Steve: How accurate are the radars these days? I noticed on the Fox19 Weather Tracker app. that at around 1350hrs today that it showed a shower over Hamilton, but as I looked out the window the sun was shining and there were only scattered clouds. As I zoomed into my street on the radar it showed I was right in the middle of this shower. Just wondering what the error rate is and what would cause the radar to track a shower that didn't look like usual ground clutter echos?
