Refer to the attached graphics.

Timing: This afternoon through this evening. The greatest risk is between 4 PM to 10 PM.

Impacts: Severe thunderstorms could produce damaging wind gusts bringing down trees and power lines resulting in power outages. Excessive rainfall rates could result in localized flash flooding, mainly limited to urban and poor drainage areas.

Confidence on occurrence: The risk for damaging winds occurring within our region is between 30 and 45%. The risk for flash flooding occurring within our region is 15 to 30%. The probability of a tornado occurring within our region is 2 to 5%. The probability of large hail occurring within our region is 5 to 10%.
