Just about 24 hours after this storm departs, another system may bring additional (though light!) snow to the D.C. area.

Our current snow storm hasn't even departed the region yet and more snow is likely later this afternoon and evening as the upper-level low spins overhead.

**Update on tonight's snow***  Latest guidance is depicting the heaviest snow to fall between 4pm and 11pm, with the greatest threat along and east of I-95. Try to plan to stay off the roads as some isolated totals close to 4 inches may be possible during this time. Other areas may see 1 to 2 inches of additional snow tonight.

On to the next system... A disturbance over the northern Rockies will push through the Midwest over the next 24 hours before landing on our doorstep Friday night.

Unfortunately, this will bring the possibility for more snowfall in the area. The good thing is we won't tap into any Gulf or Atlantic moisture and snow accumulations should be light.

Snow should begin Friday night after 10pm and continue through early Saturday morning. Total accumulations at this point appear to be around 1 to 3 inches across the region, with the higher totals northwest of D.C. There are some hints that a mix to rain will also be possible south of D.C.

We'll of course be watching this system closely and will have a full update live on ABC 7 News at 4pm, 5pm and 6pm.
