Rain Moving in Overnight.

High pressure over Lake Huron is slowly giving up it's grip on the Stateline. Our region has had some pleasant weather associated with this high, but as a system moves out of the central plains  it's influence will be felt across the area overnight into Wednesday and Wednesday night beginning with the threat of some showers this later tonight, and possibly some thunderstorms.  Several areas of thunderstorms have broken out as of 9:30 pm cdt over the plains, and parts of the midwest stretching from the Dakota's and Minnesota across Iowa and Missouri into Nebraska.  There have been some severe thunderstorms already reported over Iowa and northern Missouri.  No severe weather is espected to develop into northern Illinois tonight or Wednesdsay.  Low pressure near Kansas City will move to near Quincy, Illinois by sunrise on Wednesday. A warm front stretches southeast out of the low across the southern tip of Illinois. Gulf moisture running up and over the front to our south will provide moisture to develop the precipitation into northern Illinois.  Wednesday will start off rainy  with some embedded thundershowers. The showers will taper down a bit during the afternoon, but there will still be a good chance of more showers and thunderstorms on Wednesday night that could linger into Thursday.  After a dry day on Friday, a warm front will approach on Saturday, generating some showers and thunderstorms, and warming temperatures to around 80 degrees.  The warm front will sweep off to the north on Sunday moving tropical air into the area with heat and humidity leaving the Stateline near 90 degrees on Sunday afternoon.  On Monday the high should be in the low 90's.
