Heavy rainfall, thunderstorms, and gusty winds are expected across the Central Plains into the Mid Missouri Valley. Widespread precipitation and heavy mountain snow will continue across the Northwest. Severe thunderstorms are expected this afternoon and evening from parts of east Texas into Louisiana. Heavy rainfall is likely tonight across eastern Louisiana and southern Mississippi. Read More >
For the third consecutive week, after winter weather events on February 12, 2013 and February 20-21. 2013, a major winter storm affected the southern Plains with widespread snowfall on February 24-26, 2013. An upper level storm system dove southeast through the Great Basin into New Mexico, then intensified rapidly as it lifted east-northeast through West Texas and the Red River Valley.
Before any wintry precipitation fell, a few severe thunderstorms developed over southwest Oklahoma along a strong cold front. However, behind this front, very cold air allowed liquid precipitation to change over to snow and sleet by Sunday evening. The strength of this storm allowed it to produce significantly more wind than the ones which struck earlier in the month, leading to blizzard conditions in parts of northern and western Oklahoma.
A strong cold front pushed through the Texas and Oklahoma Panhandles on the afternoon and evening of February 24, reaching into far western Oklahoma by midnight. Heavy snowfall developed behind the front, then gradually spread eastward overnight as temperatures fell to near or below freezing across western and northern Oklahoma. By early afternoon on February 25, moderate to heavy snow was occurring over most areas northwest of a line from Hollis to Kingfisher. Very heavy snow bands and occasional thundersnow led to significant snow accumulations over a large part of northwest Oklahoma.
Several areas saw snowfall in excess of 15 inches, and when combined with the snow that was already present from the winter storm a few days before, snow depths of up to 25 inches were reported in localized areas. Strong and gusty winds led to snow drifts up to 5 to 8 feet in depth, shutting down many highways and secondary roads in western Oklahoma. The heavy wet nature of the snow caused some structural damage at Alva, Cherokee, and Woodward.
Widespread power outages were reported due to snow-covered power lines and downed trees and tree limbs. The rain-snow line hovered near the I-44 corridor and Oklahoma City metro area for much of the afternoon, with many areas to the east only changing to snow after sunset as the event was winding down. The snow gradually tapered off from west to east during the late afternoon and evening, with most of the accumulating snow in central Oklahoma ending by midnight.

The above radar animation shows the progression of the winter storm across the area beginning at 3 pm CST Sunday, February 24th, and running through 8 apm CST, February 26th. An area of thunderstorms initially developed over southwest Oklahoma on the evening of the 24th. These storms produced a few severe wind gusts up to 80 mph and small hail. This was quite unique in that some areas over southwest Oklahoma were within severe thunderstorm warnings and blizzard warnings at the same time. These storms were fueled by a strong cold front that surged southward during the overnight hours. Rain and storms quickly changed over to snow, sleet, and freezing rain over portions of northern and western Oklahoma, and even western north Texas. As frozen precipitation began this early in the event, it';s no wonder that these areas saw the greatest amount of snow. (Images courtesy of the Storm Prediction Center)

The above infrared satellite animation shows the progression of the winter storm across the area beginning at 6 pm CST Sunday, Feb 24, and running through 7 pm CST, Feb 26. IR satellite depicts cloud top temperatures. In this animation, blues indicate cold cloud tops, which are normally in the high levels of the atmosphere, and are often convective in nature. The reds, yellows, and greens indicated low to mid-level cloud tops. The cold cloud tops with this system were initially associated with thunderstorms over southwest Oklahoma and north Texas. these storms produced very heavy rainfall, hail, and even damaging winds. However, much of this transitioned to snow by the morning of February 25th. Note the cold cloud tops over northwest Oklahoma and the Texas panhandle halfway through the animation. These were associated with convective snow bands, which produced very heavy snowfall and, at times, thunder and lightning. Toward the end of the animation, cloud tops begin to warm, indicating most of the heavier snow had come to an end - one of the reasons much of central Oklahoma didn't see the heavy snows that were forecast.
As seen in the map below from the Oklahoma Mesonet, the strongest winds with this system occurred west of I-35, where gusts over 50 mph were recorded. Sustained winds ranged from 25 to 35 mph.
