3:20 update:

Only minutes after we had checked temperatures at the airport, the National Weather Service extended the current excessive heat warning to Sunday evening at 7 p.m.

A reminder for anyone wanting to escape the heat this weekend: There are a number of public buildings in Douglas County that will be open for visitors to get a break from the high temperatures.

3:10 p.m.

It’s officially become the hottest day of the year in Lawrence, Kan.

As of just before 3 p.m., the mercury at the Lawrence Municipal Airport touched 103 degrees, the hottest temperature we’ve seen all year.

With the heat index, it feels like 108 degrees in Lawrence right now. That, fortunately, is not as hot as it’s felt. So, while it is the hottest day of the year, it may not quite feel like it.

Either way, though, we’re pretty sure it’s just plain hot.

Our earlier story:

The sidewalk sale has passed, but the heat has stuck around.

An excessive heat warning is in effect today and remains in effect through at least 7 p.m. on Saturday.

The high temperature forecasted for today is 101 degrees and it’s 102 degrees for tomorrow. Heat indices are expected to range from 103 to 110 degrees.

The National Weather Service and Douglas County’s Emergency Management Office reminds everyone to stay hydrated and avoid strenuous outdoor activity during the heat of the day.

There is a chance for thunderstorms in the forecast on Sunday, which may drop the temperatures a few degrees and move some of the humidity out by Monday and Tuesday.
