SPC Jun 8, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0220 AM CDT Wed Jun 08 2022 Valid 101200Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF ARKANSAS...LOUISIANA AND MISSISSIPPI... ...SUMMARY... Severe thunderstorms with an accompanying damaging wind risk appear possible across parts of Arkansas, Mississippi and Louisiana on Friday. ...Arkansas to the Central Gulf Coast Vicinity... An MCS associated with a compact midlevel shortwave impulse will be ongoing Friday morning across parts of southwest MO/northwest AR/northeast OK. This impulse is forecast to continue to migrating east/southeast across the lower MS/TN Valley vicinity through the afternoon and the Southeastern U.S. overnight. Enhanced mid/upper northwest flow will overspread the ArkLaMiss region during peak heating, with a 40-50 kt 700 mb flow indicated by most guidance. Ahead of the impulse and to the south of the eastward-advancing MCS, a very moist and unstable airmass will be in place. Vigorous thunderstorm development is expected and a potentially organized bowing MCS may develop and spread southeast across central/southern AR, northeast LA and northern/central MS. There is some uncertainty in the southward spatial extent of the severe threat, but intense wind gusts appear possible with any bowing MCS that develops within/near the Slight risk area on Friday. ..Leitman.. 06/08/2022 Read more CHECK UPDATE ZOOM GRAPHIC
