Rain item is showing "1h" in the case when data are received from weather stations directly.
The fact is that some METAR stations do not have precipitation indicators or do not measure precipitation conditions due to some other technical reasons.
In this case, we use model data. So, rain item is showing "3h" when our system returns an API response based on model data.

Min/max temperature in current weather API and forecast API

Please, do not confuse min/max parameters in current weather API and forecast API. In current weather API temp_min and temp_max are optional parameters mean min / max temperature in the city at the current moment to see deviation from current temp just for your reference. For large cities and megalopolises geographically expanded it might be applicable. In most cases both temp_min and temp_max parameters have the same volume as 'temp'. Please, use temp_min and temp_max parameters in current weather API optionally.

Example of current weather API response:
"main":{
"temp":306.15, //current temperature
"pressure":1013,
"humidity":44,
"temp_min":306, //min current temperature in the city
"temp_max":306 //max current temperature in the city
},
For comparison look at example of daily forecast weather API response:
"dt":1406080800,
"temp":{
        "day":297.77,  //daily averaged temperature
        "min":293.52, //daily min temperature
        "max":297.77, //daily max temperature
        "night":293.52, //night temperature
        "eve":297.77, //evening temperature
        "morn":297.77}, //morning temperature
