SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0747 PM CDT Mon Jul 01 2024 Valid 020100Z - 021200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN EASTERN NE TO FAR WESTERN IA... ...SUMMARY... Strong to severe thunderstorms should persist for a few more hours across a portion of eastern Nebraska into far western Iowa, before diminishing tonight. ...01Z Update... Most of the severe threat across the central and northern Great Plains has diminished and this trend should largely persist through the rest of evening. One exception, where a severe wind and brief tornado threat should persist, is across eastern NE into far western IA. A leading supercell over south-central NE has recently become absorbed into a mostly non-severe QLCS. This process may yield some short-term strengthening of the severe wind threat along the south side of the QLCS amid a 45-kt low-level jet per UEX VWP data. Further increase of the low-level jet through the evening will probably maintain a threat for strong to locally severe wind gusts despite the more hostile airmass for surface-based convection near and east of the MO River, per the 00Z OAX sounding. A lone high-based supercell in east-central WY may persist east-southeast along the surface front for a couple more hours, with some potential for an addition storm or two to form after dusk. Marginal severe hail and wind will remain possible. ..Grams.. 07/02/2024
