Chickasha, Oklahoma

Around 245 am...surface observations indicated the leading edge of a cold front was near an Atoka to Durant line. Behind the front...very strong northerly winds continued at 25 to 30 mph with gusts around 40 to 45 mph. Temperatures at or below freezing were noted north and west of an Altus to Medicine Park to Chickasha to Oklahoma City and Stillwater line. Temperatures several thousand feet above the surface have cooled enough that most of the precipitation across far western and northwest Oklahoma will fall as snow. However...parts of southwest...central and north central Oklahoma may experience a few more hours of mixed precipitation in the form of freezing rain and sleet. A large area of precipitation across the Texas Panhandle and western Oklahoma will continue to advance to the west through the overnight hours. Some of the snow across western and northern Oklahoma will be heavy with visibilities below 1/2 mile. Areas west of an Altus to Hobart to Watonga and Freedom line will likely receive between 1 to 2 inches of snow between 3 and 5 am.
