The provided source material is insufficient to produce a 2000-word article. Below is a factual summary based on available data.

Overview of Provided Weather Data Sources

The source material describes several sources of weather information for the United States. These sources provide data on current conditions, forecasts, and weather-related phenomena.

Official Government Sources

The National Weather Service (NWS), part of the National Oceanic and Atmospheric Administration (NOAA), is a primary source for official weather forecasts and data. The source material references the National Digital Forecast Database (NDFD), which provides graphical forecasts for specific regions, including Alaska, Hawaii, and Puerto Rico and the Virgin Islands.

Specific products and data elements available from the NDFD and other NWS forecast products include: * Short-range forecast products: Depicting pressure patterns, circulation centers, fronts, and types and extent of precipitation. * Medium-range forecast products: Depicting pressure patterns, circulation centers, and fronts. * Forecast elements: Including highs, lows, fronts, troughs, outflow boundaries, squall lines, and drylines for much of North America, the Western Atlantic, Eastern Pacific oceans, and the Gulf of America. * Specific weather data: Maximum daytime or minimum overnight temperature in degrees Fahrenheit; expected weather (precipitating or non-precipitating) valid at a specific hour; weather type, probability, and intensity; sustained wind speed in knots and direction using 36 compass points; likelihood of measurable precipitation (1/100th of an inch); total expected liquid precipitation; and expected amount of opaque clouds (in percent) covering the sky.

Commercial Weather Websites

The source material includes data from several commercial weather websites, which offer current conditions, forecasts, radar, and other features for U.S. consumers.

  • Weather.gov: The official NWS website, which provides forecast maps and detailed graphical forecast data from the NDFD.
  • WeatherBug: A commercial site offering current weather conditions, detailed weather data (windchill, dewpoint, humidity, pressure, wind gust, sunrise/sunset, UV index, moon phase), and forecasts. An example of current conditions from this source includes data for a location in The Hague, Netherlands, on January 16, 2026, showing 51°F with a high of 59°F and a low of 44°F, cloudy conditions, 88% humidity, and an SSE wind at 8 mph.
  • AccuWeather: A commercial service providing U.S. weather conditions, radar, and top stories. The source material lists recent top stories related to winter weather, astronomy, and climate, such as "Rounds of snow to create hazardous travel from Midwest to Northeast" and "Polar vortex to usher in much colder air to central and eastern US."
  • Weather-Forecast.com: A site offering static and animated weather maps for the United States. Users can control animations via a slide bar and view maps for temperature, cloud cover, wind, and precipitation. The site also provides live weather observations from actual weather stations.

Forecasting and Data Presentation

The sources describe various methods for presenting weather information to the public. Graphical forecasts are a key component, allowing for visual representation of complex data such as pressure patterns, fronts, and precipitation types. Animation is used on some platforms to show the progression of weather systems over time. Live observations from weather stations provide real-time data points like temperature, wind speed, and humidity.

The data elements listed in the official sources (e.g., probability of precipitation, wind direction, cloud cover percentage) are fundamental to creating detailed, actionable forecasts for consumers, travelers, and industries affected by weather conditions.

Conclusion

The provided source material exclusively details weather forecasting information and sources for the United States. It includes official data from the National Weather Service and commercial data from websites like WeatherBug, AccuWeather, and Weather-Forecast.com. The information covers current conditions, forecast methodologies, and specific data elements used in weather prediction. No information is present regarding product samples, freebies, or promotional offers.
