Thunderstorms cause flash flooding in Madison streets Monday amid hot week

Thunderstorms cause flash flooding in Madison streets Monday amid hot week


Madison saw flash flooding at intersections and in streets across the city Monday following strong thunderstorms.

Gusty winds, hail, and heavy rainfall accompanied the storms, and caused 911 services to go to priority calls only. A flash flood warning for the city was in effect until 4:45 p.m. 

Before the Monday storms, the heat index was predicted to hit 95 in Madison, according to the National Weather Service. 

There will be periodic chances for storms Tuesday through Friday and then again on Sunday, with the most widespread storms during the afternoon and early evening hours.

To the south, the first triple-digit temperatures of the year could be seen from West Texas to the Nebraska Panhandle on Monday, shifting slightly east toward Wichita, Kansas, and Oklahoma City Tuesday and Wednesday, AccuWeather said.

Possible rain totals predicted were a tenth to a quarter of an inch, except higher amounts possible in any storms that may develop, the Weather Service said.

Chances for showers and storms are 30% overnight, mainly before 8 p.m., as the low falls to around 69, and 40% Tuesday, mainly after 7 a.m., with partly sunny skies, a high near 87 and light southeast winds increasing to 5 to 10 mph in the morning.
