    Saw these associated with severe WX at KSDF on Monday afternoon. I wonder if they indicate squall line direction of movement and predicted distance traveled in a fixed unit of time. I'd welcome an informed response also!

    Storm track movement along the line where each black dot represents 5 minute increments.

    Thats good to know. I hope the blue dot wasnt your location in the air. I was at the Lancaster airport looking at an airplane when those tornadoes came through a couple of weeks ago. Should have had my ForeFlight.

    The black dots represent the number of times the pilot said "That was stupid I'll never do that again" by the ten thousand mark.
