  "definition": "Lifted Index. A common measure of atmospheric instability. Its value is obtained by computing the temperature that air near the\nground would have if it were lifted to some higher level (around 18,000 feet, usually) and comparing that\ntemperature to the actual temperature at that level. Negative values indicate instability - the more negative, the\nmore unstable the air is, and the stronger the updrafts are likely to be with any developing thunderstorms.\nHowever there are no \"magic numbers\" or threshold LI values below which severe weather becomes imminent.",
