|A new record of zero tornadoes were reported in Oklahoma for May 2005, the only time in recordest history that Oklahoma has been shut out for May! But on the 25th, this storm came close to tornadoing as it passed from Okmulgee to near Henryetta, OK. Below is a one minute .avi file of me chasing the storm.
The storm formed along an outflow boundary south of Tulsa. Visible satellite and Oklahoma Mesonet wind obs noted a small Low pressure swirl along the cloud line near Okmulgee, OK. Several storms formed quickly about 4pm, and a huge wall cloud developed on the backside of a storm and dropped southeast. Tornado Warnings were issued and a funnel was visible from the south.
I had good road options so I took a chance on driving into the developing circulation, though it never materialized.
I witnessed the surface inflow wind changing from S to SE then quickly to NW and W as a funnel passed me nearly overhead. Plenty of nickel to golfball-size hail too.
