Nowcast as of 11:00 PM CDT on April 3, 2011
At 11 PM, a strong cold front extended from near Ponca City and Perry to near Kingfisher and Clinton to Erick Oklahoma. Strong to severe storms had developed southwestward into parts of Kay and Noble County. 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 quickly drop 10 to 15 degrees in an hour or two after the frontal passage.

Thunderstorms may continue to build southwestward along the cold front into parts of central and southern Oklahoma overnight. Some of these storms may become severe producing large hail and strong straight-line winds. A dryline also extended from the front southward along a Hinton to near Hobart and Frederick Oklahoma to near Seymour Texas line at 11 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 and south of the front tonight. West of the dryline and south of the front, 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.

Also: Wind Advisory in effect until 1 PM CDT Monday
