Storms will increase in coverage across south-central KS and north-central OK with time, with one or more clusters expected to track to the east or southeast across the region into the evening. Large hail to golfball size and locally damaging wind will be the main threats with the initial more discrete cells, transitioning to a more substantial damaging wind event with the storm clusters as they progress across the area. For portions of E OK, storm timing may line up with evening fireworks displays and could impact lots of people that are outdoors watching the displays. It will be very important to remain weather aware going into the evening.

Low storm chances remain through Sat afternoon, and then increase Sat late afternoon/evening through Sat night from a storm complex forecast to move through. The primary severe weather timing is Sat evening into early Sun morning with locally damaging wind the main threat and hail a secondary threat. In addition, a heavy rain threat exists into Sun morning.

Brief improvement in the hot and humid conditions is expected Sunday-Monday, but the heat will return in earnest by mid week. Be aware of signs of heat stress and take precautions with outdoor activities.
