will the snow stick around?

We have seen several inches of snow here in Michiana over the past couple of weeks, and now with warmer temperatures in the forecast, people are wanting to know how long the snow will stick around. In order for us to make that determination we have to look at a few key factors that contribute to this process.

The first thing we look at is air temperature and wind. Temperatures need to be above 32 degrees to kickstart the melting process. This doesn’t mean once temperatures jump above 32 snow immediately starts to melt, it takes time. This is a topic we will cover later in this blog. Wind is important, because winds transport heat throughout our atmosphere. Here at the surface, if we have a few days with breezy winds, heat transports over our snow pack more efficiently, thus speeding the melting process.


Second, we look at two forms of radiation. The first form is shortwave radiation (solar radiation), which is produced by the sun. On days where skies are clear and there is no cloud cover we receive more solar radiation which helps melt more of our snow. Cloudy days do the opposite. The next form of radiation is longwave (earths radiation). The core of the earth is very warm, this warmth travels through the earth’s layers and is emitted at the surface. When there is lots of snow on the ground this radiation gets trapped. This is why air temperatures, especially during the night time, stay on the colder side when there is layer of snow on the ground. This then contributes to slowing the melting process.


Third, is the snow density. You hear us talk about wet snow vs dry snow with various systems that move through. Wet snow has more water content making it more dense, this means it needs more heat and energy to melt and then evaporate. Dry snow is less dense, therefore taking less time to melt and then evaporate.

Fourth, we reference the term albedo. You probably will never hear us throw this term out during our regular weather forecast, but it is important when talking about snow melt. Albedo is the measure of an objects reflectivity. The scale for albedo ranges from 0 to 100. Snow has a very high albedo at 99. What is the snow reflecting though? The snow reflects the shortwave radiation produced by the sun that we were just talking about. This naturally will hinder the melting process. This is also how you can catch a sun burn on a sunny winter day. If you are outside working or playing in the snow for a longer period of time, the suns radiation reflected off the snow will cause the sun burn to occur. 


Last but not least is latent heat. Latent heat is the most important factor that determines how long snow will stick around. Latent heat is the measure of energy needed to change the state of matter. For example, changing a solid to a liquid and a liquid to a vapor. To better explain this process think of pulling an ice cube out of the freezer. In the freezer temperatures are below freezing and the ice cube is a solid, now you pull the ice cube out and put it on the counter in a room that is roughly 70 degrees. That ice cube stays a solid, it doesn’t immediately turn to a liquid, this is because it takes time for the cube to gain heat energy enough to turn to a liquid. This is the latent heat process. When there is snow outside and it’s 40 degrees the snow doesn’t immediately melt, just like the ice cube.


So as we look at all these factors and the weather conditions in the forecast, we will likely see most of the snow on the ground melt by mid to late next week.

Frequently Asked Questions About how long does it take for snow to melt at 40 degrees

If you have questions that need to be answered about the topic how long does it take for snow to melt at 40 degrees, then this section may help you solve it.

Does 40 degrees F melt snow?

b>Temperatures need to be above 32 degrees to begin the melting process./b> However, once temperatures rise above 32, snow doesn’t start melting right away; it takes some time.

2 inches of snow should melt in how long?

2 to 4 inches of snow can melt in three days at 50 degrees; if nighttime lows are below freezing, the process will take longer. The amount of moisture in the air can speed up the melting process, while wind will carry the moisture away and protect the snow pack.

Will ice melt at 40 degrees?

An inch of rain falling in 40 degree air temps has enough thermal energy to melt about 1/16″ of ice. The wind that often accompanies rain accounts for most of the thickness loss of an ice sheet in a storm.

At 45 degrees, will snow melt?

Snow is a fancy-looking piece of ice that falls in small pieces but accumulates into a larger form when it settles. Since water changes states at 0°C or 32°F, and ice is the solid state of water, the snow will melt above 32° or freeze below 32°.

When does snow melt quickly?

Snow will melt day or night if the temperature is above 32 degrees; the warmer the air, the quicker the snow melts.

What accelerates snowmelt?

As temperatures rise above freezing, heat from the sun starts to melt the snow; the higher the angle, the more intense the sunlight, the faster it melts. While a number of factors can affect snow melting, air temperature and sun angle are the two main ones; the higher the sun angle, the better for melting.

What does 10 inches of snow melt down to in terms of water?

There is a general rule that states that 10 inches of snow equals 1 inch of water, but the truth is that it really depends on the temperature and the amount of moisture in the snow.

Ice on a driveway will melt at what temperature?

Without giving you flashbacks to your high school chemistry class, sodium chloride, commonly known as salt, lowers the freezing point of water, causing ice to melt back into water at 32 degrees Fahrenheit (0 degrees Celsius).

At 40 degrees, is frostbite possible?

In a wind chill of -40, frostbite can develop in less than 10 minutes.

Does rain aid in snow melting?

Other meteorological factors, such as wind and humidity, can also affect the snow melting process. Since snow contains many air pockets, melting can be accelerated when rain falls on these piles and gets into those air pockets. This action allows heat to penetrate these piles further, enhancing melting.

When does an inch of snow start to melt?

Every day is different, but as a general rule, we lose half an inch of snow per day in temperatures below 40 degrees, and between 50 and 60 degrees, we lose 2 to 4 inches!

Will the sun be able to melt the snow?

The sun can also still melt snow in extreme cold, according to meteorologists, because even though its rays aren’t doing much to warm the air, the snow is still absorbing the sun’s visible light and UV rays, which melts the snow.
