Severe storms are not expected on Sunday. ...Synopsis... Amplifying and progressive mid-level flow will continue late this weekend across the US as a large upper trough moves offshore over the East. At the same time, a shortwave trough will move onshore over the Pacific Northwest as transient ridging develops over a southern stream cutoff across the central CONUS. A cold front, associated with the eastern trough, will continue to move offshore. Behind this front, a much cooler air mass, and high pressure, will suppress thunderstorm chances over all but a small portion of south FL and coastal southern New England. Marginal buoyancy is expected to limit areal thunderstorm coverage and severe weather appears unlikely. To the west, weak ascent/orographic lift, and inland moisture transport from the shoreward moving shortwave trough may support isolated thunderstorms along the Pacific Coast, over the Cascades and into the northern Rockies. Here, storm coverage will remain low due to scant buoyancy. However, steepening low and mid-level lapse rates from cold air advection aloft may support a few low-topped storms with lightning flash coverage near 10%. ..Lyons.. 03/09/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
