Episode Narrative Repeated rounds of thunderstorms with heavy rain caused flash flooding in Sauk and Columbia counties. The thunderstorms developed ahead of a warm front, as a low-level jet pushed warm, moist air over the boundary. Surface temperatures in the low to mid 80's, along with moist dew points in the low 70's, contributed to the instability needed for the thunderstorms as well as provided ample moisture for the heavy rain. Precipitable water values were over 2 inches. National Weather Service Doppler radar estimated 5 to 6 inches of rain fell in extreme northwest Sauk County.
Event Narrative Several rounds of thunderstorms produced heavy rain that closed numerous roads in Caledonia Township, west of the Wisconsin River and southwest of the city of Portage. The rushing water damaged roadways and washed out gravel shoulders, as well as causing damage to private driveways.
