Severe thunderstorms are not forecast through tonight across the contiguous United States. ...Synopsis... A large, mature mid-latitude cyclone is centered over the eastern NE/KS border vicinity. This cyclone is expected to move gradually into MO, while becoming increasingly vertically stacked with time. Cold and dry air mass associated with this cyclone will dominant the sensible weather across much of the CONUS. The only exception is from the coastal Southeast through the Mid-Atlantic States. Here, an extensive warm conveyor, originating over central Mexico and the western Gulf of Mexico and splitting over the Mid-Atlantic, will contribute to broad isentropic ascent. Strongest ascent is ongoing over the SC vicinity, where enhanced low-level southeasterly flow is augmenting the modest ascent within the warm conveyor. This low-level flow is forecast to continue throughout the period while gradually shifting northward, resulting in prolonged isentropic ascent and a continued threat for isolated thunderstorms embedded within the broader precipitation shield. Highest thunderstorm coverage is expected over the western Carolinas. Some favorable low-level shear may exist across the central/eastern Carolinas, but this shear should be displaced west of any surface-based buoyancy, limiting the severe potential. ..Mosier/Thornton.. 12/26/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
