Severe potential is low Tuesday. ....Synopsis... A strong upper trough over the central Plains is forecast to intensify as a powerful mid-level speed max approaches from the northwest. The trough will deepen and move eastward, settling over the mid MS Valley as it merges with a broader low over the eastern US. In response to the deepening trough, an elongated surface low will develop along a strong cold front as it begins to surge south over the southern Plains. Ahead of the front, a secondary surface cyclone over the Red River will consolidate and deepen as it matures across the mid MS Valley. Southerly low-level flow ahead of the deepening surface cyclone may allow for some modest moisture return over parts of the TX South Plains early Tuesday. However, in the wake of the earlier frontal passage, moisture depth is likely to be limited. Weak buoyancy may develop along the front as the upper trough and cool mid-level temperatures overlap the modestly moist air mass. While isolated storms are possible along the front over southern TX, rapid undercutting and limited buoyancy suggests little if any severe risk. Otherwise, isolated thunderstorms are possible ahead of the cold front over parts of FL and the Outer Banks. The limited overlap of favorable buoyancy and shear will again support little if any severe risk through early Wednesday. ...Lyons.. 10/26/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
