![]() Therefore, it is advisable to spread the radar measuring stations over a large area to get an accurate picture of the rainfall. In physics, this means the divergence of the radiation emitted by the station. The reason for this is the divergence of the emitted electromagnetic rays. Now it is the case that the accuracy of the measurement decreases with increasing distance. ![]() Only then can a concrete picture of precipitation in the area emerge. To display these results in a radar image, one needs not only one, but several stations at different locations. ![]() How is a weather radar created?Īs you already know, the radar station and its radar beams are used to measure the amount of water vapor present in a cloud. Only the use of new types of radar technologies, such as the Doppler radar, made this possible. …that the first weather radar was already built in the early 1940s? However, this type of weather radar could not accurately predict the intensity of the rain or the strength of the thunderstorm or storm. This central computer is responsible for processing all the collected data and using it to create a picture of the general weather situation. These weather stations are linked to each other and transmit the collected data to a central computer. To be able to make a concrete weather forecast and to collect and analyze the data over a large area, many different weather radar stations are required at various locations. What is a weather radar live?Ī weather radar live is a special type of radar that collects and analyzes data on the weather situation. You can also zoom in with your fingers or the mouse wheel. Use the + or – at the top right to zoom in. By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. This is how the weather radar live works: If you have plans outside tomorrow, make sure you have a plan in case severe storms develop, and stay with Minnesota’s Weather Authority for the latest forecast.Depending on the intensity, the precipitation appears on the rain radar in the colors blue (weak precipitation), green, yellow, orange (moderate precipitation), red or purple (very heavy precipitation). Thunderstorms and lightning strikes are indicated by a small lightning symbol. ![]() If we have rain and storms linger longer through the morning, that could impact the coverage of late afternoon and evening storms Any storm that develops Wednesday afternoon and evening could have large hail, strong winds, and an isolated tornado. That should allow the atmosphere to rebound nicely, increasing the risk for severe weather later in the day. Right now it looks like there will be a mid-morning through mid-afternoon lull in storm chances. So the morning scattered showers and storms are not the round of active weather that poses the main severe weather threat for the day. While a few strong storms are possible overnight tonight across far western Minnesota, the greatest risk for severe weather is Wednesday late afternoon 3PM through about 10 PM. The risk for severe storms is greatest across central and southern MN into western Wisconsin. Isolated severe storms are possible, and some could have big hail, strong winds, and isolated tornadoes.įorecast First Alert is in place for tomorrow, specifically for Wednesday afternoon and evening. Minnesota’s Weather Authority is calling a Forecast First Alert for Wednesday afternoon and evening. Here’s your Tuesday evening forecast for Jfrom Minnesota’s Weather Authority and Meteorologist Wren Clair. ![]()
