The potential for heavy snow at higher elevations in the western U.S. will continue for many spots through the weekend. In the meantime, the eastern half of the continental U.S. will transition to above normal temperatures ahead of a pair of cold fronts next week that will bring readings back to closer to normal as we approach Thanksgiving Day.

A strong cold front plowed through Oklahoma and north Texas on the February 10, 2012, dropping temperatures across the region into the teens and twenties. The frigid temperatures continued into the February 11th, as most areas did not make it above freezing on that day. Very dry air also followed the front, with surface dew point temperatures in the single digits. The several hours of below freezing temperatures allowed the ground temperatures to fall rapidly as well.
A transient storm system approached from the central Rocky Mountains, as south winds brought slightly warmer temperatures north into parts of Oklahoma. The temperatures warmed above freezing over parts of central and southern Oklahoma, as well as adjacent areas of north Texas, but remained in the 20s elsewhere.
Snowfall began over the Texas and Oklahoma panhandles, and quickly spread east into western Oklahoma. Saturation of the drier air occurred quickly near the Texas panhandle border. A band of moderate to heavy snow set up shop over parts of western Oklahoma, with snowfall rates approaching 1"/hour. This band did not move much during the first several hours, resulting in a quick 3 to 4 inches of snow to accumulate. But the area of snowfall was on the move, with any one area receiving light to moderate snowfall for about 3 to 4 hours.
The isolated areas of higher snowfall totals over west-central Oklahoma were not the norm, as a wide a larger area of 2 to 3 inches of accumulation was more representative. Timing of this event was almost ideal for areas of central Oklahoma. Whereas the snowfall occurred earlier in the day over western Oklahoma, resulting in several more accidents, the snowfall occurred during the mid to late evening hours over central Oklahoma. Automobile traffic was at a minimum during this period, which resulted in few accidents. Numerous accidents occurred on area roadways during the event. The event may have occurred at an ideal time, however. Had this occurred during the work week, this may have had a higher impact. What may have been worse was the freezing fog that occurred a day after the snow ended. As mentioned earlier, south winds were present during the entire snowfall event. The south winds brought relatively warm air over Oklahoma, which melted much of the snow. The skies cleared, the winds calmed, and abundant moisture near the surface resulted in widespread dense fog. What made matters much worse was the fact the the temperatures fell below freezing resulting in freezing fog. The freezing fog deposited a thin layer of ice on the roadways and elevated surfaces. The morning rush hour was treacherous, with many automobile accidents reported. Luckily no serious injuries occurred.
