Models Holding Steady on Conversational Snow Showers on Saturday

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.

Global Forecast System (GFS): Maybe a dusting on the grass if the snow can fall steady enough before the sun comes up on Saturday morning!

The corridor spanning from Pittsburgh across southern Pennsylvania into Philly and NYC (at this time) seem to have the highest probability of picking up several inches of snow out of this Friday night into Saturday!
