Severe versus air mass thunderstorms

Storms that don’t rotate or have any way to vent rising air rarely last long

A couple of weeks ago we talked about what it takes to form severe thunderstorms: heat, humidity, lift, and some way to vent the air at the top of the storm. This week we’ll take a look at what it takes to make a severe thunderstorm and turn it into a thunderstorm that you just

Since they can’t get inside to measure, scientists aren’t completely sure how funnel clouds and tornadoes form

So far this month weather conditions have been fairly good for thunderstorms to develop with plenty of warm, humid air around. This week, we’ll continue our look at severe thunderstorms, and specifically, the most deadly part — tornadoes. What are tornadoes and how do they form?

Since they can’t actually get inside to measure it, scientists aren’t completely sure what causes a tornado

We’ve seen a few thunderstorms over southern and central Manitoba so far this July, but most have not been very severe. That said, over the weekend, southwestern Manitoba had a tornado watch in effect and that reminded me that we need to finish our look at severe thunderstorms and in particular, tornadoes. The biggest question
