Aside from the strong synoptic winds, but nevertheless associated with upcoming low, looks there like might be a brief period of low-end convective potential tucking in behind, or the in the vicinity of, the cold front/triple point surging east, initially over central ROI then over N England between 12-15z, as cool mid-levels and forced ascent with trough overrides slightly moist low-level air mass. This being situated ahead of main zone of highest winds which arrive in the evening.
700/500mb RH output suggests adequate clearance will appear for a time, so convection possibly allowed to get going and not be swamped by general cloud and rain. Shear environment perhaps conducive to rotating updrafts, should anything of interest develop, given strong, slightly diverging, jet winds aloft with winds increasing with height, though proper directional shear not so much apparent.
Probably come to nothing, but thought it worth adding to the discussion.
