Showers and thunderstorms are expected at times today through the holiday weekend with periodic chances for strong or severe storms. Starting late this afternoon into late this evening, scattered strong or severe storms capable of producing damaging winds, large hail, and isolated flash flooding are possible. The severe risk continues on Friday afternoon and evening, but there is uncertainty in where storms will develop. Additional strong or severe storms are possible on Saturday, but is dependent on the timing and placement of a low pressure system. Given the multiple days of potential severe weather, continue to stay up to date with the latest forecast and have multiple ways to receive warning information!
