Chance of a Thunderstorm?

I see ‘Chance of thunderstorms’ often. Although it depends on if it’s isolated or a cell, squall etc.

I think the singular makes sense when a band of thunderstorm activity will be moving through a region. In a forecast covering a longer period in which more than one such storm is likely to occur, the plural would be more appropriate.

I like “Chance of thunderstorm activity.”

Since you are limited on space I say just go with chance of thunderstorms. It might be regional. Like I say half an hour, but most of my friends in MI say half hour.

Neither is more correct so it is whatever you want. I like what @Austinlad wrote.

There’s always a chance of a thunderstorm. Why today, the sky was mostly blue with a few puffy white clouds here and there and still, it was raining. For who? For what?

I hate hate HATE weather forecasts! What the hell does “chance” of rain mean? Chance of rain when? How much of a chance of rain? Does it mean it will rain 60% of the time (which time) or that there is a 60% chance that it will rain at any time during the period for which there is a chance of rain? And how long will it rain?

Do us a favor. Put us out of our misery. Define your terms. Tell us what “chance” means. I mean, I could tell you there’s a chance of thunderstorms. Anyone can. The question is how much of a chance when? Stop waffling. Either be a forecaster or go down to the bar and have a beer.

“Chance of thunderstorms?” Feh!

Singular sounds better in my head. If you were to talk about snow, you would said “There’s a chance of snow,” so why not “chance of thunderstorm”?

“Chance of thunderstorms” sounds more natural to me, though it wouldn’t be correct in a situation with only one thunderstorm. It feels clunky to have “a” in there.

What about “Chance of thunderstorm”?

Singular without the a is odd.

I just realized one of my news stations uses t-storms. Possible sctrd t-storms.
