In this week’s episode of Weekly Weather Brief, meteorologists Emily Gracey and Kerrin Jeromin break down a historic winter storm that packed serious punch - including a jaw-dropping pressure drop of 41 millibars in just 24 hours. Was it a blizzard? A bomb cyclone? Both?

The conversation also shifts from snow to the tropics, highlighting how storms don’t stop evolving once they’re over. Drawing on analysis from the National Hurricane Center, they discuss how Hurricane Melissa’s winds were reassessed after the fact, and why post-storm analysis can sometimes upgrade a system’s strength.

Plus: lightning in snowstorms, the rare and electrifying phenomenon of thundersnow, and a look ahead at seasonal trends as winter begins loosening its grip.

Join Emily and Kerrin for the highlights, the science, and the stories behind the week’s biggest weather headlines!
