Big warm-up imminent—80s Monday/Tuesday
Temperatures will rise as a warm front approaches from the west today, a prelude to the first 80° temperatures experienced in the Chicago area since a high of 82° was recorded nearly two weeks ago on Sept. 17. In fact, if forecasts prove correct, 80° highs could be recorded 3 times this week—Monday, Tuesday and Saturday—just one short of the entire month of September’s total (4). Even with a midweek cool-down, highs are forecast to reach only into the 60s Wednesday and Thursday, temperatures are projected to average nearly 11° above normal for the next seven days. Though periodic showers or thunderstorms are in the forecast for the week ahead, it appears that Chicago will be positioned well south of the area of strongest frontal lift and available moisture. Oct.1-7 rainfall could well total less than a quarter inch here with one to two-inch totals possible across central Wisconsin and Lower Michigan.
