A few strong to severe storms with locally strong to damaging wind gusts will be possible from a portion of the Northeast States into the Ohio and middle Mississippi Valleys Friday. ...Northeast States through Ohio and middle Mississippi Valleys... The upper pattern will remain characterized by a broad synoptic trough centered over the Great Lakes region. By 12Z Friday a cold front should extend from the lower Great Lakes through northern or central IL then westward into KS. A moist boundary layer will reside in the pre-frontal warm sector from the Northeast States into the OH Valley. However, there will likely be areas of ongoing thunderstorms and widespread clouds over portions of this region. Moreover, there is considerable uncertainty where the outflow boundaries and MCVs associated any ongoing activity will situated. Nevertheless, the atmosphere should become moderately unstable where diabatic heating does occur. Additional thunderstorms will redevelop along residual outflow boundaries, lake breezes as well as along the cold front. Vertical shear in the warm sector will remain weak and supportive of multicells, but storms may evolve into lines and clusters and become capable of producing isolated strong to severe gusts from afternoon into the early evening. ..Dial.. 08/11/2021 Read more LIVE: spc.noaa.gov
