On clear chilly nights with no wind, the difference in temperatures can be impressive. Not only the difference between city and rural but even where a temperature sensor is located. For example, I have a vantage vue located about 20 ft. off the ground and the temperature is 54. About 30 feet away is a vantage pro sensor 6 ft. off the ground, which is what the NWS says is the correct height, and that reading is 51.
