Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0802 PM CDT Fri Jul 10 2020 Valid 110100Z - 111200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN SD INTO CENTRAL NE... ...SUMMARY... Severe thunderstorms will remain possible for much of tonight across portions of the northern and central Great Plains. Large hail and damaging wind are the primary threats. ...Northern/central Plains... Multiple supercell clusters ongoing at 01Z across the northern/central Plains are expected to persist for a few hours this evening, with a continued risk of large hail and damaging wind. The intense long-lived cluster moving into north-central KS should eventually weaken as it encounters an environment that has been stabilized by earlier widespread convection over southern KS and OK. Further north, in closer proximity to a midlevel shortwave trough, ongoing clusters will likely be longer lived as they move southeastward with time. Upscale growth into a larger MCS remains possible into central/eastern NE late tonight, though the southeastward extent of the severe threat into parts of eastern KS/western MO remains uncertain, due to the aforementioned stabilizing influence of earlier convection to the south. ...Southern New England... Deep convection is largely absent this evening in association with Tropical Storm Fay. While low-level flow/shear north and east of the center remains sufficient to support a conditional threat of a brief tornado or locally damaging wind gust, this threat will remain quite limited given the lack of deeper convection. ..Dean.. 07/11/2020Read more
