I’m wondering what other people’s dream weather is like…mine is always nice, like the temperature indoors (“room temperature”), it’s never hot, never cold, very comfortable. This would be ideal for me IRL as well so I’m wondering if that’s how my brain sets up my dreams. BTW, I’ve only had one LD, so this weather question personally applies to my ND s (if you can call any dream “normal”, LOL), I can’t say how my LD s will be but I hate winter so they’ll never be cold, I can tell you that! 
I have experienced bad weather in dreams, but i am always immune to the cold. In fact, weather from the wrong season is one of my best dreamsigns. The weather usually disappears when something interesting happens.
I bet that the fact do you feel cold, or warmth in dream depends on your room temperature where you are sleeping. I have had different seasons in my dreams. I have even runned in t-shirt in winter and had snow-storms, and camped in winter in ND-s, but i have felt cold only when i had my window open IRL and it was cold outside.
I have experienced both storms, freezing cold and nice weather. pretty realistic 
The temperature does not seem very linked with my room temp in my case.
I remembered a couple of dreams what i saw few months ago. In them i was in my childhood home, and i felt cold, so i perpared to make a fire in stove. But when i looked at thermometer it showed unusually high temperature. So i wondered why is it that. Unfortunately i did not became lucid. But i think that both times my bedroom was little colder than usual.
In my LD’s, it depends where I come from.
For example, if I jump or climb out my bedroom window (or even look out of it) it’ll be dark, with strong winds and maybe even rain.
However, when I climbed off my window sill and decide that maybe I’d actually rather go out the front door instead out of the window, it’ll suddenly be a bright day, with bright green glass and no wind or rain.
If the LD starts from just outside of my house, it can vary (though usually follows one of those two trends).
I have experienced a lot of tornados and lightning in dreams… However, generally the sky is pitch black, but everything is illuminated from some unkown light source!
So I can see - but without light - and it has never occurred to me to be odd (in my dream! - stupid dream self!!)
It’s usually nice weather for me in dreams. Either summer or snow, but it’s not too warm or too cold. And I rarely have bad weather in dreams. I rememeber a small tornado once, but that was because I was happening to dream about cds that containde weather sensors and the cds where sucked up into the tornado to get readings 
I’m pretty sure the temperature is connected to what my body feels IRL. And if there’s strong winds outside, I’m pretty sure I would dream about a storm or something.
Usually I don´t really have a weather.
Sometimes it´s sunny, but mostly it´s like the weather is just … absent.
Weather usually only appears if it has some importance to the “story” for me.
Has anyone seen any interesting atmospheric optics, like rainbows/ice halos/sun dogs etc? I have seen all three in normal dreams, but then I am quite interested in atmospheric optics but I don’t think most people are, I might be wrong. This is a really good website if you want to learn more, there are far more amazing and beautiful things to see in the sky than you would imagine!

Let me know if you see any of these in a ND/LD, I really want to see them in a LD one day, and would be very interested to hear people’s experiences of them in dreams.
I haven’t put much throught into the weather of dreams. However, as far as I know, all of my dreams have been sunny (though sometimes with a red/brown-colored overlay to it all) or there has been snow. I usually have those dreams in the summer, actually (though they’re rare anyway), but am never really cold. Once or twice I think I’m cold, but mostly it doesn’t affect me.
I havent noticed the weather in many of them. I think it’s usually calm. In RL I’m nearly always cold but I feel fine in my dreams.
Whatever the weather can be, I think I’ve dreamed it. The other night I had an LD with snow. Then I went outside and everything became like spring.
The weirdest “weather” I’ve dreamed of was the mooning coming down and drestroying earth. The exact same moon as in Majora’s Mask. Perhaps proof positive that I play too many video games!
it’s always nighttime
1984: Never seen any of them, but I have seen some unreal ones (like extra moons, or another galaxy hanging in the sky… tornadoes are cool, and so are UFO’s).
i’ve had all different kinds of weather in my dreams. Dreams with tornados can be real scary. i had one dream with where the tornado froze and i went over to tip it and it fell and broke.
Surreal: if you are interested at all check out my link. I found this site fairly randomly and got really interested, it’s a great site, probably the best for atmospheric optics, plus it might make your dream skies look more impressive.
