The more data the better, especially in two ways - (1) initial conditions outside one's area of interest determine the eventual weather conditions within that area; for instance, storms and upper-level atmospheric waves over the Pacific Ocean will morph and interact with their surroundings and eventually become a driver of U.S. weather. Without information from the Pacific Ocean, you'd be hard pressed to make a forecast for the western U.S.; (2) global observations allow for a better understanding of climate, how climate changes, and what drives it, which all starts with observed data. You couldn't monitor, say, global warming or other climatic patterns and changes if all you had is a detailed history of conditions in Chicago (as an example).

If there is a 40% chance of rain on Monday, 50% on Tuesday, and 40% on Wednesday then math tells us that there is a 82% chance of rain over those 3 days. Lately I have seen percentages listed for each hour of the day. For example, a 60% chance of rain for 7, 8, 9, 10, and 11 in the morning. Does that mean there is a 99% chance of rain that morning?

RADAR stands for RAdio Detection And Ranging. It can detect anything that will reflect its radio pusles. It is used to monitor airspace around airports, locate and track satellites in space, monitor atmospheric water density for weather stations... Many very useful functions.
