Severe thunderstorms appear unlikely across the CONUS Saturday. ...Synopsis... On Saturday, a large upper trough will move out of the northeastern states, with a weak upper ridge moving across the Plains and toward the MS Valley. To the west, a large upper trough will continue eastward across the Great Basin and much of the central and northern Rockies. A lead wave will likely pivot northeastward toward the Dakotas late. At the surface, a large area of high pressure will exist from the southern Plains into the Southeast, maintaining stable conditions. Low pressure will exist ahead of a cold front from the eastern Great Basin into the northern High Plains by late in the day. A low chance of a few lightning flashes may exist along the coastal Pacific Northwest where cold temperatures aloft may result in weak buoyancy. Otherwise, minimal activity will be possible over parts of central ID and vicinity as lapse rates steepen. ..Jewell.. 11/22/2024 $$
