![]() ![]() If the radar animation of the last hours shows local thunderstorms or precipitation cells forming and disappearing in an irregular manner, then the forecast is not vey accurate. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created. Real weather is more complex than just the displacement of existing precipitation cells. Images: A large tornado scar can be seen to the southwest of Winona, Mississippi. This scar was so large that it was clearly visible when the Sentinel-2 L2A satellite passed over the region on Sunday, March 26, two days later. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. One of Friday night’s EF-3 tornadoes left a 24 kilometre-long scar across the landscape to the southwest of Winona. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future.

Netherlands: How accurate is the radar based forecast? Fresno news, breaking news and local news from the Central Valley. Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. The 3D KMZ Export of Weather Radar files produces KML/KMZ format files which contain a georefereced rendered image overlay draped on a COLLADA model representing the center of the Radar beam height. ![]() Note that lightning is not shown on the forecast, as it cannot be predicted. One of Friday night’s EF-3 tornadoes left a 24 kilometre-long scar across the landscape to the southwest of Winona. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms.Ĭurrent lightning strikes are marked with small orange dots on the map (Europe only). ![]() The different colours indicate the intensity of rainfall or snowfall. The radar map is updated every 5 minutes with a new radar observation. Along with the wet weather, hailstorms and gusty winds reaching 30-40 kmph are also on the cards for isolated locations across the region for the next 48 hours. The weather radar ( Netherlands) shows where it is currently raining or snowing. ![]()
