Why cant see the stars when its snowing/raining?

 

Thanks

Because the clouds are in the way.

In addition to John Cuthber's post, a large amount of raindrops/snowflakes would decrease the visual range too.

 

(But I have seen stars between the clouds during light rain-/snowfall.)

If the cloud is localized and not, itself obscuring said, Stellar object, the other cause of obscured stars is rain/precipitation. Rain will refract the light being emitted by the star. Take one specific "point" in time, imagine a molecule of water is directly in the path between the star, and your eye, the light is being refracted, different "colors" by different amounts, this will result in an image, your brain will not recognize as a star, if this occurs enough within a period of time, your brain will build up a picture that is very "blurry," (it will be hard to make out the stars,) the same effect will occur if you are using a telescope, or camera etc etc

 

and as for snow; Snow is NOT transparent, it also has regions of increased opacity (for light in the visible spectrum) due to increased/ decreased density.. this again will result in poor reception of light

 

this is a highly simplified version of what is occurring, with only a few effects mentioned.... I have given this as the primary post (above) is worded in a way that prompts a simplified response, if anyone would like a more accurate or descriptive answer, post below...
