Thunderstorm chances become possible again this afternoon and continue overnight tonight across Eastern Oklahoma and Northwest Arkansas. Like yesterday, the greater chances are expected to be this afternoon into the evening hours with much of the convection weakening with the loss of daytime heating. Daytime heating combined with instability interacting with a weak surface frontal boundary could allow for some storms to become to strong to severe with strong winds of 50 to 60 mph. The greater severe potential looks to be across parts of Northeast and East Central Oklahoma as well as parts of Northwest Arkansas. Thunderstorm chances increase Sunday through the first half of next week across Eastern Oklahoma and Northwest Arkansas as a broad area of low pressure slowly pushes through the region. Multiple rounds of precipitation along with the potential for locally heavy rainfall will be possible through this time period. Additional thunderstorm chances remain possible through the end of the work week as the low pressure exits and a second upper level disturbance looks to push through the Plains in its wake.
