A meteorologist should respond to this question with their general workflow day-to-day when they come into the office and produce a forecast. They should mention all of the credible sources they use to figure out temperatures, and mention a variety of maps they use to see how the weather will be changing and what that means for the viewing area. They should mention sources from both local radars and national ones, so they show they have an understanding of how weather throughout the country affects the local weather and climate.
