A Winter Storm Warning is in effect for much of the western suburbs, The Watches will be changing soon to warnings and advisories.

This Afternoon: Increasing Clouds, Mild

Highs: Around 50 | Wind: SE 4-8 mph

Tonight: Areas of Rain and Snow Develop

Lows: 30-35 | Precipitation:  After Evening Rush

Wednesday: Areas of rain and heavy snow-all snow by evening

Highs: Low to Mid 30s | Precipitation: 100%

A Winter Storm Warning has been issued for the District of Columbia, Montgomery County, Howard County, Prince William County, Manassas, Manassas Park, Arlington, Falls Church, Alexandria and Fairfax County. It begins at midnight Wednesday.

The storm set to hit us late Tuesday night into Wednesday in now in the Tennessee-Kentucky area. Everything still points to this storm re-forming over the Virginia Capes and becoming a major coastal storm. 

The biggest challenge, as with every storm, is the rain-snow timing and amount. One of the items we look at to figure it out is the ensemble of many simulations; this one gives D.C. an even 50/50 probability of rain or snow much of tomorrow.

It is likely that by the time you wake up Wednesday, areas west of D.C. will see snow on the ground, but closer to the D.C. Metro less snow is expected to be on the ground. Southeast of the city, a fair amount of rain may mix in, limiting morning snow cover.

As Wednesday morning progresses into the afternoon, the surface low will grow stronger and rain in the immediate D.C. area will change to snow for a sloppy, snowy evening rush with increasing winds.

Here's our latest snow total for the region by Wednesday night as the storm winds down:

The biggest threat with this storm is downed trees, with power outages likely to the west of D.C. due to heavy wet snow and increasing winds Wednesday afternoon.  The New Jersey coast will get hit hard again also.

Thursday will be breezy and cold with highs near 40, but temperatures will rebound by the weekend.
