It's Not the Heat, but the Humidity

Summer is in full effect and it feels very warm outdoors. Daytime temperatures continue to warm well into the 90s, but it feels warmer than that. That is because of the humidity, or moisture, that is in the air. I like to show the dew point values, which indicated at what temperature the air has to be at for 100% saturation. The chart to the left shows you the range of dew points that we see here in East Texas. During the summer, we typically see these values in the 70s, making it feel gross outside. You factor that in with the 90 degree temps, and that leads to heat index values over 100! I don't know about you, but I cannot wait for that first fall cold front. Is it October yet???
