Chicago area not likely to see 90s for a while

Unseasonably cool weather continued to grip the Midwest and upper South Sunday, with highs failing to reach 80 degrees as far south as Tennessee. Nashville recorded a record low high of 77 degrees, while Louisville did the same with a high of just 73. Readings fell into the 30s in northern Minnesota Sunday morning, with Embarrass registering a frosty 33 while International Falls logged a record-breaking 37. Since Friday, the highest temperature Chicago could muster was 72 -- great for mid-May, but rather chilly for mid-July.
In stark contrast, intense heat is baking the Southwest. Death Valley recorded its ninth straight day of 120-degree-plus temperatures Sunday with a high of 126. That California desert site hosts the nation's all-time record high of 134 established on July 10, 1913. Record highs also tumbled in Texas, with Corpus Christi at 98, Brownsville at 100 and McAllen at 106.
Readings will gradually warm into the 80s this week in Chicago, but the below-normal temperature trend is expected to continue and 90s aren't due anytime soon. Scattered showers and storms also will affect the city this week, with the most widespread and heaviest activity expected late week.
