| A sounding,or Skew-T is information for the vertical atmospheric conditions at a point in time. Soundings start at the surface and go up several miles into the atmosphere. | A sounding,or Skew-T is information for the vertical atmospheric conditions at a point in time.

| Below is an example of a sounding. The magenta layer at the bottom represents the surface layer. This varies based on location, and can be higher or lower than what is presented. The peach color is the lower and mid-levels. These are the levels in which during winter matter the most, since they often dictate what precipitation falls. This includes the 925mb layer through the 850mb layer. Above that is the upper levels, and above the upper levels is the extreme upper levels layer. | Below is an example of a sounding.

| The temperature isotherms can be read through the red line and the degrees in C at the bottom of the chart. The isotherms are angled, so be sure to follow the temperature at the angle instead of vertically. An example of telling precipitation type is if the temperature line is completely to the left of the blue line, then the precipitation will be snow. If it is to the right of the line below 850mb, then it will be rain. | The temperature isotherms can be read through the red line and the degrees in C at the bottom of the chart.
