Chase Accounts

June 1, 1999
Pictures from this day.

On this day, Scott and I decided to target Cook and Grayson counties in North Texas. We arrived at our target area at 2:00 p.m., off Hwy. 82 near Gainseville and decided to get some readings with Scott's weather station. Strong southerly winds were noted as were high temperatures and very high dewpoint readings. At 3:30, we began watching towering cumulus devloping to our west and waited for them to move our way, and that, they did. At 5:00 p.m., a tornado watch was issued for the area as the convection pushed closer.

At 5:30, we picked out the most promising storm which was located near Sherman, TX. However, several other storms also began developing in close proximity to each other. We were not only going to have some tough decisions to make concerning which storm to intercept since most had good structure but would also have to put up with the likelihood of HP supercells. We didn't target tail-end charlie since that cell was headed for the Dallas/Ft. Worth area and chasing in a metropolis doesn't hold much apeal.

We decided to stick with our first storm and intercepted it at 6:15 p.m. At 6:30, a tornado warning was issued for the supercell. We watched some scud beginning to form under the rain free base, but the meso began to wrap up in precip. soon after. In our attempt to regain a decent view of the updraft, we ended up being treated to a hail show from a seperate nearby storm.

It was obvious that regaining position was going to be a lost cause, so we decided to turn around and intercept a different cell. After stopping, however, some small hail began to fall, and while waiting for traffic to clear, golfball and baseball size hail began to pound the road only a few feet in front of us. The hailshaft was quite concentrated, and fortunately, none of the large hailstones struck the car. However, it made for some great video, probably the best we got that day.

After filming the hail, we began backtracking, and after driving through an enormous amount of heavy rain, we finally found a rain free area near the Texas/Oklahoma border, on Hwy. 91.

At this point, we got out to get a decent look at what was going on and were to treated to a impressive double rainbow.

After choosing a storm to intercept, we finally arrived in a decent position at 7:45 and observed a poorly organized non-rotating wall cloud.

In short, we ended up chasing several different cells, but we did end up salvaging this frustrating day with a brief funnel that Scott filmed. Soon after, everything conglomerated into a nasty MCS that, if nothing else, provided a decent sunset to photograph.
