Dryline now a couple counties into OK coming in from the west. HRRR now shows abrupt line of initiation along I-35 corridor at 22Z, with 0-1km SRH near 200, 45-50kt shear. The minefield of convection progged further north in S KS and its eventual upscale conversion to an MCS are inclining me to take the safer dryline play (well, that and the horrible AT&T data coverage north of the OK-KS border). LCLs don't appear to be much worse in the OK region compared to SE KS. With convection working its way south nearly to OKC Metro with 3 hours of additional daylight to play with, should make for a good chase and easy east-west exit options when the line starts to congeal.
