which climat conditions are required to snow?

The temperature must drop below freezing up in the atmosphere,  where there is a concentration of water vapor. Typically this is caused when a warm front (full of water) rolls over a cold front -- the drop in temperature condenses the water high up and it drops to the ground as snow. But it can also happen when a cold front moves over a lake (ie. lake-effect snow). This is seen in a place like Buffalo.

I think because different parts of the country still have snow and ice, while others are in the real spring and summer...\nIt just depends on where you live...

Cold and snowy (supprisingly enough)

Take a look at this site.  You will need to specify dates and places\n\nhttp://www.weather.gov/climate/

Before it begins to snow, the system begins to cool the air down to ground level.  As this happens, moisture in the ground moves up into the weather system, and eventually mixes with the already cold water, ect within the cloud.  As the snow begins to fall, the temprature drops for a short period of time, and then stabilizes. \n\nThis stabilization happens so that the snow can continue to fall without turning into ice.  On average, winter snow will fall between 14 F and 30 F.  However, it is possible for snow to fall at lower tempratures, however you will see an increase in temprature to have snow fall.\n\nNot all snow falls, however, fall within that temprature range.  Area's such as alaska, greenland, siberia, ect, can have snow even when it is much much colder.  However, the general rule still applies:  snow fall equels an increase in temprature untill a stabilization point has been reached.\n\nSnow that falls within the normal range is usualy wet snow, ie it is snow that is mixed with a bit of melted snow (water vapor), thus causing it to be heavy snow.\n\nSnow that falls below the temprature range tends to be dry snow, ie, snow that has completely frozen over.\n\nDry snow can be a major problem as it doesn't allow for the stabilization to occure at a quick rate, instead, blizzards, huge snow storms, ect, can take effect before the storm system actually stabilizes.\n\nHope that made sens&#92;e

could be snow, could be +10 or +20 degrees, could be a little bit of rain.  One never knows in the spring time!

Depends where you are.  Here it will probably be really cold again.. minus 17 Celsius last year. Brrrrrrrr!

Yes,it is a fact that it is cold at the poles where it practically snows all the time,but in the US temperatures don't drop that low.\nPeople say that-"it is too cold to snow" , because in this case the temperature is too low(for our geographical positioning) to "hold" water in the air which prevents it from snowing.\nHope that my answer has been useful!

Before it snows the sky may be clear permitting ground heat to be lost by radiation cooling to outer space.  The temperature may drop well below freezing.  While it is snowing the "snow cloud" blocks radiation cooling and reflects heat back to the ground.  Snow forms when the cloud moisture drops to 32F and water gives up its latent heat while freezing which opposes a further temperature drop.

Mild winter with little precipitation in the form of\nsnow. Blustery cold days ahead in early January\nIce storm or two mid Feb. and a really big snow\nearly March.

The weather in the winter in Uk, is normally very cold, sometimes it snows in december... u will need to wrap up warm and wear coats, scarf and gloves...

Yes it cdan be too cold to snow. \n\nThe driest spot on the face of the earth is NOT the Atacama desert, it is the South Pole. From the reference here are figures of mm. of precipitable water vapor in the air measured in 1995:\n\nSouth Pole \nPercentile, Winter  & Summer \n\n25%, .19    .34\n50%, .25    .47\n75%, .32    .67\n\nAtacama\nPercentile, Winter & Summer\n\n25%, .68 1.1\n50%,  1.0 2.0\n75%,  1.6 3.7\n\nThe Atacama is so dry that there are some places in the Atacam where it has never been any measurable rain recorded, in over 100 years of measurements. Yet, the driest season in the Atacama still has considerably more precipitable water vapor in the air than the most humid season at the South Pole.  \n\nSo the answer is, yes it can be so cold that there is no moisture in the air, so it cannot snow.
