Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 PM CDT Tue Jun 04 2019 Valid 050100Z - 051200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER AND MID MS VALLEY AND NM/TX REGION... ...SUMMARY... Strong/severe thunderstorms will be noted this evening from southern Minnesota into southern Wisconsin. A few severe storms will also linger across southeast New Mexico and west Texas. ...Discussion... Complex, and seasonally weak, split large-scale pattern continues across the CONUS this evening. Remnants of Monday night MCS have progressed into southern MN where old MCV appears to be partly responsible for renewed, strong/severe convection. Leading edge of this activity has formed into a squall line and is propagating southeast into southwest WI. Latest diagnostic data suggests air mass downstream into southern WI will support organized isolated severe and 01z outlook will focus higher severe probs along a corridor from southern WI into southern MN as cold pool-driven outflow is surging into this region. Farther southwest, strong convection has once again developed over the mountains from northern Mexico into NM. This activity will spread into the southern High Plains over the next few hours as weak LLJ strengthens some near the NM/TX border. Even so, this activity should gradually weaken later this evening. ..Darrow.. 06/05/2019Read more
