Discussion
This “second half of week” event coming could be the most widespread snowfall so far this season in the DC metro region as a whole. A very active weather pattern will continue for much of the eastern half of the nation during the next ten days or so and there will be multiple chances of accumulating snow and/or ice in the Mid-Atlantic region. A relatively weak system passing by to our north today can cause a bit of freezing rain early this morning and a spotty, light (plain) rain shower from late morning into early afternoon. A stronger system is likely to impact the region in two waves during the second half of the week with one concentrating on the period from later Wednesday into early Thursday and then a second from later Thursday into Friday. Significant accumulations of snow are on the table during this long-duration event from late Wednesday into early Friday. Looking ahead, the late Wednesday-to-early Friday threat won’t be the last one for the region and yet another system could generate snow and/or ice in the Mid-Atlantic region later in the upcoming weekend - and potentially more activity could come next week.
