In winter, skies this dark would mean it was going to snow for two, maybe three weeks without letting up. In summer, it just means a little bit of rain.
Or at least it does here. Winter and summer in State College both last a little too long — meaning spring and autumn are more like after-thoughts than anything else — but we’re relatively protected from a lot of bad weather, I guess because we’re in a valley. (I might know for certain why if I’d ever gotten those jobs for which I interviewed at AccuWeather.) We definitely haven’t been having the tornado-like storms (or actual tornadoes) they’ve apparently been having in neighboring states.
We’ve had rain. Schizophrenic skies, rumbling thunder, and lots of rain.
