Does it mean when California gets hot on its side of the Rocky Mountains the rest of the country on this side will have a very cold winter?

The Rocky Mountains are nowhere near California.

To a certain extent ... when it's 'hot' west of the Rockies during the winter months ... it tends to be cooler to the east. This happens when there's a ridge of HIGH pressure over the western states and a trough of LOW pressure over the east.
Meteorologists look at how the wind flows ~three miles above the surface and compute indexes known as the Pacific-North American (PNA) and the Eastern pacific Oscillation (EPO).
A PNA > 0 means there's a warm ridge of HIGH pressure over the west and a cool trough over the east. The opposite is true when PNA < 0.
The EPO is similar; although the signs of the index are reversed from the PNA. AN EPO < 0 means there's a warm ridge of HIGH pressure over the west and a cool trough over the east. The opposite is true when EPO > 0.Source(s): Meteorologist.

Not really, no.
