Weather Arlington Radar (2024)

FAQs

Which weather radar is the most accurate? ›

The WSR-88D is one of the most powerful and advanced Weather Surveillance Doppler Radar in the world. Since first being built and tested in 1988, it has been installed and used operationally at over 160 locations across the United States, including Alaska and Hawaii.

All DPR closing information will be included on the DPR Inclement Weather Hotline, which is: 703-228-4715. Check Arlington County's Emergency Weather page to learn about county-wide closures and delays.

Blue and green colors represent light-to-moderate rainfall. Yellow and orange colors show moderate-to-heavy precipitation, while red is very heavy rainfall and pink colors inside the red color represent hail of different sizes.

Answer and Explanation: The colors on a weather map indicate the amount of precipitation an area is, or will be, receiving. Generally speaking the darker the color the more precipitation indicated. Light and dark blue usually indicate snow, while dark red and purple mean strong to severe thunder storms.

This comprehensive test analyzed over 25 million weather forecasts in more than 1,000 locations globally, and AccuWeather was the clear winner in high- and low-temperature forecasts, proving to have the lowest average absolute error and the greatest percentage of forecast accuracy within 3 degrees F.

Arlington and Alexandria are mostly in Zone 7b.

On a weather radar map, a tornado is usually indicated by a smaller area of red surrounded by a larger area of green. However, modern radar systems can also indicate debris balls, a sign of a tornado on the ground.

What does purple rain mean on radar? ›

Purple returns on Doppler radar would indicate extreme amounts of precipitation. Caution should be used in low lying areas do to most certainly flooding conditions. It would be common to see purple in the areas of a hurricane land fall area that could possibly receive 16+ inches of rain fall per hour.

The colors are typically a spectrum. The greens indicate light or moderate rainfall. Yellow, orange, and red indicate moderate to heavy rainfall and can also indicate hail. Whites or blues mean snowfall and pink indicates freezing rain, sleet, or a wintry mix.

Radar, which is an acronym for radio detection and ranging, uses electromagnetic waves (EW) within the radio frequency (RF) spectrum to detect, locate, track, and identify objects of interest on the ground or in the air over long ranges.

While latency exists in every NEXRAD image, it will be exacerbated in these locations. While black on a radar display may represent an area with little or no precipitation, there are several scenarios where serious hazards may be cloaked in black.

Warm colors (red) / positive values indicate wind moving away from the radar (along a radial). Cool colors (green) / negative values indicate wind moving toward the radar. Purple indicates “range folding”— where the radar cannot determine the radial velocity. Velocity image of a large-scale weather system.

Global models with worldwide weather forecasts

These models are all generally fairly accurate in predicting large scale patterns/features, but all will become less accurate through time. The ECMWF is generally considered to be the most accurate global model, with the US's GFS slightly behind.

ForecastWatch is the only globally recognized measure of forecast accuracy. Of all commercial weather providers, The Weather Company is the most open about what goes into our forecast, how we create it, and how that is measured.

One of the best ways to track a thunderstorm is through a weather radar. This is an absolute essential when it comes to storm chasing. It can't just be any weather radar; it must be a highly reflective Doppler radar. This will give you accurate and timely data for your location.
