Sunday storm updates...

Jason Samenow @ 1:21 AM

Currently in NW Washington, DC: Light snow, 30 degrees F, ~2" of snow/ice has fallen
Discussion: Light snow will continue but gradually taper off over the next several hours. This will be my last update until tonight as I'm off to hit the slopes. Enjoy the snow and be careful. Give us your snow/ice totals in the comments section.

Currently: Moderate snow, 29 degrees F
Discussion: The National Weather Service upgraded the Winter Weather Advisory to a Winter Storm Warning due to ice accumulation overnight. The precipitation has changed from freezing rain and sleet to moderate snow. Moderate snow should continue for several hours before ending around mid morning. Some snow could linger in the eastern suburbs until noon. Total snow and ice accumulation should be about 2 inches.

Currently: Light sleet and freezing rain, 1/2" of snow accumulation. Temperature, 28 degrees F
Discussion: A shallow layer of warm air aloft has persisted - causing freezing rain and sleet as opposed to snow since about 10pm Saturday. Overnight, that layer may cool enough to change the precipitation back to snow or snow/sleet mix -- particularly north and west of Washington and during heavy precipitation. Precipitation during the day on Sunday is likely to become mostly snow again, and end in the mid afternoon. I'll stick with my total accumulation forecast of 2-3" but if the precipitation type remains ice, amounts will be closer to 1". Be very careful on untreated roads. The combination of snow and ice is causing some treacherous conditions.
