Have yous e'er seen it snowfall when it's above freezing temperatures outside?
Well, snow is ane of those fun weather phenomena that sometimes doesn't seem to follow Mother Nature's rules — much like these snow skiers (who are wearing shorts).
At What Temperature Does It Snow?
If y'all're wondering what temperature does it have to be to snowfall… the answer is 32 degrees Fahrenheit.
Information technology may seem illogical, but snow tin notwithstanding fall when it'due south above 32 degrees outside — and it actually happens fairly oft.
In that location is some pretty "cool" science behind this phenomenon.
And, every bit y'all'll run across, information technology'southward rather common for it to snow when it's 35 or xl degrees exterior — sometimes even warmer!
Here's everything you want to know about the temperature for snowfall to fall… and melt.
How Tin can It Snowfall Above 32 Degrees?
Meteorology (the study of weather condition) is a pretty complex science. But there's one affair that'southward common knowledge about water: information technology's got to exist 32 degrees for it to freeze.
So, how can information technology be that frozen precipitation such as snow flakes and flurries could fall when it's in a higher place 32 degrees at the basis level?
The Science Behind The Temperature For Snow
It's actually very simple….
- Yeah, it DOES have to be 32 degrees or colder for snow to grade .
- Just it DOES NOT have to be freezing at the surface for snow to hitting the ground.
More often than not, it is many degrees cooler in the levels of the temper where snowfall forms than information technology is at the ground level.
The air temperature decreases past about 5.vi degrees Fahrenheit every one,000 feet in distance through adiabatic cooling. So while it may be, say, forty degrees at ground level, it could be closer to 10 degrees just 5,000 feet up.
Snow tin can form as long as there's enough moisture in the temper where temperatures are at or below freezing.
Equally the snow falls through warmer segments of the atmosphere, it begins melting into rain.
At What Temperature Does Snow Melt?
If the air temperature is in a higher place 32°F, snow and ice volition start to cook. At or below 32°, it will remain frozen.

Snow tin really survive a descent of ane,000 to 2,000 anxiety before melting.
And so, if the air mass in the upper levels is colder than 33 degrees and just a very thin layer correct at the basis is above freezing, it's possible for snow to accomplish the ground — even when surface temperatures are in the high 30s or 40s!
However, if snow hits the ground when surface temperature readings are in the 40s (or higher), then the snow volition begin melting about immediately upon affect.
That ways there certainly won't exist much – if any – snow accumulation when it's 40 degrees. So, that's not going to give y'all much of a chance to make snowmen or have a proper snowball fight with your friends!
What's The Highest Temperature For Snowfall?
Snowfall was in one case recorded in Jacksonville, Florida at 53 degrees!
The best hazard of seeing a 50 F temperature and snow is when the air is dry out and the snow is adequately heavy. This will only last briefly though. The temperature will rapidly absurd off and the snowfall may change to rain.

Where Can Information technology Snow When It's Higher up Freezing Outside?
It'southward possible for snow to fall anywhere when information technology's above freezing temperatures outside, as long as all 3 of these conditions are met:
- It must exist moist plenty.
- It must existfreezing in the right levels of the atmosphere.
- That layer of higher up-freezing temperatures must exist very thin and close to the ground.
Conditions like that are nearly often found in these locations:
- Areas near water – Bodies of h2o can help moderate nearby surface temperatures. While the shoreline might exist in the high 30s, the temperatures just a thousand anxiety upwards may be at or well below 32 degrees.
- Large cities – Dense urban areas create so-called heat islands. Those are places where cobblestone, concrete, and other manmade materials absorb rather than reflect heat and create a thin layer of ambient warmth very shut to the surface. So, while it may be 40 or 45 degrees at the street level in a large city, information technology might be 30 degrees just one,500 feet up – a scenario in which it could snow above freezing.
- Other localized pockets of warmth – There are any number of other situations where the layer of higher up-freezing surface temperatures may exist very thin yet temperatures a few hundred anxiety upward are below 32 degrees. These include areas in the firsthand vicinity of factories, mines, and caves.
More than Cool Facts Nearly Snowfall
Okay, and so science explains how information technology tin can snow above 32 degrees.
But what else is at that place to know about snow?
Heaps! Hither are 10 more than cool facts about snow that volition blow yous away:
- On average, at least 1 septillion (trillion trillion!) snowflakes and other particles of icy precipitation fall in a given winter.
- The well-nigh snowfall recorded in a 24-hour period in the United States was in 1921, when 75.eight inches fell in Silvery Lake, Colorado.
- An amazing 63 inches of snow fell on December iv, 1913 in Georgetown, Colorado — creating the record for the well-nigh snowfall on a single calendar day.
- For a snowstorm to be officially categorized as a blizzard, winds must be at least 35 miles per hour and snowfall must be heavy plenty to reduce visibility to no more than a quarter mile for at to the lowest degree iii hours.
- In add-on to snowflakes, other forms of snow include graupel and sleet.
- Snow is not white. Information technology'south translucent (or see-through). It most often appears white because snowflakes have a plethora of tiny surfaces that scatter white low-cal — depending on the depth of the snow, the management of the sunlight, and the presence of shadows.
- It's said that all snowflakes are unique. Merely one scientist found 2 identical snowflakes in 1988 from a Wisconsin snowstorm.
- The largest snowflake on record was 15 inches wide and savage in Montana in 1887. However, the claim was never corroborated.
- Yes, information technology does snowfall in Florida! In improver to the Jacksonville snowfall mentioned in a higher place, it has snowed every bit far s equally Miami – a place that saw the white stuff fall from the sky in 1977.
- Only there's no snow in Key West, Florida. That's one of the few places in the United States snow has never been reported.
I'm a weather geek from Florida who's been studying meteorology and watching weather patterns for years! I savor sharing footling-known facts and fun stuff about the weather. I peculiarly like sharing interesting details about weather events and conditions that can touch y'all… and how to prepare for Female parent Nature's ever-changing weather patterns.
