Discussion
This will be a stormy week in the Mid-Atlantic region with two storms to deal with during the next few days. Today’s storm will begin with all rain, but as colder air filters in from a strengthening high pressure system to the north, a changeover to snow is quite likely by the late morning or mid-day hours. There can be a couple inches of accumulation before the snow winds down later in the afternoon. A second and more impactful storm will arrive by mid-day or early afternoon on Wednesday with snow initially for the region. Sleet and freezing rain will then likely mix in for a period of time before changing back to snow at night. This period of mixed precipitation will limit total snow accumulations with preliminary snowfall estimates of 3-6 inches in the Philly metro area, 6-12 inches in the nearby N/W suburbs, and 12+ inches in the far N/W suburbs. Snow showers will linger through the day on Thursday and it'll remain much colder-than-normal right into the upcoming weekend.
