Forecast Revisions: Clouds Holding High Temperatures Down, Rain Chances Overnight

We have a much more complicated forecast with some major revisions this afternoon. The complex of showers and thunderstorms from northwestern MO, which moved into the area early Saturday morning, ended up becoming larger and more numerous than what was initially forecast.

Lingering clouds have hung around, which suppressed our high temperatures for the day; those are just starting to clear the area, although some clouds remain east of the Mississippi River and south of US 36 in Missouri. The good news is that heat indices will be lower today in the eastern and southern sections of the viewing area, although Lee County, IA, as well as Scotland and Clark Counties in MO and northern parts of Hancock County in IL have seen more unabated sunshine, so high temperatures there could still climb close to the upper 80s, with heat index values near 90 degrees. Everyone else should remain 5-8 degrees cooler than initially forecast yesterday, though humidity levels will continue to increase.

Will Sunday hold true for more oppressive heat and humidity values? What are our precipitation chances for the next 48 hours? I will also have a fresh forecast to answer these questions, and I'll also examine the long-term (5-7 day) outlook coming up tonight at 10 PM!
