Why does the weather forecast only report the lowest temperature today and the highest temperature tomorrow?

Pay attention to the forecast period. It is estimated that what you see is "from tonight to tomorrow during the day" (from 20: 00 to 20: 00 the next day). In this case, the highest temperature today appears at 2 am, and the highest temperature tomorrow appears the next day 14. The forecast result is of course from the lowest today to the highest tomorrow. If you look at the weather forecast during the day, from 08: 00 to 08: 00 the next day, it should be the highest temperature today to the lowest temperature tomorrow.

On the radio, if it is broadcast after 14 pm, the forecast result he got from the meteorological station should be from 20: 00 that day to 20: 00 the next day, that is, "the lowest temperature today" (02: 00 the next day, although theoretically it should be "tomorrow"), and "the highest temperature tomorrow" will appear.

Also, I think the forecast results broadcast on the radio are just read by the announcer directly from the forecast results of the meteorological station. There must be many such statements that confuse you, but they are all wrong. You can't assume that they are all right. You should listen to the professional predictions.
