Pittsburgh (KDKA) —The most difficult season to predict the weather is winter, mainly due to snow.
When predicting rain, predict how much water will fall from the sky and how much it will fall.
When it comes to forecasting, it’s as easy as it gets.
Water covers most of our planet, so it’s pretty common. However, how water works is quite unusual.
It is one of the substances that expands when frozen. When it comes to snow forecasting, you need to spend some time on frozen, expanding water.
We know that water expands when it freezes, but we need to determine how much it expands. It is based on how water expands.
Water does not expand in the same way every time.
It expands into different shapes, and those different snowflake structures create different building blocks for accumulation on the ground.
The flat snowflake structure stacks well. In other words, more structures are needed to make a large accumulation.
The pointed snowflake structure stacks up, leaving a lot of airspace. This means less water is needed to store more water.
This means that we need to know how much water travels our way and how much snow it can turn into.
So what determines their shape? There are many factors, such as humidity and the path that snow follows from clouds, but the main factor is temperature.
As the temperature changes, the type of crystals produced changes.
Generally, the fluffier the snow, the more fluffy it is, and the warmer it is, the flatter it is.
Simply put, we are calculating the ratio of liquid to snow. It’s a fantasy phrase, “this amount of water is equal to this amount of snow,” and you have to do this every time it snows.
This is an example of snowfall earlier this season. The first image is a measuring cup of melted snow.
The second image is the amount of snow before the measuring cup melts.
That’s a pretty big difference.
The average liquid-to-snow ratio in Pittsburgh is 12: 1.
This means that 1 inch of water is equal to 12 inches of snow, but that’s just an average, and the proportions vary considerably from snowfall to snowfall.
Once you know the ratio, you need to determine if it’s warm enough to melt the ground when it comes in contact with snow.
How the Great Lakes and nearby mountains help or hurt the snowmaking process, and how much it melts.
