At 10 PM, a cold front extended from near Blackwell to near Enid & Watonga to Putnam to near Cheyenne Oklahoma. The cold front will continue to move south overnight. The front is expected to extend from near Hollis and Hobart to near Yukon and Edmond to near Stillwater Oklahoma by midnight. Winds will shift to the north and northwest behind the front with wind speeds of 25 to 40 mph with gusts up to 55 mph possible. Temperatures will also rapidly drop 15 to 20 degrees in an hour or two after the frontal passage.
Thunderstorms were building southwestward along the cold front from Kansas into Kay County at 10 PM. These storms may become strong to severe before moving east out of the area. A dryline also extended from the front southward along a Watonga to near Hobart and Frederick Oklahoma to near Seymour Texas line at 10 PM. Winds will be from the south at 15 to 30 mph with occasional gusts to around 40 mph for locations east of the dryline this evening. West of the dryline, winds will range from the west and southwest at 10 to 20 mph with occasional gusts up to 30 mph possible. Humidities west of the dryline will recover very little this evening until the passage of the cold front brings slightly higher dewpoints to the area.
Showers and thunderstorms will remain possible overnight along the cold front into parts of central and southern Oklahoma, east of Interstate 35. If storms do develop, some could become severe. However, chances of additional storm development still remains low
