Updates

– Region of Moderate and Accumulated Snow Accumulation

The generalized disturbance of the upper level behind the main storm system produces a last layer of snow accumulated in the region. The National Meteorological Service issued a special statement warning motorists of "dangerous traffic conditions" and unseen visibility losses.

It has been snowing for 24 hours and in some areas it is the heaviest in which it has fallen.

The main roads that were treated earlier today and have been swept are again covered with snow. Do not venture if you do not have to. These conditions could last several more hours.

Forecast

Most of us have about 4.5 to 7.5 inches snow on the ground until 4 pm, enough to make the biggest snowstorm in Washington since the January 2016 snowstorm. We are not quite finished yet either.

Light to moderate snow bands over the next few hours will drop another two to three (or even three inches). in a few places) before everything is finally closed after midnight. We have all fallen below freezing tonight, so everything will be refreezing or frozen, making untreated surfaces slippery until Monday morning.

Until Tonight: Light to moderate snow bands will continue over the next few hours, with an extra one to three inches of snow likely to be around 20 or 21 hours. Light snowfall will continue until midnight, but little or no build-up is expected. It should be clear and cold at night. Minimum in our mid-twenties in our coldest places and in the upper 20s in downtown, with a north wind of 10 mph. Untreated surfaces will probably freeze again, creating slippery spots.

Tomorrow (Monday): Temperatures will start below freezing, expect smooth, untreated surfaces. The weather is usually sunny and the cold continues. The peaks will peak in the mid-30s with a light north wind of 5 mph. Partly cloudy and cold tomorrow night with today's low to mid-twenties.

The beginning of a snowy configuration? At the risk of causing unrealistic hype, the model's guidelines suggest that the end of January could be cold and snowy for the east coast. After much of last month with above-average temperatures, this weekend's snowstorm could mark the beginning of a model change.

The next opportunity for a winter coastal storm occurs exactly in a week. Another low-pressure, moisture-laden system will cross the southeastern United States and is likely to reconvert to a coastal depression somewhere on the east coast. There should also be a lot of cold air around you for this hypothetical assumption to be accompanied by freezing precipitation.
