The water vapor
image above (taken at 930 PM MST on February 16, 2003) shows moisture
content at approximately 30,000 feet above sea level. Light colors

The ( L ) over north central
Wyoming is the center of an upper level circulation or low pressure center
after it crossed the Continental Divide. The
blue arrow shows darker coloration indicating very dry air east of
the Wind River Mountains over Lander. This localized area of
very dry air indicates that the dry, heavier air from the stratosphere is
being pulled down into the lower levels of the atmosphere. The
yellow arrow shows the position of the main jet
