At 02:11:09 UTC (08:37:40 LTST, local daylight time) and 06:47:56 UTC (13:07:04 LTST, local daylight time), Mastcam Left filmed the inner rim of Gale crater, showing us obvious meteorological changes that occurred over a period of about four and a half hours.
During this Sol, the ground reached a maximum temperature of +5°C, although only three days earlier the maximum temperature reached +14°C!
A direct comparison of these two images, compared to the first photo, shows an increase in haze that has reduced the contrast and color saturation of the heights in the distance, as well as the appearance of a nice cloud on the horizon. In addition, the entire landscape appears slightly darker than in the morning photo, perhaps due to a thin cloud cover transiting in front of the Sun.
If so, it would also explain the lower maximum temperatures in the last two days (see REMS Mars Weather:
Certainly Martian meteorology is a bit more dynamic than one would be led to believe, with clear and (relatively) warm days as well as more cloudy and mild days.
