Overview

A historic outbreak of arctic air resulted in record breaking cold temperatures that lasted almost two weeks for some locations in the combined Texas and Oklahoma Panhandles. The cold air moved over the northeastern combined Panhandles as early as Feb 8th, and spread southwest through Feb 12th, engulfing most of the southern plains by Feb 13th. The frigid arctic air would put a strain on area power grids, resulting in rotating blackouts for some locations (this was much worse for other portions of Texas ). In addition, two storm systems interacted with the arctic air to produce several inches of snow, not only across the Panhandles but across most of the Great Plains, including almost the entire state of Texas and surrounding states. Amarillo ended up with 5.0" on Feb 14th, and 7.4" on Feb 16th. Periods of flurries and freezing fog also occurred mainly in the overnight and morning periods almost each day Feb 12th through Feb 18th.
