As of now, a deep trough is slowly moving northeast towards Nebraska. Eventually, a cold front will latch onto this system and pull up the dry line to initiate storms tomorrow evening. It can be expected that supercells will dominate the landscape tomorrow in northern Oklahoma and south central Kansas.
Here is my graphic for tomorrow.
The exact coverage of severe weather is not known right now, but enough parameters are in place for a tornado outbreak to happen tomorrow.
Supercells will form in central Oklahoma and south east/south central Kansas, where the greatest tornadic risk is. As the cold front overcomes the dry line overnight, these storms will shift to a more linear threat, with squall lines and derechos possible.
Chase Spot: Enid, Oklahoma.
**Be warned that this situation is extremely dangerous and life threatening. Make all preparations now and do not wait until the last minute. Repeat: This is life threatening and very dangerous.**
