Tornado Outbreak!

A dangerous tornado outbreak is in the making for this evening and overnight.  Tornadic supercells have already formed in Oklahoma, Kansas, and Nebraska this afternoon with several reports of tornadoes touching down.                                (Preliminary Storm Reports)

Thunderstorms will continue to develop in the Southern Plains as we near the dusk hours which will make for an even more dangerous situation.  The SPC has a high risk for severe thunderstorms from Nebraska down into central Oklahoma.  High risk days are very rare and this needs to be taken seriously.  Violent EF2-EF5 tornadoes are possible this afternoon and overnight; these storms will not weaken overnight!                                                    (Risk Area Per SPC)

The best chance for violent tornadoes will be from Nebraska down into the OKC/Norman Metro areas, but southern Oklahoma and northwest/north Texas need to watch out too because if a surface based storm gets going in one of these areas a tornado will be possible too.  The main limiting factors, for southern Oklahoma/north Texas,  is the CAP and strong forcing being located just north which will help inhibit thunderstorms.

                                                                  (Tornado Probabilities)

All the parameters are coming together at the most dangerous time of the day, so again, please be alert to your weather conditions; these storms will continue into the night and will even be enhanced due to the LLJ which will contribute to the winds changing with height.  This could be a record outbreak for the Southern Plains!  Everybody please be safe tonight and share this to spread the word about this dangerous setup. 

Just a side note, this is the one year anniversary of the deadly Tushka tornado that occurred on April 14, 2011.  We at Texoma Weather/primoweather.com commend the people of that community as the continue the recovery process.
