Nusiance Shower...Maybe a Thunderstorm on Sunday

High pressure is sitting over lower Michigan tonight.  Low pressure is over the Oklahoma panhandle, and a stationary front snakes eastward across Kansas, southern Missouri, and southeast through Tennessee.  Warm moist air from the Gulf is riding up and over the front, and may generate a few showers overnight, and there is a slight chance of showers and thunderstorms on Sunday. Under mostly cloudy skies the temperature will top out in the upper 70's.  A warm front will advance into central Illinois by late Sunday night giving the Stateline a good chance of showers and thunderstorms. With that system gathering energy and moisture, there could be some severe thunderstorms on Monday with damaging winds and large hail.  The storms will come to an end on Monday night with a drier air mass from the Rockies pushing into Illinois. The high pressure will move into Minnesota on Tuesday giving northern Illinois sunny and pleasant weather on Tuesday and Wednesday with high temperatures in the upper 70's along with comfortable humidity levels. By Thursday the high will have shifted all the way east to Buffalo, N.Y., and a strong warm front will be approaching from the plains.  The high on Thursday will be around 87 degrees, and on Friday, hot and humid air will make for a very steamy day with a high around 95 degrees, and heat index's likely to be above 100.  On Saturday a cool front will approach, and thunderstorms will be possible.
