Weather in the absence of metar

Tell me, why the weather of the nearest airport is not loaded to the airport where there is no metar? Always loaded: 2992 pressure and temperature 15C, although the nearest airfield mettar is determined. Either shows LAND, but the pressure remains 2992 and the temperature is 15C.
For example: USRR, always 2992 and 15C, and the nearest USRR. Why doesn't the USRR load the weather? Thank you.
And so everywhere at small airports - not the nearest weather station, but simply always 2992 and 15C.

Hello
