Sea Level Pressure & Temperature -
The animation shows hourly sea level pressure and temperature data for March 1, 2002. A surface high-pressure system is located over
the Northern Plains and a surface low-pressure system is over Arizona. This pressure pattern results in upslope flow in eastern Colorado.
The temperature values clearly show below freezing temperatures through all of the Northern Plains and Colorado. This upslope flow,
cold temperatures and ample moisture resulted in six to nin inches of snow from Denver to Fort Collins.
