Not at all, but I don't think that's quite what I said, or at least
that was not my intention. I said "storms can jump ahead " and
probably should have said storm/cell formation can jump ahead, and "I
watched a line form". IOW a large area can go down in just minutes
giving the appearance the line is moving that fast. All too often we
think of a storm or line of storms moving, but many times what happens
with a large area of instability be it associated with a front or not,
they can give the impression of fast moving storms when it's really an
area of forming storms which was the case above.


actually.. i think we are in 'violent agreement' Just describing
it differently...

but I would like to clarify...for those who arent wx geeks...

storms..or any wx...can't JUMP ahead...it may look that way cuz
nexrad's only painting it in full once every 6 mins. and add some
unpredictable network delay, whether you're at home or in the plane...

The speed of the storm may change, but it can't "jump" to a new
location.

With the right conditions....small intense storms may continually pop
up in front of the line...rain out and die., called..."popcorn
storms"
