How to predict the weather if you know the pressure value?

1 standard atmospheric pressure = 10 1 325 Pascal, which is currently 1003 hectopascals, slightly higher than the standard atmospheric pressure. This alone is not enough. We should refer to the comprehensive analysis of temperature, humidity and atmospheric movement.

Current temperature; Humidity; 38.2°C； They are; 40%; -High temperature and dry air indicate subtropical high pressure control. If the subtropical high is strong, this weather will continue for some time. This is a typical dry weather in summer.

I hope it helps you.
