The Winter Storm of February 11-12, 2013

Synopsis                                                                                                                               

After a relatively warm and dry January throughout the southern Plains, the first significant winter storm of 2013 affected the area beginning the evening of February 11. As a large upper-level storm system moved east out of the Rockies, precipitation developed over west Texas, expanding into parts of western Oklahoma overnight. By sunrise on Tuesday, February 12, moderate to heavy snow was falling roughly north and west of a line from Hollis to Clinton to Watonga, with widespread rain to the east. The rain-snow line progressed southeastward through the morning, with most areas north of I-44 in Oklahoma reporting snow by noon. Precipitation gradually tapered off from west to east during the afternoon and early evening.

The airmass in place for this winter storm was not particularly cold, and surface temperatures hovered near or just above freezing in most areas during the snowfall. This resulted in a heavy, wet snow. For many areas in central Oklahoma, including the Oklahoma City metropolitan area, roads remained wet and accumulations were mainly confined to grassy areas. In parts of west-central and northwest Oklahoma, temperatures right at freezing combined with very heavy snowfall rates for a few hours in the morning to allow for significant accumulations on all surfaces.

Snowfall totals were 1" or greater across most of northern and western Oklahoma, as well as parts of central Oklahoma northwest of I-44. Amounts greater than 4" occurred across parts of western Oklahoma, with the highest totals near the Texas border west of Elk City and Mangum.
