5-24 Lightning

Another venture out west of Ladd, IL to shoot some lightning on 5-24.

5/17-5-24 Chasing with CoD

Since I've been lazy blogging, I figured I should probably make one big post to get back on track. This post contains the rest of the College of DuPage storm chasing trip (trip #2) that ran from 5-14 to 5-24.

Roll/Leedy storm. Best picture of the trip IMO.

This storm eventually went on to produce the Bowdle tornado (EF 4 rating).

Ahhh! Sometimes you don't need a tornado to make a great photo!

5/16 Crapvection

Yesterday (5/15) was a complete bust with no ‘cool’ images worth showing. We ended the day in Sonora, TX with beers and great stories after another long day of driving. This morning, we again targeted the Fort Stockton, TX area and actually got convection to develop via the Del Norte Mountains to our Southwest. It was apparent during morning analysis that anything convection was going to have a hard time becoming sustained in the weak atmospheric wind shear and lack of mesoscale convergence. We drifted south to catch up to these storms, but they could not sustain themselves without the aid of the mountains. After grabbing some dinner, a nice storm formed to our northwest and began moving toward our location. Unfortunately, as daylight began to wane, so did the storm. Below are a few images despite a rather unexciting day in the beautiful country of southwest TX. Off to Odessa, TX for a good dinner and beers. Tomorrow looks to be the best day of the trip to this point...

Storm NW of Midland before sunset. I believe Dr. Walker Ashley was in very good position for this storm, so keep an eye on his blog for a post.

Saved by the Bell

Targeted the Clinton, OK area like most and got a pretty decent sunburn. Drifted north closer to the warm front as many convective towers failed to sustain any sort of deep convection. Right as we were about to call of the chase, a couple back to back strengthening radar scans from the storm SW of Woodward caught my attention. As we closed in, the storm became tornado warned. While we were not able to witness any sort of low-level rotation, we were treated to some great structure right before sundown. A saving grace for a disappointing day...

2010 Chase Season Starts with a Bang


The 2010 chase season started with a bang for me on Monday. After starting the day in Springfield, MO, it was quite evident that all of the ingredients necessary for tornadic thunderstorms were coming together along the dryline in western OK. After stopping near Wellington for a quick sandwich and data crunching, a storm began to fire just east of the dryline near Chester. The storm quickly induced tornado warning and we were able to intercept it near Lambert. Its appearance was 'elevated' at best during a time when the inflow region of the storm sat nearly stationary for ~15 min. on a day when storm motions were over 40 kts. to the northeast! Due to poor road options, we were forced back east on highway 11 which presented a major chaser convergence issue. By this time, the RFD had kicked and a very strong low-level circulation was present on radar. Since we were chasing the storm east as it was crossing Highway 11 from the southwest, we inevitably crossed the damage path. While some of the damage appeared tornadic in nature, very strong (I can verify :]) RFD winds were likely the culprit to many shredded trees and downed power lines. We were able to witness a rare anti-cyclonic tornado just east of Cherokee. While it was only a brief spin-up on what turned out to be a very big day for tornadoes further to the South, it was a good way to dive right back into chasing after a very long winter.

Walnut size hail. Some was as large as tennis balls!

As for today...

I honestly think that today's setup is much more chaser-friendly. The environment down along the Red-River near 00Z is progged to be pretty favorable for supercells with at least an outside shot of bagging a tube before the storms turn to HP bombs. Also, storm motions will be much more manageable. If there is just enough lift along the retreating boundary, this could turn out to be a sleeper day that many have written off...

I will be adding some videos later today/tomorrow...
