11:45 AM | **Snow tomorrow night and Monday from a system that will then explode off the Northeast US coastline…more accumulating snow possible here Monday night/Tuesday along with brutal cold air…as far as the longer-term is concerned – buckle up for that as well!**

Discussion

Sunday night/Monday As today’s coastal storm affects wind down along the I-95 corridor, another storm is already taking shape upstream. A “clipper” type of system is dropping southeastward today into the Northern Plains and it will reach the coastal waters of the western Atlantic Ocean by later Monday. Snow will move into the I-95 corridor region tomorrow night and continue on Monday with a big impact likely on the Monday morning commute along with possible school closings. This snow will be of the dry, fluffy variety - not like the wet snow that fell last night. Preliminary snowfall estimates by later Monday afternoon are as follows: DC region 3-6 inches, Philly region 3-6 inches, NYC region 2-4 inches.

Monday night/Tuesday Once this system reaches the western Atlantic Ocean later Monday, the combination of the relatively warm ocean water and an influx of brutally cold Arctic air from the northwest will cause it to explode off the Northeast US coastline from late Monday into Tuesday. As a result, more accumulating snow could fall in the I-95 corridor on Monday night and Tuesday and it could be substantial. New England is quite likely to get walloped by an all-out wind-blown blizzard on Monday night and Tuesday and the I-95 corridor region from DC-to-Philly-to-NYC is going to be a close call. Brutal cold air reaches our region Monday night and it’ll last for much of the week. In fact, the overall weather pattern looks absolutely frigid for the foreseeable future – perhaps right through February -and there will be multiple snow threats.
