You won't see this on a weather radar.. only on mosaic. Look where I've drawn around.. watch for big earthquakes there.. I've been seeing this lit up a a lot lately. What it is is high frequency being picked upon the conus radar. These frequencies are not being picked up on other radars (like weather).. they are "ghost storms" meaning that they are false signals being sent out by who knows.. I believe these high frequencies might involve haarp and big (5.5M and up) earthquakes. Keeping track of days like these.. Heads up Central and Coast of Cali...
