Total nighttime snow accumulation of less than a half inch possible. Tuesday Forecast:. Local Weather Radar Here. Friday, November 12, Rutherford Source. Thursday Night: A 20 percent chance of snow showers before midnight. Cloudy, with a low around Most natural materials absorb some sunlight which gives them their color.
Snow, however, reflects most of the sunlight. The complex structure of snow crystals results in countless tiny surfaces from which visible light is efficiently reflected. What little sunlight is absorbed by snow is absorbed uniformly over the wavelengths of visible light thus giving snow its white appearance. Generally, snow and ice present us with a uniformly white face. This is because most all of the visible light striking the snow or ice surface is reflected back without any particular preference for a single color within the visible spectrum.
The situation is different for that portion of the light which is not reflected but penetrates or is transmitted into the snow. As this light travels into the snow or ice, the ice grains scatter a large amount of light.
If the light is to travel over any distance it must survive many such scattering events, that is it must keep scattering and not be absorbed. The observer sees the light coming back from the near surface layers mm to cm after it has been scattered or bounced off other snow grains only a few times and it still appears white.
However, the absorption is preferential. More red light is absorbed compared to blue. Not much more, but enough that over a considerable distance, say a meter or more, photons emerging from the snow layer tend to be made up of more blue light than red light. Typical examples are poking a hole in the snow and looking down into the hole to see blue light or the blue color associated with the depths of crevasses in glaciers.
In each case the blue light is the product of a relatively long travel path through the snow or ice. So the spectral selection is related to absorption, and not reflection as is sometimes thought. In simplest of terms, think of the ice or snow layer as a filter. If it is only a centimeter thick, all the light makes it through, but if it is a meter thick, mostly blue light makes it through.

Colors of snow, frozen waterfalls, and icebergs. No, it can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. Snow forms when the atmospheric temperature is at or below freezing 0 Celsius or 32 Fahrenheit and there is a minimum amount of moisture in the air.
If the ground temperature is at or below freezing, of course the snow will reach the ground. However, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right. In this case, snowflakes will begin to melt as they reach this warmer temperature layer; the melting creates evaporative cooling which cools the air immediately around the snow flake.
This cooling retards melting. As a general rule, though, snow will not form if the groud temperature is 5 degrees Celsius 41 deg Fahrenheit. For a more detailed answer, see When is it too warm to snow? Snow forms in the atmosphere, not at the surface. So snow can fall when surface temperatures are above freezing as long as atmospheric temperatures are below freezing and the air contains a minimum moisture level the exact level varies according to temperature.
Studies in the Rocky Mountains have shown that the fluffiest, lowest density 0. At colder temperatures, the crystal structure and size change. The water content of snow is more variable than most people realize. While many snows that fall at temperatures close to 32oF and snows accompanied by strong winds do contain approximately one inch of water per ten inches of snowfall, the ratio is not generally accurate.
Ten inches of fresh snow can contain as little as 0. The majority of U. Fresh, undisturbed snow is composed of a high percentage of air trapped among the lattice structure of the accumulated snow crystals. Since the air can barely move, heat transfer is greatly reduced. Please advise on next steps and timing.
Valerie Jackson. November 10, - am. How much snow will DC and Maryland will get this winter. Also, how cold and when do we expect the first snowfall? November 9, - pm. November 7, - pm. November 2, - pm. Will you please advise me of the probable weather for the Houston area this year? Last year we had a very nasty freeze that killed every one of my eight citrus trees one was 15 years old and the rest were about 10 years old , my two First Love gardenias eight years old , three green hedge-type shrubs five years old , my Monrovia Firecracker plant, my gorgeous Monrovia Double Peach Hibiscus that was covered with a heavy blanket , and my yummy Petite Negra Fig tree three years old , among other things.
Of all the plants, I am still upset about losing all my citrus trees especially my Variegated Satsuma because after 15 years it was starting to give me a decent crop and my Hibiscus because I LOVED that plant! And the fig tree, too! Besides the work involved in having to re-plant new ones I'm 72 years old and not in the best of health but can't afford to pay someone to do it for me , it's going to cost me an arm and a leg to replace everything.
Houston will be a bit wet, but mostly dry during Winter, expect most of the precip. Forecast may change, this is just a prediction. Olympia McFall. November 1, - am. We always check out the weather predictions first, then information on planting. Now the biggest attractions for me are all the newsy articles; amazing what I have learned. Best investment I can make every year.
