Speaker Notes:

RUC analysis at 16z indicated similar patterns to what was being forecast by the NAM and GFS models. This slide shows a pronounced maxima of 700 mb frontogenesis across northern Pennsylvania and eastern NY, co-located with an area of reduced stability over northeast Pennylvania and southeast NY.
