Administrators NorthGeorgiaWX Posted December 15, 2023 Administrators Share Posted December 15, 2023 Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0330 AM CST Fri Dec 15 2023 Valid 181200Z - 231200Z ...DISCUSSION... Medium-range guidance is in good agreement that much of the eastern CONUS will be under the influence of an amplified upper trough early D4/Monday. A low-amplitude shortwave will likely be embedded within the eastern periphery of this troughing over the Mid-Atlantic states. A deep surface low attendant to this shortwave will be stacked below it. This shortwave and attendant low are expected to move quickly northward/northeastward during the day. There is a low probability that enough to the warm sector will come on shore to support deep convection in southern New England. A strong shortwave is also forecast to move through the western and southern periphery of this troughing, moving from the Mid MS/Lower OH Valley southeastward into the Mid-Atlantic/Carolinas on D4/Monday. This shortwave is then expected to continue eastward off the Northeast Coast on D5/Tuesday. A dry, continental airmass will be associated with this wave, limiting the severe potential east of the Rockies on D5/Tuesday through at least D6/Wednesday. Moisture return is anticipated to begin across the southern Plains on D7/Thursday, with a cold front possible interacting with this moisture on D8/Friday. Even so, weak buoyancy is currently expected to limit the overall severe potential. Read more View the full article Quote Link to comment Share on other sites More sharing options...
