Today's high in Knoxville got up to 96 degrees.

In 2010, we have had 41 days at 90 degrees or higher.

We had a warm low of 79 degrees on June 30th, 1936, but today's warm start "takes the cake," so to speak.

The chance of rain on Monday and Tuesday is running around 60 percent. A cold front will be stalling across East Tennessee, allowing for more rain to move into our area.
