to continuing coverage of the devastating tornadoes that we have been following for the last few hours and really throughout the day here on msnbc. i want to bring in meteorologist michelle grossman who's been tracking these major weather events since yesterday. the overarching question is how the heck does this happen, michelle? it seems like every one of these events gets worse with more loss of life. >> yeah. you know, and i think that's going to be the bigger weather question. it's going to be the climate change, it's going to be the warming planet. but i think right now we have to focus on, you know, this is probably the deadliest tornado event for the month of december. it's certainly quite possibly and most likely, most definitely going to be the deadliest event in kentucky in history. and it will probably maybe be in the top five overall in our u.s. history. those are lists because you do not want to be on. those are things we're certainly going to look at and talk about and delve in deep over the next
