 ====== Temperature ======
-The temperature can be read through the red line and the degrees in C at the bottom of the chart. If the temperature line is completely to the left of the blue line, then the precipitation will be snow.
+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.
 ===== Dew point =====
 The dew point can help to show whether hail will form, evaporative cooling will happen, or if the atmosphere is completely saturated. If the dew point in the upper levels is low during a severe weather event, this helps to create an environment for producing hail, given that the mid levels and lower levels are saturated or humid. If they are low in the mid or lower levels, but high in the upper levels, and precipitation forms, the precipitation will evaporate and cool the levels below it. This is known as evaporative cooling.
