Bossier City, LA Weather

Bossier shares most aspects of its climate with its sister city of Shreveport. The city has a humid subtropical climate with hot, humid summers and mild winters. During the warmer months, the city is prone to severe thunderstorms which feature heavy rain, high winds, hail, and occasional tornadoes. The city has a slightly above average rate of tornadoes when compared to the US average. Due to the flat topography of the city and the prominence of smaller waterways that are prone to backwater flooding from the Red River, the city occasionally experiences severe flooding events. A notable occurrence of severe flooding occurred in March 2016 after torrential rains caused a rapid rise of many local waterways, displacing upwards of 3,500 people from their homes across the area. Freezing and ice storms occasionally occur during the winter months.
