I did not put record flooding because i havent lived in our neighborhood for a year. However around town, especially the east side, ive never seen flooding this bad. A line of thinderstorms stalled overhead after we got numerous pre-line storms. All started in the late afternoon and continued till midnight. Some of the preline storms produced tornadoes in the central OK. |
