Remove °F from sensor data

I am attempting to adjust my thermostat based on outdoor temperature, but i cannot get the forecasted data to read because it is a string with °F added instead of just the number and i get this error

Executed: May 7, 2022, 6:00:00 AM
Error: In 'numeric_state': In 'numeric_state' condition: entity sensor.openweathermap_forecast_temperature state '°F' cannot be processed as a number

here is my automation. I wont know if there are any other errors because I cant get past step one
