Hi, I’m Kelsey McEwen — Meteorologist & Science Communicator

I’m a Canadian meteorologist and science communicator who believes you shouldn’t need a degree in atmospheric science to understand what’s happening outside your window.

You may know me as the Chief Meteorologist on CTV Your Morning, where I deliver national weather forecasts and break down everything from major storms and extreme weather to the everyday atmospheric science affecting Canadians.

But there’s a lot more to weather than the forecast.

Why does humidity make 30°C feel so much worse? Why can one neighbourhood get hammered by a thunderstorm while another stays dry? What exactly is an atmospheric river? And are you really supposed to put that much salt on your driveway?

Those are the questions I love.

I take the weather terms, forecasts and science you hear every day and explain what they actually mean, why they happen, and why they matter to you — without losing the fascinating science behind them.

After more than 15 years forecasting weather on television, I’ve learned that people are incredibly curious about weather. They just don’t always have someone to ask.

So ask me.

No weather question is too basic, too weird or too random.

What You’ll Find Here

Weather explained
Straightforward answers to common weather questions, confusing terminology, forecasting myths and the science behind what’s happening in the atmosphere.

Storms & extreme weather
Thunderstorms, tornadoes, hurricanes, snowstorms, heat, wildfire weather and the atmospheric ingredients that make them happen, explained without the hype.

Everyday weather science
The surprising ways weather connects to your home, your body, your garden, your commute and the world around you.

Weather science for kids & families
Hands-on experiments, activities and explanations that turn everyday weather into an opportunity to get curious about science.

Behind the forecast
A look at what meteorologists actually do, how forecasts are made and what life looks like behind the scenes of Canadian national television.

I’m also a mom of three, which means plenty of my science communication gets tested on a very discerning focus group at home.

My goal is simple: to make weather science easier to understand without dumbing it down.

Because once you understand what the atmosphere is doing, checking the weather becomes a lot more interesting than looking at an icon on your phone.

Welcome. Look around, get curious, and if there’s something about the weather you’ve always wondered, ask.
