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 like the NWS forecasts more than BestForecast’s, there’s a toggle switch to get that data instead.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. Near my current address in Palo Alto, Calif., BestForecast is Good while the NWS is Fair, which means it is sometimes off by 3.5 degrees Celsius. Near my old house in the Sunset, BestForecast’s recent record is rated “Excellent” (meaning it predicted the high temperature to within 1.5 degrees Celsius) while the NWS is only “Good,” meaning it was up to 1 degree worse. If you scroll down the page on any forecast, the site will tell you how well BestForecast has performed for your area over time, and how well the Weather Service has as well. But Weather Underground is transparent about its performance. “It’s probably 1 or 2 Fahrenheit degrees better overall,” Celenza says when I press him to give me a ballpark figure, but he notes that that’s just an average-in some places BestForecast could be significantly better than the weather service (and, in some places, it could be worse the weather is unpredictable, after all). Because the weather varies so much from place to place, the quality of Weather Underground’s forecasts-and its relative performance compared to NWS-depends on where you’re talking about. How much better? That’s hard to quantify.
