The risk for thunderstorms appears negligible across much of the U.S., Saturday through Saturday night. ...Discussion... While the center of a broad, initially intense, surface cyclone is generally forecast to weaken while migrating northeast of the Great Lakes region during this period, models suggest that a remnant mid-level circulation may begin to deepen while turning northward toward James Bay. In their wake, Arctic air, initially banked up across the northern Great Plains into the Rockies, appears likely to surge southeastward through much of the southern Great Plains and lower Mississippi Valley by late Saturday night. This will reinforce a preceding cold front, which is forecast to advance offshore and away from much of the Atlantic Seaboard, while stalling across the southern Florida Peninsula through southeastern Gulf of Mexico. Coupled with low-level warming and moistening, dynamically driven steepening of lapse rates above a cool/stable boundary layer may be contributing to convection capable of producing lightning near southeastern New England coastal areas early in the period. Otherwise, some weak thunderstorm development will remain possible along the stalling front, though this may remain mostly confined to areas near and offshore of the southern Florida coastal waters. ..Kerr.. 01/11/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
