A wave of low pressure will eject out of the Midwest Sunday afternoon, quickly moving east across the Mid-Atlantic states on Sunday night. A period of rain and snow is likely on Sunday night with some snow accumulations likely on grassy surfaces north and west of downtown DC.
Animation from the latest run of the European Forecast Model:
What an incredible April it has been… the latest forecast models continue to show a clipper sliding very close to the DC Region on Saturday producing some light snow showers. During this time of year it is likely that even if the precipitation falls during the afternoon, the high sun angle would help to warm the boundary layer enough to cause any snowflakes to melt into rain droplets.
As of this evening the models are suggesting that parts of our region may wake up to some light snow showers falling pre-dawn Saturday continuing through the noon hour before a change over to some light rain showers. The system’s track looks to be far enough north to keep accumulating snow across the Maryland-Pennsylvania border points north.

The next two weeks will feature plenty of winter weather here in the Mid-Atlantic with bitterly cold temperatures, hard freezes, and even the potential for accumulating snow.
The image below shows the latest Global Forecast System (GFS) Snowfall forecast through noon on Saturday April 9th … yes for those of you wondering *if* we will see some snow in April… stranger things have happened. The latest GFS (image courtesy Tropicaltidbits.com) has a clipper diving well south of DC next weekend (something to watch).
This weekend will be a roller coaster ride with a little bit of everything:
Steady light rain will fall on Saturday during the morning hours, possibly lingering through the mid-afternoon especially south and east of D.C.
A strong April Arctic Front will blast through the Metro Area overnight on Saturday accompanied by the potential for damaging wind gusts and a rapid fall in temperatures.
