There is a limited threat of severe storms tonight. Large hail to quarter size will be the main threat. Damaging winds to 65 mph are possible over southeast Oklahoma after midnight. Storms will increase in coverage tonight ahead of a cold front. For the most part, storms will be rooted above a stable boundary layer, limiting the threat to marginally severe hail.
Storms could get rooted closer to the surface as instability improves across far southeast Oklahoma after midnight tonight, increasing the damaging wind threat with any storms there as well. Rainfall coverage and amounts will increase tonight as storms increase.
Some locations could get around an inch before all is said and done, with isolated amounts up to 2 inches possible. As a result, there is a limited threat of flash flooding tonight.
