Situation in W Atlantic---UKMET continues west outlier

Bill continues to be pulled wnw to nw by the general troughiness (with embedded ULL) to the left of the Bermuda Subtropical Ridge. If this course continues, Bill should remain off the US Coast as forecasted by model consensus. One fly in the ointment. As Bill continues west past the ULL directly to its north, its possible that some of the north component might temporarily diminish some. Allowing for a little more of a WNW shift in the short term. The oncoming deep trough which will pick Bill up could be delayed some in its movement off the central Atlantic coast. Also allowing Bill to swing a little closer to the coast, before finally feeling the trough and then turning quickly toward a more true north. Sat images seem to show the trough moving more definitively through the upper midwest, but at this point lagging further south, not developing yet that good strong S-N flow. This will come. But how close will Bill be to the coast when this happens. UKMET continues as western outlier, with a closer pass to the coast for Bill.
