The Cold Air Invasion (12/15/2008)

By: Paul Howerton - Senior Meteorologist

An arctic cold front surged across the area Saturday, dropping temperatures as much as 25 degrees in one hour.

Strong south winds and some clouds kept temperatures from falling very far overnight. In fact, many locations saw rising temperatures after midnight. Temperatures at 4 AM Saturday were near or above the normal high for the day (see image 1). This changed abruptly as the arctic cold front moved across the area.

The following temperature maps show the progression of the cold air across the area during the day:

The front surged southeast across the area during the day. By afternoon, temperatures just ahead of the front in extreme southeast Kansas were about 20 to 25 degrees above the normal highs for the date. This changed abruptly as the front moved through. For example, Coffeyville dropped from 68 to 44 in one hour, and Parsons dropped from 67 to 42 in one hour.

The Cold air is expected to remain entrenched over the area throughout much of the week.
