US Records for longest continuous stretch of days of 100% cloudcover (recorded, cities)

[Siberiaboy]

Does anyone know or can point to episodes in recent history of sunless cloudcover exceeding multiples of weeks? What are the maximums by various states, cities, or regions of the North America continent?

Central Connecticut is currently on its 7th day of 100% cloudcover.

Not sure that the particular statistic you're interested in is recorded.

Cold Bay, Alaska averages 304 days of clouds, so long stretches of no sun are the norm there.

Just about anywhere else in the Aleutians or coastal Alaska are good bets.

The longest cloudy days I’ve seen in New Jersey over the past 10 years was a week long. Not that common.. probably similar to CT.

In the US, cloudy day doesn't exactly mean 0 sun. Days with 20% sunshine (80%) clouds are also considered to be cloudy.

OK. I can tell you from years of experience that during most cloudy days in SE Alaska during spring, fall and winter that sun rays, or even an obscure, bright object in the sky, are never seen.

I recall sometime 1984-1986, late winter, getting the paper and sitting down to eat in my college cafeteria in Pittsburgh, PA and the headline (I think it was THE front page headline, but perhaps a sectional - Local? - headline) was something about 40 days of no Sun. I am searching the Pittsburgh Post-Gazette archives in hopes of locating that story. I recall it had a graphic of a calendar with cloud icons in the corner every, single, day in the stretch.

Not sure but that’s pretty common in parts of Washington state and Alaska.
