Speaker Notes:

The 22/00 UTC WRF model forecast a closed 700 mb low over northwest Pennsylvania valid at 23/00 UTC; slightly farther north than the Eta or GFS models. The slightly farther north positioning of the 700 mb low may have resulted in a slightly more aggressive northeasterly push to the implied dry slot over Pennsylvania.
