ROANOKE, Va. (WFXR) — Are you a weather enthusiast? Love watching the skies? See if you can correctly guess this WFXR Weather Trivia question!

Fill in the blank: Thunderstorms are most frequent within ___________.

One of the key ingredients needed for thunderstorms to develop is moisture. Severe thunderstorms are more likely when the surface dewpoint is 55°F or higher.

Another ingredient for thunderstorm development is instability. Unstable air forms when warm, moist air at the surface rises into colder air higher in the atmosphere.

As the unstable moist air lifts higher into the atmosphere, a thunderstorm cloud can form.

Thunderstorms are most likely to develop in the spring and summer months, especially during the afternoon and evening hours. However, storms can occur year-round and at all hours of the day.
