<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-size: 13.5pt; color: #454545;">Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

How big are hailstones?  That definitely can depend on where you live and how strong an updraft the storm has that produces them!

The best way to find out how large the hail might be that fell in your yard is to take an actual measurement.

Depending on what the diameter is in inches will determine the size.
