Severe thunderstorms are not expected on Wednesday. ...Synopsis... A broad upper trough will envelop the CONUS today. At the surface, a deep cyclone will lift northeast across New England and Quebec. Some convection may be ongoing during the morning hours from near Cape Cod northward into Maine. However, meager instability and poor midlevel lapse rates will likely preclude lightning. Otherwise, generally dry and/or stable conditions in the wake of a cold frontal passage earlier in the week will preclude thunderstorm activity across much of the rest of the U.S. east of the Rockies. Further west, a series of shortwave impulses migrating through the western periphery of the CONUS upper trough will foster areas of precipitation from the Pacific Northwest toward the Great Basin. Cold temperatures aloft will support steep midlevel lapse rates and at least areas of weak instability. Isolated lightning flashes will accompany convection along the WA/OR coasts, as well as over parts of the Sierra Mountains into NV/UT. Severe storms are not expected. ..Leitman.. 01/10/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
