Heat index values will reach or exceed 105 for much of the region, and a Heat Advisory is in effect for areas roughly along and east of a line from Graham to Killeen. Remember to stay hydrated, take frequent breaks if working outdoors, and protect your pets by keeping them off the hot pavement and providing plenty of water.
