All values are relative to each source’s normal. “Full Winter” follows each source’s stated season; see the period on each card. Monthly values are never filled from seasonal averages. Precipitation includes rain and melted snow.
How consensus is calculated: A simple majority of available entries for each period and measure, counting each released forecast provider once. Both almanacs are excluded and listed in a separate table below. Unknown values are excluded; one available source is “Limited data,” and no majority is “Mixed.” Counts show agreement among sources, not forecast probabilities. Seasonal windows and local interpretations differ. Snow coverage remains limited and includes a DC proxy; Equal Chances means no favored snowfall category, not a forecast of normal snow.

BAM favors above-normal winter temperatures and precipitation, with equal chances for snowfall in Loudoun / Northern Virginia. Its December and January maps also favor warmer and wetter conditions.
Seasonal temperature and precipitation cover December–February (DJF); snowfall covers November–March (NDJFM). Values are regional interpretations of the supplied BAM maps, consistent with the user’s local reading. Equal Chances does not predict normal snowfall. February monthly values remain ? because no February-only map was supplied. Original public publication URLs have not been supplied; the earlier Bayer January 2026 material remains excluded.

A warm start, with the warmth easing later in winter. Northern Virginia remains on the above-normal side of all three monthly temperature maps.
Temperature values are local readings of the published national maps. February is close to the transition toward near-normal conditions farther south. The seasonal precipitation map favors wetter conditions. The article does not provide local monthly precipitation or snowfall totals.

WeatherBell
Preliminary
Meteorological outlook · August 9, 2026
The preview lists 15–20 inches for Washington, DC, described by the source as slightly above normal. That is a DC forecast, not a Loudoun snowfall total.
The temperature map places Northern Virginia near normal (−1 to +1°F), but covers November–March. East Coast precipitation is favored to be heavier. Snow and precipitation summarize the broad winter preview; monthly categories are not supplied. The DC snow category is used only as a nearby regional proxy.
Forecast period: Temperature: November–March; snow: source winter season

OpenSnow
Preliminary
Meteorological outlook · August 11, 2026
Above-normal temperatures and precipitation east of the Appalachians, with equal snowfall chances for Virginia.
The source explicitly identifies Virginia for equal snowfall chances and the eastern Mid-Atlantic for wetter conditions. January and February have stronger regional snow signals, especially in the Southern Appalachians; those analog signals are not month-specific Loudoun forecasts, so monthly cells remain ?.

Climate Impact Company
Preliminary
Meteorological outlook · Issued August 26; posted August 27, 2026
An initial warm, stormy winter outlook for the region. A September 8 update puts Washington, DC’s winter heating demand below normal, supporting the warm signal.
December warmth and a stormier February along the East Coast are regional interpretations of the text. Monthly maps exist, but their local values could not be verified; other monthly cells remain ?. The DC heating-degree-day forecast is a nearby proxy, not a Loudoun temperature number. No local snow category was verified.

Old Farmer’s Almanac
Preliminary
Almanac outlook · August 31, 2026
The Appalachians outlook favors colder, drier and snowier conditions. Leesburg is assigned to the Appalachians in the Almanac’s location lookup.
The table uses the dated 2026–27 Appalachians forecast, not the rolling location page’s older annual narrative. The nearby Atlantic Corridor has a different outlook: warmer, drier and slightly less snow. This regional boundary matters across Northern Virginia; the Appalachians row is a Leesburg-based interpretation. Listed coldest/snowiest spells are not full-month anomalies.
Forecast period: Source winter season; includes spells outside DJF

Farmers’ Almanac
Preliminary
Almanac outlook · Updated September 3, 2026
Its Southeast zone, which includes Virginia, favors near-normal to slightly cooler temperatures and above-normal precipitation.
The table applies the source’s very broad Virginia zone to Loudoun. Adjacent DC and Maryland are in a different zone with near-normal precipitation. The source’s “low” snow risk is not an above/below-normal snowfall prediction, so snow remains ?. No monthly Loudoun categories are supplied.
Forecast period: Source season: late November–March

Keep the location in view
Loudoun spans lower elevations and the Blue Ridge. National maps and broad regional forecasts cannot capture every local difference. R marks our interpretation of those maps, a regional boundary or a nearby-city proxy. D identifies an explicit statement for a region containing Loudoun; it is still not a county-specific forecast.
A winter tendency is not a storm forecast
A warm winter can still bring a major snowstorm. Wetter does not automatically mean snowier. Equal Chances is not a prediction of normal conditions, and ? is not zero. Providers use different methods and seasonal windows; this table does not rank their accuracy or weight sources by forecasting skill.
