Severe thunderstorms are not currently forecast for Tuesday. However, a few strong storms cannot be ruled out from northeast Ohio into western New York from late afternoon through evening. ...Synopsis... Southern portions of an upper trough will sweep east across the Great Lakes during the day and into the Northeast overnight, with relatively weak flow into the Plains with an upper ridge. A cold front will progress toward the lower Great Lakes and into the OH Valley late, accelerating across New England into Wednesday morning. Ahead of the front, dewpoints in the 60s F and pockets of heating will lead to several hundred J/kg MUCAPE into parts of New York and Pennsylvania, where large-scale ascent will be increasing late in the day. Areas of early precipitation will be possible ahead of the cold front during the day, which may limit destabilization. However, a diurnal increase in activity is likely as ascent is maximized, from northeast OH into northern PA and much of upstate NY. Forecast soundings from various models indicate uncertainty in the degree of destabilization and antecedent precipitation. In addition, much of the activity will occur during the evening after peak heating. Given these uncertainties, will maintain general thunderstorms for the area. However, given increasing deep-layer shear and lift, a conditional risk of at least isolated severe gusts cannot be ruled out should this setup trend in a more unstable direction. ..Jewell.. 10/05/2025 $$
