The past few days have produced interesting storms across northern Arizona.
An isolated storm developed around sunset and produced both wonderful colors and lightning. Most of the lightning, however, was on the other side of the updraft so the storm instead was lit from the inside like a lightbulb. The storm colors and lightning was nicely reflected in the waters of the Kachina Wetlands.
A few days later a large line of convective storms moved southwestward across the state and produced a haboob in the lower (and drier) elevations. As the leading edge of the rain-cooled air moved across the San Francisco peaks the clouds quickly enveloped the mountains. About an hour later, the shelf cloud arrived in Sedona and new storms began to develop.
The North American Monsoon has been sputtering—for lack of a better term—the past week or two. We get a few days of storms followed by a hot and dry period. Finally, however, moisture is beginning to increase and we are seeing more storms. I have tried several times this year to get great photographs of storms and lightning but my success rate has been pretty low.
Here are a few photographs from the past week.
And, finally we have a time lapse of the same storm that produced the lightning above. The video is 200x real time; from the motion it can be seen that the storm has some slow rotation. This storm moved off the higher terrain and became severe as it neared the Camp Verde area.
The weather models have been consistent with forecasting a significant increase in storm activity next week.
A late-season winter storm brought snow to the high deserts of northern Arizona. An early morning check of weather conditions indicated that Sedona airport (KSEZ) had reported snow. And satellite data showed an area of fog in the Verde Valley, including Sedona. This had the potential to be a great opportunity for photographs.
The early morning visit to Sedona was worth the effort. And the trip home included a stop at the recently re-opened Indian Gardens Cafe in Oak Creek Canyon.
This is the second year in a row in which the North American Monsoon has failed to deliver its normal weather to Arizona. The monsoon had a late start in July with only a few isolated rain events early in the month and the main event starting around the third week of July. But even that faltered after a week and the final week of July was dry.
August was even worse with no measurable precipitation until after mid-month and even then the amounts were light. The National Weather Service in Flagstaff has posted some climate data for the area for August. It was the hottest August and the 2nd driest on record in Flagstaff and most of the west experienced similar conditions (Figure 1; Figure 2;Figure 3).
Photographing summer monsoon storms has been a challenge this year because there were so many dry periods. Even so, there are always interesting weather events and clouds that make it worthwhile. So here is a collection of the most interesting weather photographs from this summer.
A time-lapse movie shows that the ducks are more interesting than the convection.
Full rainbows eluded me this year butI did manage to photograph a rainbow segment.
As with rainbows, lightning was elusive this year. It was typically a case of being in the wrong place on the wrong day and at the wrong time. But I did get lucky with the following image.
And when there is no lightning and no rainbow, one can be content with the sunset.
The last few days have provided opportunities for photographing lightning and moonbows. A moonbow, of course, is nothing more than a rainbow that is lit by the light of the moon rather than the sun. Although not rare, I’ve never had an opportunity to photograph a moonbow before. Even better, it was a double moonbow. And, to make it even better, there was lightning to go along with it.
A short time-lapse video is available. The video covers a period of 24 minutes compressed into 8 seconds.
The previous evening I was also shooting lightning in Sedona and was able to capture this beautiful cloud-to-ground lightning bolt adjacent to Cathedral Rock. (Minor problem: it wasn’t in sharp focus. Oh, well.)
