Sunshine fades as the clouds increase

The remnants of Lee have begun to lift north into Ohio and will eventually move west into central Illinois by Friday.  As this happens the clouds will be on the increase from east to west late on Thursday.  A few light rain showers will be possible, but I believe the threat will be east of the immediate Stateline area.  With several days of cool, dry air it's going to take some time for our atmosphere to saturate.  Besides the cloud cover the winds will also increase Thursday and Friday as the difference in pressure will be high between the cut-off low and the high pressure in the northern Plains.  Winds could occasionally gust to 30 mph during the afternoon.  Rain showers will be possible into Saturday but the cut-off low will weaken and lift east which should give us a dry day on Sunday.
