By "weather", we should not only think about clouds, or rain, or whatever we are used to on our thick atmosphere planet.
Many landable planet could have high wind speeds, and even if atmospheric pressure is low, they could really affect ships while diving down, and storms could carry clouds of sand (or other small particles) which could impair our vision while diving down, influence stability of the thrusters, maybe add some hull damage due to colliding with those small particles at high speeds.
This would also lay the groundwork for thick atmospheric planets, for adding more advanced dynamic effects later.
Don't think of clouds or fog or rain yet, that requires wet planets, and all landable planets are either frozen dry, or cooked dry, in the end: They are dry. OTOH, there may be gases on some planets which are liquid at some temperatures, like "metallic rain" or "methane rain". But I think that's too complex as a first implementation: Such planets would be pretty devastating to the ship, SRV or suit anyways. And on such planets, we should have puddles or ponds of liquids already - which we don't have. So let's keep it "simple" as a start.
I really like the idea of such "weather effects" (sand storms, lightning, ...) would affect planetary missions - and I'd really prefer it to affect both approach by ship, SRV driving, and on-foot. It would be a really great addition to make exploring more challenging and varied. And if we could observe some of those effects from space (think like "huge sandstorm") we could plan our approach better and not just land somewhere more or less randomly.
Later, thick atmospheres would bring devastating storms of small rocks. really damaging your ship, creating scary sound effects of impacts, you get the idea.
BTW: If we'd get terrestrial landable planets at some point, I wouldn't mind if this "landing approach" would consist of just an auto-guided corridor down to a hangar, and we could visit and explore a small part of a city (I wonder if the bars would sell beer there

). It would make sense that it wouldn't be allowed to free-flight a densely populated planet and only allow auto-landing corridors.
Yeah, we get light breezes and small dust clouds, but the atmospheric pressure needed to support clouds, hence rain, snow and other weather effects is greater that the current crops of atmospheric planets have. Mind you we used to get some crater fogs in really deep craters in old Horizons way back....pity they mostly went away.
Well, Mars at least has a weather cycle of hiding the planet in a quite uniform, planet-wide cloud of sand storms on a regular basis. And it probably has snow falling at the poles on a regular basis, made of frozen carbon dioxide. So, low pressure atmospheres can support such weather effects.
