Loftan was saying that under those particular circustances on that particular day the dew point had to be 11 for snow to happen? This means, of course, that the temperature would have had to drop to 11°F for it to snow. I think Loftan's all wet. Snow isn't dew. The snow is forming up in the clouds where it's moister and cooler. You know you've reached the dew point if you get moisture on your car windows, frost if the dew point is lower than freezing.
How cold did it get that day you got the snow?

Snow is kind of like dew. Don't ice crystals need a "nucleus" on which to form, usually a dust particle or something? In that sense it is a bit like frost forming on a surface - just a very, very small surface. And Faldage is right about the temperature being different "up there" in the cloud. That's probably the temperature that counts for the initial formation of snow. I've certainly experienced snow when the ground temperature is above freezing. Obviously where the snow originated it was below freezing!

Well, maybe she's just a little unclear on the concept. The dew point is what the dew point is. It's a dependent variable. The independent variables are temperature and relative humidity. If the temperature reaches the dew point condensation will form on whatever there is to condense on. If the dew point is 11 then the tempearture has to reach 11 for dew (frost) to form. Now it may have gotten down to 11 up in the clouds or the relative humidty may have been higher up in the clouds (more likely) giving us a higher dew point up there. If you look at the chart you'll notice that dew point matches tempearture at 100% relative humidity.

What do you do on a dew-dew=dewy day? A sold drink collects moisture, and needs a coaster
under it. And at the lab, a succession of such days meant that the air compressor tanks would
have to have condensed water bled off.

A sold drink collects moisture
There you go. Sitting out on the front porch, tempearture a balmy 95°F and a mere 15% humidity. The glass holding your gin and tonic is at a brisk 40°F and the little beads of moisture dripping onto your beautiful sun dress.
