Valid 310553Z - 310800Z The severe weather threat for Severe Thunderstorm Watch 575, 576 continues. SUMMARY...A wind-damage threat is expected to continue over the next few hours, developing southeastward into parts of central and eastern Arkansas. A new weather watch will be needed soon ahead of the existing watch. DISCUSSION...The latest high-resolution radar from Little Rock shows a well-developed bowing MCS near the Arkansas-Missouri state line. The MCS is being supported by a shortwave trough embedded in northwest mid-level flow, evident on water vapor imagery. The MCS will continue to move southeastward at 40 to 50 knots along the northeastward edge of a corridor of moderate to strong instability, where the RAP is estimating MLCAPE in the 2000 to 3000 J/kg range. In addition, surface dewpoints along the track of the MCS are in the mid to upper 70s F. The environment should support a wind-damage threat that will likely continue along the leading edge of the bowing line segment. The wind-damage threat is expected to develop into central and eastern Arkansas, and may also affect parts of northwest Mississippi later tonight. ...Broyles/Edwards.. 07/31/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6JWP6YRO85y-q6bmAsabN_9QSf83M0sxTYSip5cnqCuh1Z-Wy1FqXbob_yAaJOnAFGPNkDIrM= 9SFwbMOsgTzlvPcaqw$ for graphic product...
