Thunderstorms and Flash Flooding in Vermont
On this episode, Roger talks about Thunderstorms and Flash Flooding in Vermont
Early Snow Climatology, Snow Tires & Driving Skills
On this episode, Roger talks about snow climatology, snow tires, and driving skills
Astronomy- the Equinox, the Solstice & Seasonal Changes

Tropical Cyclones Part 3
On this episode, Roger Hill talks about the Green Mountain State’s history with tropical cyclones.
Tropical Cyclones Part 2
On this episode, Roger talks about hurricane seasons within the United States, and what causes them. Chart of frequency of Hurricanes based on date
Tropical Cyclones Part 1
On this episode, Roger talks about the Sapphire Simpson Scale, a way to categorize a storm based on its maximum sustained wind speeds. Anything ranked a category 3 or higher is considered a major hurricane.
A Time Machine Through Global Temperature Averages
Radio Vermont Forecaster Roger Hill looks at how temperature averages have changed since the end of the last ice age when compared to data from 1961-1990 and how the earth’s temperature affected early and modern humans. Then he looks forward, past 1990 to today and beyond. What does our temperature trend mean for the planet and humans in the next …
All About Wind
Wind is the movement of air that develops due to temperature differences in different parts of the world. The differences in temperature result in differences in density which results in differences in pressure. Wind results when these pressure differences try to normalize in an endless cycle of movement. Roger Hill explains the pressure gradient and what causes changes in wind …
Multiple Precipitation Types or Mixed Bag Precipitation
Roger details how varying air and ground temperatures at different levels of the atmosphere can produce interesting forms of precipitation such as sleet, hail, or freezing rain, or a combination of precipitation types. Ever hear a forecast call for a mixed bag precipitation? This is what they’re talking about.
Astronomical Equinox and Solstice
Roger talks about Equinox and Solstice, astronomic events that humans have observed for a very long time. Why don’t we see exactly 12 hours between sunrise and sunset during equinox? Roger talks about how latitude comes into the equation.
Clouds: Reading the Sky
This week Roger goes over the different types of clouds, where they usually sit in the atmosphere, and how forecasters can tell what’s going on in the atmosphere by looking at them.
Frost Quakes or Cryoseisms
Sometimes during Vermont winters, some seismic events occur called Frost Quakes or Cryoseisms. This occurs when a frozen ground, saturated with moisture, cracks with high intensity in a very localized areas. Roger explains in great detail how meteorological indicators can lead to these Frost Quakes.
How Do Snow Rollers Form?
Sometimes during the winter, the right temperatures and wind conditions come together after a snow fall and create snow rollers, curls of snow that can be hollow or bunched up like a cinnamon bun. We discuss this phenomenon in detail. Have you seen snow rollers? Let us know in the comments or on the WDEV Facebook page.
Inside the South Atlantic Magnetic Anomaly
Roger covers the Earth’s magnetic field and explores the South Atlantic Anomaly, a region over South America where the magnetic field is weakest that exposes satellites to high levels of radiation from space.
What Is A Computer Weather Model?
Often during a forecast, forecasters will talk about the various computer weather models and how they compare. What kind of skill is involved to interpret these and make a projection or forecast of what the weather will do? This podcasts gets into the science of weather models and also why the variables of the sophisticated analyses affects them so and …
