Hourly Forecast 7 Day Radar Weather Alerts WEATHER STATS AND FACTS. weather dependent measurements 11 p1544 N82-20744 The MESOKLIP experiment. 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. Videos Firefighting program cut in Alberta could. Current conditions and forecasts including 7 day outlook, daily high/low temperature, warnings, chance of precipitation, pressure, humidity/wind chill (when. The visibility maps have been created for turbine models with turbine tower heights of 100 meters and blade lengths of 50 meters (for a total blade height of 150 meters). 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. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. American Meteorological Society, Boston. The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future. Weather Radar tornadic vortex signature detection algorithm. Find the most current and reliable 7 day weather forecasts, storm alerts, reports and information for city with The Weather Network. Due to the use of extrapolated data, however, some caution must be. 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.Īlberta: How accurate is the radar based forecast? Heres what it looked like for those with clear skies. Note that lightning is not shown on the forecast, as it cannot be predicted. 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. Alberta Weather Radar More Maps Radar Current and future radar maps for assessing areas of precipitation, type, and intensity Currently Viewing RealVue Satellite See a real view of Earth. The radar map is updated every 5 minutes with a new radar observation. The weather radar ( Alberta) shows where it is currently raining or snowing.
