How much snow equal one inch of rain?
148103
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 0.10 inches of water up to 4 inches depending on crystal structure, wind speed, temperature, and other factors. The majority of U.S. snows fall with a water-to-snow ratio of between 0.04 and 0.10.

All of 2005? That's a lot of snow days, but here's the data from LaGuardia Airport, NYC in which measurable snowfall (defined as more than a trace) was reported.\n\nJanuary 2005 (6 days): 17th, 0.3 inches / 19th, 0.8 inches / 22nd, 10.0 inches / 23rd, 2.3 inches / 26th, 0.2 inches / 30th, 0.3 inches\n\nFebruary 2005 (5 days): 20th, 0.5 inches / 21st, 4.3 inches / 24th, 4.0 inches / 25th, 2.5 inches / 28th, 4.5 inches\n\nMarch 2005 (7 days): 1st, 2.6 inches / 2nd, 0.1 inches / 8th, 2.7 inches / 11th, 0.7 inches / 12th, 1.6 inches / 23rd, 1.1 inches / 24th, 0.2 inches\n\nDecember 2005 (4 days): 4th, 2.3 inches / 6th, 0.8 inches / 9th, 3.8 inches / 31st, 0.5 inches\n\nTotal days with measurable snow in NYC for 2005... 22 days out of 365

it's measured by inches on the ground. to calculate how much water it would be then 10 in of snow = 1 in of rain.

I searched the web a little bit and they all seem to repeat the same information - 50 inches of snow at some places, 15 foot drifts, etc. Evidently few people stuck a thermometer outside then.\n\nCentral Park did take readings though, and they  are as follows -\nmin/max temperatures (°F), precip inches:\n\nMarch 12: 8 /33  1.45\nMarch 13: 6/12   .00 \nMarch 14: 12/37   .02\n\nThose were all record minimums for the dates, but not particularly different than other records that time of year:\n\nhttp://www.erh.noaa.gov/okx/climate/almanacs/nycmar.htm\n\nI am not sure how relliable the precipitation amounts are with all the snow blowing around (still causes observers problems in 2006), but FWIW they reported a total of 21 inches of snow:\n\nhttp://www.erh.noaa.gov/okx/climate/records/biggestsnowstorms.html\n\nTheir largest snow amount occurred this past February.\n\nAmounts were obviously greater further N, and I am sure many places had temperatures well below 0.

Rule of thumb is 1cm of snow = 1mm of rain.  Or 10 times.  \n\nSo 2 inches of rain = approx 20 inches of snow.

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

I don't understand why you are only concerned about 1/4 inch of rain, but a good method for accurate measurements is collecting rain in a coffee can placed at a location with as few obstructions as possible and where little if any will bounce off the ground or other objects into the can. The diameter of these cans is normally about 3.9 inches.\n\nThe contents can then be poured into a tube of much smaller diameter - for example 1 inch. The amount in the smaller tube corresponds to that collected in the larger can as follows:\n\nLa = Sa (Sd/Ld)^2\n\nLd: diameter of coffee can\nLa: amount collected in coffee can (what we want)\nSd: diameter of tube\nSa: amount in tube\n\nI.e., the ratio of squares of the diameters provides the required conversion from the amount in the tube to that in the can.\n\nExample: Suppose the coffee can has a diameter of 3.92 inches and the small tube has a diameter of .95 inches. You collect an amount in the can that is very difficult to measure directly, but when you pour its contents into the tube, you find it is not that difficult to measure as 5.22 inches. Helps to have a clear tube with accurate markings, and for large amounts it may have to be emptied and filled several times (best to wipe any amount sticking on the inside when that is done). Anyway for this situation:\n\nLd = 3.92\nSd = .95\nSa = 5.22\n\nThus\n\nLa = (5.22)(.95/3.92)^2 = .307\n\nslightly greater than 1/4 inch :)\n\nNote that (Ld/Sd)^2 = 17.02, so pouring into the small tube increases the resolution of the measurement by a factor of about 17.\n\nThat is essentially what the Long-term gauge shown here does:\n\nhttp://www.robertwhite.com/cgi-local/shop.pl?type=item&item=longtermrg&categ=rw_rainfall&nav_bar=weather\n\nThe advantage of that being that the smaller tube inside is marked with the conversion factor already accounted for - the amount can be read directly in 1/100's of an inch.\n\nSo if you want to save some money, you can probably construct something very similar using a coffee can &/or funnel and some sort of smaller tube for it to go into. I have the gauge, and can say it is designed very well and is accurate. Measurements with it and the coffee can as described almost always agree within 2% and often are virtually identical.

It depends, approx.13" There are rainfalls from October to May. See the link.

It is snowing like crazy in Kansas City.  We might get as much as 8", I heard.

There are a lot of different types of snow, packed, dry, wet... so the exact weight of your snow would depend on that.\n\nTry picking a 1' x 1' square of snow, put it into a tupperware container and hop on a scale with it.  After weighing yourself with the snow, put it down and weigh yourself... take that difference and multiply it by 154.\n\nhave fun :-)

go to weather.com a type in ur city or town.\n                      OR\nlook at a weather chart\n                      OR\nGo outside and measure the snow with a ruler.

Snow forms when there is cold air (below freezing) and percipitation falls.  Snow is made out of ice crystals.  Sleet occurs when rain falls from warm air (above freezing) and passes through cold air (below freezing) on the way down, and freezes into ice pellets. (Note: If the air is warm (above freezing) and the objects on the ground are cold, the rain falls, then freezes onto the objects on the ground.  This is called freezing rain.)

i lived in anchorage last year and  about this time last year was about 6 inches \n its weird cause the sun comes out during the day time (what few hours of light there is) and melts it into a sheet of ice and then it gets coverd again by more snow i would say there was no more then 10 inches at a time last year 2005-2006\n&#92;\n&#92; right now in bagdad Iraq there isint any snow :)

Yes, it's snowing out. We have about 1/2 an inch here in Upper Michigan. We are suppose to get a snow storm tomorrow and it's suppose to get somewhat windy.  We usually get alot of snow up here in the north but I heard it might be a mild winter this year. Time to get the old snow shovels out.

Just one. It's called rain.... lots of it.
