They will just lie about the reported temperatures to maintain the lie. They do now. In my area, the “official” reported low temperatures the past two mornings have been 36, and 34 degrees (they changed the 34 to 32 the day after)... the actual temperature has been 28, and 24 degrees (frozen bucket of water proves it, aside from the fact that my thermometers have been calibrated, but not recently, but all show the same temps within a degree or so). The temp right now is 37 degrees, but the “right now” temp on the internet says it’s 49 degrees. It’s like this every day, so the “official” temperature is inflated by nearly 10 degrees over the actual temperatures. This is one of the coldest Aprils I remember, but they will probably say it is in the top ten warmest.
"Good morning Jacksonville! It's a brisk 65 degrees on your morning drive, looking for high of 80 by late afternoon."
