Ask The Weatherman for August 8, 2013:

Question: What are some things that can be seen from a radar image?

Answer: This depends on the type of radar you are looking at. Velocity radar images are used to determine wind speeds and if the winds are turning as well. This will allow meteorologists to identify tornadic forming storms. We can also take note of possible damaging winds. Precipitation mode images allow us to determine how heavy the rainfall will be and also helps identify bow echo features which would tell us that damaging winds are very possible with the storm. These are just a few features that the weather radar can be used for.
