Leon, Oklahoma

Nearing 9 PM...a broken line of thunderstorms stretched across southern and central Oklahoma...from just south of Duncan...to Purcell...Shawnee...and Stroud. Much of the activity will produce cloud to ground lightning and brief heavy downpours. Isolated stronger storms...located near the southern end of the line...will produce around nickel size. The most likely area for hail is south central Oklahoma...between Duncan...Ardmore...and Pauls Valley. The thunderstorms were occurring along a very strong cold front that was moving quickly toward southeast Oklahoma and Clay County Texas. Temperatures were in the 60s ahead of the front...while temperatures had fallen to the 40s in central Oklahoma...and to near 32 degrees in northwest Oklahoma. Areas behind the front will experience brisk north winds...averaging 20 to 30 mph throughout the night. Wind gusts to around 45 mph will occur in western and central Oklahoma. At the same time...a strong upper level storm will approach from the west. Rain and embedded thunder will expand in coverage over western North Texas...up through western...central...and northern Oklahoma. As temperatures fall below freezing in northwest Oklahoma...there will be a brief period of mixed precipitation...including light freezing rain and sleet. Light freezing drizzle had already been reported in Harper County. As the upper level storm arrives... however...the precipitation will change to snow. This is expected north of a line from Cheyenne to Taloga and Alva by midnight. The snow line will then progress southeast overnight...with snow reaching Mangum...Clinton...and Enid by 4 am.
