Rainshadow Posted August 7, 2019 Report Share Posted August 7, 2019 Haven't posted a AWC outlook map all summer. They are pretty good with this. ...Eastern Seaboard... An upper-level trough will move across the eastern states today as southwest mid-level flow remains in place ahead of the trough from the Mid-Atlantic into New England. At the surface, a cold front will advance slowly southeastward across the lower Great Lakes. A pre-frontal trough will deepen across the Eastern Seaboard. Surface dewpoints ahead of the pre-frontal trough will be in the upper 60s F to near 70 F. As surface temperatures warm today, a corridor of instability will develop from the eastern Carolinas northward to eastern New York and western New England. As the upper-level trough approaches, scattered to numerous thunderstorms should develop west of the strongest instability with convection moving east-northeastward across the region. Although deep-layer shear is forecast to be in the 20 to 30 kt range in much of the eastern states, steep low-level lapse rates will make conditions favorable for damaging wind gusts with the better-organized multicell line segments. The severe threat should be maximized in the mid to late afternoon. 1 Quote Link to comment Share on other sites More sharing options...
