Skew-T procedure to determine height of LFC

From the lifting condensation level (LCL) proceed upward along a saturation adiabat until you intersect the sounding temperature curve. The level of this intersection is the LFC.

In this example, the surface T = 9°C and Td=0°C, resulting in an LCL of 870 hPa and an LFC of 675 hPa.
