6:15 am – Heavier band of morning snow possible south of DC
Earlier this morning, the National Weather Service Storm Prediction Center highlighted an area including DC, Northern Virginia and Southern Maryland for the risk of moderate to heavy snow falling at a speed of about or more than 1 inch per Time in the time frame 6-10 am (see graphically below). This is due to a jet strip – a particularly fast part of the jet stream high up in the atmosphere – which can cause extra "lift" in the atmosphere and thus heavier snow. A fast 2 to 3 inches of snow is possible if and where this heavier slope develops, which seems more likely to the southern half of this zone, but can affect the area as far north as DC's southern suburbs.

FORECAST IN DETAIL
Our first snow in 2019 is an important one. And lucky for us, it's a Sunday so most can stay home and enjoy the show comfortably. The snow continues at varying intensity throughout the day. When we enter the working week, cold air remains, but some sun and moderate temperatures mean that our snow does not stay too long.

Today (Sunday): Flager continues to fly through much of the day so you can just as well relax and enjoy the coffee before going out to shovel. We continue to build on the many inches that fell last night and night, with totals in the immediate metro area about 5-10 inches in the evening, with up to approx. 12 inches possible in some places mainly south of DC. Temperatures are stable throughout the day, holding in the upper 20s to near 30 with winds from the northeast around 5-10 mph. Confidence : Medium-High
Tonight: Light snowfall and flurry could last the night, but they are mostly just fun to watch and should not add much more to snow totals. It's a nice evening to go for a walk around the neighborhood and enjoy the snow we've been waiting for so long, just make sure to pack up. Overnight runners fall into the 20's with virtually cloudy skies and enough of a northern breeze to be noticeable. Confidence: Medium High

Tomorrow (Monday): A few bright snow showers can dwell early before the sun begins to emerge, although it will take a while to melt our snowpack, As a fresh shot of cold air limits heights to the low-to-mid 30's. Nevertheless, partly sunny skies should help melt the narrow spots out of the way at noon. The winds remain light and out of the north. Trust: Mellemhøj
Tomorrow evening: Clouds continue to clear through the evening and overnight, allowing temperatures to dip into low to mid 20's . Wet spots developed in the afternoon sun can be frozen, so beware of slippery spots that go on Tuesday morning commute. Trust: Mellemhøj

A high pressure
High pressure set up over the southeastern US Tuesday and Wednesday and it helps moderate our temperatures a little for our midweek. Mostly sunny clouds increase the temperatures in the mid 40's or so (well, the snow cover was fine while it lasted). Temperatures fall again in the 20s again on Tuesday night, which means a few smooth spots still possible early Wednesday morning. Trust: Medium
