Unsettled Weather for Much of Next Week

There is a front lying across central Illinois that is stationary, and begin moving toward the north as a warm front later tonight.  Widely scattered showers and some isolated thunderstorms may pop up late tonight. The front will approach the Stateline on Monday, and  temperatures will warm into the middle 70's.  On Monday night the warm front will move northeast though the Stateline leaving the area in the warm sector.  Overnight lows on Monday night will be well above average for this time of year....  bottoming out in the mild low to mid 60's.  Illinois will be on the warm sector all day on Tuesday, and temperatures will soar all the way into the middle 80's.  A new cold front will approach the area later in the afternoon sprawing a line of  thunderstorms that will end overnight after the front pushes off to the southeast, but it will stall out rather quickly over central  Illinois, and begin to move back toward the north as warm front by Wednesday afternoon.  So thunderstorms will become a possibility once again later on Wednesday, and continue through Wednesday night,  as the warm front approaches northern Illinois from the southwest.  Once again our region should be in the warm sector on Thursday allowing temperatures to reaching the low to middle 80's.  Scattered thunderstorms will develop again overnight ahead of the advancing cold front.  That next cold front looks like it will move through the local area early on Friday morning ending the thunderstorms once again.  High temperatures will be close to average on Friday and Saturday.  Saturday and Sunday are a long way off forecast-wise, but right now it looks like the weekend will be mostly sunny with pleasant temperatures around 70 degrees.
Enjoy the rollercoaster ride.
It will be a fun week in the weather world.
