The extreme heat will even stretch as far north as Maine. In Caribou, Maine, where the temperature is forecast to hit 96 degrees, the National Weather Service issued its first-ever excessive heat warning. If it does reach 96 degrees in Caribou, it would tie a record for the hottest day ever in the month of June, a record that dates back to June 29, 1944.

The record heat will continue in the Northeast over the next few days, with Thursday forecast to be the hottest day along the Interstate 95 corridor.

The dome of high pressure that is causing all the record heat will then move back into the Ohio Vally by the end of the week and into the weekend. This will bring back the dangerous temperatures to cities like Chicago, which is forecast to reach 96 degrees on Saturday.
