Oklahoma to Hereford, Texas
We arrived in Oklahoma City and headed towards Amarillo for Saturday's
forecasted severe weather.
We positioned just north of Adrian, Texas to observe a
severe storm that had developed. The storm became tornado warned
at 7:22 PM. We needed to pull back as our position was soon to be
overrun by the approaching hail and rain. The picture below taken at
7:26 PM CDT has the storm where the rotation was located with the wind
farm in the foreground.
The approaching rain and hail. We pulled back
south and then moved east on Interstate 40 to get back in front of the
storm. Within the storm was strong rotation and we encountered
heavy rain and hail as we drove parallel just south of the tornado
warned storm. The storm quickly became rain wrapped where the
strong rotation could be seen on radar.
The National Weather Service Storm report shows that a
confirmed tornado was documented

Vega, Texas before ending the day in Hereford, Texas.

Tornado warning received on our cell phones at 9:03 PM on the storm we
were trailing. Due to darkness we followed just behind the hail
core and strong rain.
The route south through Miami, Texas was blocked by the train that was
stopped due to the active tornado warning. We encountered a
flooded underpass from the storm which also prevented access past the
tracks. Photo by George Kourounis. The tornado warning moved
further south and the train was able to depart clearing our route to

Monday's plan is to work the southwest Kansas area for storm initiation.
The Storm Predication Center's issued a 5% probability that a tornado
would within 25 miles of any point.
We followed a storm that developed near Jetmore, Kansas at 6:41 PM CDT.

The Storm Predication Center had most of Kansas in a 5% probability for
a tornado forecast. After a while we worked our way back down to
Liberal, Kansas. At 9:43 PM CDT a brief tornado about 60 miles to

We picked up some 1 3/4 hail and worked into position near the wall

would be below. Two tornadoes were produced southeast of Spearman,
Texas. Doppler Radar image time is 3:37 PM CDT or 20:37 Z.
This storm produced an EF-0 Tornado at 3:36-3:39 and at

Thursday May 9, 2019 - Fairview, Texas to
Working to move south and west for later day storm initiation.
Likely severe storms with hail with a slight chance for tornadoes.
Storms became active throughout the area and we worked
around them to see if we could get any better views. Trees, rain,
and low cloud cover restricted views of the storms.
We worked south of Hungerford, Texas. The storms
were topping over 50,000 feet as shown above.
