Latest (05/00z) ECENS/GEFS output suggests than an initially prominent mid-level ridge over the Canadian Northwest Territories will gradually become suppressed, with the center of higher heights shifting east-southeastward toward northern Manitoba through early this weekend. Preceding this feature, it appears that a significant positively tilted trough will pivot through northwestern Ontario and the upper Great Lakes, before digging through the lower Great Lakes and upper Ohio Valley vicinity. As this occurs, it appears that Debby's remnant lower/mid-level circulation will finally accelerate northeastward out of the Southeast, and offshore of the Mid Atlantic coast by next weekend. While it might not be out of the question that this could occur in a manner supportive of an appreciable increase in potential for convection capable of producing tornadoes across parts of the Carolinas, Virginia and Delmarva Peninsula vicinity, probabilities for this still seem generally low at this time. Otherwise, modest westerly to northwesterly mid/upper flow developing across the northern Rockies into northern and central U.S. Great Plains, around the periphery of a prominent ridge shifting from the Four Corners into southern Great Plains, may be conditionally supportive of organized convective development through much of the period. However, guidance continues to generally indicate that seasonably modest destabilization will tend to limit the severe weather potential. ...Kerr.. 08/05/2024 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
