Keep your umbrella handy over the weekend. We have a marginal risk for isolated storms on Saturday. But there is an enhanced risk for strong to severe thunderstorms on Sunday. According to the National Weather Service, the main severe weather concern will be large hail and damaging winds. However, an isolated tornado can not be ruled out. In addition, rainfall amounts of 1 to 3 inches could bring the potential for localized flooding, especially across those areas that had heavy rains earlier in the week. Please monitor local weather reports.
