The below update was part of a recent Premium forecast relating to a light snow event expected to hit the region tomorrow.  Minor travel and potentially school impacts are expected, as outlined in the forecast.  To see the potential school and travel impacts, subscribe here.  Otherwise, below is the forecast timing and accumulations for the light snow tomorrow:

Tomorrow will start partly cloudy with increasing clouds through the morning.  Very light snow showers break out across the region between 9 AM and 11 AM, likely remaining quite light into the early afternoon.  The largest change in short-range guidance has been to show that any snow through 1 or 2 PM will be quite light as over-running precipitation struggles to accumulate.  No more than half an inch of snow is expected through 1 PM now, with questions as to what exactly happens after.  Following that light snow, coastal areas could see a pause in snow between 1 and 3 PM as a dry slot moves across the region; light snow may still continue inland with slightly better orographic lift.   A moderate burst of snow between 2 and 6 PM is still a possibility though not a guarantee, as some modeling still shows almost all steadier snow further inland.  Then, lingering snow showers look to be a possibility through much of the evening, finally winding down between 10 PM and 2 AM.  We clear out from there into Wednesday morning.

Accumulation forecasts have become a bit more complicated as it appears the front end of the storm will bring a bit less snow than currently forecast.  It is hard to find evidence of widespread amounts of 2-3 inches like the National Weather Service is calling for, and even though there may be decent snowfall ratios this appears overdone.  Instead, I am calling for a coating-2 inches of snow regionwide now.  Most regions will likely see around an inch falling primarily in the afternoon and early afternoon.  Inland and far inland areas could still see isolated areas of up to 3 inches where the best lift is, but those look to be isolated much more so than widespread, as generally an inch or two of snow is expected.
