An excessive heat warning that was in effect for a full week in Douglas County has finally expired.

Heat and humidity prompted the National Weather Service in Topeka to issue the warning on Sunday. It was extended twice during the week when the hot weather didn’t let up.

Lawrence saw six straight days of temperatures at or over 100 degrees, and recorded its hottest day of the year thus far on Friday at 105 degrees. It’s a high temperature last seen three years ago in August 2007.

A front that rolled through the county Friday evening brought severe thunderstorms, effectively cooling temperatures into the 70s. Scattered storms kept the region cooler into Saturday afternoon when the temperature reached a high of 94.

Nighttime lows are expected to drop below 70 degrees next week, which should help end the brutal heat wave.
