Like there is one for the tiny storm by Boyce, VA right now I would say that it does, although I would not be surprised is there is some very weak rotation on the cells tonight, as there is some very modest curvature in the hodographs tonight. 1 Link to comment Share on other sites More sharing options...

RDM Posted August 6, 2020 Share Posted August 6, 2020 Yup Yoda - Pouring here now just NW of Vienna. .3" in just a few mins. Deluge. Based on Sterling radar, this is not moving very fast too. Lawyers Road where we live will probably flood, for the nth time this year. Anything over about 1"/hr and it floods/closes. Link to comment Share on other sites More sharing options...

frd Posted August 6, 2020 Share Posted August 6, 2020 Even the end of next week looks to be rather wet according to Mount Holly's long range outlook. I tend to think if this pattern continues maybe over seeding can commence earlier this year, rather than after Labor Day, as @CAPE mentioned . I keep reading that as the Country dries up drier weather may settle into the East on a extended basis . However, this change seems to continue to push out further and further into the future. From Mount Holly AFD : Looks like the late-week period may be interesting, as the front may stall near or in the area, with deterministic models showing multiple rounds of convection occurring in proximity to it. Certainly a heavy-rain threat from a pattern recognition perspective. Link to comment Share on other sites More sharing options...
