Isolated thunderstorms may occur across parts of the Florida Peninsula, Northeast Coast, Mid-Atlantic Coast, and parts of California today, but severe thunderstorms are not expected. ...Synopsis... A deepening surface low, across western Pennsylvania early this morning, will move northeast and continue to deepen before exiting the Maine coast this evening. A cold front will extend from this surface low, mostly offshore along the east coast before crossing the Florida Peninsula. This cold front will cross the Peninsula during the first portion of the day and should be offshore by mid-late afternoon. ...Portions of the Northeast... Some mid 50s dewpoints may advect inland across portions of eastern Massachusetts amid strengthening low-level flow. Despite a strong (60 knot) low-level jet, no severe storms are expected due to the weak instability. ...Florida Peninsula... A cold front will cross the southern Florida Peninsula this morning into the early afternoon. Thunderstorms are expected to persist along this front as it crosses the Peninsula. However, limited instability, and veering low-level flow should keep any severe weather threat minimal while the front remains onshore. ..Bentley/Kerr.. 01/13/2023 Read more CHECK UPDATE ZOOM GRAPHIC
