Jet stream not as popular?

I've noticed that the jet stream has been played down lately, or so it
seems. It's not used on Washington DC's channel 4, not used in the
weather channel's weekly planner, and on web sites it's not shown as a
long green authoritative stream of air, but more as little pieces here
and there.

Is this a sign that the jet stream is not thought to have as much
control of weather patterns such as droughts and heavy snows as
previously thought?
