Valid 040602Z - 040800Z The severe weather threat for Severe Thunderstorm Watch 182 continues. SUMMARY...A wind-damage threat is expected to continue across parts of the lower to mid Missouri Valley tonight. A watch extension in area has been made for Cowley and Butler Counties in Kansas. However, the line is expected to become increasingly marginal over time, and new weather watch issuance is not expected to the east of WW 182. DISCUSSION...The latest hi-resolution radar from Hastings shows a large-scale bowing line segment across southeast Nebraska and north-central Kansas. This line of storms is located near a warm front, which extends east-southeastward into northern Missouri. From near and to the south of the front, surface dewpoints are in upper 50s and lower 60s F, with MLCAPE is in the 1000 to 1500 J/kg range. In addition, a shortwave trough is evident on water vapor imagery over central Kansas. Large-scale ascent associated with the shortwave and the instability will provide support for the ongoing linear MCS for a few more hours. Isolated damaging gusts will be possible along the leading edge of the MCS. However, as MLCIN strengthens across the central Plains and instability decreases, the wind-damage threat is expected to become more marginal with time. ..Broyles.. 05/04/2024 ...Please see www.spc.noaa.gov for graphic product...
