We're tied for the warmest July (and month) on record in Portland. Today and tomorrow, we'll be running up the score.

A Heat Advisory has been issued for interior York, interior Cumberland, and southern Oxford counties. This is where the combination of heat and high humidity will make it feel like the mid to upper 90s.
