When I looked at my usual weather site before walking the dog this morning, I knew the current temperature it showed was high. I then checked 3 other sites and got 3 different answers, with a 15 degree difference between the original and the lowest. The truth was probably somewhere between the middle numbers.

Probably all depends on proximity to nearest weather reporting station, location service settings (if using a phone), etc.
My observations when we lived in Marion County Florida was that inland north central Florida can have some dramatic temperature variances. I remember one time when a frost warning was up and going outside with my infrared temp tester and checking air temp at my compressor intake. No wonder the heat pump wasn't working, it was 19f! Frost warning, I'd say.

Many weather sites and news sites base their posted info on weather models and aged info, which means they're usually within 5-10 degrees of truth. What it is "right now" may have come from a reading taken an hour ago. Temps can also swing quite a bit from one location to another; if you're a mile from the place they get their data, you may be close to their numbers, and you may not be. They say all great comedy reflects real life. Remember George Carlin's spoof on TV weather reports? His character Al Sleet was a stoner ("the hippy-dippy weather man"), who said stuff like, "It's 72 degrees at the airport...which is stupid because I don't know anyone who lives at the airport." This is why many folks these days have an outside thermometer they can see from inside, or they have a remote sensor that transmits to a readout inside. One like this: www.amazon.com/ThermoPro-TP-60S-Hygrometer-Thermometer-Temperature/dp/B06XKH666P/ref=sr_1_9Mount the sensor at least four feet above the ground in a shaded location protected from rain. An ideal place is under the eave of your roof on the north side of the house, because the south side can receive reflected heat from the sun and give you warmer readings than ambient air temp. Don't worry about vented soffits because they are an air intake for the roof system. Change the batteries when you change clocks for daylight savings. |

That reminds me of when I was in college. I would wake up in my dorm room, turn on the radio, tune it to the college station, listen to see what the temperature was, and dress appropriately for the temperature. By the time I left the dorm I was 'way overdressed. And uncomfortably warm.
I suspect the student who was announcing on any given day would show up early in the morning, check the temperature, and report that all morning. And north Louisiana can have some wide variations from 5 am to 8 am.

Micro-climates.
Yes: depends on exactly where the readings were taken.
When I looked out the window at first light this morning, the house across the road and down one had quite a bit of ice on the roof, yet the one directly across the road had none. The sun hadn't hit either roof yet, so it wasn't that the ice had melted off the "iceless" roof: I think the icy roof is just more sheltered from wind/air movement during the night.
I know that when we get our occasional "hard" freezes, plants in certain parts of my yard are more prone to damage than plants in other parts.
The weather website I use for local weather has readings from different parts of town. During the summer, for example, the temperature always gets higher downtown, where there's a lot more pavement absorbing heat.

Altitude also effects temperature. Approximately -5.4F per 1000 Ft. My house is about 207Ft higher in elevation than the airport. So on an otherwise quiet day weather wise, the temp at my house will be about a degree cooler than reported by the airport. Lots of other factors to consider like wind, streets, driveways and parking lots. Houses, buildings, ponds, lakes and rivers all can affect temperature.

We have two channels we check.
One we call the cold channel.
