Elevated Fire Weather Threats for California; Cold Across Upper Midwest with Snow in Central Rockies

Unfortunately, elevated fire weather threats return this weekend for parts of California, as gusty offshore winds increase. Meanwhile, a large cold dome of surface high pressure will keep high temperatures 20 to 30 degrees below average across the Upper Midwest and down the High Plains. Also, heavy snowfall is expected from Wyoming into northeastern Colorado and western Nebraska. Read More >

Overview
The National Weather Service in Shreveport conducted a damage survey for Bossier Parish on Saturday, February 24th. The damage that occurred in Bossier City, LA, was the result of a very strong supercell thunderstorm that moved through the city during the morning hours.

The numbers of damaged structures was between 40 and 60 homes. The extent of damage ranged from a few shingles blown off some homes to substantial roof loss on other homes. Most of the homes that sustained damage had only roof shingles blown off. 

The damage path was located on the north side of Bossier City, north of Interstate 220, in the Hickory Ridge and Carriage Oaks subdivisions. The damage path was approximately one mile in length and 250 yards wide. The damage path ran parallel to Hickory Ridge Road and Lake Side Road, beginning near Coach Road, and ending near Coy Road in Bossier City.

The damage was consistent with that of a weak tornado on the Enhanced Fujita Scale. The rating for this tornado was an EF1, with peak wind speeds estimated at 90 to 100 mph. No injuries of fatalities were reported.

The Enhanced Fujita Scale is a new scale used to rate tornado intensity and was incorporated by the National Weather Service on February 1, 2007.
