A "dirty" high pressure over the Great Lakes will move slowly eastward on Sunday.  There is a southwesterly flow over the top of the high accounting for high level clouds over the weekend.  Temperatures will remain a little bit on the cool side because of the continued cloud cover from Sunday through the early part of the week. A disturbance moving out of the southern plains on Sunday could scatter some showers into the area on Sunday evening.  It will pass well south of our region on Sunday night, but there will be enough of a moisture feed in from the south that showers will be likely after midnight, and enough instability may be in place to cause some rumbles of thunder.  The low will stall out over southern Indiana, and we will have a continuing chance of showers on Monday, and some may even pop up on Tuesday. By Wednesday high pressure will be in firm control of Stateline area weather, and a warming trend will begin, and continue right into next weekend.  Temperatures will be well into the 70's by late in the week under the influence of a southerly breeze and mostly sunny skies.
