Won't go into much detail as I'm low on time but a potent setup may unfold Wednesday 17th across much of the southern plains. Tornadoes are a good possibility with the great low-level shear values associated with the system. This will definately not be an easy chase with storm motions around 40kts and a bad road network. A lot has to unfold right though for this event to live up to some hype its already getting so I'll leave it at that. In the mean time, here's what OUN and SPC are saying:
...THE ENVIRONMENT WILL BE
FAVORABLE FOR SUPERCELLS WITH VERY LARGE HAIL/ LOCALIZED DAMAGING
WINDS. AND...LARGE LOW-LEVEL HODOGRAPHS BENEATH A 40-50+ KT
SOUTHERLY 850 MB JET WILL SUPPORT THE RISK FOR A FEW
TORNADOES...SOME OF WHICH COULD BECOME STRONG ACROSS PARTS OF
CENTRAL/EASTERN KANSAS AND OKLAHOMA.
