Meteorologists rely on standardized, data-driven tools for forecasts. Weather service maps compile official, measured atmospheric data (like pressure, temperature, wind patterns) which is a professional tool for forecasting. Guesses, non-expert opinions, and personal observations are not reliable, formal tools for creating accurate weather forecasts.
