9:30 am – Winter Weather Report issued
The National Meteorological Service has issued a winter weather forecast for the area from 10pm tonight until 10am Friday. The notice does not include the counties of St. Mary's and Stafford, where there is little or no snow accumulation. The meteorological service expects to receive between 1 and 3 inches of snow and slush in the immediate area of Washington and between 2 and 4 inches in the northern suburbs. We think that these numbers could be very high and will publish our own forecast of accumulation around 11 o'clock.

Today (Thursday): The sunny skies are pleasant, but a north wind of 10 mph makes the peaks of the mid-40s less comfortable. Clouds should start filtering late in the afternoon from the west. Trust: high
Tonight: Clouds increase rapidly in the evening and snow or mixed precipitation may begin to fall around midnight or shortly thereafter. It is possible that snowfall can accumulate quickly and, despite some initial fires, they could accumulate, even on the roads. We will post our accumulation map later this morning, but a first reasonable estimate is one to three inches to the north and west of the Beltway and a coating up to two inches elsewhere, where mixed precipitation is expected to decrease. The overnight lows are in the top 20 to 30, with a light breeze from the northeast. Trust: Way

Tomorrow (Friday): It is likely that the snow will decrease rather early in the morning, but the clouds will remain in place throughout the afternoon, accompanied by an uneven drizzle. The highs go from north to north at 30 in the city and south. The breeze is always very light. Trust: Way
Tomorrow evening: Some additional showers, possibly mixed with snow, may form, but will be very light and additional snow accumulation is very unlikely. Light winds from the northeast prevail, with troughs in the mid-thirties. Trust: Lower average
Saturday cloudy remains, and a few drops of rain are always a risk, especially in the morning. The ups should have trouble reaching the middle of 40 years. The night falls from the lowest in the upper part of the twenties to very low, with some breaks in the clouds late at night. This is almost the only chance to see the last moonlight with Venus, Saturn and Jupiter in the eastern skies of dawn. Trust: Way
Clouds increase rapidly Sunday in the morning, and precipitation will probably begin to fall in the afternoon. The exact trajectory of the storm is still very unstable and, as such, the type of precipitation is also very unstable. A longer runway to the west and north would mean more rain, but a track to the south would lead to more snow. The daily maximums are about 40 to 45. At night, rain and / or snow are likely to continue as temperatures eventually drop below freezing as precipitation drifts away. The best snow chances on Sunday afternoons and nights are our colder north and west suburbs. Trust: Low
On Monday disappears rapidly as strong northwesterly winds bring much colder, drier air into the area. A powerful air infiltration in the Arctic arrives and may remain a big part of the week. Highs are only in the 30s. Trust: Way
