Severe thunderstorms are not expected on Monday. ...Synopsis... A closed upper low over the central Plains will deepen as it drifts east toward the Mid-MO Valley vicinity. Deep-layer southwesterly flow ahead of this feature, and a stronger sub-tropical jet moving across the Gulf of Mexico, will maintain a stream of rich mid-level moisture over the southeastern U.S. At the surface, low pressure over the Mid-MS Valley will lift north toward the Upper Midwest while a trailing cold front shifts east across the Mid/Lower MS Valley, extending from near Lake Michigan to the central Gulf Coast vicinity by Tuesday morning. Southerly low-level flow ahead of the front will allow for modest boundary-layer moisture as far north as the TN/OH Valley vicinity. Dewpoints in the 60s F will reside further south across much of the central Gulf Coast/Southeast. However, widespread cloudiness, ongoing precipitation, and poor lapse rates will limit destabilization, precluding severe thunderstorm potential. Building surface high pressure in the wake of the cold front from the Rockies into the Plains will result in mostly dry and stable conditions. ..Leitman.. 12/23/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
