THE NATIONAL WEATHER SERVICE IN BALTIMORE MD/WASHINGTON HAS ISSUED A WINTER STORM WATCH…WHICH IS IN EFFECT FROM THIS EVENING THROUGH MONDAY AFTERNOON.
* PRECIPITATION TYPE…SNOW…POSSIBLY HEAVY AT TIMES.

Here’s the situation as predicted by the Washington Post’s Capital Weather Gang:
Tomorrow (Monday): Much of the area, except possibly Southern Maryland, probably wakes up to at least a coating to an inch of snow on the ground, unless the initial push of overnight precipitation fizzles out. Early-morning temperatures may still be warm enough such that treated roads are in decent condition. Another inch or two is possible during the day Monday, but that’s only if the storm’s low-pressure center cranks up strong enough and close enough to the coast, which at this point is difficult to say with much confidence. With a steady wind from the north-northeast at 5-15 mph, temperatures don’t do much during the day, staying within a couple degrees of the freezing mark. Confidence: Low
(Updated at 7:15 p.m. Sunday) The National Weather Service on Sunday afternoon predicted 4-8 inches of snow for late Sunday night and Monday.
MCPS announced schools will be closed on Monday. Federal government offices will also be closed.
The NWS issued a Winter Storm Warning for the entire area on Sunday morning, then shifted its projected snow total downward at about 2 p.m.:
…WINTER STORM WARNING REMAINS IN EFFECT FROM 7 PM THIS EVENING TO 6 PM EST MONDAY…
* PRECIPITATION TYPE…FREEZING RAIN…SLEET…AND HEAVY SNOW.
* ACCUMULATIONS…UP TO ONE TENTH INCH OF ICE…FOLLOWED BY 4 TO 8 INCHES OF SNOW.
* TIMING…RAIN CHANGES TO FREEZING RAIN AND SLEET FROM NORTH TO SOUTH THIS EVENING THEN BECOMES HEAVY SNOW LATE TONIGHT THROUGH MONDAY.
* TEMPERATURES…FALLING INTO THE LOWER 30S THIS EVENING…THEN DROPPING INTO THE LOWER 20S OVERNIGHT AND MONDAY.
* WINDS…NORTH 10 TO 15 MPH. GUSTS TO 25 MPH LATE TONIGHT AND MONDAY.
* IMPACTS…HAZARDOUS TRAVEL DUE TO ICE AND SNOW THROUGH MONDAY. BOTH THE MONDAY MORNING AND AFTERNOON RUSH HOURS WILL BE AFFECTED. POWER OUTAGES ARE POSSIBLE WITH THE COMBINATION OF ICE AND HEAVY SNOW.
That’s enough for Montgomery County to declare a Snow Emergency starting at midnight.

Montgomery County is now under a Snow Emergency Plan and a Snow Emergency. It is illegal to park vehicles along designated snow emergency routes and cars parked on the routes will be closed.

State road officials say the evening commute could turn treacherous. The State Highway Administration asked that people wrap up their plans before Tuesday afternoon:
State highway crews are loaded up and ready to confront the latest winter blast scheduled to come through Maryland all day today. Last night crews filled their trucks with salt, pre-treated roads and then settled in for what promises to be a very busy day. As crews prepare, the Maryland State Highway Administration (SHA) reminds travelers to prepare for their safety and the safety of others. The snow is expected to fall throughout the day beginning with the morning rush hour, making the potential for treacherous commutes probable, with the worst occurring during the evening rush hour.
“If you can stay home today, please do so. If you must go out, try to wrap up your plans early to be settled in before this afternoon,” said SHA Administrator Melinda B. Peters. “While out, give yourself plenty of time and drive to the conditions of the road. The snow is expected to be heaviest in the afternoon so caution is urged all day long.”
The Town of Chevy Chase has reminded residents that they must park their cars in driveways or on the even-numbered side of the street to ensure safe passage for snow plow crews.
