“Someone will likely do 20″+ with this storm, but I think that zone is likely north or northwest of DC,” said FOX 5’s Mike Thomas in a Facebook post on Thursday. “I liked 8-14″ for DCA yesterday, and I still like it today!”

FOX 5’s Tucker Barnes has not released an official snowfall forecast total yet, but says heavy snow is increasingly likely, with precipitation beginning Saturday evening and the peak of the storm unfolding through Sunday.

Barnes says a layer of warm air aloft, even as surface temperatures stay frigid, could lead to pockets of sleet or ice mixing in, which may affect final totals.

Model snowfall potentials, which show a wide range of raw computer simulated outcomes, suggest more than 15 inches could fall in Washington, D.C., and over 20 inches in higher elevation areas north and west of the District, including Cumberland, Maryland.

Barnes cautions that models can fluctuate dramatically from run to run and should be used as guidance while waiting for more stable, realistic forecast predictions. He notes there is often a large gap between model output and actual accumulation.

On Wednesday, Winter Storm Watches stretched across a large part of the country, with more than 175 million people potentially in the storm’s path.
