• Description:
  J. J. George (1960) developed an index, the K-index, as a measure of thunderstorm potential. This index considers the vertical temperature and moisture profile through use of the following equation: K = (850 mb. temperature- 500 mb. temperature) + (850 mb. dewpoint) - (700 mb. dewpoint depression) Although J. J. George developed this index for use primarily in thunderstorm forecasting, an attempt is made here to relate this index to summer precipitation of any type (including non-showery), trace or greater amounts. This study is for Wilkes-Barre, Scranton, PA, for the period June through September 1971.
