The best chance of accumulation from this weekend’s snow event will be on grassy surfaces and trees. Here are the latest forecast models (images courtesy Weatherbell):
Here is the latest 12z Operational European Snowfall Forecast: Generally a dusting in the urban heat island with one to three inches in the suburbs.
Here is the latest European Ensemble which probably has the best idea: Again a general one to three inches with two to four inches the further north and west you go from the metro Area.
GFS Model is interestingly now the most bullish: Basically the higher elevations could probably pick up 3 to 6″ from this storm (those of you at or above 1500 feet)
Last up: The Canadian Forecast Model –
- Rain will break out Saturday during the afternoon/evening hours. The rain will mix with and change over to wet snow.
- Periods of wet snow will fall Saturday overnight through the day on Sunday. The snow may mix with rain in DC points south and east.
- Accumulations will range from a dusting to 1″ inside the Capital Beltway (Up to 2″ could fall there but less likely if temperatures don’t drop to freezing)
- The northern and western suburbs can expect 1 to 3″ of snow from this system.
- Extreme northern Maryland and the foothills of the Blue Ridge mountains (western Loudoun county, Frederick county Maryland) could pick up 2 to 4″.
