Thunderstorm chances are expected to increase across Eastern Oklahoma and Northwest Arkansas today in response to increasing moisture interacting with a weak surface frontal boundary stalled over the region. A few of these storms could become strong to marginally severe this afternoon into the evening hours with strong winds of 50 to 60 mph possible. Additional showers and thunderstorms are forecast to move into the region overnight tonight as an area of low pressure begins to slowly push northeast into the region. Thunderstorm chances become likely through the first part of the upcoming week across much of the region as the area of low pressure continues to slowly make its way through the Southern Plains. A continued transport of moisture ahead of the low will allow for multiple rounds of heavy rainfall to be possible across Eastern Oklahoma and Northwest Arkansas. Widespread rainfall amounts in the 2 to 4 inch range are currently forecast for parts of the region with locally higher amounts possible. Additional thunderstorm chances will remain possible late in the week as another upper level disturbance looks to approach the region behind the exiting low pressure system.
