Locally heavy rainfall and flooding potential exists across northeast Oklahoma with storms that develop along and ahead of a cold front. The latest data suggests that areas north of I-44 stand the greatest potential for flash flooding, and a flash flood watch is in effect until 7 PM. Storms that develop along and ahead of the cold front this afternoon will have a limited severe hail and wind threat that may linger into the evening. This threat is greatest across northeast Oklahoma and far northwest Arkansas. An active and unsettled weather pattern is expected this week. Several rounds of showers and storms are expected. Each round will bring potential for locally heavy rainfall and a limited severe weather threat. Storm potential shifts down into southeast Oklahoma on Monday with the cold front. The front retreats back north Monday night into Tuesday, spreading another round of storms over much of the region. A weak back door front could bring some isolated storms midweek to northern and eastern areas and an upper level disturbance toward the end of next week will bring more storm potential. A ridge of high pressure aloft is expected to build over the region by next weekend, thereby ending this stretch of active weather.
