Updates

at 8:15 pm. – Snow totals rise as the radar fills. An inch in many areas.

Although not heavy, the snow is slow and steady and begins to accumulate. We now have many reports signaling about an inch across the region with a range of about 0.5 to 1.5 inches.

A radar revealed a gap in the snowfall southwest of Washington, but it has been filled since then and light to moderate snow has appeared. to fall everywhere. This should continue to be the case for the next few hours and by midnight most places should be about 2 inches.

The road conditions continue to get worse, so please slow down, if you have to go out. Better yet, stay in it.

– Road conditions deteriorate as snow intensity increases

In recent hours, snow was generally light and now it is falling faster. As a result, road conditions are deteriorating.

The radar shows a moderate snow band over the Beltway at the moment. The snow is somewhat weaker in the southwest and its intensity may decrease a little later in the evening. But then, it should resume as the night progresses.

Up to now, most areas have experienced a thick coating. Here are some pictures showing local roads and the rising snow:

– The snow is there and it sticks

The storm arrived at the late hour this afternoon, and after all that we see from our readers, the snow sticks to the grass and even to the roads in the subway. At 1730, the roads are wet but not slippery, but the shoulders are paved.

Up to now, the intensity was uneven, varying between snowflakes and what we would call "moderate snowflakes", but there is a heavier snow band moving north in the immediate subway now, which will likely reduce road temperatures enough to allow it to hold. If you're out tonight, be careful not to roll slowly.

Detailed Forecast

The snow that started late this afternoon will increase tonight and conditions will gradually deteriorate. The first phase of the storm, until about midnight, will drop an inch.

The second phase of the storm will unfold in the morning of Sunday morning, when the developing low pressure system will be close enough to generate heavy snowfall until Sunday morning, when the essential of the buildup should occur – adding several inches more to the snow tonight.

The storm will begin to fly to the seaside on Sunday afternoon, but the atmosphere will remain unstable in the region. allow the snow of varying intensity to extend into the evening.

Night to: Light snow covers the area until the early hours of the evening. Accumulations should be mostly light early in the evening. Snowfall is likely to intensify as the evening progresses. For those who have evening plans, wait for about one to two inches by midnight, but some locally higher quantities can not be ruled out. Untreated roads and surfaces will become really slippery.

Snowfall rates will increase overnight, especially in the southern parts of the country, with an additional 1 to 3 inch drop likely to fall between midnight and 6 am on Sunday morning. The minimums will hover in mid-twenties, with light winds coming from the northeast at 5-10 mph.

Tomorrow (Sunday): The trips will probably be dangerous, as light to moderate snow continues on Sunday morning. Pockets of heavy snow, especially south and east of DC are possible. The rate of snowfall should slowly begin to decline during the afternoon, even though it is likely that we will continue to observe scattered snow areas that will persist in the evening.

Expect an additional snow accumulation of a few inches in the middle of the afternoon. one-inch dusting expected in the evening (although we may need to adjust these quantities). Highs range from low to mid-thirties with northeast winds of 10 mph.

Scattered snow showers completely cut off completely before midnight Sunday, leaving us with a cloudy and cold spell. Thanks to the new snow cover, the depressions will reach 20 to 25 with north winds of 5 to 10 mph.

Why this boom potential? Snow totals have increased steadily over the past 24 hours, as well as the possibility that some places may be found in the "boom" range of our snowfall totals map shown above. The reason is linked to a meteorological phenomenon called frontogenesis.

Later in the evening, when the coastal depression begins to develop, the conditions prevailing in our lower atmosphere will align to maximize the rate of precipitation in what we often call snow bands. It is still very difficult to predict where these bands of intense snowfall will form, but it is clear that they will settle somewhere, and the fact that this happens can make a huge difference in amount of snow over a short distance.
