Valid 150430Z - 150500Z The severe weather threat for Tornado Watch 45, 46 continues. SUMMARY...The severe threat across southern Arkansas and the Ark-La-Tex is expected to continue to decrease over the next hour, and the ongoing watches will be allowed to expire at 05Z. DISCUSSION...An MCS is currently located from far northeast Texas extending east-northeastward across western and central Arkansas. The RAP suggests that instability has markedly decreased along the southern edge of the MCS over the last hour. This trend will continue, and the severe threat is expected to gradually diminish. For this reason, the ongoing watches will be allowed to expire at 05Z. It still remains possible that the severe threat could re-develop across parts of the region, but this would be later tonight. ..Broyles.. 03/15/2024 ...Please see www.spc.noaa.gov for graphic product...
