Severe thunderstorms are unlikely Tuesday. ...Synopsis... A series of upper shortwave troughs will move across the northern Plains and Upper Midwest, as well as the southern Plains to the Mid-MS Valley on Tuesday. Boundary layer moisture will remain modest, with dewpoints generally in the 50s across the Plains and Midwest, while 60s dewpoints remain confined to central/south TX. Warmer midlevel temperatures will preclude much destabilization from the Mid/Lower MO Valley into the Upper Midwest. This will largely limit thunderstorm activity and negate severe thunderstorm potential despite stronger southwesterly flow aloft. Further south across TX, isolated thunderstorms are more likely where weak destabilization will occur amid marginally better moisture and stronger heating. However, vertical shear will remain modest as the region is displaced to the south of stronger flow across the north-central U.S. Furthermore, large-scale ascent will be nebulous within a broad low-level warm advection regime. Overall, severe thunderstorm potential appears low for Tuesday. ..Leitman.. 10/26/2026 $$
