T3

The temperature (in degrees C) of the air approximately 1 km above the ground. Since this air is less affected by daytime warming and nighttime cooling, it's useful to look at to figure out how much the air mass is changing. In the example below, the T3 numbers indicate a peak in temperature at hour 12, just prior to the cold front passage, followed by rapid cooling. Temperatures below zero have 100 added to them, so a temperature of 90 corresponds to -10 C.
