Notes:
Strengthening of broad LLJ implies onset of very significant moisture transport into KS as reservoir
of higher mixing ratios over OK at 0600 UTC accelerates nnewd in conjunction with strong isentropic lift.
Forward-propagating storms in northwest KS will shortly intercept this increasing moisture/lift.
