There is a risk of strong to severe storms as show by this SPC map for Thursday. For this particular case, there is a 30% risk of severe weather in Texoma within 25 miles of any point in this zone.
The most likely scenario will be for a squall line to form along a cold front moving in Thursday. Since there will be fairly strong low-level wind shear, an isolated tornado is also possible.
I still expect a dry and pleasant period Saturday into at least early next week.
