Scattered severe storms are expected this evening from southwest through central and northeast Kansas.
Initial storms are expected to develop after 4pm to 5pm in southwest Kansas. This activity will spread northeastward into parts of central Kansas, potentially impacting Hays and Great Bend after 6pm. Storms will initially pose a risk for very large 2+ inch diameter hail, damaging winds of 60 to 70 mph, and possibly a couple of isolated tornadoes.
The storms will quickly cluster into a line as a cold front pushes eastward, which will lower the risk of tornadoes. Even after storms form into a line, the risk for damaging straight-line winds up to 70 mph will continue, along with the risk for large hail. While the tornado risk will be lower at this time, brief, weak tornadoes cannot be ruled out in the line throughout the evening.
The risk for severe storms will exit southwest Kansas and the Hays/Great Bend area by 9pm as the greatest severe risk shifts into central and parts of northeast Kansas, where the potential will continue for straight-line winds, hail, and possibly a brief isolated tornado.
The overall risk for severe weather will end by 11pm once the majority of the storms are in eastern Kansas and they begin to weaken. Locally heavy rainfall will remain a concern through the overnight hours for eastern Kansas as the storms continue to push east.
