July 2016 Archives

Monsoon storms got an early start on July 2nd. The night before, the HRRR model was trending toward an MCS rolling out of southern Nevada and into Flagstaff by around 6 AM. I set my alarm for 5 and sure enough she was right on schedule just west of town. I quickly threw myself and everything else in the car and headed out on east Route 66 to watch it plow through town. I love watching Arizona storm clouds when they’re in high-speed mode.

Since it looked like it might stay interesting, I headed east to Twin Arrows—and was reminded how much I disliked the view from that exit. So I headed a bit further east to the Buffalo Range Road exit—no real foreground elements to speak of, but at least it wan’t fences, power lines and dumpsters. As the gust front moved in, a northern stretch of it lunged out and sculpted an amazing, terraced shelf.

I jumped further east to Two Guns and composed some shots of the ghost town structures with the heavy morning sky. I’ve snagged a few photo ops with the stone structures in the area, but this was my first time working with the buildings on the east side.

After that, I raced ahead to Holbrook and then southeast on Hwy 180. The line of storms was messier at this point but still had some moments of shelfy goodness to offer.

As that line weakened and moved off to the east, I had a look at the models again. Indications were that the morning cirrus shield would move on, the atmosphere would recover, and more storms would fire, despite subsidence in the wake of the morning MCS. So I headed back west and decided to explore Homolovi State Park for a little bit while convection slowly got going again.

Storms continued firing west of Leupp while tracking along and north of I-40, so I headed over to Rt 99 northwest of Winslow, then the Meteor Crater Road exit, and then back to Rt 99 south of Winslow. Storms were not as sculpted as they were that morning, but still enjoyable viewing on desolate roads.

I wrapped it up with a time lapse near Clear Creek as distant storms pulsed along a southward moving outflow boundary.

I had a nice local storm chase today. I headed west, past Wiliams, to catch storms as they started firing and hopefully ride them east with some road network testing along the way.

A little after noon, I took an exit at Welch Road a few miles east of Ash Fork to get some shots as convection was developing to the west. Somebody had kindly donated* a sofa. It was facing the wrong way, but I was not tempted by its mysterious comforts.

A couple other angles as it dared me to take a load off.

As cells blew eastward, I cruised up to Williams and took Rt. 64 north to see what would pop up next on the outflow. I stopped a bit south of Valle to watch a transient lowering, as one does when trying to randomly spot landspouts. While I was there, another chaser, Jonathan Triggs, from Grand Canyon Village stopped to say hi before making his way toward Flagstaff. Convection at this point was pretty laid back, wimpy and grungy as I circled back southeast on Hwy 180.

Although I’d been hoping for a chance of a developing cell drawing up some vorticity as the gust front passed the San Francisco Peaks, it seemed pretty unlikely at this point. So I decided to run an audit of one of the forest service roads, north of the Peaks in the no-man’s-land between Hwy 180 and 89.

I got about three miles in, before the likelihood of getting stuck and busting my car in the rocky, cratered road became too great. I stopped and found a spot to hike up a hill to get some shots of a pretty decent cell popping up north of the Peaks by that time. Lots of terrain mostly blocked the view as it continued eastward and joined a strong line of storms that moved off onto the Navajo and Hopi Reservations.

After shooting a few angles, I made my way back down toward Hwy 180 and did a bit of Coconino Cow Spotting before calling it a day.
