LI

The term 'LI' as it applies to the area of the weather can be defined as ' Lifted Index. A common measure of atmospheric instability. Its value is obtained by computing the temperature that air near the ground would have if it were lifted to some higher level (around 18,000 feet, usually) and comparing that temperature to the actual temperature at that level. Negative values indicate instability - the more negative, the more unstable the air is, and the stronger the updrafts are likely to be with any developing thunderstorms. However there are no 'magic numbers' or threshold LI values below which severe weather becomes imminent. '.
