Discussion

*A high impact weather event today and tonight in the Mid-Atlantic region with heavy rainfall, the potential for widespread flooding, and a tornado threat as well*. The remnants of Ida will get “re-invigorated” today as this tropical depression encounters a stalled-out frontal boundary zone and interacts with a strong upper-level jet streak. Flooding is a serious concern for the next 24 hours or so given the already well-saturated grounds and the prospects of several inches of rainfall. Cool air for early September will follow the storm for Thursday, Friday and Saturday confining afternoon highs to the 70’s in most spots.
