Mesoscale Discussion 1062 NWS Storm Prediction Center Norman OK 0937 PM CDT Wed Jun 14 2023 Areas affected...Central Mississippi to west-central Alabama Concerning...Severe Thunderstorm Watch 301... Valid 150237Z - 150430Z The severe weather threat for Severe Thunderstorm Watch 301 continues. SUMMARY...Severe thunderstorms will advance across central Mississippi toward west-central Alabama late this evening. DISCUSSION...Low-level warm advection continues to be focused along the western fringe of the convectively overturned air mass over the central Gulf States. Latest VWP and short-term model data suggest increasing southwesterly 850mb flow across southern MS into southern AL tonight. This is in response to the short-wave trough currently located over southern MO/northern AR. Several long-lived supercells have progressed across AR into central MS and this activity is expected to propagate into western AL with time, aided by the upstream trough, deep westerly flow and warm advection. ..Darrow.. 06/15/2023 ...Please see www.spc.noaa.gov for graphic product...
