CHICAGO (CBS) — For this NATO Summit weekend, get ready for sweltering temperatures that will feel more like mid-July than mid-May.

CBS 2 Meteorologist Mary Kay Kleist the temperatures will easily climb into the 80s on Friday, although a light lake breeze will cool down the lakefront later in the day. As of 11:20 a.m., it was 73 degrees at the Chicago lakefront and at Midway International Airport; Gary, Ind.; and Waukegan, and 74 degrees at O’Hare.

A strong ridge of high pressure is keeping significant clouds and rain well to the north over the Upper Peninsula of Michigan.

The high for the day will not exceed the upper 70s along the lakefront, with the water temperature now at 60 degrees, and the ridge of high pressure to the east pushing southeast winds over the lake.

A high of 78 is expected on the Chicago lakefront, 77 in Zion, and 80 in Gary. But in Joliet, the high will climb to 85, in Kankakee 86, and in Peru 87.

But that will all change on the weekend, when a warm front comes in and drives temperatures up to subtropical levels.

The high for Saturday is 86 degrees, and for Sunday 88. Some areas could even see 90 degrees.

For Monday, the high drops back to 70, for Tuesday 71, for Wednesday, 73, and for Thursday 78.
