Some Local Doppler Radars are Slower Than Others

With all the rain we've had over the last few days, no doubt many of you have been keeping an eye on radar offered on dozens of Web sites and smartphone apps. But, have you ever looked at the time stamp on those radar images? You should, because not all radars are equal.

In looking through the radar of all the local television stations, the Houston Chronicle, the National Weather Service, (probably the most popular) and Weather Underground, I found that many of them showed images that were well behind current time. In the event of a dangerous thunderstorm, this kind of lag is downright worrisome.

Here they are with screen capture images from best to worst.

Note: Actual time was taken from a computer clock synced with an online server and should be considered highly accurate, though I wouldn't consider this test exactly scientific either.
