Severe thunderstorms are not forecast on Thursday or Thursday night. ...Synopsis... Thunderstorm potential appears negligible across much of the CONUS, with low-probability highlights over parts of the Pacific Northwest, northern Rockies, and Midwest. A dampened shortwave trough consisting of multiple embedded impulses will shift from the Northwest early Thursday into the North-Central States by early Friday. Nearby presence of the mid-level cold core may be sufficient for scant buoyancy across the northern Rockies and very isolated thunderstorms on Thursday afternoon. Downstream, non-NAM guidance suggests a strengthening low-level warm conveyor on Thursday night could yield scant elevated buoyancy across the Lower MO/Mid-MS Valleys. This may support isolated embedded thunderstorms on the trailing/southern portion of an emerging rain swath. In the Pacific Northwest, after a brief period of weak mid-level ridging on Thursday morning, the next upstream trough should move east from the northeast Pacific and impinge on the coast Thursday afternoon. This setup appears more thermodynamically limited relative to the D2 MRGL threat, with negligible surface-based buoyancy largely progged where deep-layer shear is strong. ..Grams.. 11/04/2025 $$
