A host of meteorological indicators are converging on a weather scenario that points to a hot week for the Chicago area with temperatures expected to approach or top the 90 degree mark on most days.
After several false alarms, a portion of the large dome of hot air that has been baking the West much of this summer is finally making inroads on the Midwest and should arrive for what appears to be an extended stay by Tuesday. Any cooling from Lake Michigan will be felt only along the immediate lakeshore as a hazy sun beats down on the city in the light wind regime.
A frontal boundary will approach the region by late in the week, offering up a threat of some cloudiness along with some showers and thunderstorms that could keep the mercury just below the 90 degree threshold on Friday.
The week's hottest weather could arrive Saturday as gusty southwest winds push the boundary to the north and send the mercury toward the middle 90s.
WGN-TV Chief Meteorologist Tom Skilling and the WGN Weather Center staff provide daily coverage of weather in the Chicago area.
