Lightning, rainbows, and clouds across northern Arizona

July has turned out to be a good month for photographing weather across northern Arizona. For a few days in the middle of the month I was able to capture images of lightning, rainbows, and colorful clouds at sunset near Sedona and the Grand Canyon.

The conditions on 13 July 2015 were about perfect for late afternoon photography. Deep moisture was present across the eastern half of Arizona while very dry air persisted across the west. This allowed storms to form over the eastern half of the state while clear skies allowed the setting sun to shine brightly on the landscape near Sedona.

Cathedral Rock was nicely illuminated by the setting sun and shafts of rain caught the sunset colors. A faint rainbow was also present adding an additional dimension to the scene.

After the sun set, I repositioned so that I could catch twilight colors in the western sky and lightning from additional storms. In the background can be seen the highly textured shape of the Cockscomb.

The next day proved to be difficult for lightning photographs but the sunset colors on the clouds over Cathedral Rock were very dramatic.

Sensing a need for a different location, I travelled to the South Rim of the Grand Canyon a few days later (16 July) hoping to get some lightning photos over the canyon. The atmosphere had stabilized some and storms were much weaker and very little lightning was observed.

A very nice consolation photo, indeed!

Rainbows and lightning in the Arizona Desert

Over the weekend tropical moisture and an area of low pressure interacted to produce showers and thunderstorms—and even a few severe thunderstorms—across northern Arizona. A quick look at satellite and radar data convinced me it was worthwhile to drive down the hill from Flagstaff to Sedona to capture some lightning photos.

Light rain began to fall as I approached my first photo location and a horizon-to-horizon rainbow appeared. As I arrived, the southern end was quickly fading while overhead and to the north the rainbow remained brilliant. And, then, for just a brief moment, the southern end brightened again and a swath of color painted itself across Cathedral Rock. In another moment it was gone. Note, also, that there is a supernumerary rainbow visible in a portion of the bow. Supernumeraries are the closely spaced greenish purple arcs on the inner side of the primary bow.

As these storms moved to the northwest it was time to reposition and hope for some lightning. The first image shows a thunderstorm moving across the Verde Valley and the storm is lit up from below by the lights in the town of Cottonwood. Sunset colors are still faintly visible in the west and stars can also be seen. This was followed by a bolt with numerous downward stepped leaders and a brilliant return stroke.

Not too bad!

Sedona sunset and lightning

It’s the middle of July and the North American Monsoon is in full swing now with near-daily thunderstorms across northern Arizona. It was time for another photo shoot in Sedona in hopes of getting great lightning shots with Sedona’s famous redrocks as a background. A few nice sunset photos wouldn’t be too bad, either.

After a quiet afternoon in Flagstaff with little in the way of thunderstorm activity, clouds finally began to develop in the late afternoon. A quick check of the radar data using RadarScope showed that thunderstorms were developing over the higher terrain of the Mogollon Rim and were moving slowly to the south-southwest. This would put some of these storms near or over Sedona in an hour or two. Time to jump in the car and head south.

It began to rain as I drove down the switchbacks into Oak Creek Canyon. This was the site of the Slide Fire in May and the threat of flash flooding exists whenever moderate-to-heavy rain falls in the area. Luckily, rainfall remained light and there was no threat.

My first location was on Upper Red Rock Loop Road with a view to the east so that I could capture lightning along with some of Sedona’s famous rocks — Courthouse Butte and Cathedral Rock. No luck today — but I did get some good images the previous day from this same location. Still, I was able to get several lightning strokes over the cliffs and create a composite image.

As the sun began to set, the activity shifted and it was time for another location and I headed to the Sedona Cultural Park. The sunset colors just got better…and better…and…well, you get the idea. And there was also plenty of lightning to shoot as twilight unfolded.

All-in-all, a very successful photo shoot.

Lightning in Sunset Crater National Monument

A late afternoon storm developed near the San Francisco peaks the other day and I hoped that I would be able to get some lightning images as the sun set and twilight developed. Unfortunately, the initial lighting strikes were too close and I had to retreat to the car for safety. By the time I was able to reset the storm had drifted north and the best lightning was striking behind the cinder hills. Still, the light of the setting sun was making the rain glow.

As the sun set the colors faded into blue twilight and the storm moved between two cinder hills for a brief time allowing the lightning to appear in the gap.

Lightning at twilight over the Painted Desert

The North American Monsoon is in full swing with daily thunderstorms — all presenting opportunities for photography. I finally got a chance to photograph some twilight lightning while looking out over the Painted Desert from — where else — the Painted Desert Overlook between Sunset Crater Volcano National Monument and Wupatki National Monument.

Shortly after these images were taken rain began to fall and I called it an evening. The drive back home was slow and difficult in the torrential downpour that was constantly interrupted by brilliant flashes of lightning. It was one of the most active nights of lightning in the Flagstaff area of the season. And it did rain hard! One automated raingage reported over 4 ½ inches in two hours.
