Severe Weather - What You Need to Know  Click to begin Section 1
Module  In the effort to spread knowledge about severe weather,
the National Weather Service in Birmingham has put together 3
educational modules everyone should take the time to watch.  It
is suggested you watch them in order, as each module builds on
the previous, but it's not required.  In the first section, we
delve into the science of tornado and severe thunderstorm
forecasting and detection.  We answer the questions, "What is a
Tornado?" and "What is a Supercell?"  We also touch on how wind
shear and instability act together to produce severe weather. 
Finally, we go over some basic weather definitions with which
everyone should be familiar.  In Section 2, we dive into the
severe weather warning process.  What is the difference between
Storm Based Warnings and County Based Warnings?  What is a
Polygon?  If you have ever wondered the thought process by which
NWS forecasters issue warnings, this is the educational module
for you.  Click to b
