It's turned out to be one of the hottest days of the summer! The frontal boundary we've been watching has blown up across Kansas and Missouri this afternoon; however, the boundary's slowly moving south, so we're still expecting a chance for showers and storms this evening across NE OK and NW AR.

CAPE values this afternoon have climbed around 2,000 J/KG, which still suggests that the storms could produce small hail. Dry air aloft may also contribute to strong gusty winds around 50 mph.
