Discussion

An active weather pattern will bring three different “clipper” systems (i.e., fast-moving) into the Northeast US over the next few days. The first of these arrives early today and it will generate accumulating snow in the Philly metro region on the order of an inch or two, but isolated three inch amounts are possible in westernmost sections. This morning’s commute will feature numerous slick spots on the roadways as the snow quickly sticks after arrival and some re-freezing will take place. Another “clipper” system will arrive on Wednesday with snow shower activity likely in the Northeast US - potentially even a few heavier snow squalls - and then brutal cold will follow for Wednesday night and Thursday. In fact, this brutal cold air mass coming for tomorrow night and Thursday will rival some of the coldest air seen all of last winter in parts of the Northeast US. Boston, for example, bottomed out all of last winter at 2 degrees above zero and that low mark from last winter is in jeopardy up there by early Thursday morning. Indeed, single digits are likely up and down the I-95 corridor in the overnight hours on Wednesday going into early Thursday and daytime highs on Thursday afternoon will be hard-pressed to escape the upper teens. Yet another “clipper” system will generate numerous snow showers in much of the Northeast US on Friday before reinforcing Arctic air pushes in to start the weekend. Next week is likely to present additional chances for snow as the overall weather pattern remains quite active.
