Is the weather forecast pressure at the location of weather station or at sea level?

The element forecast in the general weather forecast program does not predict the single station pressure. Maybe the weather forecast of some websites includes sea level pressure. If it's a local website, you can also forecast the pressure of the site after height correction. In view of the fact that the current weather forecast relies too much on numerical forecast, it is not surprising that the pressure forecast you see may be the direct output result of the numerical forecast model and has not been revised by the forecaster. In addition, you may not consider the change of air pressure with time. Generally, the air pressure rises in the morning and evening, and decreases after midnight and afternoon. With the movement of the air pressure system, the air pressure changes greatly due to the different positions affected by the air pressure system. For example, in the morning, it is just controlled by the high pressure center, and the air pressure may be higher. In the afternoon, the high pressure center has moved and the air pressure will drop.
