cloud up

I expected the temperature to stay in the 90s as I headed east, but instead the skies clouded up and the temperature began dropping, down to the low 80s.

“I’m about to cloud up and rain on you.”

“It’s like we are in the clouds up there,” snowboarder Jovanni Orozco told Albuquerque TV station KOB.

The sky had been clouding up all morning, but I was ignoring all signs of rain.

In its hourly report on conditions aloft, the National Weather Service described most of our daylight hours as characterized by a few clouds up there.
