Regional weather today is primarily determined by weather balloons. They
are sent from National Weather Service offices across the US every day at
5:00 am and 5:00 pm. They find the temperature, barometric pressure, and
wind data of the different regions throughout the world. This information
is then compiled into a report available to news and other weather
Now a $4.5 billion modernization effort is equipping the National Weather
Service with more powerful satellites, more sophisticated radar and new
automated ground observing systems, whose atmospheric information is more
precise than that of even two years ago.
All of this means that prediction of general weather for your area is
getting more and more sophisticated, and less likely to be wrong.
Eventually, it will be good enough to tell you almost certainly if it will
rain tomorrow or not.
