Frigid Winter Weather At CASI HQ

January 11, 1999

Brutal winter weather continued at CASI HQ this week. Observed temperatures were in the single digits with snow. See CASI1 Weather Station capture from 8am and 8pm below. Notice on this PA Temperature Analysis that very warm air lurked just to the SW of HQ (center of PA) and that the gradient across one county was nearly 25 degrees. This type of warm air invasion at high elevations from the SW has accompanied nearly every storm in 1999 so far.
