Topic: US trip 2006 - 9th May tornadic supercells McAlister, Oklahoma

[Jimmy Deguara]

Hi,

We targetted the region just SE of Oklahoma City and basically headed from Kansas through to Ada in Oklahoma at the time of initiation:) A supercell developed explosively with CAPES of 5000 to 6500J/kg and moved towards McAlister. This storm became tornado warned with low level rotation. It had a large hook whilst in that area but it seems the tornado if one did occur was rainwrapped once again. It was surprising how quickly the supercells began to rotate.

We had some good rotation of the cloud base and wall cloud though. Lightning was, as anticipated, very frequent with any of the storms that developed into an MSC during the evening.

Further south of the border near McKinney, three tornadoes including one violent tornado struck during the late hours. Check the tornado damage pictures:
