A weak cold front drifted south into Northeast Texas and Southwest Arkansas during the evening hours of November 3rd, ahead of a weak upper level disturbance that shifted southeast across the Middle Red River Basin of North Texas and Southern Oklahoma. Moderate instability developed along and ahead of the front due to an unusually warm and moist air mass in place, with near record temperatures observed on the 3rd.
