Temperatures will gradually warm over the rest of the week with highs Friday likely getting into the 70s across much of southern WI, excluding the cooler air near the lake. Chance for strong storms late Thursday and through much of Friday. There will be chances for a few severe storms though risks seem somewhat limited at this time.
Strong storms will be possible particularly across southwest Wisconsin as remnant storms from Iowa push in Thursday night. Still lots of uncertainty on how strong storms could be as they push in, but the potential is there for a severe storm or two. Storms will weaken as they push northeast.
