Severe thunderstorms are not forecast across the contiguous United States through tonight. ...Synopsis... A large deep-layer cyclone centered over the mid MS Valley will slowly move east through tonight. An embedded mid-level disturbance will rotate through the outer orbit of the large-scale cyclone and move from the lower MS Valley to Long Island during the period. Weak buoyancy will primarily be relegated to the coastal areas of the Mid-Atlantic states, but it may develop as far inland in pockets across the central Appalachians during the day, as a surface low migrates north near the coast. As a result, scattered showers and a few weak thunderstorms are possible. The limited instability will likely preclude severe thunderstorm activity. Farther west, a potent mid-level trough/closed low west of the Pacific Northwest will feature an impulse moving into the coastal areas of northern CA and coastal OR/WA during the day. Cold 500-mb temperatures will probably yield 100-200 J/kg MUCAPE and a few lightning flashes with the deeper convection as it moves ashore. Elsewhere, tranquil conditions will prevail across a large part of the Interior West across the southern U.S. and influenced by surface high pressure. ..Smith/Bentley.. 12/27/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
