Narrative:

We have a low level windshear system at tulsa. It has sensors at north, ctrfield, southeast, southwest, west. As a major thunderstorm passed last we, we received many different windshear alerts. 4 of the 5 sensors reported windshear, and winds in excess of 30 KTS. The southwest sensor, which did not indicate windshear, never indicated more than 9 KTS. This has been reported in the past, and no action has been taken. I feel this affected safety at tulsa on X night.
