Post-frontal stratus deck caused recent cloudy skies, meteorologists say

Cloudy skies over the last few days were caused by a post-frontal stratus deck, meteorologists said.

Forecasters said this type of cloud layer commonly forms behind a cold front and can produce extended periods of overcast conditions.

Stratus clouds are a low, uniform cloud layer that often leads to gray skies, meteorologists said.

Observers on social media shared images illustrating the cloud deck in recent posts, according to those posts.
