(WJBK) - During Wicked Weather Week, we take a look at the science behind the forecast. The radar the FOX 2 Weather Authority team relies on just got a major upgrade.

The new radar is called dual-polarization.

FOX 2's Derek Kevra explains the difference between the old and new radar, and why it helps determine exactly what type of precipitation is coming.

While it seems like a small detail, knowing exactly what type of precipitation is falling is actually really important for forecasting severe weather. Knowing the size of the precipitation is important, too.

For example, the old radar technology could detect hail but the size. Forecasters couldn't be sure if there was a lot of pea-sized hail, or a few golf ball-sized hail.

The new technology is also better at detecting tornados which can help give more accurate warnings to the public, especially during night.
