Two readings

It took me two readings to get the joke.


Meteorology professor: “How do we know it will rain tomorrow?”
Student: “The forecast says so.”
Prof: “But how does the forecast know?”
Student: “It examines radar readings and other inputted variables related to weather.”
Prof: “But how do we *know*, using those variables, we can predict it will rain tomorrow?”
Student: “Atmospheric volatility from pressure gradients, wind shear, convective energy, and jet stream interaction come together to produce higher or lower chances that water will condense around dust particles and fall as rain.”
Prof: “No, no, how do we KNOW it will rain?”
Student: *exasperated* “White privilege.”
Prof: “Yes, that’s right!”
