About the heat index and wind chill
The heat index is how hot it really feels when humidity is combined with the air temperature. The National Weather Service uses these levels: 80–90 °F caution, 90–103 °F extreme caution, 103–124 °F danger and 125 °F or more extreme danger. At "danger" level, heat cramps and heat exhaustion are likely with prolonged activity outdoors — drink water often, rest in the shade or air conditioning and avoid strenuous work in the afternoon.
The wind chill is how cold it feels on exposed skin when wind is combined with cold air (it applies at 50 °F and below). At a wind chill of −18 °F frostbite can develop in 30 minutes, at −35 °F in 10 minutes: cover your skin, wear layers, a hat and gloves.
