Here are the “official” high temps around town today. These are the NWS/FAA locations with ASOS sensors. They are all well-sited out in the open and away from “heat sources”. There is a common problem with home weather sensors (including mine with gets a bit too much morning sun). It’s really hard to measure temperature correctly and it’s very easy to get too hot of a temperature. You generally don’t get “too high” of a windspeed or “too much rain”, but temperature is a different creature. If your temperature was more than 2-3 degrees from these you probably have your thermometer in a warm place, or it just might read warm in general. Your sensors must be away from pavement, walls, roofs, decks etc…keep in mind that one of those objects/surfaces 20 feet “upwind” can give you the same effect. I see the “Rivergrove” on MADIS and “Liberal” were 112 and 108! Those are extreme examples. But I see one location in Washington County where two sensors read 97 & 98 and then another one nearby was 102.
One other thing to keep in mind; I notice most home weather sensors mention in the specs that the resolution could vary 1-2 degrees…another reason to always check yours against an official location near your home.
