notes: warm front associated with low centered in western Kansas has passed over Lawrence. thunderstorm and shower initiation did not form as the front approached with fairly dry air present. Look to see this system to move slowly east to southeast. Upper air support will be greater tomorrow with the trough axis located in central Colorado then passing over western Kansas by Sunday morning. Isotropic lift will also be greater with temperature gradient over Kansas, Nebraska border. Vorticity max advection will be at 12 Z Sunday. CAP will be greatest 00Z Sun, this is also best area of isotropic lift as well. Low level jet will weaken some and be more westerly by afternoon Saturday into evening. Both models are saying best chance 6Z-12 Z for precipitation. RUC is predicting LI -4 to -6 range through 6Z-12 Z, CAPE 800-900 range.
