Event Summary  (Updated 6pm 12/22/2013)

A significant ice storm impacted a large portion of Oklahoma extending from the southwestern portions of the state eastward through much of east central and northeast Oklahoma.  The swath of accumulating ice also reached into extreme northwest portions of Arkansas.  The weather event began as a strong cold pushed into northeast Oklahoma during the overnight hours on December 19, 2013.  The post frontal air was cold, however, the depth of the cold temperatures remained very shallow, generally less than 1500 ft thick.  This forced the cold front to stall upon impacting the higher terrain of northwest Arkansas into southeast Oklahoma, with locations south of the front remaining much warmer than locations north of the boundary.   The location and magnitude of this cold front was a determining factor in the exact location of the heaviest icing and became a key feature during the forecast process. 

A broad region of unseasonably high moisture was located across the Southern Plains ahead of the strong cold front.  The upper air balloon launched from Fort Worth, TX Saturday morning (12/21/2013) sampled 1.32 inches of precipitable water.  This is a measure of the total moisture available, and this amount is in the top 5% of precipitable water values observed during December for Fort Worth.  This rich moisture was then lifted as a strong storm system tracked toward the region, with precipitation expanding into eastern Oklahoma Friday (12/20/2013) evening, and increasing in coverage and intensity Friday night through Saturday (12/21/2013).  The shallow, yet very cold, nature of the airmass north of the cold front allowed widespread freezing rain to develop, with a swath of heavy icing along the Interstate 44 corridor and also across a portion of Osage County.  Ice accumulations of 0.50-0.75 inches were reported in these areas.  Further south, across southeast Oklahoma into extreme northwest Arkansas, icing accumulations of 0.25-0.50 inches were reported.  The extensive icing extended west across much of Oklahoma, with the Oklahoma Mesonet reporting many frozen wind anemometers across the state.  South of the cold front, temperatures remained warm enough to prevent icing, however localized flooding was reported with the widespread and long duration rainfall.
