During the next 24 hours, clouds are expected to slowly increase and thicken in advance of a slow-moving low pressure system approaching from the west. With the low meandering through northern Illinois Monday and Tuesday, associated clouds, showers and thunderstorms, along with easterly winds will keep temperatures in a very narrow 10° range.
Readings may hover in the 60s for the better part of a 48 to 72-hour period. Should temperatures reach 70° Monday and Tuesday, there is a good chance highs will stay in the 70s the rest of the week. This would give Chicago a record-breaking string of 15 days with 70° highs dating back to Aug. 26.
As Tropical Storm “John” is forecast to weaken and move out to sea leaving the Baja coast behind, the remnant of “Ernesto” dies out over New England. However, the east coast will be threatened anew by heavy rains during the week ahead.
