Sunshine and warmth to return with abundance

Cloudiness and brisk northeast winds brought the area its coolest weekend since mid-May. High temperatures at O'Hare International Airport failed to pass 70 degrees, helping the city register four straight days of below-normal readings. The chill was not significant, with the period of Thursday through Sunday posting a deficit of only 2 degrees. The early taste of autumn was in sharp contrast to the opening days of September, which produced three 90-degree days and averaged 10.8 degrees above normal. Double-digit temperature surpluses are forecast to return later this week as the area undergoes a warming trend, aided in part by Hurricane Florence, expected to reach the Atlantic coast on Thursday. Sinking air on the periphery of this storm will help keep skies clear across the Midwest and result in steady day-to-day warming. Daytime readings are expected to reach the mid- and upper 80s by Thursday, a level about 12 degrees above normal.
