Oklahoma Mesonet readings over the last 24 hours. Can you spot the tornado impact?

Get a load of this meteogram from the Oklahoma Mesonet in El Reno, OK, tweeted by Base Velocity, LLC. Not only did it measure a 150 MPH wind gust around 4:30 PM, it also recorded a pressure drop to 940 millibars and a complete loss of solar radiation around that time — suggesting it was pitch black outside at the time of the tornado. I’ve seen early reports on Twitter suggesting pretty serious damage there. Here is a Doppler base velocity image from around the time of the tornado strike. Extremely strong couplet in play. I hope people heeded warnings and protected themselves from what appears to be an extremely violent tornado.
