Severe thunderstorms are not expected on Saturday. ...Synopsis... A low-amplitude shortwave trough is forecast to move across the Mid-Atlantic and Northeast States during the day on Saturday. Surface low associated with this shortwave will likely be over central NC early Saturday before then moving northeastward in tandem with its parent wave and ending the period just off the southern New England coast. Cold front attendant to this surface low will likely stretch back westward across southern GA and the western FL Panhandle early Saturday before gradually shifting southeastward and becoming increasingly diffuse with time. Isolated thunderstorms are possible within the warm-air advection zone near the low over coastal NC Friday morning. Isolated thunderstorms are also expected in the vicinity of the front from southern GA and the FL Panhandle through the FL Peninsula. A low-amplitude shortwave trough is forecast to move from the central Gulf of Mexico through northern FL Saturday evening into Sunday morning, helping to foster additional thunderstorm development behind the primary frontal zone throughout the evening. In all of these cases, limited buoyancy and weak vertical shear should mitigate the severe thunderstorm potential. Broad upper troughing is expected to deepen across the western CONUS while an embedded shortwave trough progresses within its base from central CA across the Great Basin and central Rockies. Despite relatively cool surface conditions, very cold mid-level temperatures associated with this trough will support steep lapse rates and limited buoyancy, mostly from the Pacific Northwest coast and over the Sacramento Valley. Some isolated thunderstorms are possible throughout the period in these areas. Additionally, a few updrafts may become deep enough along the frontal band as it moves through the Great Basin to produce lightning. ..Mosier.. 03/01/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
