We issued a tornado warning for the Montague County Tx storm. The sfc rotation track was very useful in helping to draw the polygon as the velocity data was very messy with de-aliasing. This made the sfc rotation track a bit messy, but still easier to see the general idea of what was going on with rotation than the SRM data.

Near Henrietta, TX. Take appropriate shelter now if you live across northern Clay Co, TX.
Occurred at 4:45 pm cdt.
The rotational track product did a great job really highlighting the Moore tornado start to finish. The white to blue values around 19 s-1 seemed like the point that if you didn’t have a warning out you should have, but you likely would have no lead time if you waited for 19 s-1.. The red values 11 s-1 on the sfc rotational track would have given you some lead time on this tornado and were a little easier to view than the 0.5 and 0.9 base data at this time. The mid level rotational tracks were more of a mess but the white/blue 19 s-1 in the mid level rotation would have given some lead time. This strong mid level rotation was present near Bridge Creek prior to tornado genesis.
