The National Weather Service has issued a winter storm watch through Saturday night for southwestern Oklahoma, including Oklahoma City.
The weather service says up to 4 inches (10 centimeters) of snow, in addition to a thin layer of ice, could fall in the area.
Fallin's order issued Thursday allows state agencies to make emergency purchases related to disaster relief and preparedness. It is also a first step toward seeking federal assistance should it be necessary and waives licensing requirements for vehicles bringing in materials and supplies for storm relief.
The executive order will be in effect for 30 days.
