Thunderstorms are not forecast for Friday. ...Synopsis... On Friday, an upper trough will extend from the Great Lakes southwestward into TX, with strong southwest flow aloft from across the Southeast. This trough will be progressive and move off the East Coast by early Saturday, allowing for rising heights/warming aloft across much of the CONUS. Meanwhile, another upper trough will develop southward into parts of the northwestern states. At the

Thunderstorms are not forecast on Thursday. ...Synopsis... A large mid/upper-level trough will persist from the south-central Great Plains into the eastern CONUS on Thursday, as multiple embedded shortwaves move southeastward through the larger-scale trough. Generally dry and stable conditions in the wake of a significant cold intrusion should continue to limit thunderstorm potential through the period. ..Dean.. 01/21/2025 Read more

Thunderstorms are not forecast on Wednesday. ...Synopsis... An elongated upper trough will exit the East Coast early in the day, as another positive-tilt trough moves into the central CONUS. This trough will extend roughly from the upper Great Lakes into the southern Plains. Meanwhile, an upper ridge will exist along the West Coast, with additional disturbances diving south into the northern Rockies. At the surface, a stable air mass

Thunderstorms are not forecast on Tuesday or Tuesday night. ...Synopsis... Thunderstorm potential largely appears negligible across the CONUS through Tuesday night. An exception could be along the Gulf Coast. Shallow and highly elevated convection, predominately producing sleet at the surface, should be ongoing at 12Z Tuesday along the northwest Gulf Coast. Mid-level lapse rates will be progressively weaker with eastern extent downstream, suggesting that lightning production will likely be

Thunderstorms are not expected Monday into early Tuesday morning. ...Synopsis... A large-scale, mid-upper trough will dominate the CONUS, especially from the Rockies eastward. An associated arctic air mass will have enveloped the majority of the CONUS by Monday, including the southeast Atlantic and Gulf coasts. Thus, moisture/buoyancy will be negligible inland, with no appreciable threat for deep convection/lightning. ..Thompson.. 01/18/2025 Read more
