Severe thunderstorms are not expected through tonight across the contiguous United States. ...Synopsis... Across the CONUS the upper-level flow pattern is forecast to amplify as an upper low over AZ/NM moves slowly into the southern Great Plains tonight through early Friday. Weak elevated MUCAPE below 500 J/kg, and sufficient upper-level ascent, will support isolated thunderstorms ahead of the low over the southern Rockies and High Plains within a broad area of mixed-precipitation. Otherwise, ridging and strong surface high pressure on either side of the low will limit the inland return of moisture to much of the rest of the US. Occasional lightning is possible, along and south of a remnant front, near the south TX and southern FL coasts. However, marginal thermodynamics suggests storm coverage may remain quite sparse. With poor overlap of favorable shear and buoyancy for organized thunderstorms, severe weather is unlikely across the country through tonight. ..Lyons/Guyer.. 12/14/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
