Extreme Heat Through Friday

Overnight low temperatures will continue in the upper-80s to low-90s this week as afternoon high temperatures climb to 5 to 8 degrees above seasonal normals. Late-season heat can be very dangerous, as tourists are coming in from cooler climates and locals are exhausted from fighting the heat all summer. Stay hydrated and avoid caffeine and alcohol!
