Tornado Season lasts from February to July, but Broken Arrow and Tulsa Excluding North Tulsa are rarely affected somehow. Aside from that, always be on guard in the event of a major storm. Check the Tornado safety page for more details.
Oklahoma Weather is very harsh on road conditions and road repairs are needed on an almost yearly basis here. Please be prepared to slow down or stop for road workers as fines double for accidents in work zones as specified by Oklahoma State Law.
