Thank you, Anthony. We have some of the world’s best meteorologists right here in OKC, Moore, and Norman, for obviously good reason, and it is sure nice knowing that another of the greats is out in California watching out for us here too. Thanks for documenting this solid information.

Watts Up With That?

The map below shows ‘Tornado Tracks Streak Across Oklahoma’ as measured by doppler radar.

The rotation of tornadoes creates a distinctive signature in radar data, and can be used to estimate the track that the system takes over land. This image shows the rotational velocity of the systems that passed over Oklahoma on the afternoon of May 20, 2013. A single cohesive structure can be seen to cut across seven counties, with Moore directly in the middle.

The rotational velocity data, being run experimentally by the NOAA National Severe Storms Laboratory, is helping to identify potential tornado structures and increase lead-time for severe weather warnings.

Here is an excerpt from the public information statement just released by NWS where they designate EF5 from damage surveys.
