A pattern change did happen, it just was not as extreme of a pattern change. What has happened is a change in the storm track. Storm track is much further south. These systems will continue to slide to the south of the region just giving a chance of snow there and there with most happening south and east of Boston. Cold air will be locked in place for a while as well. An area of high pressure will move down from Canada and will keep the cold air locked in place through the weekend. A storm system looks to ride the southeast ridge, with cold air solidly in place, even if the placement is not ideal, expect a more wintry outcome towards the end of the 7 day. At this time there has been a trend to a colder solution which means more in the way of snow/sleet and freezing rain other than rain. This is towards the end of the forecasting period so much can change.
