able to photograph a few that displayed short segments but I never captured a full rainbow. Lightning, on the other hand, was plentiful and I did well in that genre.

Here is a partial summary of August monsoon photography.

Mormon Lake Overlook is a short drive from Flagstaff and affords an amazing 360° view. This was one of the many days with only a partial rainbow but the juxtaposition of the rainbow and the tree in the grasslands of Anderson Mesa was a pleasing composition. A few minutes later the Sun beautifully illuminated some light rain falling from a dissipating thunderstorm. The color was intense and only lasted a few minutes.

Aspen in the Fall

The aspen leaves have now mostly fallen to the ground with only a few patches of color left. It has been a good year for leaf peeping and I was able to capture several images that I like. But I have also captured some good photos over the years and this post highlights some of those.

My favorite is this photo taken while mountain biking in the Inner Basin of the San Francisco Peaks. Shot with fill flash and an ultra-wide angle lens.

One of my earliest photos, also in the Inner Basin, was shot on Fuji Provia film in 2005. The remaining photos are from 2008 through 2022 and are, of course, digital shots.

And, finally, we have some weather

It has been a very dry autumn and early winter around these parts—but that finally changed as a winter storm moved across the area yesterday and today. On Tuesday afternoon clouds began to increase across the area and there was a cap cloud draped across the San Francisco Peaks.

Most, but not all, of Arizona received precipitation including Flagstaff. We have been without any significant precipitation since September 27 when 0.07″ of rain fell. Since then, we’ve had 0.01″ on November 17 and a Trace on December 21. That’s it. It’s been the driest period on record and the second latest first snowfall of the season. And it’s been warm.

Rain began to fall around 7:30 P.M. Tuesday evening then switched to snow around 10:15 P.M. as the cold front moved across the area. Prior to frontal passage we had several rounds of thunderstorms. At least one of these thunderstorms exhibited extreme right-mover characteristics as well as some weak rotation suggesting it may have been a supercell. With this winter storm Flagstaff received ~5″ of snow and 1.19″ of total water.

Although it was still mostly cloudy this morning, there was a gap in the clouds along the eastern horizon allowing sunshine to briefly illuminate the peaks shortly after sunrise.

The San Francisco Peaks are almost completely wrapped in clouds with only the summits visible. A few minutes later, the sun had risen high enough that it was above the clear gap and everything turned gray again.

This will be a short-lived episode as the forecast indicates a quick return to warm and dry conditions across the southwest.
