Severe thunderstorms are not expected tomorrow (Sunday). ...Synopsis... An upper low will meander over the lower Hudson Valley and upper ridging will prevail over the Plains as an upper trough impinges on the West Coast tomorrow (Sunday). A surface low will develop over the Great Basin ahead of the approaching upper trough, with a weak surface low over northwestern TX encouraging low-level moisture advection across the Plains, with isolated to widely scattered thunderstorms expected across both regimes. Deterministic guidance consensus shows a general lack of overlapping buoyancy and vertical wind shear over the Great Basin to the Plains states, suggesting that severe potential should be quite limited, as also shown by the latest ML/AI guidance consensus. ..Squitieri.. 09/26/2026 $$
