More Heat on the Way

High pressure sprawls from northern Wisconsin to another center over Missouri to yet another over the Colorado.  It will be mostly sunny and very warm today with a high in the upper 80's.  A disturbance over South Dakota has spawned an area of showers and thunderstorms this morning over the eastern Dakota's into western Minnesota.  High clouds from that complex will overspread the Stateline this afternoon, but will be the cirrus type that will allow the sun to shine through.  Winds will be light today under the influence of high pressure.  Tonight remnants of that disturbance will be edging eastward, and may cause a few stray showers and thunderstorms into southwestern Wisconsin and far northwestern Illinois. The showers and storms are not expected to reach into the north central part of Illinois because the residual dry air in place here.  It will be partly cloudy tonight with a low near 60 degrees.  Clouds from the disturbance to the west will make for a partly cloudy start to the day on Wednesday, but the disturbance will weaken, and fade away as the large high builds into the area once again.  This time, however, the Stateline will be on the west side of the high, and with southerly winds developing, and full sunshine, the temperature will top out around 90 degrees.  Heat and humidity will continue to build  with high temperatures on Thursday and Friday in the middle 90's.  A cool front will push southward across the area early Friday night as the remnants of Isaac reach into southern Illinois.  It will be cooler on Saturday with a chance of showers and thunderstorms.  Chances of showers and thunderstorms will persist through Sunday.  High temperatures on Saturday and Sunday will be in the middle 80's.  High pressure will make an attempt to take control of the weather on Labor Day.  Skies are expected to be partly cloudy as afternoon temperatures top out in the middle 80's once again.
