Heat Advisory in effect for all other areas outside of the warning. Stay hydrated and take frequent breaks if working outside.
Today and Wednesday will still be quite hot with highs in the mid to upper 90s and heat index values well above 100 F. However, a little relief may be coming for some spots later this week as chances of showers and storms increase starting Thursday.
