The watch includes almost all of eastern Oklahoma.
Thursday night, more showers and thunderstorms are likely, mainly before midnight, forecasters said.
More severe weather, including tornadoes, is possible later Wednesday with strong storms developing in mid-afternoon in western Oklahoma and moving north and east, according to the weather service.
On Thursday, we'll likely start the day off with showers and thunderstorms for the morning drive. Severe weather was slamming the Great Plains Tuesday and Wednesday, bringing hail and tornadoes with it. These storms cold produce some hail, damaging winds and even isolated tornadoes. A almost stationary frontal system will bring daily chances for strong to severe storms across the Central Plains through Wednesday. It's also only the fourth time in recorded history that Kansas has gone all of April without a tornado. For Wednesday, the entire area will be under a Moderate Risk. "Slight" is the second-lowest risk category and "marginal" is the lowest used by the SPC.
Numerous rounds of thunderstorms - some severe - are expected tonight into Thursday. A severe storm typically brings strong winds that can cause significant damage to structures and hail along with the chance for tornadoes to form. Some of these storms could be SEVERE. The weather service also reported 80 miles per hour winds and tennis ball-sized hail near Wymore, Gage County, according to Journal Star.
Area under thunderstorm watch early this morning
Sunday: 30 percent chance of showers and thunderstorms. Total rainfall through Saturday evening looks to be around a tenth to a quarter of an inch on average.
At the end of the day all the storm chasers we spoke with seemed to carry a consensus code with them on the road: keep your eyes peeled and stay caffeinated.
Tomorrow night: Mostly clear, cooler. Wind: S 15-25; gusty. Temperatures are expected to hit the low 70s for many, but the dry, sunny skies will make it feel summery. North wind 5 to 10 miles per hour.
Monday night: Partly cloudy; low of 48. Southwest wind 5 to 11 miles per hour. This warm air will put highs near 80 for a lot of the week. West wind 6 to 9 miles per hour.
