The remnants of Isaac are currently on a northern track, but will be swept east by a frontal boundary also moving to the east. Heavy rains may begin to train over areas as the system takes time to shift directions. Thus, heaviest rains can be expected in Central Illinois.
Kirk is in a weakening phase at this time, not moving to the northeast in accordance with a frontal boundary guiding the tropical cyclone along. I am anticipating Kirk dissipating in the next couple of days, before shooting towards Europe.

Leslie's track is not well known at the moment, however a general out to sea consensus has been formulated by the models. The frontal boundary guiding Kirk appears to be the instigator, and this out to sea solution appears very valid.
