Lingering moisture, combined with a weak upper level disturbance, will bring another day of isolated to scattered showers and thunderstorms. Any storm that develops today will have the potential to produce heavy rain, gusty winds, and small hail. Showers and thunderstorms will then generally diminish shortly after sunset tonight. High pressure will begin to approach the region on Sunday. This will bring slightly warmer conditions. Less thunderstorm activity is also expected for Sunday, although some weak instability could bring a few isolated thunderstorms during afternoon and evening hours.
