Update: St. Louis Now Enhanced Risk Wednesday as Missouri Storm Threat Expands — SevereWX

We've been tracking the clashing air masses priming Missouri for severe weather, first highlighted in our Tuesday outlook for Kansas City and St. Louis. The situation has evolved: the Storm Prediction Center (SPC) now issues an Enhanced Risk covering St. Louis, Missouri, on Wednesday, June 17, with Slight Risk areas expanding to Wichita, Kansas; Joplin, Springfield, and Kansas City, Missouri.

An Enhanced Risk signals scattered severe thunderstorms expected in and near the highlighted area—more numerous than isolated activity, with potential for significant impacts. Slight Risk means isolated severe storms are possible in those zones. Key hazards include damaging wind gusts over 60 mph, large hail (up to golf ball size or larger), and a lower but possible tornado threat, fueled by persistent Gulf moisture meeting frontal boundaries and upper-level energy.

This setup builds on yesterday's patterns, with storms potentially firing along lingering boundaries and shortwaves aloft. While not widespread like a Moderate or High Risk, the Enhanced area around St. Louis warrants close attention for metro impacts.

Stay vigilant: monitor your local National Weather Service office for watches and warnings, and ensure your severe weather plan is ready—know where to shelter and have multiple alert methods.
