The American model suggests light rain in the area's colder suburbs could briefly change to some light snow before ending Tuesday morning.

Quite a few D.C. region residents witnessed their first snowflakes of the season Friday, and they could see a few more Tuesday. But as with this week’s snow, you may have to look hard for it and you may not even see it at all.

A couple of days ago, a light accumulation of snow — especially in our colder areas — seemed like a small possibility for Tuesday. But that possibility has shrunk.

Although we’re still expecting the coldest air of the season to trickle into the region Tuesday, most of the precipitation with an incoming front is expected to exit before temperatures fall enough to support snow. In other words, we’re predicting mostly rain that might end as a brief period of wet snow. The best chance to see flakes will be in colder areas north and west of Washington.


The European model forecasts mostly chilly rain as a cold front sweeps through the Washington region Tuesday. A few wet snowflakes could mix in before the rain ends.

“The cold air is just too slow to move east for most of us except near the mountains or up towards the Pennsylvania border to get anything more than a few sloppy flakes of non-accumulating snow before the precipitation ends,” said Wes Junker, Capital Weather Gang’s winter weather expert.

The European and American models are in reasonably good agreement that, at least as of now, the ceiling on this event for snow might be a coating on grassy areas in our colder areas north and west of the Beltway.


The American model shows rain, possibly mixing with and changing to snow briefly.

“With temperatures forecast to be in the upper 30s to low 40s, there is good chance that the precipitation will never even mix with snow around the city and points east,” Junker said. “It’s hard to get excited about our snow chances for Tuesday."

Although more than just some wet flakes seems like a long shot, it will certainly feel like winter Tuesday into Wednesday.

Temperatures in the 50s very early Tuesday morning will fall into the mid- to upper 30s by the late afternoon and then below freezing Tuesday night. Highs on Wednesday will struggle to reach 40, more than 15 degrees below average.
